Effect of 25 Years of Continuous Fertilizer Use on Response to Applied Nutrients and Uptake of Micronutrients by Rice-Wheat-Cowpea System
In a twenty five years old long-term fertilizer experiment with rice-wheat-cowpea system on a mollisol at Pantnagar; rice and wheat responded well to applied N, Zn and FYM over the years; whereas, responses to other applied nutrients are improving with the passage of time owing to decline in their availability in soil. Uptake of micronutrients by the entire cropping sequence of rice-wheat-cowpea varied from 143 to 597, 2274 to 6169, 384 to 1234 and 119 to 521 g ha−1 for Zn, Fe, Mn and Cu, respectively. The highest removal of Zn by crops was observed under 100%NPK+Zn, while that of Fe, Mn and Cu was under 100%NPK+FYM. Removal of micronutrients by the annual cropping cycle depleted the availability of Zn, Fe, Mn and Cu in soil in the range of 0.02 – .0.37, 0.1–1.8, 0.1–1.6 and 0.1 – 0.2 mg kg−1, respectively under different treatments.
