Effect of land configuration and nutrient management on growth analysis and yield of kharif groundnut (Arachis hypogaea L.) 

Abstract

A field investigation was under taken during kharif seasons of 2019 and 2020 at the Research Farm of Indira Gandhi Krishi Vishwavidyalaya, College of Agriculture and Research Station, Raigarh (CG). The results of the experiment revealed that ridge and furrow land configuration method recorded the maximum values of growth analysis parameters (leaf area index, leaf area duration, crop growth rate and net assimilation rate) and pod as well as haulm yields of groundnut and these parameters were the minimum under flatbed land configuration method. Further, the relative growth rate analysis factor was increased substantially between sowing to 50 DAS. Thereafter, continuous decrease trend was noticed till 100 DAS under different land configurations treatments, Similarly, among the nutrient management practices, 100% RDN (30, 60 and 30 kg of N, P2O5 and K2O ha-1) +5t FYM ha-1 recorded the maximum values of above all growth analysis characters as well as pod and haulm yields of kharif groundnut. The lowest values of these characters were recorded with absolute control practice of nutrient management system. Further, the relative crop growth rate obtained values were more or less equal under nutrient management treatments in relation to different time intervals.
