Water Relations and Nutrient Uptake as affected by Drought in Wheat - Yield losses in Spring wheat due to drought stress

Laboratory and wire house experiments were conducted to determine response of different spring wheat cultivars to water stress imposed after three and six weeks of seedling emergence. It was found that drought stress significantly decreased the water relation, nutrient uptake and grain yield of all the wheat cultivars. The late drought stress imposed six weeks after seedling emergence significantly reduced the uptake of nutrients than early drought stress which was imposed three weeks after seedling emergence.
