Popis: Background: Replenishing the lost nutrients through the use of various soil amendments is vital in order to maintain soil fertility for sustained productivity in jhumlnd. Integrated Nutrient Management, can boost the upland rice productivity in jhumland by building up the lost soil nutrients. Methods: The study was conducted to evaluate the impact of integrated nutrient management on growth and yield of upland paddy (Oryza sativa L.) in Lai-Lad, Jirang Block of Ri-Bhoi District, Meghalaya, India; during 2019 and 2020. Randomised block design with 12 treatments was applied for the trial with 3 replications. Result: Application of 100% recommended doses of fertilizers + farmyard manure + Azospirillum lipoferum + phosphorus solubilizing bacteria + potassium mobilising bacteria + Glomus + zinc solubilizing bacteria (T10) significantly increased plant growth in both years of cultivation. Grain yield, harvest index and benefit cost ratio of upland paddy were at par among the treatments and were higher in 2nd cropping year. Integrated nutrient management could increase the growth characters, maintain sustained yield and economic profitability of upland paddy in hilly terrains of north-east India, under jhum cultivation.
