Abstract/ Executive Summary:

A field experiment was conducted to determine the effects of inorganic fertilizer on growth, yield and economic potential of BJRI Mesta-3. The results indicated significant affect of different NPKS levels on Mesta yield and yield contributing characters over control. The highest fibre (3.10t/ha) and stick (7.20t/ha) yield were obtained by the combination dose of N100 Kg/ha with PKS 10-60-20 kg/ha at Manikganj. The plant height (3.08m), base diameter (20.10mm) also found highest with the same treatment of fertilizer combination. By the same treatment produced higher fibre yield and yield contributing characters at Kishoreganj though that yield was slightly lower than that of Manikganj location. Economic analysis favored the use of 100-10-60-20 kg/ha NPKS for yield of 3.10 t/ha Mesta fibre. Therefore this combination seemed to be optimum for good growth and high potential Mesta production in Bangladesh. Application of modern fertilizer technologies on the mechanized management of Mesta will greatly increase grower profit.

Commodity: Mesta, Fertilizer

Objectives:

Present study was aimed to determine the nutritional requirements of the variety BJRI Mesta-3 (SAMU’93) for its optimum growth and yield.

Methodology:

The study was carried out at the Experimental farms of Bangladesh Jute Research Institute applying randomized complete block design (RCBD) with three replications. A total 10 treatments (T1:N0P0K0S0; T2:N50P5K30S10; T3:N50P10K60S20; T4:N50P15K90S30; T5:N100P5K30S10; T6:N100P10K60S20; T7: 100P15K90S30; T8:N150P5K30S10; T9:N150P10K60S20; T10:N150P15K90S30) combinations along with a control were distributed randomly in each plot. The dimension of unit plots was 3.1 m × 3.1 m having 1m space between the plots, blocks and around the field. There was 20 cm deep drain around each block and plot. At the beginning of the experiment, the land was well prepared and fertilizers were applied as per treatment. Required amounts of chemical 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 days after sowing while all other fertilizers were applied at the time of sowing. Mesta seeds were broadcasted at the rate of 8 kg/ha. All cultural operations were done as and when necessary. The crop was harvested on 120 DAS. After shedding of leaves, the bundles were steeped plot-wise in pond water for 15-20 days for retting and fibre 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), fibre yield (FY) and stick yield (SY). Statistical and economic analyses were also carried out.

Achievement/Findings:

The overall treatments had significant positive impact over control (T1) on growth and yield and quality parameters and effect of combined fertilizers on them were explained. The most important parameter, fibre yield (3.1 t/ha) and stick yield (7.2 t/ha), were recorded highest with T6:N100P10K60S20 treatment. From the results of economic analysis, combination of N100P10K60S20 kg/ha showed higher BCR. Considering all these aspects, specially yield and BCR, T6:N100P10K60S20 kg/ha treatment seems to be the best combination for the yield potential of the Mesta variety BJRI Mesta-3.
