Abstract:
A field trial was conducted at Instructional cum Research Farm, DKS College of Agriculture and Research Station, Indira Gandhi Krishi Vishwavidyalaya, Raipur, (C.G.) to investigate influence of nipping and spacing on growth and yield of rainfed horse gram. The experiment used a factorial randomized block design with three replications and 10 treatments combinations with two factors. The factor one with two levels of spacing (C1- Broadcasting and C2- 30×10 cm) and second factor with five levels of nipping (N1- no nipping, N2- manual nipping at 25 DAS, N3- manual nipping at 25 and 40 DAS, N4- mepiquat chloride at 250 ppm and N5- chlormequat chloride at 250 ppm). Nipping and growth retardants spray was done at 40 DAS, Growth and yield parameters such as number of branches plant-1, number of pods plant^-1, number of seeds pod-1, 1000 seed weight (g) and harvest index were recorded. Spacing of 30×10 cm recorded significantly higher yield (795 kg ha^-1), whereas more number of branches (10.59), higher number of pods plant-1 (44.95) were recorded with a broadcasting. Spraying of mepiquat chloride at 250 ppm recorded significantly higher yield (867 kg h^-1), more number of branches (11.19) and higher number of pods plant^-1 (55.60), followed by spraying of chlormequat chloride at 250 ppm spray with a yield of 835 kg ha^-1. Among the treatment combinations, spacing of 30 × 10 cm with mepiquat chloride-250 ppm.
