Abstract:
A field experiment was conducted at the Agronomy Instructional Farm, Department of Agronomy, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to study the effect of Fe and Zn enriched organics on nutrient content and uptake by potato in loamy sand (Typic Ustipsamments) during the rabi seasons of 2016-17 and 2017-18. The pooled results revealed that an application of 5 t vermicompost ha^-1 resulted in significantly higher concentration of Fe and Zn and also higher uptake of N, P, K, Fe and Zn by both tuber and haulm of potato as compared to 20 t FYM ha^-1_. An application of organics 2 t ha^-1 enriched with 6 kg Fe and 4 kg Zn recorded significantly higher N, P, K, Fe and Zn content in tuber and haulm of potato as compared to no application of Fe and Zn. The maximum concentration and removal of N, P, K, Fe and Zn by both tuber and haulm were registered under treatment of organics @ 2 t ha^-1 enriched with 6 kg Fe and 4 kg Zn ha^-1 over control (No Fe and Zn). Combined application of 5 t vermicompost ha^-1 + vermicompost @ 2 t ha^-1enriched with 6 kg Fe and 4 kg Zn recorded significantly higher content of Fe and Zn and uptake of N, P, K, Fe and Zn by both tuber and haulm as compared to control (No Fe and Zn).
