Effect of Irrigation Scheduling and Integrated Nutrient Management on Productivity Profitability and Quality of Urdbean Vigna mungo L

Abstract

The field experiment was conducted at the Soil Conservation and Water newlineManagement Farm of Chandra Shekhar Azad University of Agriculture and Technology, newlineKanpur, Uttar Pradesh to study the effect of irrigation scheduling and integrated nutrient newlinemanagement on productivity, profitability and quality of urdbean (Vigna mungo L.) was newlineconducted during summer season of 2022 and 2023. The experiment was laid out in a newlinesplit-plot design and replicated three times using urdbean variety Shekhar-2. The main newlineplot consisted of three different irrigation scheduling levels viz. I1 - 0.4 IW/CPE, I2 - 0.6 newlineIW/CPE and I3 - 0.8 IW/CPE. Sub-plots consisting of five different integrated nutrient newlinemanagement practices viz. F1 - 100% RDF, F2 - 125% RDF, F3 -75% RDF + 2.5 t newlineFYM/ha, F4 - 50% RDF + 5.0 t FYM/ ha and F5 - 50% RDF + 2.5 t FYM/ha + 1 t newlineVermicompost/ha. The current study aimed to investigate the effect of various irrigation newlinescheduling levels and different integrated nutrient management practices on growth newlinepatterns, yield attributes, yield, water use, quality and economics of urdbean. newlineThe result revealed that all growth parameters such as plant height, number of newlinebranches per plant, number of leaves per plant, and dry matter accumulation recorded at newline25 DAS, 50 DAS, and at harvest stages were recorded significantly higher with the newlineapplication of irrigation scheduling at 0.8 IW/CPE and treatment 50% RDF + 2.5 t newlineFYM/ha + 1 t Vermicompost/ha. Higher days taken to 50% flowering and days taken to newline50% pod maturity were found maximum with the application of irrigation scheduling at newline0.8 IW/CPE and treatment 50% RDF + 2.5 t FYM/ha + 1 t Vermicompost. The yield newlineattributes and yield such as number of pods per plant, number of seeds per pod, pod newlinelength and test weight, grain yield, stover yield, biological yield, and harvest index were newlinerecorded significantly higher with the application of irrigation scheduling at 0.8 newlineIW/CPE and treatment 50% RDF + 2.5 t FYM/ha + 1 t Vermicompost. Significantly, newlinehigher protein content in grain and protein yield
