Basmati rice performance as influenced by application timing of organic N sources

Abstract

Field experiments were conducted during 2019 and 2020 at the Crop Research Centre, Sardar Vallabhbhai Patel University of Agriculture and technology, Meerut, Uttar Pradesh. The experiment consisted of 14 different treatments replicated thrice in a randomized block design. Soil of the experimental field was sandy clay loam in texture, neutral in reaction with low in available nitrogen, medium in available phosphorus and potassium. Result on pool basis reveal that highest growth and yield attributes parameters, viz. plant height (97.04 cm), effective tiller (225.22/m2), panicle length (30.67 cm), grain weight (1.77 g/panicle), filled grains/panicle (82.18), test weight (28.50 g) along with biological yield 108.24 q/ha and grain yield 40.78 q/ha were recorded with the application of 25% recommended N through dhaincha incorporated on planting date + rest N through chemical fertilizer followed by application of 25% recommended N through vermicompost incorporated 10 day before transplanting + rest N through chemical fertilizer.
