Studies on preparatory tillage moisture conservation practices and nutrient management in barley cultivation under water stress condition

Abstract

A field experiment entitled Studies on preparatory tillage, moisture conservation practices and nutrient management in barley cultivation under water stress condition was conducted during consecutive years of 2017-18 and 2018-19 at Soil Conservation and Water Management Farm of the Chandra Shekhar Azad University of Agriculture and Technology, Kanpur-2, The treatment combination of three preparatory tillage viz., T1 treatment- one cross ploughing with cultivator, T2 treatment- one ploughing with disc harrow + one cross ploughing with cultivator, T3 treatment- one ploughing by disc harrow + one pass with rotavator, three nutrient management viz., N1 treatment- 100% RDF (60 Kg N + 30 Kg P + 30 Kg K /ha), N2 treatment- 75% RDF + 25% FYM, N3 treatment- 50% RDF +50% FYM and three moisture conservation practice, M1 treatment- control, M2 treatment- dust mulch and M3 treatment- pinoxaden 5EC at 50 g/ha + VAM at 15 Kg/ha. The treatment was laid out in split plot design with three replications with preparatory tillage in main plots, nutrient management in sub plots and moisture conservation practices in sub-sub plots. The results revealed that T3 treatment- one ploughing by disc harrow + one pass with rotavator, N3 treatment- 50% RDF +50% FYM and M3 treatment- pinoxaden 5EC at 50 g/ha + VAM at 15 Kg/ha produced significantly more growth parameters, yield attributes and yield, grain, straw, and biological yield, gross and net return, benefit: cost ratio and water use efficiency than the other treatments during both the years of study. Thus T3 treatment- one ploughing by disc harrow + one pass with rotavator, N3 treatment- 50% RDF +50% FYM and M3 treatment- pinoxaden 5EC at 50 g/ha + VAM at 15 Kg/ha is most productive and profitable for the barley crop. newline
