Abstract:
In order to examine effects of different concentrations of growth regulators (putrescine and IBA) on biochemical and yield contributing parameters on black gram a field experiment was carried out in the botany farm, college of agriculture, Nagpur during 2017-18. Foliar application of putrescine and IBA 25, 50, 75 and 100 ppm each was given at vegetative Stage (25 and 40 DAS) and the data were taken at 25, 40 and 55 DAS coinciding with vegetative stage, flowering stage and before harvest stage. Application of putrescine and IBA enhanced biochemical parameters viz., chlorophyll content, NPK content in leaves and protein content in grains, yield contributing characters viz., number of seeds pod-1,weight of 100 seeds, seed yield plant-1, plot-1 and ha-1. Analysis of data revealed that 100 ppm IBA considered as a most effective concentration in enhancing all biochemical and yield contributing parameters. But considering the B: C ratio two foliar sprays of 25 ppm IBAat 25 and 40 DAS was found more effective and economical treatment with increased yield of 30.47% having B:C ratio of 2.97 as compared to 2.54 in control.
