Zinc is an essential micronutrient whose deficiency is widespread in cultivated soils and affects the growth and productivity of many crops. The biofortification of highly consumed crops, including wheat, is a hopeful trend to enhance plants productivity and even human health, particularly in developing countries where diet is mainly dependent on grains. Different cultivars have different responses to metal treatment; therefore, it is crucial to select the suitable cultivar for each cultivation conditions. In the current study, two wheat cultivars, Sakha 94 and Gemmyza 10, were studied for their growth under different concentrations of Zn (2, 5, 10 and 25 mM) added to the soil. The experimented plants were assessed for a number of growth criteria (lengths, fresh weights, dry weights and water contents for both shoots and roots) and the contents of a number of minerals (Ca, Mg, K, Na and Zn). Zinc translocation factor, Zn accumulation in roots, shoots and total plants and Zn distribution in roots of the tested plants were estimated. The contents of soluble carbohydrates and proteins in roots and shoots were measured. The results revealed that cultivar Gemmyza 10 showed better growth under high Zn concentrations with general enhancement in plants physiological status and equal distribution of the absorbed Zn between roots and shoots. The other cultivar was superior in growing under control conditions while Zn treatment caused suppressed growth and disturbance in physiological parameters with localization of the absorbed Zn in roots rather than shoots. These results confirm the differential responses of different cultivars to Zn treatment and suggest Zn fertilization of cultivar Gemmyza 10, particularly by the 10 mM Zn concentration, for improvement of growth and physiology. Cultivar Sakha 94, on the other hand, is suitable for cultivation in low-Zn soils as its growth is suppressed by elevating Zn levels.

The present study has been carried out to highlight the optimal agricultural use of the different soil taxa units common in the Western desert fringe of El-Minia Governorate – Middle Egypt. This investigation is based on remote sensing data, GIS facilities, as well as outputs of the regular grid survey system. Geomorphologically, the whole area is an alluvial plain with different topography gradient varying from almost flat, gently undulating and undulating. Taxonomically, soils could be classified into (Typic, Lithic Torripsamments and Typic, Lithic Torriorthents – Entisols); (Typic, Lithic Haplogypsids and Typic Calcigypsids – Aridsols). Concerning the land suitability for crops, based on ALMAGARA model, “the deep and moderately deep, moderately coarse-texrured soils” vary between the suitable and moderately suitable classes (S2 and S3); whereas “the deep and moderately deep, coarse-textured soils” and “shallow soils” belong to the marginally suitable class (S4). The very shallow soils have been actually found not suitable for the tested crops. In terms of their suitability amplitude, the tested crops could be arranged as olive > peach > citrus > wheat > potato > sunflower > sugar beet > maize > melon > soybean. The study also indicated that about 32.3 % to 54% of the area regarded suitable for orchard, whereas 52% of the area is moderately suitable for the other crops and areas ranged from 5.3% to 11.8% are not suitable for the most tested crops. The outputs of this investigation may help in acquiring sustainable management and participatory agricultural development process for recently reclaimed desert areas.

A field research study was conducted at the experimental station of the Faculty of Agriculture, Alexandria University during 2017/2018 and 2018/2019 seasons to investigate the effect of three sowing dates (1, 15 and 30 November) and three phosphorus fertilizer rates (zero, 36 and 72 kg P2O5/ha.) on straw and seed yields and their components beside seed oil content of Sakha 5 flax cultivar. The obtained results showed significant effects for both sowing dates and phosphorus fertilizer rates, with significant interaction between them on seed index and number of seeds/ capsules in the second season (2018/2019) and seed weight/ plant in the two seasons. The first and second sowing dates were not significantly different from each other in straw yield/ha, but they significantly dominated over the yield of the third sowing date in both seasons. Straw yield/ha ranged from 7.45 to 8.16 t/ha in the first season and from 7.90 to 8.38 t/ha in the second season. The sowing date of 15th Nov. significantly increased number of capsules/plant and seed yield/ha more than the other two sowing dates. The highest seed yields/ha were 2.55 and 2.50 t/ha under 15th Nov. sowing date in the two seasons, respectively, followed by 30th Nov. date. Application of 36 kg P2O5/ha produced the highest means of straw yield and straw yield components but no significant differences were found between the 36 and 72 kg P2O5 /ha for these traits. The highest means of seed yield and seed yield components were detected under the 36 kg P2O5/ha rate with significant differences from the highest phosphorus fertilizer rate or zero phosphorus fertilizer. The highest oil percentages were 46.51% and 46.68% under the 36 kg P2O5/ha rate in the two seasons, respectively, followed by the highest rate while the lowest oil percentages were 45.09 % and 45.08% under zero phosphorus fertilizer in the two seasons, respectively. Regarding the significant interaction effect, the obtained results indicated that 30th Nov. with 36 kg P2O5 /ha gave higher values of seed index and number of seeds/ capsules in the second season, seed weight/ plant increased with both 15th or 30th Nov. under 36 kg P2O5 /ha in the first season, whereas in the second season the highest value was obtained for 15th Nov. under 36 kg P2O5 /ha.

This research aimed to compare the effect of post-manufacture thermal treatment and wax emulsion (1%) as an additive on water absorption, thickness swelling, and formaldehyde emission of particleboard produced from Ficus retusa branchwood. The particleboards were single layer produced with a target density of 690 kg. m-3 and 12% urea formaldehyde as a binder. Three different temperatures (180, 200, and 220 °C) and two different heat exposure durations (5 and 10 minutes) were applied. The statistical tests revealed that the post-manufacture heat treatments of the Ficus particleboard at 200 °C/10 min and 230 °C/5 and 10 min were effective in improving the dimensional stability (water absorption and thickness swelling) of the panels and reducing the formaldehyde emission. Additionally, using the 1% wax emulsion in the panels enhanced the dimensional stability and was comparable with the 220°C/10 min treatment, while it had no significant effect on the formaldehyde emission. Moreover, the F. retusa branchwood was suitable for particleboard production using the production parameters introduced in this study.

As a result of the arid climate of Saudi Arabia, groundwater is the most precious natural resource, providing reliable water supply for the resident population and the development of irrigated agriculture where surface water resources are insufficient and little to meet the water budget requirements of the Kingdom of Saudi Arabia. Therefore, this study was carried out to evaluate the quality of groundwater resources in selected locations of Hail region. This study focused on the important chemical analysis of the available groundwater resources in Hail region. Groundwater samples were collected from 61wells at different locations that cover the Hail region for chemical analysis. Parameters such as pH, electrical conductivity (EC), sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), carbonate (CO3--) bicarbonate (HCO-3), chloride (Cl-), and heavy metals were analyzed moreover the calculation of sodium adsorption ratio (SAR) to assess the suitability of groundwater for agricultural purposes. The pH values were between 7.10 and 8.23 (M = 7.66). The salinity of groundwater, as a primary indicator of water quality for irrigation, ranged between moderate and high (between 0.27 to 8.99 dS m-1) in most studied water samples. Besides salinity, 31.1% of Hail groundwater samples have the potential risk of chloride hazard (chloride > 10 meq L-1). SAR values were less than 9 for all groundwater samples while the heavy metals were within acceptable levels.

The seedlings growth media plays a very important role in factory seedling cultivation. High quality growth media could provide healthy and high-quality seedlings for high yield of vegetable crops. This study has attempted to use some agricultural organic wastes and mineral substrates, with differ rent ratios, as growth media mixtures. to select the best growth media, which are suitable for the growth of tomato seedlings (Solanum lycopersicum). Eighteen different (growth media) mixtures were prepared from mineral fraction (sand and vermiculite) and agricultural organic wastes Palme seeds, rice straw and coffee grounds) then compared. Seven growth media mixtures were selected based on the best growth performance of tomato seedlings. The experiment was arranged in a completely randomized design with 7 treatments and 3 replications with 5 observations per treatment. After the seedlings growth period, seedlings were harvested to determine the effect of the growth media mixtures on the different growth parameters (plant dry matter and leaf area) and (percentage of seedlings, fresh weight and chlorophyll content). The Highest seed emergency rate was achieved with T 13, T14 and T 15 mixtures and the next ones were obtained with T2 mixture. The emergency rates of all treatments were higher than control, and the lowest one was control., The results showed that SPAD value (leaf chlorophyll content) of T2 and 15 mixture was biggest for 47.18 and 46.2 followed insignificantly by T 5, T13 and T4, Which were 45.2, 43.55 and 41.96 and value for control was smallest which was 38.33 without significant difference than T 13, T14 and T4. It could be generally noticed that for fresh weight and leaf area characters, mixture of T15 (the commercial media with an addition 15% of date palm seed ground) had the highest values of plant growth and exceed the rest of the formulas followed by a mixture of T13 with a significant difference. Concerning, dry matter content the results indicated that T4, T5 and T2 of growth media mixtures achieved the highest values 11.78, 11.53 and 11.32 % for dry matter without significant difference. On the other hand, the control media mixture gave the lowest value of dry matter of the tomato transplants.

A study was conducted at Etay Elbaroud Research Station, Agriculture Research Center, MALR, Egypt, to investigate the effect of magnetic saline irrigation water on growth of two groundnut genotypes. The experiment was carried out in randomized complete block design in a split-split-plot arrangement with three replicates. The main plot represented by four salt concentrations (0, 25, 50 and 100 mM NaCl), the sub-plot was two groundnut genotypes (Giza 6 and N.C.) and the sub-subplot was two treatments (with or without magnetized irrigation solution). Seeds were sown in pots containing 0.5 Kg pre-washed quartz sand and irrigated three times per week by adding 100 mL of irrigation solution consisting of base nutrient solution and the salt level exposed to with or without a magnetic field, to each pot. After three weeks from sowing the whole plants were collected. The results indicated that increasing salt stress decreased the all growth parameters and shoot/root ratio on fresh and dry weight basis of the two groundnut genotype. However, moisture content of whole plant, shoots and roots were increased with increasing salt stress. Electrolytes leakage generally decreased with increasing salt stress. Chlorophyll a, b and total chlorophyll content increased at high level of salt stress (100 mM NaCl). The N.C. genotype was more sensitive to salinity than the Giza 6 genotype for most growth attributes. The magnetized saline irrigation water had no significant effect on alleviation of salt stress to the two groundnut genotypes.

This research mainly aimed at studying the extension needs of caraway farmers in El-Mesery Agricultural Cooperative-El Amereia - Alexandria Governorate.
This necessitated the achievement of the following sub-objectives: (1) Identify some of the respondents 'characteristics, (2) Identify the cognitive level of the respondents, (3) Identify the related and influencing variables on the cognitive level of the respondents, (4) Identify the respondents' trends towards caraway cultivation, ( 5) Identifying the related and influencing variables in the respondents ’attitudes towards caraway cultivation, (6) Identifying the most important problems they face in cultivating and marketing the caraway crop. The personal interview questionnaire form was used to complete the field data from a random sample of 200 respondents, and the percentages, range, arithmetic mean, standard deviation, frequency tables and simple correlation coefficient of Pearson were used in the presentation, discussion and analysis of the results. statistical analysis.The study concluded many research results, the most prominent of which are the following:
1-With regard to the characteristics of the studied caraway farmers, the research results indicated that 66%Of the total respondents, their ages are less than 40-53 years, and that (32.5%) of the respondents are illiterate, and that the farmers studied have all previously cultivated medicinal and aromatic plants, and the percentage of those with moderate experience reached 42.5%, of the total respondents
2-The low cognitive level in caraway cultivation is 15%, the average cognitive level is 69%, and the high cognitive level is 16%, and the results showed a positive and significant correlation at the probability level 0.01 Between the cognitive level of the surveyed farmers and each of the following independent variables: full-time agricultural work, the number of years of experience cultivating medicinal and aromatic plants, media openness, agricultural information sources, membership of organizations, opinion leadership, readiness for change, living satisfaction, level of ambition and direction towards agricultural extension. While that correlation was positive and significant at the probability level 0.05 with both age and educational level, while that relationship was negative and significant at the probability level 0.05 with the variable of agricultural land tenure, It was not clear that there was a significant correlation relationship between the dependent variable and only two independent variables: the number of family members and community participation.
