YIELD AND YIELD COMPONENTS OF HYBRID ONE RICE CULTIVAR AS AFFECTED BY IRRIGATION INTERVALS, FERTILIZATION COMBINATIONS AND THEIR INTERACTION
Rice is a very important cereal in Egypt and allover the world. In Egypt, it is a crucial food crop because of shortage in wheat production. Because of water shortage, in Egypt, trials were conducted to find out the effect of water deficit combined with fertilizer combinations on yield and yield components of hybrid one rice cultivar. Two field experiments were carried out at the Experimental Farm of Rice Research and TrainingCenter, Sakha, Kafr El-Sheikh, Egypt, during 2011 and 2012, rice growing seasons. A split plot design with three replications was used. The main plots were devoted to four irrigation intervals; 3, 6, 9 and 12 days. The sub plots were occupied by seven fertilizer combinations; control (without fertilizer), recommended 100% NPK, 2.10 t/fed. compost, 25 , 50 , 75 , 100 % NPK+ 2.10 t/fed. compost.
All agricultural practices were applied as recommended for rice Hybrid one cultivar. The main results revealed that yield and its components were significantly affected by irrigation intervals. Number of panicles/m² , panicle weight, 1000-grain weight, grain yield (t/fed) and harvest index significantly decreased as irrigation intervals prolonged up to 12 days in both seasons. On the other hand, no significant differences were found between 3-day and 6- day irrigation intervals on yield and yield attributes. The fertilizer combinations had highly significant effect on yield and yield attributes of hybrid one rice cultivar. The highest values of Leaf area index, dry matter weight, plant height, number of panicles/m², panicle weight, 1000-grain weight, grain yield (t/fed) and harvest index were recorded in plots fertilized with full recommended dose of nitrogen (69 kg), phosphorus (15.50 kg) and potassium (24 kg) followed by these fertilized with full dose of NPK without any compost or 75 % recommended dose of NPK + compost. The interaction between irrigation every three days and fertilization with 100 % NPK + compost or 75 % NPK + compost gave the highest values of number of panicles/m², panicle weight,1000-grain weight, grain yield and harvest index.

IMPROVING CARNATION RESISTANCE TO ROOT-KNOT NEMATODE INFECTION UNDER GREENHOUSE CONDITIONS
The current research was conducted at Tissue Culture laboratory of Vegetables and Ornamental Dept., and greenhouse of Nematology Research Unit, Agricultural Zoology Dept., Faculty of Agriculture, Mansoura Univ., Egypt. The effect of certain components i.e. L-glutamic acid, ascorbic acid, yeast extract and phenylalanine introduced singly at 1 g/ L added to MS medium used for the growth of the carnation seeds, obtained from France before transplanting into plastic pots filled with sterilized loamy sandy soil on Meloidogyne incognita infection was evaluated under greenhouse conditions at 22±5°C. Results indicate that among tested treatments, application of L-glutamic acid gave the highest reduction percentage in M. incognita root galls by 57.14% while ascorbic acid ranked first in respect to egg-masses with value of 65.25%. However, Yeast extract exceeded other tested components in percentage increase of the whole plant fresh and shoot dry weights of the infected carnation seedlings and uninfected plants as well with values of 99.09 and 53.33%; and 55.96 and 211.8%, respectively. Thus, it could be concluded that yeast extract or L-glutamic acid applied in MS medium considered the best treatments in improving growth of carnation plants, increasing growth and suppressing M. incognita development and reproduction under greenhouse conditions.

ESTIMATION OF SOME GENETICAL PARAMETERS AND THEIR IMPLICATION ON YIELD IMPROVEMENT IN MAIZE USING TWO SELECTION METHODS
Prediction is of great importance for the reasoning on the feasibility of completion the selection process. In this study, we compared the expected effectiveness of two intrapopulation selection methods of S1 progeny and half-sib progeny via Design I mating scheme in improving the yield of Nubaria yellow maize population (NYP). For fairer comparison, we unified germplasm used in the two methods by using S1 seeds supposed to be kept for recombination in half-sib family selection as a germplasm of S1 family selection. This permitted studying the outbred and inbred progeny for the same parent. Our germplasm involved 81 S1 families, and 324 full-sib families forming 81 half-sib families. Evaluation were done at Gemmeiza and Sids locations representing two different environments of Middle Delta and Upper Egypt regions, respectively. By looking over the performance of couples of families for parents, there was no clear relation between performance of inbred and outbred families. Design I analysis showed predominance of additive genetic variance component in all studied traits in both environments, whereas dominance variance had negative values in most cases. Influence of environment was obvious on changing genetic variance from location to another. Heritability values were high for both progenies for most studied traits at both locations. Genetic gains were conflicting among different studied traits. The preference was for S1 family selection for yield components (ear diameter, ear length and kernels number/ear), except rows number/ ear where the advantage was for half-sib family selection adding to plant height, ear height and ear position traits. Both methods were almost equal for 50 % silking and still S1 family selection has the bigger expected gain for grain yield trait.

COMPARATIVE STUDIES BETWEEN TWO SELECTION METHODS FOR IMPROVEMENT OF YELLOW MAIZE POPULATION YIELD
Recurrent selection is the most common mean for indirectly enhancing inbred lines performance by enhancing the performance of their sources of populations. We compared the effectiveness of two intrapopulation selection methods of S1 progeny and half-sib progeny viaDesign I mating scheme in improving the yield of Nubaria yellow maize population (NYP) (C0). For fairer comparison, we unified germplasm used in the two methods by using S1 seeds supposed to be kept for recombination in half-sib family selection as a germplasm of S1 family selection. This permitted studying the outbred and inbred progeny for the same parent providing the prospect for combined selection on which selection unit is the parent family (both half-sib and S1 families for the same parent). In recombination season, at harvest, S1 topcrosses of each improved population were separated to examine the general combining ability of each recombined S1. The three resulting improved populations via their respective S1 topcrosses were under evaluation with the original and the check populations. Significant differences were detected among S1 topcrosses for grain yield trait. Actual gain for grain yield (3.9 and 3.7 ard/fad for S1 and H.S.family selection methods, respectively) were apparently one-half the predicted gain. Grain yield has improved significantly through this cycle with an increase up to 32 % than the original population. Theimproved population by combined selection was the highest yielding followed by the improved by S1 family selection then the improved by half-sib family selection with non significant differences among the three improved populations.
We recommend with using the improved population resulting from the combined selection as a sub-population and combining the three improved populations seeds without those of S1 topcrosses with low-performance in one population used for isolation and as a material for the coming improving cycles of recurrent selection.

EVALUATION OF SOME DATE PALM CULTIVARS GROWN UNDER TOSHKY CONDITIONS
This study was carried out during two successive seasons of 2011 and 2012 on some date palm cultivars grown under the conditions of Toshky region. Seven date palm cultivars were evaluated and classified to two groups: dry date palm cultivars (Sakkoty, Bartamoda, Gondela, Malkaby and Balady [Maghal]) and soft date palm cultivars (Barhee and Sokkary). Sakkoty and Bartamoda (dry date palm cultivars) and Barhee (soft date palm cultivar) gave the highest number of leaves per palm/year, while Malakaby (dry date palm cultivar) and Sokkary (soft date palm cultivar) gave the highest number of leaflet per leaf in both seasons. Bartamoda (dry date plm cultivar) and Sokkary (soft date palm cultivar) gave the highest yield, fruit weight and flush weight in the two seasons. Balady [Maghal] (dry date palm cultivar) and Barhee (soft date palm cultivar) showed higher moisture content (%) in both seasons. Bartamoda (dry date palm cultivar) and Sokkary (soft date palm cultivar) gave the highest soluble solids content and total sugars (%) while Gondela (dry date palm cultivar) and Sokkary (soft date palm cultivar) gave the highest reducing sugars (%) in the two seasons. Evaluation study revaluated that Sakkoty and Bartamoda were the best dry date palm cultivars. Wherever, Sokkary cultivar was the best soft date palm cultivars growing under Toshky conditions.

IMPROVING SAFFLOWER (Carthamus tinctorius L.) GROWTH AND BIOLOGICAL ACTIVITIES UNDER SALINE WATER IRRIGATION BY USING IRON AND ZINC FOLIAR APPLICATIONS
The present study aimed to evaluate growth and biological activities ofSafflower Carthamus tinctorius L. treated with Iron and Zinc foliar applicationunder Irrigation with saline water at Wadi El-Natrown, El-Behera Governate Egypt during two winter seasons; 2011/ 2012 and 2012/ 2013. It aimed to find out the individual and combination effects of foliar application of Iron (Fe) and Zinc (Zn) on vegetative growth, reproductive and yield characters, in addition to some chemical constituents of Safflower plants. All the vegetative growth characters; plant height, number of primary and secondary branches were significantly affected by the foliar application. Foliar application by Zn at 0.6% significantly promoted the plant height followed by application by the combination between Fe: Zn at 0.3:0.6%. The later treatment gave the greatest number of primary and secondary branches followed that of Zn at 0.6% where there was no significant difference between the two treatments. The highest number of inflorescences and seed yield per plant or plot or fadd was obtained by using the combination between Fe : Zn at a ratio of 0.3:0.6% or by Zn only at 0.6%. The percentage of Zinc, Iron, lipid, protein and pigments in addition to biological activity in different plant treatment were determined. All of chemical parameters were significantly affected by Zn, Fe foliar application at different concentration.

PERFORMANCE OF SOME RICE GENOTYPES UNDER BOTH SALINITY AND WATER STRESS CONDITIONS IN EGYPT
The present investigation was carried out at Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, Egypt, during summer seasons 2011 and 2012 as a preliminary study to breed for Egyptian super rice varieties. The objectives of the present study ware aimed to comprise 10 local and exotic rice cultivars to be tested under the two stresses, salinity and water stress in order to identify one or more genotypes could be grown under both conditions and/or to be utilized as a donor in the program to establish an Egyptian super rice varieties. Results clearly showed significant and highly significant differences between examined genotypes regarding all studied characters as affected by the different salinity levels and water stress conditions in the two seasons. Under the two conditions all of the investigated characters were decreased significantly by increasing salinity levels except sterility % increased by increasing salinity levels. The results also revealed that GZ1368 –S-5-4 followed by Giza 179 and Giza 178 were found to be the highest tolerant rice genotypes to salinity levels beside to its significant degree of drought tolerance, these genotypes could be nominated to be grown either under salt effected soil or under water stress conditions and/or used as a donor for those types of stresses in any crossing program towards breeding for Egyptian super rice varieties. On the other hand, although, Sakha 102, Sakha 101 and Giza 182 which exhibited high yielding under normal conditions, they were found to be highly sensitive rice genotypes under both salinity and water stress conditions.
The results showed that also PCV (phenotypic coefficient of variance) in general was higher than GCV (genotypic coefficient of variation) for various characters. However the difference between GCV and PCV was low for most of the characters studied. This indicates less degree of environmental influence on manifestation of these characters. High heritability coupled with high genetic advance were recorded for number of filled grains per panicle, number of panicles/ plant and grain yield/ plant indicated the major role of additive gene action in the inheritance of these characters and these characters could be improved by selection in early segregating generations. Thus, these characters may serve as an effective selection parameter during breeding program for crop improvement.

EFFECT OF SPLIT APPLICATION OF NITROGEN FERTILIZER ON MORPHO-PHYSIOLOGICAL ATTRIBUTES AND GRAIN YIELD OF BROADCAST SEEDED EGYPTIAN HYBRID RICE (Ι)
An experiment was carried out at the Experimental Farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, Egypt, during 2011 and 2012 seasons. The experiment was laid out in a split plot design with four replications. The main plots were devoted to the nitrogen level 220kg N/ha in form of urea (46.5% N). The sub-plots were allocated to the six times of nitrogen application to assess the effect of six nitrogen application treatments, viz., T_1: (2⁄(3 ) as B ( basal ) + 1⁄3 at PI ( panicle initiation)), T_2: (1⁄3 as B + 1⁄3 at MT (mid-tillering) + 1⁄3 at PI.)), T_3:(1⁄2 as B + 1⁄4 at MT + 1⁄4 at PI.)), T_4:(1⁄4 as B + 1⁄4 at MT + 1⁄4 at PI + 1⁄4 at BT (booting)), T_5:(1⁄4 as B + 1⁄4 at MT + 1⁄4 at BT + 1⁄4 at CH (complete heading)), and T_6:(1⁄4 as B + 1⁄4 at MT + 1⁄4 at PI + 1⁄4 at F ( flowering)) on morpho-physiological attributes and grain yield of Egyptian hybrid rice (1) under broadcast seeded-rice. The results revealed that nitrogen levels caused significant increases in all morpho-physiological attributes and grain yield of Egyptian hybrid rice (1), except for number of primary branches/panicle, number of panicle/m², panicle weight and 1000-grain weight in both seasons. Leaf area index and dry matter production at flowering were significantly increased in first and second seasons, respectively, Increasing N-level up to 220kg N/ha significantly increased number of unfilled grains/panicle and straw yield t/ha. In addition, application of 165kg N/ha produced the highest values of number of filled grains/panicle, grain yield t/ha and harvest index in both seasons. Moreover, It was observed that the highest estimated values of dry matter production at panicle initiation and straw yield; and the lowest number of panicles/m² were recorded in the first treatment (T_1), without significant differences with the 〖(T〗_(3 )) and 〖(T〗_(5 )) treatments in both seasons. The highest dry matter production at flowering, LAI at flowering, chlorophyll content in flag leaf, days to 50% heading, plant height at harvest, number of primary branches/panicle, panicle weight, heaviest 1000-grain weight, harvest index and grain yield were exhibited in 〖(T〗_(6 )) in both seasons, The interaction between nitrogen levels and time of nitrogen application had significant effect on dry matter production ( g/m²) at panicle initiation, leaf area index at both panicle initiation and at flowering, chlorophyll content in flag leaf and number of tillers/m², number of filled grains/panicle in both seasons and number of unfilled grains/panicle in the second season. From the obtained results, it could be recommended that splitting of N-fertilizer application with the rate of 165 kg/ha in four equal doses i.e. as basal application, mid-tillering, panicle initiation and at the flowering stages were played a remarkable role for achievement of high yield production from Egyptian hybrid (1) rice genotype, when it grown under broadcast seeded rice under normal soil in Egypt.
