Optimization of cropping pattern for the Bellan canal command of Urwa block of Allahabad, Uttar Pradesh

Abstract

The present study was suggesting optimization of cropping patterns for the Bellan canal command of Urwa block, Allahabad, Uttar Pradesh. Linear programming software LINGO-14 was used to allocate optimal area under different crop activities. The weekly gross irrigation demand was estimated using 23 years climatology data and the Penman-Monteith equation as well as effective rainfall. The weekly canal discharge, gross irrigation demand and present net discharge from minor irrigation structures were utilized for cropping pattern plan. Total 13 crops were included in the optimization plan. Three optimal crop plans were developed based on available canal water, and 60%, 80%, and 100% of the existing net draft of groundwater through minor irrigation structures. The annual return of Rs. 979.69, 980.05, and 980.42 lakhs which was about 1.605, 1.606, and 1.607 times of the net return under existing cropping pattern from Plans 1 with 60%, 2 with 80%, 3 with 100% of the existing net draft of groundwater, respectively. The study further concluded that with the use of available canal water and groundwater pumpage at the existing rate of its optimization, one can get 60% more profit than the existing cropping pattern.
