Soil pollution with heavy metals is considered a serious issue affect human, animal, and plant. Owing to the deficiency of water supply in arid and semi-arid areas wastewater may be used in agricultural sector without carrying out the appropriate remediation that may increase pollutants content. Recently, we have introduced a new variation of soil electrokinetic remediation (SEKR) known as vertical anode-perforated cathode pipe SEKR system (VA-PCPSS) to overcome obstacles found in the regular PCPSS design. In the present study, the behavior of associated elements existed in anionic and cationic forms such as vanadium (V), chromium (Cr), Lithium (Li), and barium (Ba) during electro-remediation using the PCPSS and the VA-PCPSS techniques was investigated. The results indicated that, the VA-PCPSS did not affect negatively on vanadium distribution throughout soil specimen compared with sever accumulation adjacent to horizontal anode in the PCPSS design. Chromium showed the same behaviors of vanadium during SEKR of heavy metals. Lithium accumulated in the middle of specimen in either the PCPSS or the VA-PCPSS. Barium removal was 50% in the zone adjacent to anode, however sever removal was observed in the subsequent layers of the PCPSS. The application of the VA-PCPSS decreased the removed barium throughout soil, however it accumulated in the zone adjacent to specimen surface.

In the present work, Sr2+ contamination in some salt affected soils along the Western North coast of Egypt was investigated. The contamination of Sr2+ in different soils samples was evaluated using different risk indices such as enrichment factor (EF), geo-accumulation index (Igeo), contamination factor (CF), the degree of contamination (Cd), modified degree of contamination (mCd ), pollution load index (PLI), soil pollution index (SPI), and ecological risk assessment (RAC). The concentrations of Sr2+ were investigated according to the bioaccumulation (BAC) in different plant species such as tomato (Solanum lycopersicum), leek (Allium ampeloprasum), barley (Hordeum vulgare ), olive (Olea europaea) , alfalfa (Medicago sativa ), sweet sorghum (Sorghum vulgare var. sacchratum), fig ( Ficus carica), apple (Malus domestica), mountain spinach (Atriplex hortensis), onion (Allium cepa), eggplant (Solanum melongena), camphor (Cinnamomum camphora ), faba bean (Vicia faba), galawein (Sonchus oleraceus L.), and orange (Citrus Sinensis). The obtained results showed that, the mean value of EF for Sr2+ was the highest (15) among the other associated elements. Although, the highest Igeo values was observed with Zn2+ followed by Cd2+ and Sr2+, Sr2+ is not belongs to contamination category. According to CF index, Sr2+ is classified as low degree of contamination. According to mCd classification, Sr2+ contamination level is belongs to nil to very low degree of contamination class. The SPI presented that Sr2+ is considered moderate to highly contamination element. The highest values of BAC was found to be 2.018 in leek, while the lowest BAC value was 0.005 in tomato. To compare the concentration of median Sr in the studied area with its concentrations in the land of the African continent and the world, the median Sr in the western north coast of Egypt (449 mg/kg) appear to be very close to the empirical data value from Africa and higher than the empirical data value globally.

Field trials were carried at El-Ashartalaf feddan region, Behaira government, Egypt during two successive seasons of 2016 and 20117 to evaluate four insecticides and three of their mixtures against the tomato leafminer Tuta absoluta under field conditions. The seven evaluated insecticidal treatments were applied in three consequent sprays within an interval of 10 days between each in addition to the treatment of untreated check. The lonely or individually evaluated insecticides included chlorantraniliprole, thiamethoxam, lufenuron and chlorpyriphos which have been sprayed according to the recommendations of the Egyptian Ministry of Agriculture. Meanwhile, their evaluated mixtures: chlorantraniliprole + thiamethoxam, chlorantraniliprole+ lufenuron and thiamethoxam + lufenuronwere were applied at the rate of half recommended dose of each insecticide within the tested mixture. The obtained results showed a more or less toxic efficiency of the individually and/or admixed insecticides against the insect throughout both the seasons of 2016 and 2017. In the first season of 2016, the mixture of chlorantraniliprole + lufenuron was comparatively high effective during the elapsed period after the 1st and 2nd spray; furthermore it was proved to be the utmost superior efficient post the 3rd spray achieving complete infestation reduction (100%) of larvae. During the second season of 2017, chlorpyriphos was the most effective tested individual insecticide. The mixture of chlorantraniliprole + lufenuron was proved again to be superior achieving reduction level of 100% after the 3rd spray. Therefore, this mixture would be recommended for achieving efficient control of T. absoluta in the growing tomato plants under field conditions. It is also better to use chlorpyriphos alone in IPM program to reduce the costs and slow down the development of resistance of this insect-pest to other involved compounds in the mixtures.

Field experiments evaluation were carried out in a private orchard cultivated with olive trees of (Manzanillo cultivar) at Wady El-Natroon region, throughout two subsequent seasons of2016 and 2017 to control both of the lepidopteran olive moths; Prays oleae and the jasmine moth, Margaronia unionlis. Five treatments was applied; the release of the parasitoid-Trichogramma evanescens alone or followed with certain insecticides. The results showed that the subsequent monthly use treatment of release the parasitoid-T. evanescens then Nimbecidine® 0.03% E.C against P. oleae gave the best efficient treatment recording higher infestation reductions of 83.41 and 82.12% in both seasons of 2016 and 2017, respectively, followed by the more or less efficiency bimonthly release of the T. evanescens then Nimbecidine® 0.03% E.C, Nimbecidine® 0.03% E.C, Deltachem Super® 2.6% E.C, and release of T. evanescens only, that gave 60.11 & 67.88%, 57.85 & 64.63%, 55.16 & 56.91% and 52.48 & 53.66%, respectively. As for the M. unionlis the results indicated that the subsequent monthly use treatment of release the T. evanescens then Nimbecidine® 0.03% E.C gave the best efficient control recording higher infestation reductions of 86.89 & 80.39% in both seasons 2016-2017, respectively, followed by the performed treatment of Nimbecidine® 0.03% E.C, the bimonthly release of T. evanescens then Nimbecidine® 0.03% E.C, Deltachem Super® 2.6% E.C, and release of T. evanescensonly, that gave infestation reductions amounted to 77.75 & 68.81%, 70.73 & 64.31%, 70.43 & 63.99 and 60.37 & 52.09%, respectively. Therefore, the monthly hang of the cards of parasitoid-T. evanescens followed by Nimbecidine® 0.03% E.C application at the following month could be recommended as effective of control both the insect-pests.

Modulation of Abamectin and Indoxacarb -Induced Toxicity on Male Albino Rats by Moringa oleifera
Mona A.
Abdelrasoul
Pesticide formulations are characterized by its complex mixtures.The available toxicity information on the active ingredients alone is not quit enough to evaluate the risk of undesirable health effects of commercial pesticides. Therefore, the present study was proposed to clarify the adverse effects of exposure to formulated abamectin (ABA) (0.5 mg/kg bw, 1/20 LD50), indoxacarb (IND) (86.6 mg/kg bw, 1/20 LD50 ) and their combinations on some haematological and biochemical parameters and histopathological changes of male rats given repetitive oral doses for 30 consecutive days. The protective effect of aqueous extract of Moringa oleifera leaves (MO) against toxicity induced by tested insecticide was, also, considered. Results indicated that ABA, IND, and their combination treatments, significantly, caused gradual decreasing in body weight, erythrocyte counts (RBCs), haemoglobin concentration (g/dL), haematocrit (%) and platelets (PLT). However, significant elevation in the relative liver, kidney and brain weights were associated with these treatments. Marked and significant increments in the levels of serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (γ-GT), glucose concentration and creatinine (Cre), while decrease in serum acetylcholinesterase (AChE) activity was observed due to tested insecticide treatments. Exposure to ABA and IND, significantly decrease the total protein and total antioxidant scavenging activity. Histological studies confirmed the biochemical parameters. M. oleifera leaves-treated rats with ABA, IND or their combinations showed marked improvements of hematological, biochemical parameters and histopathological changes, indicating that MO extract bear a potent antioxidant activity. Therefore, the successive aqueous extract of MO as an herbal tea may be beneficial for patients who suffer from liver, kidney and brain diseases and restoring the damage sustained by insecticide exposure.

Mahmud A. A.
Rahuma
A field experiment was carried out at Agricultural Research Station, Faculty of Agriculture, Saba-Basha, Alexandria University, Egypt, during 2017 summer season to study growth and productivity of four maize hybrids (S.C.10, S.C. 168, T.C. 310 and T.C. 352) under four sowing dates (mid April, mid May, mid June and mid July) using split-plot design in three replications. Early sowing (mid April) produced the tallest plants and ears (242.30 cm and 25.49 cm), respectively, and largest ear leaf area (880.38 cm2). However, maize sowing in mid May led to increase in ear height (168.14 cm) and produced the maximum number of rows/ ear (14.62), weight of grains/ ear (200.11 g), 100-kernel weight (33.26 g), shelling percentage (83.68%) and grain yield (3.64 t/ fed.). Conversely, delayed sowing produced the significantly lowest values for all the studied traits. Single crosses, especially, white grains S.C.10 was superior than yellow grains S.C.168 and the three way crosses for all the studied traits. However, white grains T.W.310 showed the highest ear height (168.76 cm). Single cross 10 sown early (mid April) produced the tallest plants and largest ear leaf area, while sowing it in (mid May) produced the maximum grains weight/ ear, 100-kernel weight, shelling percentage and grain yield (4 t/ fed.). Sowing S.C. 168 in mid May gave the tallest ears (28.03 cm).

Physico-chemical , microbiological characteristics and sensory evaluation were performed to investigate the effect of replacing sugar with stevioside as well as the addition of texturizing inulin as a functional ingredient on the quality of the low calorie chocolate milk. Low caloric chocolate milk has been prepared by replacing 25, 50, 75 and 100% of sugar with stevioside and addition of inulin (frutafit® TEX) to improve texture parameters. The results indicated that the total soluble solids of all chocolate milk decreased as the ratio of the stevioside added increased compared to the control samples. No significant differences were found between the organoleptic properties for all samples sweetened with stevioside compared to the control. The addition of 2% inulin increased the chocolate milk viscosity. Chocolate milk samples replacing 50% sugar with stevioside and 2% inulin had gained the highest overall acceptability scores compared to those prepared using sugar alone and qualities of similar textures of full-fat products. These low products can be used for people suffering from obese and diabetics.

Reuse of agricultural waste materials is a smart solution for reducing their environmental impacts and increase economic value. Spent coffee grounds (SCG) is worldwide generated in tremendous amounts. The objectives of this study were to optimize a method to extract humic-like substances (HLS) from SCG using KOH extractant, prepare a liquid organic-mineral fertilizer enriched with N and P in addition to K, and to evaluate this fertilizer on growing maize (Zea mays L.). HLS extracted from SCG increased with KOH concentration up to 3 N and with extraction ratio up to 1:10 at room temperature. Increasing the temperature to 50 and 80 °C and contact time up to 3 h, significantly enhanced HLS recovery. Therefore, the optimum conditions for maximum HLS extraction were; 2 N KOH, SCG-to-extractant ratio of 1:10, 3 h of contact time, and 80 °C. Adjusting the pH of the alkaline K-HLS supernatant to pH 6 was achieved using a mixture of HNO3 and H3PO4. The prepared NPK mineral-organic fertilizer (NPK-HLS) was dark brown containing 2.0/5.8/8.6 as N/P2O5/K2O and 5.1 %w/v HLS. The produced fertilizer was evaluated for its effect on maize plants grown in a calcareous soil low in available nutrient using a CRBD pot experiment. Two application rates of NPK-HLS (NPK-HLS1 and NPK-HLS2) based on P rates, 125 and 250 mg P pot-1, with and without a basic fertilizer (BF) were applied. Both NPK-HLS1 and NPK-HLS2 rates significantly increased shoot dry matter, NPK uptake and availability in soil compared to the control, but did not significantly affect root dry matter. Increasing the application rate to NPK-HLS2 did not further increase dry matter or NPK uptake. No significant effect was found for BF for all measured variables. Results of this study showed that the extraction of HLS from SCG and its incorporation into a liquid fertilizer could be an alternative solution to the reuse of SCG.

Two field experiments were carried out in 2013/2014 and 2014/2015 seasons at Nubaria Research Station, El-Beheira Governorate, Egypt to study the response of three sugar beet cultivars to the foliar nutrition with pigeon manure tea (PMT) in combination with soil N fertilizer and its effect on yield, yield components, chemical constituents and some physiological and genetical parameters. A split plot arrangement in a Randomized Complete Block Design with three replications was used. Three polygerm sugar beet cultivars namely SN-626, NH-627 and Hercule were randomly distributed in the main plots, while the four combinations of PMT and N fertilizer were randomly distributed in the sub-plots, it was as follows; 80 kg N/fed (recommended level) was given as soil application, without PMT (check treatment) (C1), foliar application of 2.5% PMT + soil addition of 40 kg N/fed (C2), foliar application of 5% PMT + soil addition of 40 kg N/fed (C3) and foliar application of 10% PMT + soil addition of 40 kg N/fed (C4). The results illustrated that fertilizing the tested cultivars with (C4) treatment attained the highest mean of sugar yield compared with (C2) and/or (C3), in the two seasons. The three cultivars showed that the highest and the least values of root, top, sugar yields and sucrose% were produced from SN-626 and Hercule cultivar, respectively, in both seasons. Genotypic and phenotypic variances, heritability and coefficient of variance as percent of means were estimated for the studied traits. Maximum heritability values were obtained for root diameter followed by top yield. Meanwhile, it was moderate for sugar yield, sucrose% and root yield, while the minimum values of heritability were recorded by total soluble solids and purity percentages. Besides, different genetic coefficient of variance as percent of mean, as well as high genetic variability and high range of variations were detected. Path-coefficient analysis revealed that the improvement of different genotypes sugar yield can alter the relative importance of root yield, sucrose% and purity%. Under conditions of the present work, it can be recommended that growing SN-626 variety fertilized with (C4) treatment produced the highest sugar yield/fed with no significant difference from treating the same variety with C1 (recommended level). Also, the data suggest that significant improvement could be achieved by increasing purity as well as sucrose percentages to increase sugar yield.

There is an increasing need to improve the fodder productivity of the common forage crops grown in the summer season in Egypt. Fertilizer management is among the common cultural practices that have a direct influence on the forage yield and growth attributes. This study was carried out during two successive summer seasons (2014 and 2015) in Egypt and aimed to investigate the variations in yield and some agronomic characteristics of three successive cuts of five fodder pearl millet cultivars under integrated use of nitrobine bio-fertilizer with different doses of mineral nitrogen fertilizer. The studied fertilization treatments were; 60 and 90 kg mineral N fed-1 alone and the same doses accompanied with nitrobine bio-fertilizer application. In addition to fresh and dry yields (ton fed-1), and dry matter content (g kg-1), the following agronomic characteristics were evaluated; plant height (cm), stem diameter (mm), number of leaves per plant, leaf area per plant (cm2), number of tillers (m-2) and leaf/stem ratio. A pronounced response in almost all the studied parameters to the different fertilization treatments was achieved for the three investigated cuts for both growing seasons. The application of bio-fertilizer accompanied with 60 or 90 kg N produced the highest significant fresh and dry yields. No significant variation was detected among the tested fertilizer treatments for the dry matter accumulation of the 1st cut, while the application of 60 kg mineral N fed-1 in addition to bio-fertilizer accumulated the highest amount of dry matter for the 2nd and 3rd cuts. Similar to the yield results, the integration of bio-fertilizer with 60 or 90 kg mineral N fed-1 resulted in better growth attributes. Giza 1 and Giza 2 proved to be high yielding cultivars with superiority in the studied growth attributes. Meanwhile, Shandaweel 1 and Sharq El Owainat were inferior to the other cultivars. Investigating the three successive cuts revealed that the values for all the studied parameters were the highest in case of the 1st cut and then gradually decreased till reaching the lowest values for the 3rd cut. It is recommended to integrate nitrobine bio-fertilizer with low doses of mineral N fertilizer in the production of fodder pearl millet.

The objectives of this study were to find the correlation between population dynamics of the whitefly, Bemisia tabaci, Phaseolus vulgaris cultivars, temperature and humidity during the summer and winter growing seasons of 2013 and 2014. The three P. vulgaris cultivars screened were Copy, Polesta and Manga. In 2013 and 2014 cropping seasons, the population densities of B. tabaci gradually increased from the 3rd week of March until the 4th week of April. For, the population density increased and reached a peak from the 1st week of May, and then the population density decreased gradually from the 4th week of May until the 3rd week of June in 2013 and 1st of June in 2014.Densities of this pest typically increased as the growing season progressed andreached a peak in November and started to decrease from 1st of December until the end of them. In 2013 and 2014 cropping seasons, the population densities gradually increased from the 2nd week of October until the 4th week of October. Furthermore, the population density reached a peak from the 1st week of November, and then decreased gradually from the 4th week of November until the 4th week of December in 2013 and 2014. In 2013 summer cropping season, the cultivars Copy and Polesta were the most infested varieties. A similar trend was observed during 2014 summer growing season. In 2013 winter cropping season, the cultivars Copy and Manga were more susceptible to white fly infestation than Polesta cultivar. A similar picture was obtained during the winter cropping season of 2014. The most infested varieties were Copy and Manga respectively. Whereas Polesta variety was the least infested. B. tabaci population density was positively affected by temperature in 2013 and 2014 summer growing seasons, where the correlation coefficient were 0.64 and 0.6, respectively. In contrast, in 2013 and 2014 winter cropping season the relationship between B. tabaci population and temperature was insignificant and/or significant and negative with a correlation coefficient of -0.14 and -0.61 respectively. The results revealed that the relative humidity showed non-significant positive association with B, tabaci abundance in 2013 summer growing season with correlation coefficient of 0.08. On the other hand, B. tabaci density showed non-significant negative association with relative humidity in 2014summer season and 2013 winter seasons and significant negative association in 2014 winter season with correlation coefficients of 0.18, 0.73 and 0.32 respectively.

This investigation was conducted at Gemmeiza, Agric. Res. Station, El –Gharbia Governorate, Agricultural Research Center (ARC), Egypt, during the period between 2014 and 2015 summer seasons to evaluate eight selected teosinte genotypes. The experimental design was a randomized complete block with three replicates. The data measured were fresh yield (fr) and dry yield (dy) over the consecutive cuts. Plant height (ph), stem dimeter (SD), number of leaves on the main stem (NL), leaf area per plant, dry matter (DM), fresh yield, dry yield, fresh leaves / stem (%) and dry leaves / stem (%) and were recorded at cutting time. Heritability estimate, in the broad – sense (h2b), on mean basis for traits, were carried out. Genotypes 3 and 4 were the superior to the other tested genotypes in morphological characters in both seasons. The heritability was high in fresh yield (fy) (99.9%) and dry matter (DM) (99.8%), followed by plant height (99.5%) and leaf area (99.5%). (SDS – PAGE) official sodium dodecyl sulphate polyacrylamide gel electrophoresis was employed to detect variation in total soluble protein content technique among the eight genotypes of teosinte; namely, 1, 2, 3, 4, , 6, 7 and 8 genotypes. Different protein fragmentation was recorded for the teosinte genotypes, which ranged from 21 to 16 for 1, 2, 3 and 4 genotypes repectively, with molecular weight (MW) ranged from 154 to 7 kda. It was found that similarity and dissimilarity, for protein patterns of teosinte genotypes, showed that 3 and 4 genotypes showed the same protein patterns, with almost protein loci and molecular weights, with 18 and 16 protein bands. According to electrophoretic study. Phyllogenetic tree was constructed and indicated a clear genetic base from SDS – PAGE analysis, high similarity percentage i.e. (94.5%) for genotype 3, and the lowest similarity percentage (76.2%) for the fist genotype.

Water is the most basic element for the life on earth. Reliable access to cleanly and affordable water is considered main challenge for the total world. Along with waste water progress, environmental pollutants like toxic heavy metals are widely spreading throughout the world. The presence of heavy metal in aqueous environment poses a dangerous environmental risk.The utilization of heavy metal resistance bacteria might avail a cost-efficient tool for bioremediations of contaminated water bodies. During our screening program for heavy metal resistant bacteria isolated from agriculture wastewater sample collected from mainsheet El Awqaf near kafr el-Dewar), EL-Bahaira Egypt was able to grow on (LB) medium supplemented with Cadmium (50 to 500 mg/l),six isolates were chosen (4(DB-3), 5(DB-3), 6CB-3), 7(CB-7), J (CB-5), and M (CB-3) based on the metal tolerance concentration (MIC) values these isolates were gram negative rod shaped bacteria.

Anwar
The present study aimed to evaluate B status of grape (Vitis vinifera L.) received drip irrigation from blend water source (Neil Rever water mixed with agriculture drainage). Some plots in two farms representing sandy non-calcareous and calcareous soils were selected. Soil samples were collected at three intervals of 0 – 90 cm depth at the beginning of the season and analyzed for hot water extractable-B, organic matter (OM), soil salinity (ECe), and CaCO3 content. B was measured in the applied compost and monitored in irrigation water, petioles, and leaves of the growing grape. Results indicated that the estimated B input per year was 1.87 kg B ha-1from the irrigation water and the applied organic compost. The hot water extractable-B was higher in the calcareous than that in the sandy soil and tended to increase with soil depth in both soils with higher magnitude in the calcareous soil profile. Regardless soil type, extractable-B was correlated with CaCO3 content. Consequently, average of B concentration in petioles of grape grown on calcareous soil was 64.4 ±11.6 at flowering which increased to 84.5 ±8.5 mg B kg-1 DM at veraison stage compared to values those did not exceed 58.7 at both stages in sandy soil. Monitoring of B in leaves clearly showed accumulation with time where the highest B concentration was observed at the post harvest stage with an average of 120.7 ±17.0 mg B kg-1DM in the old and 123.3 ±13.4 in the young leaves of grape grown on the calcareous soil. Regardless of the soil type, significant positive relationship was obtained between B concentration in the old leaves and hot water extractable-B from soil at flowering and veraison stages. The predicted critical B concentration in soil was 2.3 at flowering and 1.8 mg kg-1 soil at the veraison stage. The high temperature during the veraison stage is expected to enhance the transpiration, water uptake, and B uptake and concentration in leaves and, therefore, the critical level of B in soil should be kept at lower level than that at flowering.

Ahmed F.
Saad
Laboratory Experiments were conducted on the effects of surface and incorporating different rates of rice straw (RS) on evaporation rate and infiltration rate of two sandy soils, differ in sand fraction less than 250 µm (coarse sand (S1) and,fine sand, S2,) at three levels of RS application: 0.0, 1 and 2% on weight basis. It was observed that there was a significant effect as a result of adding different rates of rice straw (quantity or thickness of the layer), the addition methods of rice straw, percentage of the sand particles with a diameter less than 250 µm and the period between the drying and wetting cycles at p < 0.05 on both evaporation rate and accumulation evaporation of the two sandy soils at subjected to successive drying and wetting cycles (at different periods 4, 7, 11 days). Total cumulative infiltration in control (ZC), at 90 minutes, was reduced from 68.46 cm in S1 to 40.52 cm in S2( about 1.69 times) as the fraction of sand particles < 250 µm was increased from 47.44% in S1 to 72.08% in S2. The values of total cumulative infiltration, over 90 minutes, were reduced to 51.56 cm (24.7%) and 25.73 cm (62.4%) compared to the control treatment (68.46 cm) in sandy soil (S1) incorporated with1% and 2% of rice straw, respectively. The results showed that the incorporated 1% and 2% of rice straw with soil (S2) reduced total cumulative infiltration by 47.1% and 57.8% compared to control. The results showed that the incorporated 1% and 2% of rice straw with soil (S2) reduced total cumulative infiltration by 47.1% and 57.8% compared to control. The (Ib ) value was reached to 5.78 cm/hr (60% reduction compared to control) when S2 mixed with 2% of rice straw.

A field experiment was carried out in the fields of the Department of Field Crops/ College Agriculture - University of Anbar (Abu Ghraib) during the spring and autumn seasons of 2017. The aim of this study was to deterimnie the effect of conservation agriculture at three tillage systems (no-tillage (T1), surface tillage (T2) and conventional tillage (T3)) and three plant densities )66666 (D1), 57143 (D2) and 50000 (D3)( in plant growth and yield of two composit varieties of maize (Maha (V1) and Fajr 1 (V2)). Split-split plots were used according to the randomized Complete Block Design (RCBD) with three replicates. The results were summarized as follows: No-tillage system (T1) was superior of the surface tillage and conventional tillage (T2 and T3) in weight of 300 grains for spring and autumn seasons. And the same tillage system superior in autumn seasons in plant height, No. of ears per plant and grain yield (6.92 ton ha-1). The increasing plant density significantly increased leaf area, weight of the grain and grain yield, which reached 4.97 ton ha-1. The high density of the plant was (D1), and the medium plant density (D2) were higher in some traits such as plant height for spring and autumn seasons .The cultivar Maha (V1) was superior than the Fajr 1 cultivar (V2) in some traits, including plant height, flage leaf area and weight of the grain, grain yield (6.70 ton ha-1). The effect of interaction between the tillage systems and the plant density was significantly differed in several traits, where (D2 × T1), produced the highest average of the plant charcters for the autumn season. While the combination (D3 × T1) gave the highest mean of No. of ears per plant (1.740) and the highest average weight of 300 grain reached 59.68 and 62.52 g for the spring and autumn seasons, respectively. The combination (V2 × T1) recorded the highest mean plant height, weight of 300 grains. The combination (V1 × D1) has the highest weight of 300 grains, and grain yield (9.85 ton ha-1)for the autumn season. (T1 × D3 × V2) gave the highest weight of 300 grains (60.33 g) for the spring season.

Two field experiments were carried out in EL-Wasiata district (EL-Jabal EL-Akhdar) during summer seasons of 2015 and 2016 to study drought effect for ten days during heading stage of maize (Zea mays L.) on yield and its attributes and grain oil and protein content of ten maize genotypes. Split-plot with four replication was used, where the two drought treatments were distributed as whole plot, while the ten genotypes were randomly allocated in sub plot. Obtained results revealed that the irrigation (non-stressed) treatment was significantly superior than drought (stressed) treatment for all the studied traits, except ear diameter in the two seasons.
Single crosses, especially Sc128 and Sc168 were superior than Triple crosses and open pollinated varieties for all the studied traits in the two studied seasons, except number of rows/ ear in the second season and ear diameter in both seasons, where the open pollinated varieties had the thickest ears.
Regarding the interaction between the two factors, results indicated that SC 128 and SC 168 under (non-stressed) treatment had the highest number of grains/ row in both seasons, while the heaviest 100-grain weight resulted from SC128 and SC30K8 in the first and second seasons, respectively, under non-stressed conditions. Also, SC 128 in the two seasons and SC 168 in the second season showed the highest grain yield under (non-stressed) condition.
