Effect of chelated micronutrients on the yield attributes and yield of rice

Abstract

Iron and Zinc were the yield limiting factor found to be deficit in the soils of Kallikudi block of Madurai district, Tamil Nadu. Therefore a field experiment was conducted to evaluate the effect of yield attributes and yield of rice under various doses of chelated micronutrients at the farmer’s field during Nov 2018-Jan 2019 in a randomized block design with five replications. Fourteen treatments were imposed and the results revealed that the application of chelated micronutrient mixture (Zn lysinate + Fe methionate) @ 12.5 kg ha-1 (T13) along with recommended dose of fertilizers (RDF) increased the yield attributes viz., number of productive tillers (14.6), number of filled grains per panicle (228), thousand grain weight (12.99 g), grain yield (6595 kg/ha) and straw yield (8845 kg/ha).
