water shortage in the agricultural sector is currently a major challenge in crop production. the more efficient water usage is that which increases yield without increasing water use. thus, a determination of the water-yield relationship is essential. a field study was conducted to examine water-yield relations in three genotypes of soybeans, including optimum irrigation depth, a comparison of ...

The ridge furrow (RF) rainwater harvesting system is an efficient way to enhance rainwater accessibility for crops and increase winter wheat productivity in semi-arid regions. However, the RF system has not been promoted widely in the semi-arid regions, which primarily exist in remote hilly areas. To exploit its efficiency on a large-scale, the RF system needs to be tested at different amounts ...

Introduction Fungicides have been widely used on nearly every crop imaginable and are continually being developed and reformulated as more information on their efficacy on specific crops and pathogens is discovered. It is well known that fungicides are developed and used in order to have a direct effect on one or more pathogens, usually to prevent their establishment on a crop. By spraying fung...

investigation of physiological responses to water deficit in sesame (sesamum indicum l.) genotypes can help to identify effective mechanisms of plant resistance to stress. therefore, chlorophyll content, proline, soluble carbohydrates, net photosynthesis rate, stomatal conductance, maximum quantum efficiency (fv/fm), plant height and shoot dry weight in a complete block factorial pot experiment...

Deficient irrigation is a very significant study, especially with the limited water. Therefore, current research aims to study deficit depending on several different scenarios, by adding amounts of water and rates (10%, 30%, 50%, 70%, 90%) full changing time studying its effect productivity. The results showed that there clear productivity barley at level (10%-30%) for all dates when date first...

Despite the importance of Artemisia annua L. as the only source of the anti-parasitic drug artemisinin, little is known on the effects of biotic and abiotic stress on artemisinin accumulation. Water deficit is the most limiting factor on plant growth, however it can trigger secondary metabolite accumulation, depending on the plant growth stage and intensity. A. annua cultivated in growth chambe...

The present study was carried out at Sakha Agricultural Research Station (clayey soils) during 2018 and 2019 to find the role of water deficit on yield some relations for sorghum cowpea summer forage crops. Three irrigation levels were executed; 100% (full irrigation), 90% (10% deficit) 80% (20% deficit). Results showed that increasing deficit, markedly led decreasing fresh, dry plant height th...

in order to investigate the effect of hexaconazole (hex) on the increasing tolerance to water deficit stress of two soybean (glycine max l.) cultivars, an experiment was conducted in faculty of agronomy of tarbiat modares university as factorial experiment in randomized complete block design arrangement. factors examined in this study were included soybean cultivars (l17 and clark63), hex conce...
