EFFECT OF KINETIN AND MINERAL FERTILIZATION ON GROWTH FLOWERING, BULBS PRODUCTIVITY, CHEMICAL COMPOSITIONS AND HISTOLOGICAL FEATURES OF Hippeastrum vittatum PLANT
Two field trials were carried out to study the effect of 16 treatments represented the combination between four concentrations of kinetin (0.0, 20, 40 and 60 ppm.) and four levels (0.0, 2, 4 and 6 g/plant) of mineral fertilization on the growth, flowering, bulb productivity, chemical composition and histological features of Hippeastrum vittatum plant.Results showed that all tested kinetin concentrations statistically improved vegetative growth parameters i.e., plant height, number of leaves, leaves fresh weight and leaves dry weight, flowering growth parameters i.e., flowering start, inflorescence length, flowering stem diameter and inflorescence fresh weight, bulb growth parameters i.e. bulb diameter, fresh and dry weight of bulb, number and diameter of bulblets, chemical composition parameters i.e., N, P, K, total carbohydrates and total chlorophylls contents as well as endogenous phytohormones i.e. cytokinins, gibberellins, auxin (IAA) and abscisic acid (ABA) and histological features of Hippeastrum vittatum leaf with superior to the medium and high rates.
Also, all mineral fertilization levels significantly improved the aforementioned parameters, especially the high levels. Additionally, most the combinations of kinetin concentrations and levels of mineral fertilization improved all the studied parameters, particularly combinations between kinetinat 60 ppm and mineral fertilization at 6 g/plant in both seasons. As for the anatomical studies, several alternations were existed with different applied treatments. Most of the combinations between kinetin concentrations and levels of mineral fertilization gave the highest parameters values in transfer sections of the blade as compared with the control. The most effective treatment was kinetinat 60 ppm combined with mineral fertilization at 6 g/plant.
Conclusively, spraying Hippeastrum vittatum plants with kinetin at 60ppm and mineral fertilization with N:P:K at the ratio of 2:1:2, respectively induced prospective effects on vegetative growth and flowering parameters with higher bulbs productivity.

IRRIGATION REGIME AND POTASSIUM LEVELS EFFECTS ON YIELD OF SOME RICE GENOTYPES, WATER USE EFFICIENCY (WUE) AND ECONOMIC RETURNS
Irrigation intervals and potassium levels were studied using Giza179, GZ7112 and Sakha106 rice genotypes at the experimental Farm of Rice Research and Training Center (RRTC) Sakha, Kafr El-Sheikh, Egypt, during 2012 and 2013 seasons. Four irrigation intervals treatments namely; continuous flooding (W), irrigation every 4 days (4W), irrigation every 8 days (8W) and irrigation every 12 days (12W), as well as five rates of potassium; 0 (K0), 36 (K1), 72 (K2), 108 (K3) and 144 (K4) kg K2O/ha were used. The field experiments were laid out in a split-spit design with four replications. The irrigation treatments were applied in the main plots, the rice genotypes were placed in the sub- plots and the potassium rates were put in the sub- sub plots. The main obtained results indicated that Giza179 produced higher grain yield and its attributes followed by GZ7112 rice line under continuous flooding (W) without any significant decrease in yield up to 8W and then significantly decreased under12W treatment. The amount of water saved due to increasing irrigation intervals compared to continuous flooding were (10.36 and 8.37 %) for Giza179 and (10.50 and 10.36%) for GZ7112 under 4W treatment and (17.81 and 23.66%) for Gzia179 and (13.33 and 18.44%) for GZ7112 with 8W treatment, while under 12W water saved was about 23.91 and 27.90 % with reduction in grain yield about 22.42 and 24.71 % in 2012 and 2013 seasons respectively. Over both season using Giza179 and GZ7112 rice genotypes which gave higher yield about (9.70 and 9.33 t/ha), water saved (20.73 and 15.88 %) and water use efficiency (0.90 and 0.81 kg/m3) for both genotypes respectively. It means that the total water input ranged from 11260.88 and 10006.80 m3/ha (which equal about 4700 m3/fed) under 8W treatment using Gzia179 rice variety compared with national average which reaches to 1428.57 m3/ha (which equal about 6500 m3/fed). The application of potassium up to 108 K2O/ha (K3) significantly increased rice yield and relatively mitigated the undesirable effect of water stress resulted in increase the WUE and water saved %.

COMPARATIVE STUDIES FOR GRAIN YIELD, GRAIN QUALITY, COOKING QUALITY AND NUTRITIONAL VALUE TRAITS OF BLACK RICE VARIETY
Food industry shift to use modern techniques and non-traditional components in the production of traditional foods for maximizing the nutritional value of these products inductive meet growing consumer appetites for this type of food. Scientists have discovered that biological compounds with antioxidant effects, such as phenolic and polyphenols compounds have a role in the prevention and treatment of the body from heart disease, cancer tumors and some diseases of aging, such as Alzheimer's. The black rice, a variety tinted widespread in the countries of Asia, and newly cultivated in Egypt, a distinct source of these compounds vital antioxidant. This research aims to field and technological evaluation of black rice variety which newly transferred to Egypt, and the production of sponge cake with a high content of antioxidants using rice flour black.
Field experiments were conducted for four successive rice growing seasons ( 2010, 2011, 2012 and 2013) at the experiential Farm of Rice Research and Training Center (RRTC), Sakha, Kafer El-Sheikh, to study agronomic characters as well as grain quality characters of black rice variety as compared to different rice varieties (Egyptian Yasmine and Pusa Basmati 1 as aromatic varieties and Sakha105 as a high yielding variety). Laboratory studies were carried out at RRTC and at Food Technology Research Institute, Giza, Egypt to evaluate quality of black rice flour.
Concerning agronomic and grain quality characters, black rice variety gave the highest values of grain width mm, head rice%, elongation % and protein content%. On the other hand, black rice variety recorded the lowest values of plant height (cm), heading date (days), panicle length (cm), no. of panicles hill-1, panicle weight (g), no. of filled grains panicles-1, grain yield t ha-1 andgrain length mm. The results showed also that black rice flour had higher content of protein, phosphorus, iron, total dietary fiber, ash and ether extract than wheat flour (72% extraction). Black rice flour was superior as compared to wheat flour in terms of antioxidant content. Replacement of 6% black rice flour with wheat flour increases each of resistance of extension (B.U.), extensibility (mm), proportional number and energy value (cm2) of cake dough. It also increases protein content (%), total dietary fiber content (%) and ash content (%) of cake.
This study can guide in the selection and production of rice varieties with enhanced nutritional qualities, suggesting the use of black rice variety in food industry.

EFFECT OF GRAFTING ON THE CUCUMBER YIELD AND QUALITY UNDER HIGH AND LOW TEMPERATURES.
Two experiments were conducted during the summer and winter seasons of 2013 to study the effect of grafting using different rootstocks on the yield and quality and chemical analysis of cucumber (Cucumis sativus L.) cultivar "Hady" under high and low temperatures. The experiments consisted of 5 treatments, 4 rootstocks, namely Bottle Gourd (Lagenaria siceraria Standl.), Supper Shintosa (Cucurbita maxima Duchesne×Cucurbita moschata Duchesne), Squash 3 (Cucurbita pepo) and Ferro’ (C. maxima × C. moschata), in addition to non-grafted control. Data were recorded on plant length and physical characters of fruits 30, 60 and 90 days after planting, early and total yield/m2, chemical characters (percentage of dry matter, TSS and total and reducing sugars) of cucumber fruits and percentage of N, P and K in cucumber leaves. The results indicated that Ferro rootstock increased plant height, physical characters, early and total yield of cucumber fruits in both summer and winter seasons, as compared with non-grafted control. No significant effect was detected from using rootstocks on N, P and K percentage in cucumber leaves, except grafting cucumber on Bottle Gourd rootstock which significantly increased N% only in the winter season. Chemical contents of cucumber fruits were not affected by grafting in summer season, while Bottle Gourd increased total sugars and Ferro rootstock caused significant increase in the percentage of dry matter and reducing sugars in winter season as compared with non grafted plants.

EFFECT OF NITROGENOUS FERTILIZER RATES ON RICE YIELD, YIELD COMPONENTS AND INSECT INFESTATION OF SOME RICE CULTIVARS
Rice is a very important cereal crop in Egypt and allover the world. In Egypt, it is an essential food crop because of shortage in wheat production, and nitrogen fertilizer is crucial to obtain a good yield. Two field experiments were conducted in 2011 and 2012 rice seasons at the Experimental Farm of Rice Research and TrainingCenter, Sakha, kafr El-Sheikh, Egypt. The experiments aimed to evaluate yield and its components of four rice cultivars; Sakha 101, Giza 178, Egyptian Jasmine and rice Hybrid 1. These cultivars were tested under five nitrogen levels; 0, 23, 46, 69 and 92 kg N/ fed. in the form of urea (46.5 % N ). Also, the insect infestations of rice stem borer, Chilo agamemnon Bles. and rice leaf miner, Hydrellia prosternalis Deeming. were evaluated. The main results proved the superiority of Egyptian Hybrid 1 rice cultivar, concerning filled grains and yield. The second rank was that of Sakha 101 cultivar as it gave the highest values of 1000-grain weight and harvest index. According to the current data, it is recommended to use 69 kg N/ fed. ( not 92 kg ) for fertilizing the tested cultivars, as no significant yield differences were found between the two nitrogen levels. On the other hand, it is important to avoid using overdoses of nitrogenous fertilizers because they encourage the infestation by rice stem borer and rice leaf miner.

TWO PHENOLIC ACIDS AMELIORATE THE ADVERSE EFFECTS OF SALT STRESS ON Zea mays L. SEEDLINGS.
Pot experiments were conducted to evaluate the effect of foliar application of salicylic acid (3 mM) and benzoic acid (3 mM) on nitrate content and nitrate reductase activity in leaves of Zea mays seedlings grown under high salt stress (50 mM NaCl). Salinity treatment caused diminishment of the nitrate content and nitrate reductase activity by approximately 78% and 65% respectively.
Supplements of salicylic acid and benzoic acid partially alleviated the depressive effect of salinity on the two parameters, but did not completely recover to control values. Salicylic acid supplement proved to be more effective in encountering the deleterious effects of salinity.

PARTIAL SUBSTITUTION OF CHEMICAL FERTILIZATION OF ROSELLE PLANT (Hibiscus sabdariffa L.) BY ORGANIC FERTILIZATION IN PRESENCE OF ASCORBIC ACID
Two field experiments were conducted to evaluate the effect of different levels of organic fertilizer (5, 10 and 15 m3 compost/fed.) when used with half dose of chemical fertilizer compare with full dose of chemical fertilizer in presence of ascorbic acid foliar spraying (0.0, 100 and 200ppm) on some growth parameters, yield and chemical constituents of roselle (Hibiscus sabdariffa L.) plants during 2011 and 2012 seasons. Interaction effects between ascorbic acid and the used fertilization treatments on growth and productivity were studied as well.
The results showed that either treatment of half chemical fertilizer dose+15m3 compost/fed. or full chemical fertilizer dose significantly induced the highest values of plant height, number of leaves, branches and fruits /plant, leaves dry weight/plant, fresh and dry weight of branches and sepals/plant, seed yield/plant, seed fixed oil per plant and per fed., sepals anthocyanin and vitamin-C content, leaf N, P, K, Fe, Zn and Mn uptake, leaf total carbohydrates, total sugars, total free amino acids, auxins, gibberellins and cytokinins content, but they decreased the values of leaf abscisic acid, peroxidase, catalase and superoxide dismutase contents. However, the highest number of leaves, branches and fruits/plant, the heaviest leaves dry weight/plant, the heaviest fresh and dry weights of sepals/plant, the highest seed fixed oil content per plant and per fed., the highest sepals vitamin-C contents, the highest leaf N, K, Fe and Mn uptake, the highest values of chlorophyll a&b, carotenoids, total carbohydrates, total sugars, total free amino acids, gibberellins and cytokinins as well as the lowest values of abscisic acid, peroxidase and superoxide dismutase were recorded by half chemical fertilizer dose+15m3 compost/fed. treatment combined with 200ppm ascorbic acid. Besides, the highest sepals anthocyanin content was recorded by the combined treatment between half chemical fertilizer dose+10m3 compost/fed. and 200ppm ascorbic acid in both seasons. Moreover, the tallest plants, the heaviest fresh and dry weight of branches/plant, the highest seed yield/plant, the highest leaf P and Zn uptake and the highest leaf auxins content of roselle plants were scored by the full chemical fertilizer dose combined with 200ppm ascorbic acid, followed by the combined treatment between half chemical fertilizer dose+15m3 compost/fed. and 200ppm ascorbic acid in both seasons.
Consequently, it could be safely treat roselle plants with the combined treatment between half dose of chemical fertilizer+15m3 compost/fed. and ascorbic acid at 200 ppm for enhancing growth and productivity of this plant.

COMPLEMENTED EFFECT OF GLYCINE BETAINEA AND BIOFERTILIZERS ON GROWTH AND PRODUTIVITY OF SWEET PEPPER (Capsicum annuum L.) PLANT UNDER HIGH TEMPERATURE CONDITION.
Temperature is one of the major factors are being controlling and/or limiting growth and development of plants. The effect of plant growth promoting rhizobacteria (PGPR) (mixture of Azospirillum lipoferum, Paenibacillus polymyxa and Bacillus circulans), mycorrhizae (AM) and foliar application with glycine betaine (GB) at 0, 10 &15mmol/L individually or in combination on some growth aspects, photosynthetic pigments, microbial activities, minerals and some bioconstituents, endogenous phytohormones, flowering, fruiting and fruit quality of sweet pepper cv. California wander was studies during 2011 and 2012 seasons under open field at high temperature condition. Results indicated that, different applied treatments significantly increased most growth parameters as number of branches and leaves per plant, leaf area per plant, leaves and shoot dry weight per plant and leaf area ratio as well. Furthermore, photosynthetic pigments, NPK, total sugars and total free amino acids concentration in leaves recoded the maximum values when plants treated with PGPR, AM and foliar application with GB at 10 mmol/L as compared with those of individual application or untreated ones. Moreover, individual application with PGPR, AM and / or GB at 10 mmol/L enhanced the microbial activities in rhizosphere of the pepper plants compared with untreated ones. Also, biofertilizers and GB treatments increased auxin, gibberellin and cytokinin levels in sweet pepper shoots at 65 days after transplanting during 2012 season whereas abscisic acid was decreased. Moreover, the highest early and total yield were obtained when plants were sprayed with GB at 10 mmol/L and treated with microbial consortium (PGPR & AM). In addition, chemical composition of minerals and some bioconstituents such as total carbohydrates, vitamin C, total soluble solids in sweet pepper fruits were also increased at the same treatments. Hence, it could be recommended that foliar application with GB at 10 mmol/L in the presence of PGPR and AM as biofertilizers can be used to increase yield and fruit quality of sweet pepper plant when grown at high temperature condition.
