Unearthing the Impact of Diverse Nutrient Sources on Soil Quality in Transplanted Rice in Eastern U.P., India

Abstract

A field experiment was conducted at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.) during Kharif season 2022 to assess the effect of different nutrient sources on physico-chemical properties of randomized block design and replicated three times with seven treatment combinations in rice crop. The treatment combinations were T1:-Control, T2:-100% RDF, T3:-75% RDF + 25% N through Vermicompost+ Jeevamrit application at 30 DAT (Days after transplanting),T4:-75% RDF+25%N through FYM+ Jeevamrit application at 30 DAT, T5:- 50% RDF+50% N through Vermicompost + Jeevamrit application at 45 DAT, T6:-50% RDF+50%N through FYM + Jeevamrit application at 45 DAT and T7:-50% RDF+25% N through Vermicompost +25% N through FYM + Jeevamrit application 30 and 45 DAT. Rice variety NDR- 2065 was taken as test crop. After harvesting soil was tested for physico- chemical parameters, according to which T5 showed maximum available nitrogen, phosphorus and potassium, in a similar way T5 also showed improved E.C., pH, organic carbon as well as bulk density and particle density.
