Abstract

The highest increase in grain Zn concentration was observed with foliar Zn application followed by ZnCU and least with soil Zn application. Among various Zn fertilization options, 3% ZnCU and soil application of Zn (5 kg/ha) was found most promising for improvement in growth attributes, grain and straw yields and Zn, N, P, K and S concentrations in rice grain. Therefore, Zn application through 3% ZnCU to rice is a recommendable option for improving rice productivity and its nutritional status in NEH region of India.
