Effects of Organic Manures, Iron and Zinc Enriched FYM on Nutrients Content and Uptake by Pearlmillet in Sardarkrushinagar, India

A field experiment was conducted at the Agronomy Instructional Farm, Department of Agronomy, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar in India to study the effect of organic manures, iron and zinc enriched FYM on nutrients content and uptake by pearlmillet in loamy sand (Typic Ustipsamments) during the kharif season of 2022 and 2023. The pooled results indicated that application of castor cake @ 1 t ha-1 recorded significantly higher Nitrogen (N) and Phosphorus (P) content in both the grain and the straw and N, P, and Potassium (K) uptake by both grain and straw, while Iron (Fe) and Zinc (Zn) uptake by the straw of pearlmillet. Among different Fe and Zn supplementation, an application of 500 kg FYM ha-1 enriched with 1.25 kg Zn and 2.25 kg Fe recorded significantly higher P content in the straw, Fe and Zn content in the grain and straw and N, P, K, Fe and Zn uptake by the grain and straw of kharif pearlmillet.
