Effect of bioregulators on yield components, yield and quality of chickpea cultivars in hyper arid partially irrigated western plain zone of Rajasthan

An experiment was conducted at the Agronomy farm, College of Agriculture, SKRAU, Bikaner during Rabi 2008–09. The experiment comprised of four cultivars of chickpea (GNG 663, GNG 469, RSG 44 and Local) and four bioregulators spray (Control, DMSO, Cycocel and H₂SO₄). The results related that cultivar GNG 469 significantly increased the yield compared to other cultivars. Membrane stability index (%) was significantly higher in GNG 469 compared to RSG 44 and Local, being at par with GNG 663. Nutrient content, uptake and protein content significantly higher in GNG 469 over all cultivars. Foliar spray of bioregulators significantly increased pods/plant, seed & straw yield, membrane stability index, nutrient uptake over control.
