Abstract:The present study was conducted to clarify the fertilizer requirement on the growth and yield of the variety Bangladesh Jute Research Institute Kenaf-4. Consequently the experiment was conducted in Jute Agriculture Experimental Station, Manikganj and Jute Research Regional Station, Kishoreganj of Bangladesh Jute Research Institute. The results indicated significant effect of different NPKS levels on Bangladesh Jute Research Institute (BJRI) Kenaf-4 yield and yield contributing characters over control. The highest fibre (3.14t/ha) and stick (7.65t/ha) yield were obtained by the combination dose of N 100 Kg/ha with PKS 10-60-20 kg/ha at Kishoreganj. The plant height (3.14m), base diameter (19.47mm) also found highest with the same fertilizer treatment combination. By the same treatment produced higher fibre yield and yield contributing characters at Manikganj though that yield was slightly lower than Kishoreganj. Economic analysis suggested the best combination is N 100 P 10 K 60 S 20 kg/ha. The findings of the present experiment clearly indicated a great prospect of nutrient combination of N 100 P 10 K 60 S 20 kg/ha on the growth and yield of fibre production on the variety BJRI kenaf-4.
