Effect of fertilizer levels with respect to yield contributing characters and yield of summer green gram (Vigna radiata L.)

Abstract

The agronomic investigation entitled, “Performance of summer green gram (Vigna radiata L.) To fertilizer levels” was undertaken at Post Graduate Research Farm, Agronomy Section of Rajarshee Chhatrapati Shahu Maharaj College of Agriculture, Kolhapur (M.S.), India, during summer, 2019. The experiment was laid out in a factorial randomized block design were replicated thrice with twelve treatment combinations comprises three NP fertilizer levels NP1-75% of RDF, NP2-100% of RDF and NP3-125% of RDF and four potassium levels as a K0- 00 K2O Kg ha-1, K1- 15 K2O Kg ha-1, K2- 20 K2O Kg ha-1 and K3- 25 K2O Kg ha-1. The yield contributing characters viz., number of pods plant-1, weight of pods plant-1 (g), length of pod (cm), weight of dry pod yield plant-1 (g), number of seeds pod-1, 1000 grains weight (g), grain yield (q ha-1) and Stover yield (q ha-1) were influenced significantly with different fertilizer levels. The mean of these attributes were recorded highest with the application of NP3-125% of RDF followed by NP2-100% of RDF and K3- 25 K2O Kg ha-1. The mean grain yield (q ha-1) was highest with application of K3-25 kg K2O ha-1 (15.19 q ha-1) which was comparable with K2-20 kg K2O ha-1 (14.67 q ha-1) and stover yield (q ha-1) was significantly highest with application of K3-25 kg K2O ha-1 (34.62 q ha-1) over K2-20 kg K2O ha-1 (33.00 q ha-1).
