Effect of Integrated Use of Farmyard Manure and Chemical Fertilizers on Soil Properties and Productivity of Rice in Chitwan

The effect of sole application farm yard manure (FYM) and combined chemical fertilizers FYM on soil properties growth yield traits rice (Variety: Ramdhan) was studied sandy loam at Rambagh, Chitwan, Nepal from June to November 2019. seven treatments were in a randomized complete block design with four replications: T1: 100% recommended dose inorganic fertilizer (RDIF) (i.e., 100:60:40 NPK kg ha-1); T2: 50% RDIF+ @ 9.9 Mt ha-1; T3: 31.3 T4: 11.05 T5: 19.83 ha-1. results indicated that farmyard found have significant the number effective tillers per m-2 grain rice.
