Silicon supplementation enhances productivity, water use efficiency and salinity tolerance in maize.

Drought and salinity stress severely inhibits the growth and productivity of crop plants by limiting their physiological processes. Silicon (Si) supplementation is considerd as one of the promising approaches to alleviate abiotic stresses such as drought and salinity. In the present study, a field experiment was conducted over two successive growth seasons (2019-20) to investigate the effect of foliar application of Si at two concentrations (1 and 2 kg Si ha) on the growth, yield and physiological parameters of three maize cultivars (ES81, ES83, and ES90) under three levels of irrigation salinity) [1000 (WS), 2000 (WS) and 3000 (WS) mg LNaCl].

Consecutive seasonal effect on yield and water productivity of drip deficit irrigated sorghum in saline soils.

Drought stress destructively affects the growth and productivity of sorghum crop, especially under saline soils. Therefore, Field trials were performed to determine the influence of water stress on water productivity (water productivity for grain, (G-WP) and water productivity for forage, (F-WP), yield of sorghum and soil properties in salt-affected soil (8.20 dS m) under different sowing dates and irrigation regimes.

Salt Distribution and Potato Response to Irrigation Regimes under Varying Mulching Materials.

Water scarcity and frequent drought spells are becoming critical challenges to sustainable agricultural development, especially in arid and semiarid regions. Thus, this work aims to investigate the effect of deficit irrigation and varying mulching materials on soil moisture content, salt distribution, and potato yield. The experiment consisted of three irrigation regimes (I, I, and I) of crop evapotranspiration (ETc), designated as I, I, and I of ETc, and five mulching treatments viz.
