Effect of integrated nutrient management on productivity of rice (Oryza Sativa l.) and soil fertility status under rainfed condition of Meghalaya

The front line demonstrations were conducted at the farmers’ field to demonstrate the organic sources of nutrients for maintaining the soil health, reducing the rate of chemical fertilizer and to increase the yield of rice (Oryza sativa L). The demonstration was conducted at ten farmers’ field covering 6 ha. of land at RiBhoi District of Meghalaya during the year 2017-2018 and 2018-2019. The results of the study revealed that the application of Azospirillum @3.5kg/ha + PSB @3.5kg/ha + 30 kg of cow-dung by root dip treatment along with 50% recommended dose of chemical fertilizers had recorded significantly higher yield i.e. 45.72 q/ ha with B.C ratio of 2.43 followed by farmer’s practice (24.6 q/ha yield with B.C ratio 1.62). Moreover, the soil nutrient status was also improved at the time of harvesting as compared to farmer practice in both the years. An extension gap of 21.12 q/ ha and technology index 8.56 had been recorded.
