Abstract

Rice needs micronutrients to grow to its full capacity, and zinc is one of the micronutrients that is most frequently lacking in both rice grains and soil. Two field experiments were conducted at Tamil Nadu Rice Research Institute, Aduthurai (110 N attitude, 790 31’ E longitude, 19.4 MSL) during Kharif and Rabi season respectively to evaluate and compare the application of different sources of Zinc with four Zinc efficient genotypes (CO 47, CO 51, ADT 37, ADT 47). The results showed that, among the genotypes, CO 51 performed well with respect to grain yield, straw yield, grain Zn content and straw Zn content followed by Co 47 followed by ADT 47 and ADT 37 in both the seasons. Among the soil application, Zn chelate recorded higher yield in all the genotypes, whereas among the combination, soil application of zinc sulphate as enriched Farmyard Manure along with foliar application of 0.5% ZnSO4 thrice recorded higher yield when compared to all other treatments.
