Assessing the Growth and Productivity of Rice Under Different Fertilizer Management Practices Grown Under Sri Production in Kavre, Midhill of Nepal

Abstract

A field experiment was conducted during rainy season of 2016 to evaluate the effect of different fertilizer management practices on growth and productivity of rice grown under SRI system in Kavre district at farmers’ field. The experiment was laid out in Randomized Completely Block Design involving seven different fertilizer management practices viz. Nutrient Expert Rice recommended chemical fertilizer (NPK), FYM (Farm Yard Manure), TP (Titepati), SOM (Shakti organic manure), GM (Goat manure), UD (Urine Drenching) and FFP (Farmers Fertilizer Practice) with four replications. The result revealed significant difference in terms of plant height, panicle length, filled grains panicle-1, grain and straw yields and sterility%. The highest grain yield (5.28t ha-1), straw yield (9.710t ha-1), effective tiller m-2 (210.8), panicle length (24.23cm), number of filled grains panicle-1 (81.37) and the lowest sterility % (23.82%) were obtained from chemical fertilizer followed by Titepati, FYM, FFP, SOM, UD and the lowest grain yield (2.91t ha-1), straw yield (4.46t ha-1), effective tiller m-2 (130.5), panicle length (21.90cm) and number of filled grains panicle-1 (48.77) were obtained in goat manure and concluded that NE-Rice recommendation is the best followed by green manuring of Titepati in intensified rice production of mid-hill agro-eco zone of central Nepal.
