Effect of planting techniques, fertilizer and manure on growth and yield of rice (Oryza Sativa L.) under rice-wheat cropping system in inceptisol

Abstract

A field experiment was carried out at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.) during kharif season of 2017-18 to study the effect of planting techniques, fertilizer and manure on productivity, profitability and soil organic pools in rice (Oryza sativa L.) under rice-wheat cropping system in Inceptisol. The experiment was laid out in split plot design with three replications. The main factor consisted of three planting techniques viz. (T1 - reduced tillage- transplanted rice (RT-TPR), T2 - furrow irrigated raised beds (FIRB), T3 - puddled - transplanted rice (CT-TPR)) and sub factor five nutrient management practices viz. (F1 – Control, F2 - RDF, F3 - 125% RDF, F4 -150% RDF and F5 - RDF+25 kg/ha ZnSO4) as subplot treatment. The soil of experimental site was low in organic carbon and nitrogen and medium in available phosphorus and available potassium and alkaline in reaction. The maximum values of growth characters and yield attributes (plant height, number of tillers, dry matter accumulation, number of panicles, panicle length, grain panicle-1 and test weight) was recorded in P3 (CT- TPR) treatment which remained at par with P2 (FIRB) treatment. Similarly, maximum grains & straw yield, among nutrient management treatments, the maximum values of growth characters, yield attributes, grain and straw yield was noticed with the application of fertilizer as 125% RDF.
