Effect of integrated nutrient management on soil property and nutrients uptake by Rice (Oryza sativa L.)

Abstract

The present investigation entitled “Effect of integrated nutrient management on soil property and nutrients uptake by Rice (Oryza sativa L.)” was conducted at Genetics and Plant Breeding Research Farm of Acharya Narendra Deva University of Agriculture and Technology Kumarganj, Ayodhya, during Kharif season 2018. The results revealed that among the INM practices application of 100% RDF alone significantly improve the protein content, N, P, K uptake by rice crop and maximum increase in soil properties like available nitrogen (115.40 to 126.30 kg/ha.), phosphorus (15.60 to 16.80 kg /ha.), potassium (240.0 to 258.00 kg/ha.).There is significantly decline in pH (9.0 to 8.70), Electrical conductivity (0.96 to 0.83 dSm1) and maximum build-up of organic carbon (0.23 to 0.30%), of soil in combined application of 50% RDF + 50% N through green manure (Dhaincha).
