Exogenous application of Brassinoide and salicylic acid enhances on growth, yield and nutritional quality of Indian bean (Lablab purpureus L. var. typicus)

Abstract

The field experiment was conducted at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Jaipur) during kharif season 2016-2017. The experiment consisting five bio-regulators (control, brassinoids @ 0.5 ppm, brassinoids @ 1.0 ppm, salicylic acid @ 100 ppm and salicylic acid @ 150 ppm) with three replications. The application of brassinoids 1.0 ppm to the Indian bean significantly increased the plant height (cm), number of branches per plant, dry matter accumulation, CGR at 45-60 and 60-75 days after sowing, chlorophyll content in leaves, leaf area, number of green pods per plant, average pod weight (g), green pod length (cm), number of pickings per plant, green pod yield per plant, green pod yield per plot, green pod yield (74.11 q/ha), and protein content as compared to control. Whereas, crude fibre content was found minimum with salicylic acid @ 150 ppm and found at par to brassinoids @ 1.0 ppm and 0.5 ppm. The application of brassinoids @ 1.0 ppm found significantly statistically best with net returns (₹ 67,752/ha) and highest B:C ratio (2.56).
