Phosphorus is one of the essential macronutrient element not only for rice but also for other plants, it is important for plant metabolism and enzymatic activity during the periods of growth and grain filling. Rice growth, yield and its attributes strongly influenced by phosphorus nutrition. This investigation was conducted to study the performance of different rice genotypes i.e. Sakha105 and Sakha106 (japonica), Giza178 (indica/japonica) and Giza182 (indica) under four phosphorus levels namely 0, 18, 36 and 54 P2O5 ha-1. This study was carried out at Experimental Farm of Rice Research and Training Center during both 2010 and 2011 growing seasons. At harvest, plant height, number of panicles m-2,panicle weight, panicle length, number of filled grains panicle-1, number of unfilled grains panicle-1, 1000 grain weight, grain and straw yield were determined. After harvest, N and P content of rice grain and straw were measured as well as hulling, milling, head rice and amylose percentages were assessed. The obtained results revealed that the rice genotypes were significantly differed in their response to phosphorus application according to genetic background. indica or indica/japonica genotypes responded up to 54 kg P2O5 ha-1 without significant differences with 36 kg P2O5 ha-1 more than japonica type which responded up to 18 kg P2O5 ha-1. Application of phosphorus fertilizer up to 36 kg P2O5 ha-1 improved rice growth traits i.e. plant height and panicle length as well as grain yield and its attributes. Combination of Giza178 with 36 kg P2O5 ha-1 produced the highest grain yield followed by Giza182 with the same levels of phosphorus. Application of phosphorus fertilizer up to 18 kg P2O5 ha-1 gave the maximum grain yield of Sakh105 and Sakha106. Concerning grain quality traits had positive significant effect with increasing phosphorus levels.

EFFECT OF APPLICATION OF RICE STRAW COMPOST AND NPK FERTILIZERS UNDER SOME IRRIGATION REGIMES ON GRAIN YIELD AND WATER PRODUCTIVITY OF EHR1 HYBRID RICE CULTIVAR
I.
El-Refaee
Two field experiments were carried out at the Experimental Farm of Rice Research and Training Center (RRTC), Sakha-Kafr El-Sheikh, Egypt, during 2010 and 2011 summer seasons. The objective of this research was to investigate the effects of NPK fertilizers with rice straw compost on growth and grain yield, as well as water productivity (WP) and nitrogen use efficiency of Egyptian hybrid rice cultivar (EHR1) under different irrigation regimes. A split plot design, with four replicates, was used in all experiments. The main plots were devoted to three irrigation regimes; namely, continuous flooding (CF) and irrigation to 5 – 6 cm depth three (3-) and six (6-) days after disappearance of surface water (DADSW). The sub-plots were occupied by six fertilizer treatments; namely, zero fertilizer (T1), 100% of recommended NPK fertilizer (T2), application of two t/h rice straw compost + 25% NPK (T3), 50% NPK (T4), 75% NPK (T5) and 100% NPK (T6).
The main results indicated that CF and 3-DADSW treatments registered significant and higher values of growth attributes, grain yield and most of its attributes, as well as protein content and N-uptake, compared with 6-DADSW treatment, except for number of days to 50% heading and unfilled grain (%).
Dry matter, LAI, plant height and grain yield and most of its attributes, as well as protein content and N-uptake, were significantly enhanced by the application of 100% NPK, along with rice straw compost at two t/ha (T6), which was at per with T2 (100% NPK) and T5 (75 % NPK + 2 t/h rice straw compost). Under all irrigation regimes, application of NPK fertilizer, either alone or with rice straw compost, recorded higher grain yield and WP than the control treatment.
CF consumed the highest amount of irrigation water, while, application of 3- and 6-DADSW tended to decrease the amount of water used. Furthermore, 3-DADSW recorded the highest WP (0.84 and 0.86 kg/m3) and the minimum grain yield reduction (4.59 and 6.41 %) with water saved about 11.55 and 11.12 % compared to CF in both seasons, respectively.
Generally, under the same experimental conditions, it was concluded to use 3-DADSW irrigation with adding 75% NPK, along with rice straw compost at two t/ha for reasonable grain yield and high WP, as well as it could decrease chemical fertilizer input by 25 % from the present recommended application without decreasing rice grain yield.

These studies were carried out at the Experimental Farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, Egypt, during 2007 and 2008 summer seasons. The purpose was to investigate the effect of irrigation intervals, cut-off irrigation and harvesting times on grain yield and its attributes as well as grain quality characters and water relations of Egyptian hybrid rice cultivar (EHR1). A split split–plot design, with four replicates, was used. The main plots were devoted to three irrigation intervals namely: continuous flooding (CF), irrigation every 6 (6D) and 12 days (12D). The sub-plots were assigned to five times for cut-off irrigation, i.e. cut-off irrigation after complete heading (ACH), 1-, 2-, 3- and 4- weeks after complete heading (WACH). However, the sub-sub plots were consisted of three harvesting times, i.e. harvest rice plants at 10-, 15- and 20- days after cut-off irrigation (DACI).
The main resultsshowed that grain yield and its attributes, as well as milling recovery and protein content, were significantly decreased as irrigation intervals increased from CF up to twelve days, but, unfilled grains (%) and amylose content were increased. Irrigation every six days came in between with insignificant difference with CF in most of previously mentions traits. Delayed cut-off irrigation up to 3- and 4-WACH significantly increased grain yield and most of its attributes, as well as grain quality. However, it reduced amylose content in 2007 and unfilled grains (%) in both seasons, as compared with cut-off irrigation ACH. Harvesting rice plants 10 and 15 DACI recorded the highest number of grains/panicle, panicle weight, 1000 grain weight and grain yield. However, the lowest values of milling recovery and protein content were recorded when plants were harvested at 10 DACI.
Continuous flooding consumed the highest amount of irrigation water, while increasing irrigation intervals up to six and twelve days tended to decrease the amount of water used. Furthermore, 6D treatment recorded the highest water productivity (0.796 and 0.798 kg/m3) and minimum grain yield reduction (4.54 and 3.64 %) with water saved about 8.04 and 7.08 %, compared to CF in both seasons, respectively. Delay cut-off irrigation recorded higher water productivity than early cut-off irrigation after complete heading.
Generally, in case of water shortage, it was concluded to use irrigation every six days and cut-off irrigation 3-WACH with harvest plants 10 DACI for the highest water productivity and grain yield, as well as acceptable grain quality characters, of Egyptian hybrid rice cultivar (EHR1).

The objective of this study was to determine the plant density that result in the best marketable yields and gross crop value per fedan of onion Giza 6 cv. that grown by sets .Sets were grown at the Experimental Farm of the Faculty of Agriculture, Assuit University, Assuit on September 13 and 15 in 2007/2008 and 2008/2009 seasons, respectively. Sets were grown on rows of 3.5 m long and 50 cm wide. Three rows were included each plot. Sets were grown at 4, 6 and 8 cm between plants (175,116 and 87 plants when sets grown on two sides of row and 262,175and131 plants when sets grown on three sides of row). Results showed that , plants gave the smallest bulb diameter when sets were grown at 4 cm space(high density) .The largest space between plants (low density) ,the highest value for both percentage of bolters and doubles were. The highest value of marketable yield was obtained when sets grown at 4 and 6 cm (262 and 175 plants/ row) and on 3 sides per row .Maximum economic returns occurred at higher plant populations. High incidence of double onions was closely related to low onion plant population. Doubles clearly decreased with increased plant density. Wide plant spacing reduced onion bulb yield, but it significantly increased individual bulb weight and bulb diameter.

RESPONSE OF GIZA 90 COTTON CULTIVAR TO FOLIAR APPLICATION OF SOME DROUGHT TOLERANCE INDUCERS UNDER WATER STRESS AND HIGH TEMPERATURE CONDATIONS IN UPPER EGYPT
S.
Hamoda
Two field experiments were carried out in El-Mattana Agric. Res. St., Agric. Res. Cent., Luxor Governorate, Egypt during 2010 and 2011 seasons to study the response of Giza 90 cotton cultivar to the application of some drought tolerance inducers to increase the tolerance of cotton plants to drought under high temperature condations in Upper Egypt. The experimental design was a split plot with four replications. Main plots included two irrigation intervals (15 and 21 days) and sub plot included the foliar application of four drought tolerance i.e CaBoron, Pix, Humex and Methanol) and a control (untreated plants), The obtained results could be summarized as follows: Irrigation every 15 day significantly increased plant height, no. of fruiting branches/plant, no. of days to first flower and first open boll. Prolonging irrigation interval to 21 day significantly decreased no. of open bolls /plant, boll weight, seed index, seed cotton yield/fed., fiber length, uniformity index and fiber strength, but lint % was significantly increased. All drought tolerance inducers significantly increased plant height, number of fruiting branches and open bolls/plant, boll weight, seed index, seed cotton yield /fed., earliness %, fiber length, uniformity index and fiber strength as compared with the untreated plants. In general, plants which were sprayed with methanol gave the highest averages of growth, yield and its components and earliness %, followed by plants which were sprayed with CaBoron, while the Pix sprayed plants came the last in this respect in both seasons. Well watered plants every 15 day showed greater response to Methanol than to any other drought tolerance inducer, while the plants irrigated every 21 day and treated with pix gave the lowest average in this respect. The interaction between studied factors had a significant effect on fiber strength in both seasons and upper half mean length in the first season only. Finally it could be concluded from this study that the CaBoron, Humex, Pix and Methanol applications to plants under normal and water stress conditions could induce drought tolerance of cotton plants and in turn improved plant growth, fruiting and yield particularly under water stress and high temperature conditions.

M.
Emara
Two field experiments were carried out in Sakha Agric. Res. Sta., Kafr El-Sheikh Governorate, Egypt during two growing seasons (2007 and 2008) using the Egyptian cotton cultivar Giza 86 (G. barbadense, L.), to study the response of cotton growth and productivity to application of potassium and zinc under two planting dates. The experimental design was split-plot with four replications. The main-plots were assigned to two planting dates, i.e., normal planting date on March 30th and late planting date on April 30th. The sub-plots included six potassium and zinc fertilization treatments i.e., two soil application levels (24 and 48 kg K2O/fed.) alone or with the foliar application of zinc at the level of 0.5 g Zn SO4/liter. Potassium was also tried as foliar application at the level of 5 kg K2SO4/fed. alone or with the abovementioned level of zinc. Soil added potassium was applied at thinning, while foliar added one was partly sprayed at the beginning of flowering and two weeks later. Zinc was sprayed once at beginning of flowering. The results indicated that sowing date gave significant effects on all growth parameters; no. of open bolls/plant, boll weight, no. of plants/fed. at harvest, seed index and seed cotton yield/fed., upper half mean length, micronaire reading, reflectance and yellowness in favour of early planting. Sowing date did not exhibit any significant on lint %, uniformity index, fiber strength and fiber elongation % in both seasons. Foliar application of potassium along with the foliar application of zinc gave a significant increase in plant height at harvest, no. of nodes/plant, no. of sympodia/plant, no. of open bolls/plant, boll weight, seed index and seed cotton yield (ken./fed.) as compared with the other fertilization treatments. The efficiency use of heat units by cotton plants increased in favour of normal sowing rather than in late sowings. The foliar application of potassium and zinc treatments did not exhibit any significant effect on all fiber quality traits in both seasons. It could be concluded that the foliar application of 5 Kg K2SO4/fed. sprayed partly twice + foliar application of 0.5 g ZnSO4/L once at beginning of flowering stage could be recommended to increase the yield and its components under normal or late sowing dates., for Giza 86 variety, under Sakha region condition at Kafr El-Sheikh Governorate.

Two field experiments were conducted at the Experimental Farm of Water Requirements Research Station, Kafrelsheikh Governorate, North Delta, Water Management Research Institute, National Water Research Centre, Egypt,during 2010 and 2011 seasons, to study the effect of mineral and organic nitrogen fertilizers on rice productivity under traditional transplanting and transplanting in bottom of beds methods and so on water saving and its use effeciency under the conditions of Kafrelsheikh Governorate for rice cultivar Sakha 105. Fertilizer treatments were as following (160 kg N/ha, 120 kg N/+ 5 tons compost/ ha and 80 kg N + 5 tons compost/ ha). Treatments were arranged in split plot design with four replicates. The main plots included the two planting methods, while, the three fertilizer treatments were allocated at the sub plots. The obtained results could be summarized as follows:
The results reveal that the method of planting in bottom of beds led to significantly increased in dry weight at heading, 1000 grain weight, grain yield and harvest index in both seasons as well as number of grains/panicle in the second season compared with the method of traditional transplanting, which recorded a highly significant values in plant height, number of panicles/hill in both seasons and straw yield in the second season.
Data show that planting in bottom of beds led to significant increase in water use efficiency and achieved water saving of 4798 and 4788 m3/ha ( 2016 and 2012 m3/fed.) in the first and second seasons, respectively as compared with traditional transplanting method.
The obtained results show that application of mineral nitrogen 120 kg N in combined with 5 tons compost/ha significantly recorded the highest values of plant height number of panicles/hill, number of grains/panicle, 1000 grain weight,grain and straw yields and harvest index in both seasons as well as dry weight only in the first season .
The treatment of 160 kg N/ha didn't significantly differed with the treatment of 120 kg N + 5 tons compost/ha in 1000 grain weight in the first season, grain yield in the second season and harvest index in both seasons.
From the obtained results under these conditions of this study, it could be concluded that planting rice in bottom of beds saved water in average of 4793 m3/ha and increased water use efficiency as compared with traditional transplanting. Also, application of 5 tons compost plus 120 kg N/ha gave the highest productivity of rice cultivar Sakha 105 Kafrelsheikh.

Naeem
Field experiments were conducted at Rice Research and Training Center, Sakha, Kafrelseikh Governorate, Egypt during two summer seasons 2010 and 2011 to study the influence of integration between compost and urea fertilizer on yield and its components of Sakha 105 rice cultivar as well as nitrogen uptake in rice grains and soil organic matter percentage. The treatments were (0, 5 ton compost/ ha, 165 kg N/ha, 5 ton compost + 55 kg N/ha and 5 ton compost + 110 kg N/ha).
The results revealed that compost and mineral nitrogen (urea) alone or in combination recorded increasing significant values in number of panicles/hill, number of filled grain/panicle, 1000 grain weight,grain and straw yields, nitrogen uptake and soil organic matter percentage compared with the control treatment (without fertilization) except the number of unfilled grain/panicle which recorded significantly decrease.
The results, also, showed that compost application at rate of 5 tons plus 110 kg N/ha gave the highest values of number of panicle/hill, number of filled grains/panicle, 1000 grain weight, grain yield, straw yield, nitrogen uptake in grains and soil organic matter percentage in both seasons.
The control treatments (without fertilization) recorded the lowest values in all traits as well as yield components, grain yield, straw yield, nitrogen uptake in grain and soil organic matter percentage except the number of unfilled grain/panicle which recorded the highest values in both seasons.
In both seasons the following treatments of 165 kg N/ha, 5 ton compost plus 55 kg N/ha and 5 ton compost plus 110 kg N/ha didn’t significantly differ in its effect on the number of filled grains/panicle.
In both compost application at a rate f 5 tons alone or in combination with 110 kg N/ha gave the same 1000 grain weight without significantly differences with 165 Kg N/ha treatment in the second seasons.
The percentage of soil organic matter was increased with addition of compost either alone or with different levels of nitrogen which did not significantly differed in its effect on the percentage of soil organic matter.
From the results under the conditions of this study, it could be concluded that application of 5 tons compost plus 110 kg N/ha produced the highest grain and straw yields and is recommended as an economic treatment for increasing grain yield of rice.

This study was carried out in NationalResearchCenter in Dokki, Giza, Egypt in collaboration with Botany department, Faculty of Science, MansouraUniversity during 2007-2009 seasons. This study first, aims to find Egyptian wild narcissus bulbs for scientific records and genetic fingerprinting as an Egyptian species. Unfortunately the bulbs almost disappeared from about two decades under the pressure of tourism and ordinary cultivation in north coast of the country. Hopeless looking for any evidence it may be still found, but our search in many areas in Egypt fails to find any bulb. And so, the study continues based on another two species of narcissus foreign one Narcissus tazetta cultivated for many years in Egypt and a commercial variety from flowers producer. The other aim of our study was to carry out phytochemical screening to estimate the natural components of Narcissus tazetta plants and data showed that many constituents were found in the form of alkaloids including flavonoids, tannins, sterols and triperpenes. Finally, molecular studies using RAPD-PCR were carried out to fingerprint the two species of narcissus using ten 10-mer primers, indicating that unique fingerprinting bands as produced by primers number 1, 2 and 3 could clearly discriminate between the two species for example, fragments with approximately molecular size of 2764 bp, 2344 bp, 1114 bp, 978 bp and 792 bp were detected in Narcissus tazetta profile while, fragments with approximately molecular size of 1787 bp, 1996 bp, 1592 bp and 583 bp were detected in commercial narcissus profile.

The effect of some organic soil amendments such as cattle, poultry and sheep manures and four insecticides nudrin 90%, selecron 72%, tracer 24% and vertmik 1.8% and their interaction on sugar beet productivity and the infestation rate of beet fly, P. mixta were carried out at Damanhour and Nubariya regions under field conditions.
The results raveled that population density of P. mixta, root yield, top yield, sugar yield and quality parameters were significantly affected by all organic manures and insecticides treatments. Generally, the highest accumulative larvae of P. mixta recorded with poultry manure followed by cattle manure and sheep manure in Damanhour and Nubariya regions. Also, in two locations poultry manure gave remarkable results in suppression in root, top and sugar yields as well as sucrose and purity% compared with cattle and sheep manures. All tested insecticides in the two locations significantly reduced the population density of beet fly, P. mixta on sugar beet plants in comparison with the cheek treatment. Sugar beet plants sprayed by selecron 72% the reduction% of P. mixta population increased with the time elapsed treatment. Selecron 72% was the most effective against P. mixta followed by tracer 24%, vertmic1.8% and nudrin 90%. Also selecron 72% was ranked the first in root and top yield, however, sugar yields gained the highest value by tracer treatment. Top, root and sugar yields, T.S.S.% and purity% were significantly affected by the interaction between tested organic manure, and insecticides. The highest top, root and sugar yields were obtained with (cattle manure x selecron 72%), (poultry manure x tracer 24%) and (cattle manure x tracer 24%) treatments, respectively. However the highest values of T.S.S. and purity% were obtained with (poultry manure x tracer 24%) treatment.

Two field experiments were carried out during the two successive winter seasons of 2008/2009 and 2009/2010 at El-Gemmeiza Agricultural Research Station, Gharbeya Governorate, toevaluatethe effect of chicken manure levels, biofertilizers, some foliar application treatments and their interactions on plant growth and leaf pigments of garlic (Allium sativum L.) Sids 40 clone.
The obtained results showed that the highest values of plant height, number of leaves/ plant, leaf area , fresh and dry weights/plant, neck and bulb diameters at 105 and 135 days after planting in both seasons and dry weight of bulb at 135 days after planting, chlorophyll a, b and total (a+b) as well as carotenoides were recorded with the highest nitrogen rate (120 kg N/fed.) in the form of chicken manure at 4.137 ton/fed. or mineral N ( control). Inoculation of garlic cloves with biofertilizers caused a high significant effect on all plant growth characters and leaf pigments as compared to uninoculated plants. Spraying garlic plants with yeast extract significantly increased plant height, number of leaves/ plant, fresh and dry weights/ plant, neck and bulb diameter as well as dry weight of bulb at 135 days after planting, chlorophyll a, b and total (a+b) as well as carotenoides in both season followed with spraying seaweed extract treatment.
The best results of vegetative parameters were obtained with application of nitrogen fertilizer at 120 kg N/fed. of chicken manure at rate of 4.137 ton/fed. or mineral nitrogen with biofertilizers and foliar application of yeast extract. Therefore, this treatment could be recommended for improving garlic vegetative growth parameters under similar conditions to this study.
