Oil content and economic water productivity of soybean cultivars under different water availability conditions

ABSTRACT: This research evaluated the yield, water productivity, and economic productivity for oil content of three soybean cultivars under different conditions. The experiments were conducted in 2017/2018 2018/2019 harvests. experimental design consisted a two-factor randomized block, with first factor 5 irrigation depths, based on reference evapotranspiration (ETO), plus treatment without second was 3 cultivars. Results reported yield higher depths 75% (crop 1) 100% ETO 2). For evaluations highest results obtained at level 50% crop 1 25% 2. Cultivar BRASMAX Ponta had values production Valente both crops. In Crop 1, cultivar 2, values. Supplemental favored increase productivity. more efficient economical use water, it is necessary to smaller depths.
