Abstract

A field experiment on physiological approaches for drought mitigation in cowpea(Vigna unguiculata L.) was conducted during rabi 2019, at MARS, UAS, Raichur. The experiment was laid out in randomized complete block design with three replications and thirteen treatments. Foliar spray was taken at 50 % flowering stage. Basal dosage of fertilizer 25:50 kg N: P2O5 ha-1 was applied to all plots. Among the treatments, foliar spray of pulse magic and chickpea magic @ 8 g l-1 had the profound effect in improving the growth attributes viz., plant height, leaf area index, leaf area duration, crop growth rate, specific leaf weight and net assimilation rate, ultimately seed yield. The above said treatments respectively recorded higher number of pods per plant (16.21 and 15.34), seeds per pod (13.67 and 13.14), test weight (13.38 and 13.21 g) and seed yield (1387.00 and 1346.00 kg ha-1), which was superior than other treatments. The yield enhancement might be due to the improvement in growth and yield attributes.
