Abstract

A field experiment was conducted on a Vertisol of Malaprabha right bank command (MRBC) of Karnataka for three years (2004–05 to 2006–07) to study the effect of moisture regimes and micronutrient application on okra (Abelmoschus esculentus L.) yield, water use efficiency (WUE), nutrient uptake and economics. Response of okra was significant due to both irrigation levels as well as micronutrient application. Highest fresh okra yield of 9.3 t ha−1 was realized when crop received irrigation at I2 moisture regime (1.0 IW/CPE). Application of micronutrients increased the yield of okra. The N, P, K, Zn and Fe uptake by the crop was significant due to moisture levels and micronutrient application. Interaction effect indicated that crop receiving irrigation level of 1.0 IW/CPE with application of ZnSO4 and FeSO4 each @ 20 kg ha−1 recorded significantly higher okra yield (9.3 t ha−1), WUE (30.27 kg ha−1) and B:C ratio (5.07).
