Abstract

The effect of sole application of farm yard manure (FYM) and combined application of chemical fertilizers and FYM on soil properties and growth and yield traits of rice (Variety: Ramdhan) was studied on sandy loam soil at Rambagh, Chitwan, Nepal from June to November 2019. The seven treatments were studied in a randomized complete block design with four replications: T1: 100% recommended dose of inorganic fertilizer (RDIF) (i.e., 100:60:40 NPK kg ha-1); T2: 50% RDIF+ FYM @ 9.9 Mt ha-1; T3: 50% RDIF+ FYM @ 31.3 Mt ha-1; T4: 50% RDIF+ FYM @ 11.05 Mt ha-1; T5: FYM @ 19.83 Mt ha-1. The results indicated that combined application of chemical fertilizers and farmyard manure was found to have a significant effect on the number of effective tillers per m-2 and grain yield of rice. There was no significant interaction between thousand grain weight and sterility percent. The highest grain yield of 3,453.69 kg ha-1 and the highest number of effective tillers per m-2 (299) were found in the application of 50% RDIF+ FYM @ 31.3 Mt ha-1. The application of the highest level of FYM alone improved the soil properties. The highest values of available soil organic carbon (34.67 Mt ha-1), available soil nitrogen (1.24 Mt ha-1), and available soil phosphorus (39.57 kg ha-1) at a depth of 0–15 cm were found with the application of FYM @ 62.5 Mt ha-1. The findings of this study suggest that farmers can apply FYM @ 62.5 Mt ha-1 to improve soil properties and 50% RDIF + FYM @ 31.3 Mt ha-1 to have the higher grain yield of rice.
