Abstract


An experiment was conducted at Agricultural Research Station, Bhavanisagar to study the effects of deficit irrigation on groundnut with micro sprinklers. To identify the impact, water_x0002_yield relationship was derived and interpreted. The yield response factor (ky ) ranges from 0.45 and 0.42 (normal irrigation) to 1.72 and 1.70 (full deficit irrigation) for summer and Rabi seasons, respectively. From the results, the pod formation and flowering stages were more sensitive to moisture stress and irrigation during these stages is more important to overcome the yield reduction in groundnut
