“…Tifton 8 might be drought-tolerant in those categories, but in this study, it was only average for nutrient uptake and RNS. As suggested by Samarah et al (2004), peanut genotypes exhibiting smaller reductions in nutrient uptakes should be presumed to be droughtresistant, and RNS may involve drought tolerance mechanisms. Therefore, it can be hypothesized that peanut genotypes that can manage high nutrient uptakes under drought conditions could be presumed to be droughtresistant.…”

“…Such genotypic variability of peanut in yield is important in peanut breeding programs. Samarah et al (2004) stated that nutrient uptake in soybean under drought stress might have an important role in drought tolerance mechanisms. Therefore, yield difference under terminal drought may be due to the different nutrient uptake of peanut under limited soil moisture.…”

Different peanut yields under terminal drought might be due to the different nutrient uptakes among peanut genotypes. Nutrient uptake was presumed to be a drought-resistant trait and might involve drought tolerance mechanisms. The aims of this study, therefore, were to characterize the effect of terminal drought on peanut nutrient uptake and to investigate the genotypic variability of nutrient uptake and its interactions with terminal drought. Field experiments were conducted at the Field Crop

“…Similarly, K supplementation proved helpful in mitigating the adverse effects of water stress in peanut and sorghum (Umar, 2006). Accumulation of minerals under drought conditions might be an important trait of drought tolerance in tall fescue (Huang, 2001), soybean (Samarah et al, 2004), and chickpea (Gunes et al, 2006). However, differential responses among species and genotypes for nutrient uptake under drought stress were observed (Garg, 2003).…”

The objective of this study was to investigate the responses of peanut genotypes to midseason drought, regarding in particular nutrient uptakes and their correlations with biomass production and pod yield. The experiment was conducted during the dry seasons of 2011/12 and 2012/13. Five peanut genotypes with different levels of drought tolerance and 2 water regimes (well-watered and midseason drought) were laid out in a split-plot design with 4 replications. Midseason drought was imitated by stopping irrigation at 30 days after planting (DAP) and then rewatering at 60 DAP. The data were recorded for contents of N, P, K, Ca, and Mg in plant tissues, biomass production, yield components, and pod yield at harvest. The results showed that midseason drought significantly reduced the uptake of all nutrient elements. Peanut genotypes with higher levels of drought tolerance took up more nutrients than those with lower levels. The uptake of all nutrient elements contributed to biomass production, pod yield, and the number of pods per plant. ICGV 98305 was the best genotype with the highest uptakes of all observed nutrient elements.

“…Average wheat yield under rainfed conditions is very low (<600 kg/acre) compared to irrigated wheat (~1200 kg/acre). Among major yield limiting factors, drought is very important as it seriously affects plant growth, yield and mineral nutrition (Garg et al, 2004;Samarah et al, 2004). To ensure food security and sustainable economy, it is extremely important to find ways to improve drought tolerance of wheat.…”

Abstract:Silicon is known to ameliorate the deleterious effects of drought on plant growth. We evaluated growth of wheat (CV. Inqlab-91) on different soil water regimes as affected by Si application. Silicon was added in soil @ 50 mg/kg and 150 mg/kg of soil. Plants were grown with three levels of soil water contents viz 50%, 75% and 100% of field capacity. Water deficiency in soil significantly reduced shoot biomass and spike weight of wheat plants. Silicon application significantly (p<0.01) increased plant biomass, plant height and spike weight at all levels of water contents. Poor growth of plants in water deficient conditions was significantly improved with Si application. Silicon application significantly increased Si concentration and uptake in wheat plants grown at all three soil water levels. Mechanisms underlying growth improvement under drought are still unclear and must be explored.Keywords: Drought, silicon, wheat. ‫ﺍﻟﻘﻤﺢ‬ ‫ﻋﻠﻰ‬ ‫ﺍﻟﺴﻴﻠﻜﻭﻥ‬ ‫ﺇﻀﺎﻓﺔ‬ ‫ﺘﺄﺜﻴﺭ‬
