Two field trials were conducted during 2015/16 and 2016/17 winter seasons, at Agric. Res. Stat., Fac. Agric., Cairo Univ., Giza, Egypt, to study response yield and its attributes of chickpea to zinc (Zn), Boron (B) and molybdenum (Mo) in four combination at three growth stages; V3: vegetative stage (30 days after planting), R1: start of flowering (45 days after planting) and R6: pod initiation (60 days after planting). The treatments of micronutrients foliar application were T1 (application with tap water), T2 (Zn 0.5 g/l + B 0.5 g/l), T3 (Zn 0.5 g/l + Mo 0.5 g/l), T4 (B 0.5 g/l + Mo 0.5 g/l), T5( Zn 0.5 g/l + B 0.5 g/l + Mo 0.5 g/l). The T5 treatment (Zn + B + Mo) produced significantly the greatest seed yield feddan-1 (702 and 727 kg), stover yield feddan-1 (2275 and 2276 kg), harvest index (23.6 and 24.1%) respectively, in both seasons. The results indicated that the spraying time of microelements did not significantly effect on yield traits in 2015/16 and 2016/17 seasons. The greatest productivity of seed (705 and 732 kg/ fed.) in 2015/16 and 2016/17 seasons, respectively was recorded by combined application of zinc (0.5 g/l) + Boron (0.5 g/l) + molybdenum (0.5 g/l) as foliar spray at start of flowering stage compared with other tested treatments. Combined application of zinc, boron and molybdenum as foliar spray at 45 DAP significantly enhanced the crop yields and protein (%) in seed of chickpea.

Two field experiments were carried out at Rice Research and Training Center, Sakha, Kafr El-Sheikh, Egypt during 2018 and 2019 cropping seasons. Experiments aimed to determine the impacts of different deficit irrigation treatments on the available soil nutrients, N, P, K and Zn uptakes, rice yield and water use efficiency. The field experiments were laid out in a strip-plot design with four replications. The horizontal plots were devoted to the four irrigation treatments: continuous submergence (W1), intermittent irrigation at 6-day intervals (W2), intermittent irrigation at 9-day intervals (W3) and intermittent irrigation at 12-day intervals (W4), while vertical plots were occupied by the three rice genotypes, namely Giza 177, Giza 179 and GZ10154. Intermittent irrigation at 6-days intervals (W2) treatment, recorded the highest available NH4+-N, NO3--N and K concentrations in the soil. The highest values of available-N and available-P concentrations in the soil were obtained with (W1) while (W4) recorded the lowest values. The N, P, K and Zn uptakes were significantly affected by the prolonged irrigation intervals. Rice yield and its attributes decreased significantly as irrigation intervals increased up to 12-day (W4) in both seasons. The highest values of plant height, number of panicles m-2, panicle weight (g), 1000-grain weight (g), number of filled grains panicle-1, grain and straw yields were obtained with (W1) followed by (W2) treatment, except panicle length and number of unfilled grains panicle-1 in both seasons. Water saved (%) ranged from 8.90% to 26.46% and from 17.47% to 27.25% in 2018 and 2019 seasons, respectively.

A pot experiment was conducted during two successive seasons 2017 and 2018 at experimental farm of Faculty of Agriculture, Cairo University, Giza, Egypt. The aim of this study is to determine the ability of Pennisetum setaceum cv. rubrum plant to grow in cadmium (Cd) contaminated soil (100 mg/kg). Also, investigate the effect of citric acid application (1 and 2 mmol/kg) on phyto-extraction of cadmium-contaminated soil. The results clarified that the presence of cadmium (100 mg/kg) in the soil caused low reduction in the herb growth compared to unpolluted soil. The reduction rates in both seasons were 20.33 and 26.47% for herb fresh weight, 5.08 and 14.79% for herb dry weight, 8.86 and 0.0% for number of inflorescences/plant, respectively. The treatment of citric acid 1 mmol/kg increased the Cd content 149.3, 137.5% in the herb, and 221.25, and 170.81% within plant root in both seasons, respectively compared to the control. Also, such treatment raised phenols content in the herb to 102.3 and 93.0% compared to control plants in both seasons, respectively. The results showed that translocation factor (TF) was bigger than one which means that the plants had accumulated the cadmium in their tissues; however the plant tolerated Cd-contaminated soil accompanied with high content in both phenols and catalase enzyme activity. It could be concluded that P. setaceum cv. rubrum is a promising plant for phytoremediation.

Ten competition periods as treatments (T1-10) could be valuable for predicting increase productivity (W) T1 to T5 were allowed to infest the crop and (WF) T6 to T10 was kept weed free, weed competition periods for W and WFi.e. 3, 6, 9, 12 Weeks after emergence (WAE) and up to harvest. So, two field experiments were conducted season 2018 and 2019. Critical Periods for Weed Control (CPWC) was determined based on relative percentage yield ton/h-1 (SY %) of weed free as a check by fitting curves regression models (linear and non-linear, which recommended losing yield value 10%. with seed yield reduction t/h-1 declined from 2.3, 2.28 WF to 0.39- 0.36 W as a checked treatment for 1st, 2nd seasons, respectively about 83.33%, 85% due to relative seed yield. Gompertz as a non linear regression equation recorded 0.99* The effects of treatment classified into 3 groups where A involved 5 superior treatments (T1, T7, T8, T9 and T10). However, T4 and T5 described inferior treatments which located in group C. Low of weed density and increasing of weed index (WI %) 80% observed for 1st season of T4 but T5 was translocated with increasing both weeds number and severed for weed index. It could be summarized that it should be keeping crop weed-free during stages 2nd week and continue until 8th week after crop emergence, which is providing maximum seed yield of soybean.

Two experiments were carried out at a private farm located in Dimiana village, Belqas District, Dakahlia Governorate, Egypt during the two consecutive summer seasons of 2018 and 2019 to study the effect of different rates of kaolin (0.0, 20, 40 and 60 g /l) in combined with calcium (0.0, 400 and 800 mg/l) on vegetative growth, water relations, leaf chemical composition as well as fruits yield and its quality of tomato.. The obtained results revealed that the highest values of plant height, leaf area per plant, leaf dry matter percentage, relative water content percentage, leaf pigments, fruit yield per plant as well as total marketable yield per feddan, vitamin C and lycopene content of tomato plant were achieved with kaolin at 40 g/l with significant difference comparing the other rates under study. While, increasing kaolin to 60 g/l decreased the above mentioned parameters during both seasons. Furthermore, increasing calcium rate from 400 to 800 mg/l increased tomato growth and productivity compared to control (untreated plants). In general, it could be concluded that spraying tomato plants with 40 g/l of kaolin combined with 800 mg/l of calcium, showed improvement in vegetative growth parameters, water relations, leaf pigments, fruits yield and its components as well as fruits chemical constituents under Dakahlia Governorate conditions.

Due to the increased water shortage and frequent drought in Egypt, it is essential to develop drought-tolerant plants. Therefore, five drought tolerance lines ofokra were used to develop superior hybrids under drought conditions, using a half-diallel mating design to produce fifteen hybrids. There were significant differences among the hybrids and their parents in mean squares for all studied traits. The hybrids (P2XP6), (P2XP3), (P1XP2) and (P2XP4) exhibited the maximum mid- parents (MP) and better parent (BP) heterosis for total yield/plant.The mean squares for general (GCA) and specific combining abilities (SCA) were significant for studied traits, which indicates the importance of additive and non-additive gene actions in the inheritance of the studied traits in okra.The magnitudes of additive genetic variance (σ2A) were larger than their corresponding non-additive genetic variance (σ2D) for plant height, number of branches per plant, number of days to 50% flowering, pod length and total yield/plant. This revealed the major effect of additive inheritance for these traits.Genetic analysis illustrated that broad sense heritability (h2bs%) values were larger than their corresponding heritability in narrow sense(h2ns%) for all studied characters.As for the correlations between yield component traits, there were significant and positive genotypic correlation (rg) among total yield/plant and plant height, average pod weight and number of pods/plant. Overall, these crosses are promising hybrids with high yielding ability, and could be commercially recommended to improve economical traits in okra under drought conditions.

Two field experiments were raised at Farm of El-Sirw Agriculture Research Station, Dammitta province, Egypt through 2018 and 2019 seasons. The present study was performed to compromise the influence of rice straw biochar and other two soil amendments of rice straw compost and gypsum on rice growth and yield of three contrasting rice varieties,Giza177 (salt sensitive variety), Giza 178 (salt tolerant variety) and Giza179 new (salt tolerant variety) under saline sodic soil. The field experiments were designed in spilt plot design with four replications. The three rice varieties were scattered in the main plot, whereas the amendment treatments; control, gypsum(G), rice straw compost (RS) and rice straw biochar (RSB) were put in the subplots. The tested rice varieties were significantly different in growth parameters, yield attributes and yields in both seasons. Giza 179 as a new salt tolerant variety provided the maximum values of rice growth characteristics and most of yield contributes and yields without significant difference with Giza178 were considering yields. Applying varying soil amendments greatly improved rice growth and yields in addition to yield attributes comparing to the control treatments. Rice straw biochar surpassed significantly other two amendments, particularly in the first season, meanwhile in the second seasonthe three soil amendments were equally in increasing grain yield. Thereby, rice straw biochar could be applied each two years but rice straw compost has to apply in two successive season to get its efficiency.
