Integration Effect of Organic and Inorganic Nutrient Sources on Nutrient uptake of Potato and Soil Properties in Alluvial Plains of Northern Bihar

Abstract

A field experiment was conducted to study the response of potato (Solanum tuberosum L.) to integrated nutrient management with variety Kufri Ashoka. Treatments consisted of five levels of RDF (0, 75, 100, 125, 150%) and two sources of organic manures (farmyard manure @ 20.0 t/ha and spent mushroom substrate @ 4.0 t/ha).The results revealed that there was a significant difference in various plant growth and yield parameters like growth, yield attributes and fresh yield of tubers, total nutrient uptake, the protein content of tuber and the fertility status of the post harvested soil. Application of 100 % RDF coupled with FYM 20 t/ha or SMS 4 t/ha had performed well, found statistically at par to treatments, 125% RDF and 150% RDF integrated with FYM 20 t/ha or SMS 4 t/ha respectively.
