Evaluation of velvet bean ( Mucuna pruriens L.) genotypes for growth, yield, L-dopa content and soil nitrogen fixation in rubber plantation under hill zone of Karnataka

Abstract

Mean performance of 11 velvet bean (Mucuna pruriens L.) genotypes for growth, yield and quality attributes indicated significant differences among the genotypes for all characters studied the genotype Arka Danavantri recorded significantly maximum vine length (294.13 cm), number of trifoliate leaves (93.57), number of branches (5.60), stem girth (6.81 mm), leaf area (18740.73 cm2), chlorophyll content (49.03 SPAD units), days to flower bud initiation (119.93), days to 50 per cent flowering (137.00), days to pod maturity (197.80), number of flowers per inflorescence (19.07), number of bunches per plant (4.87), number of pods per bunch (5.07), pod yield (154.69 g), seed yield (82.37 g), L-DOPA content (3.74 %) and its yield (3.08 g/plant) and (114.17 kg/ha) and soil nitrogen fixation (22.67 kg/ha).
