“…Delaying irrigation until reaching 70% of the field capacity led to a decrease in the characteristics of pod yield/plant, seed yield/plant, and shelling percentage compared with the normal irrigation (control). Drought stress limits photosynthesis due to stomatal (stomatal closure) and non-stomatal (impairments of metabolic processes) factors, resulting in less assimilate production for plant growth and yield, these results of irrigation treatments in our present study confirm the findings of previous investigators (Arunyanark et al, 2009;Dinh et al, 2013;Arruda et al, 2015;Nassar et al, 2018).…”

“…), as it recorded the highest values for the yield components(pod yield per plant, seed yield per plant,100-pod weight and 100-seed weight) compared to the rest of the treatments. These results are in full harmony with those of Songsri et al, (2008), Farooq et al, (2009) and Nassar et al, (2018). Si's superiority over other foliar treatments (K and Se) in terms of yield could be because of Si's role in root development and water uptake under drought stress conditions (Gomaa et al, 2021).…”

With water resources becoming more limited in arid and semi-arid regions, water-saving strategies are needed to reduce agricultural water use. A field experiment was carried out at EL-Bostan Agricultural Farm, Faculty of Agriculture, Damanhur University, EL-Behira Governorate, Egypt, during two successive summer seasons 2020 and 2021 to investigate the effect of foliar application of potassium, silicon, and selenium on some growth characteristics, chemical properties, yield, and some related traits of the peanut crop (Arachis hypogea L.) under water deficit conditions. A split-plot design was used; three depletion ratios (50, 60, and 70%) of available water were applied in the main plots, while four spray treatments (tap water (as control), 2% K2SO4, 2 mM Si as Na2O3Si.9H2O, and 30 g Se/ha as Na2SeO4) were laid in the subplots. The findings revealed that increasing the depletion percentage from 50% to 70% resulted in a significant decrease in all traits except the shelling percentage. Potassium foliar application produced the highest plant height and the number of branches per plant, whereas silicon treatment resulted in the highest pod yield per plant, seed yield per plant, shelling percentage, 100-pod weight, 100-seed weight, and pod yield. Treatment with selenium led to high chlorophyll contents. The interaction between the two studied factors showed that irrigation after a 50% depletion ratio with potassium foliar application recorded significant values of the plant height and number of branches. The highest content of chlorophyll was achieved when the crop was treated with selenium under irrigation after depleting 70% of the available soil moisture content. The highest values of pod yield per plant, seed yield per plant, and pod yield (ard/fed) were observed when the peanut was irrigated after a 50% depletion ratio with silicon foliar application. The best shelling percentage was achieved with potassium under a 70% depletion ratio. The treatment with silicon under a 60% depletion ratio recorded the heaviest 100-pod weight and 100-seed weight. When peanut plants are subjected to water stress, treatment with silicon, potassium, or selenium reduces crop losses and increases plant tolerance to stressful water conditions.

“…In another experiment with winter wheat, principal component analysis was found of 96.063% from the variance which indicated limited variation in the response to reduced N fertilization and vice versa (Iancu Paula et al 2019). Others authors also observed that the rank of genotypes for some studied traits under water stress changes from that under well watering conditions (Nassar et al 2018).…”

“…It can see that drought can lead to a substantial decline in yield and this reduction depends on the genotype. Water stress causes a significant reduction in groundnut lines pod yield/ha and other characteristics (Nassar et al, 2018), so that water availability is a critical factor for a successful groundnut production.…”

Water is essential to maximize crop yield and quality. This natural resource has assumed huge importance, especially in the warmest areas, where drought and environmental degradation has affected agricultural production. In order to identify drought tolerance of some groundnut genotypes and to investigate the relationships between seed yield, quality and drought tolerance indices a study was made using 10 promising genotypes. The experiment was carried out during 2014-2017 and sowed under randomized block design with four replicates. It included three factors: two levels of irrigation (a1 – non - irrigated and a2 - irrigated), two levels of fertilization (b1 – non-fertilized and b2 - 100 active Nitrogen/ha) and genotype (C1-C10). Seed yield depending on the influence of the factor, varied from 535.95 Kg/ha (non-irrigated) to 2020.95 Kg/ha (irrigated); from 1055.30 Kg/ha (non-fertilized) to 1501 Kg/ha (fertilized) and from 1111.30 Kg/ha to 1388 Kg/ha depending on genotype. Same influence factors for protein content varied from 25.65% (irrigated) to 28.61% (non-irrigated); from 26.33% (non-fertilized) to 27.93% (fertilized) and from 25.59% to 28.52% depending on genotype. Stress susceptibility index (SSI) varied from 0.964 to 1.040; Stress Tolerance Index (STI) from 0.138 to 0.435; Mean Productivity (MP) from 883.5 to 1616.0; Geometric Mean Productivity (GMP) from 750.3 to 1332.7; Tolerance index (TOL) from 933.0 to 1844.0; Harmonic Mean (HM) from 637.2 to 1099.0; Yield Index (YI) 0.777 to 1.308 and Yield Stability Index (YSI) from 0.236 to 0.309. High values of SSI, STI, YI, DI, RDI and SSPI indicate drought tolerance and those variants present high stability.

Peanut is relatively tolerant to drought stress but the pod yield is influenced by soil moisture availability especially during its critical phases. The experiment was objected to study yield response of genotypes and their tolerance to drought stress during generative growth stage. The experiment was conducted at Muneng Research Station, East Java with D3 climate type. The experiment was undertaken during dry season to avoid interference from rains to the treatment. The split-plot design with three replications was applied. The main plot was watering treatment i.e. water available during the growing season and water available during vegetative growth (up to 50 DAS). The subplots were 20 peanut genotypes. Weeding, pest and disease controls were intensively undertaken. The results indicated that the average dry pod yield of 20 genotypes under well watered and drought stress treatments were 2.345 t and 1.585 t/ha. Based on MP, GMP, STI, RED, TOL, and SSI it can be concluded that G1 and G12 were genotypes with high yield and drought tolerant but huge yield reduction under water-stressed condition. G8 was drought tolerant genotype with little yield reduction under stress condition. G11 was susceptible to drought with low productivity and low yield reduction under stress condition.
