Effect of iron and zinc enriched organics on quality of potato in loamy sand Soil (Typic Ustipsamments) of Sardarkrushinagar

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 quality of potato in loamy sand (Typic Ustipsamments) during the rabi seasons of 2016-17 and 2017-18. An application of 5 t vermicompost ha-1 significantly enhanced quality parameters viz., total chlorophyll content in fresh leaf at 60 DAP, volume of tuber, total soluble sugar and starch content in tuber on fresh weight basis over 20 t FYM ha-1. An application of organics 2 t ha-1 enriched with 6 kg Fe and 4 kg Zn registered significantly higher total chlorophyll content in fresh leaf at 60 DAP, volume of tuber, protein content in tuber on dry weight basis and starch content in tuber on fresh weight basis as compared to no application of Fe and Zn (control).
