Abstract


Water deficit conditions constitute the most significant factors leading to substantial and unpredictable decrease in crop yield. In order to redress the constraints and also increase crop productivity in a sustainable way a study was, conducted on utilization of Jatropha curcas deoiled cake through compost production. The deoiled cake was composted with three different components inorder to determine the role of compost on plant growth regulation in Brassica compestris under water deficit conditions. NRA, proline, photosynthetic pigments and SOD was assessed under irrigated and water deficit conditions. During stress period, increase in photosynthetic pigments and NR activity was noticed, in composts treated samples over control, on the contrary, significant alleviation in proline and SOD production in control plants under water deficit condition over irrigated as well as compost amended stressed plants. This study provides evidence for a beneficial effect of compost in enhancing drought tolerance under water deficit conditions.
