Long term effects of organic and inorganic fertilizers on nutrient use efficiencies and nutrient balance in rice: Rice cropping system
Author(s): G Kiran Reddy, SHK Sharma and M Srilatha
Abstract: Rice – rice cropping system is a predominant cropping system for livelihood security in India. Recent results indicate that agronomic efficiency, nutrient use efficiency are reducing due to continuous rice – rice cropping system. In this regard we analyzed the agronomic efficiency and nutrient use efficiency. The experiment consist of various combinations of organic and inorganic nutrients and was laid out in randomized com-plete-block design, with four replications. Greater agronomic efficiency and nutrient use efficiency were observed in 50% NPK and NPK+FYM treatments in general, lowest was observed in N alone treatment. This shows balanced application of major nutrients is essential for growth of crop. Nutrient balance was highest in NPK+FYM in N, P nutrition and for K nutrition it is highest in FYM treatment. Lowest was observed in control treatment.
