Rice yield constraints and production technology: perception of farmers through PRA

摘要

In Durg District of Chhattisgarh, rice is cultivated on about 0.4 million ha, mostly under rainfed conditions. Average productivity is 1.53 t ha~(-1), slightly higher than that of the state (1.31 t ha~(-1)) but much lower than the national average (1.92 t ha~(-1)). The district receives an average annual rainfall of 1,286 mm, 70% of which occurs from mid-June to mid-September. Yield is limited by erratic distribution of rainfall, a small irrigated area with prolonged biasi/transplanting, little attention to timely insect/disease/weed management, imbalance in fertilizer use, and inadequate supply of goodquality seed (Singh 1993).
