Abstract/ Executive Summary:

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 N100 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 N100P10K60S20 kg/ha. The findings of the present experiment clearly indicated a great prospect of nutrient combination of N100P10K60S20 kg/ha on the growth and yield of fibre production on the variety BJRI kenaf-4.

Program Area: Crop-Soil-Water Management

Commodity: kenaf, Fertilizer

Objectives:

Ion of its fertilizer requirement is very important. Therefore, the present study has been undertaken to observe the effects of N, P, K and S fertilizers on the growth and yield of the pre-released Kenaf variety, BJRI Kenaf-4 and to find out the finest requirement of nutrients combination to obtain highest fibre production.

Methodology:

The experiment was set up at the Jute Agricultue Experimental Station (JAES) of BJRI, Jagir, under Sadar Upazila of Manikganj district and Regional Station, Kishoreganj of BJRI. The experiment was laid out in randomized complete block design (RCBD) with three replications. A total 10 treatment combinations along with a control were distributed randomly in each plot as one replication. The dimension of unit plots was 3 m × 3 m having 1 m space between the plots, blocks and around the field. There was 20 cm deep drain around each block and plot. Each replication was divided into 10 unit plots. At the beginning of the experiment, the land was well prepared and fertilizers were applied as per treatment. Required amounts of N, P, K, S fertilizers were applied in the form of urea, TSP, MoP and gypsum. Urea was applied in two splits: half amount was applied at sowing and the rest half was top dressed at 45 DAS (days after sowing) while all other fertilizers were applied at the time of sowing. Kenaf seeds were broadcasted at the rate of 12 kg/ha. All cultural operations were done as and when necessary. The crop was harvested when 80% of the plants showed the sign of maturity. After shedding of leaves, the bundles were steeped plot-wise in pond water for 15-20 days for retting and fiber was extracted. At harvesting time, six plants were selected at random from each plot and tagged in the field to note plant height (PH), base diameter (BD), fiber yield (FY) and stick yield (SY).

Achievement/Findings:

Each and every one of the treatments influenced on growth and yield. Among the treatment combination N100P10K60S20 kg/ha (T6) treatment performed best for the most valuable yield parameters fiber and stick yield. We found highest benefit cost ratio from economic analysis and it was originated by the nutrient combination of N100P10K60S20 kg/ha. Bearing in mind all these aspects, especially yield and economics, T6 (N100P10K60S20 kg/ha) treatment seems to be the best combination for fibre production of this variety (BJRI Kenaf-4).
