Excessive and inappropriate chemical fertilizer application has led to a decline in soil fertility, productivity, and microorganisms. Organic fertilizers retain their soil quality, nutrient availability, and environmental conditions. A field experiment was carried out to study the effect of Farm Yard Manure (FYM), Vermicompost, and biofertilizer on the growth and yield of chili (Namdhari–1701) at Barju–5, Sunsari, Nepal, from March 2024 to June 2024. A single–factor Randomized Complete Block Design (RCBD) was used to set up the experiment comprising seven treatments (Control, FYM @ 25 t.ha-1, Vermicompost @ 2.5 t.ha-1, Vermicompost (50 %) + FYM (50 %), Mycorrhiza1 @ 25 kg.ha-1, Mycorrhiza1 (50 %) + FYM (50 %), Mycorrhiza2 @ 35 kg.ha-1) with three replications. The study revealed that the FYM, Vermicompost + FYM, and Mycorrhiza1 + FYM treatments resulted in the highest total grain y...

A field study was conducted at a farmer’s field in Ratuwamai, Morang, from February 2023 to June 2023 to assess the impact of various bio-fertilizer sources on the growth and yield characteristics of rice. The experiment followed a randomized complete block design (RCBD) with three replications and seven treatments. The treatments included: T1: Recommended NPK dose (100:30:30 kg/ha), T2: Farmyard manure (FYM) (12 t/ha), T3: Goat manure (8 t/ha), T4: Mycorrhiza (11.25 kg/ha), T5: Organic manure (11.25 kg/ha), T6: Mustard seed cake (3.75 t/ha), and T7: Control (no fertilizer). Our investigation explored the significant effects of these treatments on the growth and yield-contributing attributes of the Chaite-4 rice variety. Results indicated that T1 (7021.47 kg/ha) and T2 (6681.70 kg/ha) exhibited the highest grain yield, followed by T3 (5128.35 kg/ha), T2 (4482.78 kg/ha), T5 (4335.79 kg/...
