Abstract:

Thiourea is a sulfhydril compound-containing SH group considered responsible for diverse biological activities in higher plants. The application of thiourea has been reported to improve the photosynthetic efficiency, transport of assimilates to grains and harvest index and delay chlorophyll degradation, leaf aging and senescence resulting in higher yields and water use efficiency (WUE). Recent studies have shown that thiourea application (seed treatment plus foliar spray) significantly enhanced seed yield, dry matter production, harvest index and WUE of clusterbean, moth bean and mung bean under rainfed conditions. The beneficial effects of thiourea have been attributed to its role in significantly increasing the net photosynthetic rate, chlorophyll concentration, nitrate reductase activity and level of soluble protein under water limited conditions. Furthermore, it showed additive effects with phosphorus and nitrogen nutrition on plant growth and leaf metabolism. It has been concluded that thiourea treatment can significantly enhance the productivity of arid legumes.
