Optimization of deficit irrigation and nitrogen fertilizer management for peanut production in an arid region.

ABSTRACT: Deficit irrigation (DI) has been emerging as an important technique for enhancing crop water productivity (WP). However, advantage of DI under varying nitrogen (N) application rates remains unclear. Field experiments were conducted during 2012-2014 to investigate the impacts of six irrigation levels[FI (full irrigation), DI₁₀, DI₂₀, DI₃₀, DI₄₀ and DI₅₀, with irrigation amount of 100, 90, 80, 70, 60 and 50% of ETc, respectively) and four N application rates (N₀, N₁₀, N₂₀ and N₃₀, with 0, 10, 20 and 30 kg N ha^-1, respectively) on WP, yield, quality, and net economic return of peanut in hot arid region of India. We used Technique for Order Preference by Similarity to an Ideal Solution
