Abstract:
A field experiment was conducted during Rabi 2019-20 at farmer field kasbe camp, Raichur, Karnataka to assess the effect of foliar application of nutrients and growth regulator on growth, yield and economics of black gram. The experiment was conducted in RCBD (Randomized Complete Block Design) with three replications and eight treatments. The results revealed that foliar spray of T₆ {DAP (2%) + ZnSO₄ (0.5%) + FeSO₄ (0.5%) NAA + (40ppm)} has registered higher growth parameters viz., plant heightand number of branches per plantat 30, 60 DAS and at harvest. Similarly the same treatments also recorded significantly highestseed yield parameters viz., clusters per plant, pods per cluster, pods per plant, pod length, seeds per pod, seed yield per plant, seed yield per plot, seed yield per hectare. Whereas cost of cultivation, gross returns, net returns and B:C ratio were significantly highest at T₆ {DAP (2%) + ZnSO₄ (0.5%) + FeSO₄ (0.5%) NAA + (40ppm)} compared to control and other treatments.
