Effect of spacing and levels of phosphorus on the growth and yield of green gram (Vigna radiata) under rainfed condition of Nagaland

Abstract

The field experiment conducted in the experimental farm of School of Agricultural Sciences and Rural Development (SASRD), Nagaland University during kharif season (June-September) of 2016 revealed that spacing at 30 x 10 cm recorded significantly the higher plant height (48.10 cm), number of leaves (5.47), shoot dry weight (2.88 g plant-1), LAI (2.88) and yield attributes such as number of pods plant-1 (17.00), length of pods (6.81 cm), seed yield (688.54 kg ha-1) and stover yield (1917.81 kg ha-1) respectively. Application of phosphorus at 40 kg ha-1 recorded significantly the higher plant height (49.37 cm), number of leaves (5.73), shoot dry weight (3.34 g plant-1), LAI (3.34), CGR (6.37 g m-2 day-1) and yield attributes such as number of pods plant-1 (17.56), length of pods (6.91 cm), seed yield (737.42 kg ha-1) and stover yield (1973.01 kg ha-1) respectively.
