The effect of different organic and inorganic fertilizers had a significant effect on the yield of spring rice. A field experiment was carried out to determine the effects of different organic and inorganic fertilizers on the yield of spring rice var Hardinath-1 at Siranchowk rural municipality-4, Gorkha during the spring season of 2021 with four replications and five treatments: T1[Recommended inorganic fertilizer Nitrogen, Phosphorous, and Potassium (@100:30:30 kg/ha)], T2[75% recommended inorganic fertilizer + 25% recommended organic fertilizer: i.e. (Farm Yard Manure (6 ton /ha)], T3(50% recommended inorganic fertilizer + 50% recommended organic fertilizer), T4(25% recommended inorganic fertilizer + 75% recommended organic fertilizer ), and T5 (Recommended organic fertilizer) using simple Randomized Complete Block Design with 3*3 m of individual plot size. A biometrical observation like plant height (95.33 cm), and the number of tillers (340.75/ m2) were found significantly highest on T2. Similarly, yield attributing characteristics like the number of effective tillers (315.75/m2), several filled grains per panicle (150.25), and highest panicle length (25.06 cm) were also significantly highest on T2. The highest grain yield (8.27 ton/ha), straw yield (12.14 ton/ha), and harvest index (0.40) were also observed on T2. Total net return was found highest on T2: 287330 Nepalese Rupees(NPR) incurring the cost of fertilizer Rs NPR 18940 per hectare returning the gross return of NPR 268390 per hectare. In conclusion, T2 was the best combination of other biofertilizer combinations. So, the spring rice productivity can be enhanced via the adoption of 75% recommended inorganic fertilizer + 25% recommended organic fertilizer in fertilizer management practice at Chorkate, Gorkha.
