Nutrient requirement has been optimized for the cultivation of advanced breeding line BJC-5050 in Bangladesh. Different nutrient levels influenced the yield contributing characters which ultimately increased the fibre and stick yield over control. Among the nitrogen doses, the rate 100 kg N/ha demonstrated significantly tallest plant (3.17m), highest base diameter (17.34 mm), fibre (2.81 t/ha) and stick (7.06 t/ha) yield. The highest yield of fibre and stick were found with the dose of 15 kg P/ha. The K level up to 45 kg/ha influenced the yield and yield contributing characteristics over the control. The tallest plant was found with 30kg K/ha which was statistically identical the treatments other than treatments of T1, T2 ,T5, and T9. The significant highest fibre yield was induced by K 30kg/ha. In case of S results showed significant yield increase with different rates over the control. It indicates that 20kg S/ha is enough in producing highest yield of fibre and stick. Study revealed that combined dose of NPKS 100-15-30-20 kg/ha may be a suitable dose for the cultivation of advance breeding line BJC-5050.
Fiber yield step up and quality of jute is the prime need of Bangladesh. Jute fibre was produced annually from an average area of 4.50–5.00 lakh ha of land in Bangladesh . But the area and production was increased significantly from 2010-2011 and onwards due to developing more conscious about environment and stepping forward to the natural fibre by escaping from the perilous impact of synthetic fibre to the environment. As a result demand of jute fibre is being increased in the recent years both in home and abroad. In this aspect, research regarding development of new high yielding variety of jute and determination of its fertilizer requirement is very important. In actual fact, these requirements vary within the same type of crop. For example, fertilizer requirement of capsularis line is lower than that of olitorius. The importance of N, P, K and S on the growth, yield and quality of fiber crops is well established [2-12]. It is necessary to find a fertilizer combination which is economically profitable and at the same time gives yield very close to maximum yield potential. Therefore, much attention should be given towards the improvement of yield and quality of jute fiber to bring back the past glory of Bangladeshi jute. Considering the above facts the present study has been undertaken to observe the effects of N, P, K and S fertilizers on the growth, yield and quality of the advance breeding line, BJC-5050 and to find out the optimum requirement of all of these nutrients to achieve the maximum yield potential of this new advance breeding line, BJC-5050.
MATERIALS AND METHODS
The research was carried out at the Jute Agricultural Experimental Station (JAES) of Bangladesh Jute Research Institute, under Sadar Upazila of Manikganj district. The experiment was laid out in randomized complete block design with three replications. A total 10 treatment combinations along with a control were distributed randomly in each plot as one replication (Table 1). The dimension of unit plots was 3.1 m × 3.1 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 and the total land required of 13.3 m × 42 m. At the beginning of the experiment, the land was well prepared and fertilizers were applied as per treatment.
Combined chemical fertilizers demonstrated significant positive effect on all the growth parameter like plant height (Figure 1), base diameter (Figure 2). The maximum plant height (3.17 m), base diameter (17.34 mm) were found by the treatment T6 (N100P15K30S20kg/ha). Application of different treatments showed statistically significant positive effect on fibre yield (FY) and stick yield (SY) of jute. Highest FY (2.81 t/ha) and SY (7.06 t/ ha) were reported with T6 (N100P15K30S20kg/ha) treatment.
Effect of Nitrogen
Yield contributing characters were influenced by nitrogen levels which ultimately increased the fibre and stick yield over control. Among the nitrogen doses, the rate 100 kg N/ha demonstrated significantly tallest plant (3.17m), highest base diameter (17.34mm), fibre (2.81t/ha) and stick (7.06t/ha) yield. The dose of 100kg N/ha might be an effective dose for producing BJC-5050.
Effect of Phosphorus
Different P rates influenced to plant height, base diameter, yield of fibre and stick over control. The highest yield of fibre (2.81t/ha) and stick yield (7.06t/ha) found with the dose of 15 kg P/ha. Results exposed that the dose of 15 kg P/ha will be sufficient to grow BJC-5050.
Effect of Potassium
The tallest plant (3.17m) was found with K 30 kg/ha (T7 ) which was statistically similar with T3, T4, T7, T8, and T10,. Significantly highest fibre yield was induced by K 30Kg/ha (2.81t/ha). Taking into consideration the findings that the dose of K 30 kg/ha will be a sufficient to produce the advance breeding line BJC-5050 . Study revealed that the advance breeding line BJC-5050 needs lower amount of K.
Effect of Sulfur
Different rate of S result showed significant increased on the yield and yield contributing characters over control. Study revealed that 20kg S/ha is enough in producing highest yield of fibre and stick. The combination dose of N100 P15 K30 S20 kg/ha may be enough for the advanced breeding line BJC-5050.
The preeminent FY and SY were found with the combination of N100 P15 K30 S20 kg/ha. These results are strongly supported by the previous research results [2-5, 7].
It could be concluded that combined dose of NPK and S 100-15-30-20 kg/ha would be a suitable dose for the cultivation of advanced breeding line BJC-5050. The study evolved a technology which ultimately recommendation of fertilizer (NPK & S 100-15-30-20 Kg/ha) for the advance line BJC-5050.
