Impacts of Different Irrigation Schedules and Nutrients Management Practices on Economics of Wheat

Abstract

A field investigation was conducted during two kharif seasons of 2020-21 and 2021-2022 at Agriculture Research Farm, Rabindranath Tagore University, Raisen, Madhya Pradesh, India, to evaluate the effect of different irrigation scheduling and nutrient management practices on yield and economics of wheat crop in split-plot design with three replications. The irrigation level N0 - No irrigation, N1- One Irrigation at CRI (crown root inition) stage, N2- One Irrigation at CRI & one irrigation before flowering were arranged in main plots whereas nutrient management treatments of N0 – Control, N1-100% RDF + FYM @ 2.5 t/ha. + Azotobacter, N2 - 100% RDF + Vermicompost @ 1.5 t/ha + PSB, N3 - 50% RDF+ FYM@5.0 t/ha, N4 -50% RDF+ Vermicompost@2.5 t/ha were used in the sub plots. The results shown that one Irrigation at CRI & one irrigation before flowering along with application of 50% RDF+ FYM@5.0 t/ha found to be best in the terms of grain and straw yield 28.70 and 41.88 q ha-1 in 2021 and 29.52 q ha-1, 42.13 q ha-1 in 2022. Minimum yield and cost benefit ratio recorded under control plot. The study suggests economically combinations of currently used irrigation scheduling and nutrient management practices that may help farmer to obtaining optimum yield.

Effect of Irrigation Scheduling and Different Sowing Dates on Water Productivity and Economics of Wheat (Triticum aestivum L.)

“…The table below includes both the fixed cost associated with treatments and the average cost of cultivation (Rs. ha -1 ) [5,9].…”

“…The sowing timing is the most significant element in crop production. Due to the longer growing season, early seeding has been found to produce higher yields than late sowing [5]. Delay sowing from November 20 forward resulted in a 39 kg ha -1 day -1 decrease in wheat grain production.…”
