Abstract

The Vertisols of Malaprabha Command are deficient in iron (4.1 ppm) and zinc (0.57 ppm) due to high pH and calcareous nature. Soil moisture status also influences the availability of nutrients. Effect of irrigation levels and micronutrients application individually and in combination on maize yield, consumptive use (Cu), and WUE and nutrients uptake was studied for three years (2002–03 to 2004–05) in vertisol of Malaprabha command area. Response of maize was significant due to irrigation levels as well as micronutrients application. The highest mean yield of 66.74 q ha−1 was obtained in treatment receiving ZnSO4 (25 kg ha−1) + FeSO4 (25 kg ha−1) followed by ZnSO4 (10 kg ha−1) + FeSO4 (10 kg ha−1) application (63.08 q ha−1).
