Phosphorus Efficiency of Different Maize (Zea mays, L.) Genotypes Grown on Calcereous Soil
Abou El Seoud,

H. M.
This research aimed to study P efficiency of ten maize genotypes (zea mays, L.) under two levels of P in calcareous soil and to quantify the contribution of root growth in P uptake. Plants were grown in potted soil with two levels of available P in soil 40(low P) and 270 (high P) mg P/ kg soil in glasshouse with five replicates in randomized complete block design. The maize genotypes were harvested 4 weeks after transplanting. All plants increased significantly with increasing P level, except code 1, code 3, code 7 and code 8 (single hagen 10, 15, Bshaier 13 and Pioneer 3062 respectively), there was no significant difference between shoot dry matter at low and high P level. Maize genotypes (code1, code 3, code 7, and code 8) attained more than 80% of its maximum yield already at the lower level of available P. In contrast, at low level of available P, maize genotypes code 5 and code 9 (single hagen 123 and 151 respectively) attained only 21.9% and 14.7% respectively of their highest yield. This signified that maize genotypes (code1, code 3, code 7, and code 8) had high P efficiency, whilst maize genotypes (code 5 and code 9) had low P efficiency. Maize genotypes code1, code 3, code 7 and code 8 had longer roots in limited P supply followed by code 2, code 4 and code 6 (single hagen 12, 122 and 129 respectively), and the shorter roots observed in maize genotypes code 5, code 9, and code 10 (single hagen 155). The adaptation of maize genotypes to low level of soil P is closely related to better developed root system and the increase in root length under P stress may be one of the possible mechanisms of P efficiency in maize. At low P level, code 1 and code 7 were the highest P uptake per plant. In contrast, code 5 and code 9 were the lowest maize P uptake. In conclusion, the results of this study suggested that root growth system would be a suitable plant parameter for selecting P efficient maize genotypes especially under limited P supply.

An experiment was conducted in a greenhouse to evaluate the biological performance of some agrochemical and biological agents against root-knot nematode on tomatoes planted in clay soil. The antagonistic bacterium Pseudomonas flouroscence was proved to be the most effective tool suppressing the infection of root-knot nematodes on tomatoes during the period of inspections. The mean of population reduction of P. flouroscence was (79.4%), followed by the mixture of antagonistic fungus and bacterium Trichoderma harazianum plus Pseudomonas flouroscence (73.0%), then fosthiazate (60.3%), while the least effective one was abamectin (22.5%). On the other hand, abamectin applied as soil drench gave the highest reduction percentage (81.6 % of root galls / 5g roots) followed by oxamyl (62.4%), then fosthiazate (61.5%). Carbofuran recorded the least reduction percentage of 33.1 % of root galls /5g roots. Meanwhile, abamectin gave the highest reduction percentage on egg masses / 5g roots (79.1 % ), followed by oxamyl and P. flouroscence giving 61.4 and 39.9 reduction percentages. The least effective treatment was Trichoderma harazianum which increased the egg masses by 18.8 %. Some treatments showed an indirect effect on the root and shoot system length and weight. The antagonistic fungus Trichoderma harazianum was the superior treatment which increase the root system length by 39.1 %, whilst abamectin didn't show any increase. Trichoderma harazianum as well as fosthiazate proved to be the most effective treatment on the root system fresh weight as they gave 86.8 and 85.5% increase, respectively. Abamectin was the least effective treatment giving 5.3% increase. On the other hand, T. harazianum was effective and gave the highest increase percentage of shoot system length followed by oxamyl (54.9 and 46.8%, respectively). Meanwhile, the same trend was obtained in case of shoot system weight giving increases of 87.8 and 81.9%, respectively. Abamectin treatment was the least efficient on its effecton both root system length and weight increase.

The experiment was investigated to study evaluate the seed germination of Leucaena leucocephala (Lam.) de Wit. under salinity, temperature, light and their interaction on the rate and final percentage of germination. The experiment was carried out in plant physiology laboratory at College of Science, King Saud University, Riyadh, Saudi Arabia. The collected seeds of Leucaena was treated with boiling water for 3 minutes then left to germinate in Petri dishes in growth chamber under the investigated treatments. Seven concentrations of sodium chloride solution had EC of (0, 50, 100, 300, 400, 500 and 600 mM) were applied to seeds as irrigation water and exposed to three temperature degree (20, 30 and 40 oC). Seeds untreated with NaCl germinated well in a wide range of temperatures and in both full light and complete dark. Seed germination decreased significantly with the increase in both NaCl concentration and temperature. Optimal germination percentage occurred at 30 oC. The inhibitory effect of high salinity on final germination percentage was greater at 40 oC than at 20 and 30 oC. However, germination rate was significantly greater at 40 oC than at 20 and 30 oC in lower salinity and the reverse was true at higher salinity. Germination in light was significantly greater than in the dark at lower salinity levels and high temperature.

Field experiment was conducted in seasons 2007 and 2008 on Indian ber trees (Zizyphus mauritiana Lamk) to evaluate the effect of fertilizing Toffahy and Balahy varieties with micronutrients (Cu, Zn, Mn and Fe) on some vegetative and fruits characters and on leaves and fruits mineral content. Two varieties (Toffahy and Balahy), four treatments of micronutrients combinations and two methods of application (soil and foliar application) distributed randomly in a randomized block design with three replicates were used in a farm west of Alexandria, Nubaria sector. The results showed that, length of secondary shoots, total leaf chlorophyll and leaf area increased by increasing rates of application and that soil application was more pronounced than foliar one. At the same time, the dry weight of leaves did not response to either soil or foliar application of micronutrients. Moreover, Toffahy variety responded to micronutrients addition more than Balahy one. Fruit characters as height, diameter, weight, size and firmness responded significantly to micronutrients addition, while weight of seeds did not show any response to those additions. Total soluble solids (%TSS) and acidity in the first season showed significant response to micronutrients addition, while vitamin C was contrary to them. DTPA- extractable Mn, Zn and Fe responded significantly to soil application while Cu showed no response. At the same time, Cu responded similar to Zn and Fe in leaves while Mn did not respond. Once again, Cu had not responded in fruits while the three other elements showed highly response to micronutrient additions. In all cases, soil applied micronutrients increased their concentration in leaves and fruits more than foliar application except Cu.

Research was conducted at the Nubaria Horticultural Research Station, El-Bohira Governorate in Egypt’s calcareous soil to determine the effect of humic acid amendments and flood irrigation scheduling on the development and growth of Prunus domestica L. (Kelsy plum). The research was conducted over a four year period beginning in 2005 when the plum fruit trees had developed for 2 years having budded on a Mariana rootstock. Tests were conducted during 2006- 2009 growing seasons. The main and interacting effects of flood irrigation frequency and humic acid amendments were tested using a split-plot design experimental set-up. Kelsey plum was planted at a spacing of 4 x 5 m under a flood irrigation system in calcareous soils. The trees were irrigated under three regimes, which were: 5-day (I1), 10-day (I2) and 15-day (I3) interval. The humic acid treatments (thereafter referred to as HA) included: humic acid soil application around tree’s trunk (T1), foliar application (T2), soil and foliar application (T3) and a control (T4) whereby no humic acid treatment was made. HA treatments were applied on the months of April, May, June and July during each of the years (2006-2009). During 2006 and 2007 vegetative growth measurements and leaf mineral contents were measured. In 2008 and 2009 when the plum trees had attained maturation and had reached their reproductive stage, the fruit quality and yield were determined. Each of the humic acid additions in either soil or foliar application method increased the physical attributes (vegetative) of the trees during the first and second seasons of growth relative to the control. The combined foliar and soil applications of humic acid (T3) increased tree height and Trunk Cross-sectional Area (TCA); shoot number, length and diameter during 2006 and 2007 seasons compared to all other treatments. The largest combined effect of irrigation and humic acid treatments during the vegetative seasons (2006 and 2007)on the plum trees was observed for the T3 I2 treatment, followed by the T3 I1 and T1 I2 in that order. The vegetative growth parameters highlighted the importance of humic acid and its usefulness in increasing water use efficiency for the 10-day irrigation interval as compared to the 5-day interval. Foliar and soil humic acid treatment significantly induced high leaf contents of both macro- and micro- minerals (N, P, K, Fe, Mn and Zn). The soil mode of application T1 was inferior to the foliar mode of humic acid application (T2) during the growing seasons of 2006 and 2007. In the two studied years 2008 and 2009, the highest yield with good fruit quality was obtained from trees under T3, so it recommended.

The present work was carried out during 2008 and 2009 years to investigate the possibility of utilization of natural raw mineral mixture (NRMM) and magnetite raw (magnetic iron) as a substitute for chemical fertilizers for feeding "Le Conte" pear trees planted in calcareous soil.The trial was conducted in Nubaria area El –Bohira Governorate.Trees were 7 years old, budded on communis rootstock and spaced at 4x5 m.apart. Eight treatments beside the control were used [4 NRMM treatments +4NPK treatments], all treatments, except the control were received magnetite raw as follows: 250, 500, 750, and1000gm /tree. The comparison among NRMM and NPK treatments cleared the following points: § NPK treatments significantly increased shoot diameter in both studied years and shoot length in the first year only, while the differences for shoot number and leaf area were not statistically significant NPK treatments also, significantly enhanced leaf total chlorophyll (SPAD) in 2009. § NPK treatments induced high significant leaf N% in both studied seasons and leaf K% and P% in 2008 only. § NRMM treatments significantly increased leaf Mn and Zn in both growing seasons, while NPK treatments significantly enhanced leaf Fe in the two years. § NPK treatments induced significant high fruit yield/tree in the two seasons; meanwhile the differences between NPK and NRMM treatments for fruit quality were not statistically significant. § Increasing the applied rate of magnetite raw/tree significantly increased vegetative growth, leaf total chlorophyll, leaf mineral composition, yield and fruit quality. § Fruit analysis revealed that the heavy metals (cobalt, nickel and lead) were in the permissible limits. § The cost of the NPK treatments was nearly twice the cost of NRMM treatments. Using natural raw mineral mixture and magnetite raw as a substitute for chemical fertilizers for feeding "Le Conte" pear trees were reasonable but it needs more studies.

This present work was carried out to investigate the effect of spraying Dormex (at 3%) at the end of Jan. and Sitofex at (5, 10, 15 and 20ppm) at full bloom and fruit set alone or combined with each other on time of bud burst, fruit set %, yield/tree and fruit quality of "Costata" kaki cultivar, planted in El–khadra area El-Bohira Governorate. The results can be summarized in the following points: 1- In both years of study, the date of bud burst of trees sprayed with Dormex (at 3%) was early (28//2/2007 and27/2/2008) than that of control trees (19/3/2007 and 21/3/2008), respectively. 2- Insignificant differences were detected between the two tested dates of spraying Sitofex at (5, 10,15and 20ppm) for all the studied parameters. 3- The best effects were obtained from trees sprayed with 20 ppm sitofex + dormex at 3% treatment, so it is recommended to obtain high fruit set percentage, fruit yield and to improve physical fruit properties i.e: weight size,length,diameter and firmness. On the other side,this treatment induced low TSS% ,high acidity% and tannins%, that means delaying the date of maturation which has great importance for postponing harvest date and increasing shelf-life period and storage ability.

The aim of this investigation was to study the effects of two different cultivars of sweet corn (Zea mays var. rugusa, L.), three different plant spacings and three different mineral NPK fertilizers levels, and their interactions on vegetative growth, yield and yield components, and kernels quality characters. To achieve this aim, two field experiments were conducted at the Agricultural Research Experiment Station, King Abdulaziz University, Hada-Alsham,Saudi Arabia, during 2006 and 2007 summer seasons. The obtained results indicated generally that the differences among the means values of each studied factor, first-and second - order interactions for the vegetative growth, yield and its components, and kernels quality characters, were significant; but, with different magnitudes, during the two summer seasons. Also, the results indicated generally that the cultivar "Merit" was the best for the most studied vegetative growth, and yield and its components characters, whereas, the cultivar "Challenger" was the favourable cultivar for the kernel quality parameters. The results indicated that increasing either plant spacings or the mineral NPK fertilizers was associated with corresponding increments in most of the studied characters of sweet corn, during both summer seasons. Generally, the results of the first-and the second-order interactions effects on all the studied characters, showed that one of the used cultivars with either widest spacing between plants or/ and the highest level of mineral NPK fertilizers gave the highest means values of all the studied characters, during both growing seasons.

Two winter field experiments were carried out at the Agricultural Research Experiment Station, King Abdulaziz University, Hada-Alsham, Saudi Arabia, during the two years of 2007 and 2008, in order to assess the response of the two potato cultivars Diamont and Nicola to two rates of chicken manure (15 and 30 m3 ha.-1) as well as control treatment (without addition), three levels of mineral NPK fertilizer (200-100-100, 300-150-150 and 400-200-200 kg N-P2O5-K2O ha.-1) in addition to control (without application), and their combinations on vegetative growth, yield and its components, and chemical compositions characters of potato. The obtained results indicated generally that the comparisons among the mean values of the studied vegetative growth, yield and chemical composition for each factor (main effects) appeared to be significant in most cases, during the two growing seasons. The results illustrated also that the cultivar Diamont gave the highest mean values of all studied characters, with few exceptions, in both seasons. An application of either organic manure at the rate of 15m3. ha.-1 or mineral NPK at the level of 300-150-150 kg.ha.-1 gave significantly the highest mean values of most studied vegetative growth, yield and its components and chemical compositions, during the two years. The results concerning the first-order interaction indicated that the combination between cultivar Diamont and either of organic manure at the rate of 15m3 ha.-1 or mineral NPK fertilizer at the rate of 300-150-150 kg ha.-1, and the interaction effects between the treatment combination of organic manure and mineral NPK fertilizer at such rates, resulted in the highest significant mean values of the vegetative growth characters, most of the studied yield components and some of chemical compositions, in the two seasons. The obtained results indicated also that the treatment combination of cultivar Diamont with organic manure at the rate of 15 m3 ha.-1 plus mineral NPK fertilizer at the level of 300-150-150 kg N-P2O5-K2O ha.-1, gave the best second-order interaction treatment for most studied vegetative growth, all potato yield and its component characters, and some of the chemical composition parameters, during the two growing seasons of the years 2007 and 2008.
