Abstract: The effect of fertilization and planting density was determined on the yield of two varieties of fine rice cv. Kalizira and Badshabhog. Three different planting densities namely, 15cm x 10cm, 20cm x 12cm and 25cm x 15cm and four doses of fertilizer combination (N- P- K- S- Zn) namely 0-0-0-0-0, 20-15-11.25-7.5-1.25, 40-30-22.5-15-2.5 and 80-60-45-30-5 kg ha–1 were applied. Badshabhog was found significantly superior to Kalizira for number of grains panicle–1,1000- grains weight, grain yield and harvest index. Both the varieties performed best at 20cm x 12cm spacing and both of them also showed the highest response at 40-30-22.5-15-2.5 kg ha –1 N- P- K- S- Zn. There was consistently significant increase in grain yields up to 40-30-22.5-15-2.5 kg ha –1 N- P- K- S- Zn, beyond which the yields of both the varieties declined.
