Tasnim and M.A. Alim Agronomy division, Bangladesh Jute Research Institute, Manik Mia Avenue, Dhaka, Bangladesh *Corresponding author, Email: oni.abida@gmail.com (Received: 15 January 2023, Accepted: 20 November 2023) Keywords: Fiber crop, Nutrient, growth, fiber yield, olitorius breeding line Abstract The research work was conducted at Jute Agriculture Experimental Station (JAES) Manikganj and Jute Agriculture Regional Station (JARS) Faridpur of Bangladesh. The present study aimed at determining the nutritional requirement for optimum growth and yield of an advanced olitorius breeding line of O-0512-6-2 in Bangladesh. The experiment was laid out in RCBD with 10 treatments having three replications during the year 2019, 2020 and 2021. The results indicated significant effect on yield and yield contributing characters over control with different fertilizer (NPKS) levels of advanced olitorius breeding line of O-0512-6-2. The highest number of plant height, base diameter, green weight with leaves and without leaves was observed by the treatment T3 (N100P10K25S20) which is statistically significant. The highest fiber yield (2.75 t ha−1) and stick yield (6.50 t ha−1) at Manikganj and highest fiber yield (2.58 t ha−1) and stick yield (6.09 t ha–1) at Faridpur was also obtained by the combined dose of N100P10K25S20 (T3) kg ha−1. Therefore, this combination N100P10K25S20 Kg ha−1 seemed to be optimum for maximum growth and yield of advanced olitorius breeding line of O-0512-6-2. Introduction Jute is an eco-friendly and the major cash crop in Bangladesh. Bangladesh produces 33 % of the total worldwide production of jute. Bangladesh's top priority is to improve jute fiber yield and quality. Bangladesh generated jute fiber on an average of 7.45 lakh ha of land per year (BBS, 2021). Jute holds an important position in the industrial sector of the economy of Bangladesh (Islam and Ali, 2017). However, from 2010-2011 and onwards, the area and development grew dramatically as people became more environmentally conscious and shifted to natural fibers to avoid harmful effects of synthetic fibers on the environment. As a result, demand for jute fiber has risen in recent years, both domestically and internationally. Jute fiber is produced mainly from white jute (Corchorus capsularis) and tossa jute (Corchorus olitorius). Demand of jute fiber is being increased in the recent years both in home and abroad (Islam and Ali, 2018). Jute fiber is used to make many different sorts of bags, wools, ropes, sacks, and coverings. The superior quality jute fiber is used for making carpets, twine, curtains, cloth etc. Jute sticks, the byproduct, are used as fuel, fencing and raw materials for paper pulp and hardboard. Jute leaves, which are high in vitamins, carotenoids, calcium, potassium, and dietary fibres, are used in soups and folk medicine to cure fevers, chronic cystitis, colds, and tumours. Aside from its diverse uses, cultivation of this crop improves soil fertility by supplying a large quantity of green biomass through leaves, twigs, and thinned out plant, which includes a significant number of macro and micro nutrients (Singh et al., 2015). Bangladesh jute research institute (BJRI) has been developed some tossa varieties/ strains. The importance of macronutrients (N, P, K and S) on the growth, yield and quality of fiber crops is well established. Judicial application of NPK and S may increase the yield of a variety. The importance of N, P, K and S on the growth, yield and quality of fiber crops is well established (Ali et al., 2017a, 2017b). Balanced nutrition is a crucial component of developing plants and comprises providing the plant with enough of the vital minerals N, P, K, Mg, Ca etc. (Senjobi et al., 2013). Determination of nutrients rate for the new varieties/ strains are also pre-requisite for final release. Yet this fertilizer plays an 2 Sultana et al. important role to increase the fibre growth and yield. It is necessary to find a fertilizer combination which is economically profitable and at the same time gives maximum yield and yield potential. So, an experiment has been undertaken to observe the effects of macronutrients (N, P, K and S) on growth, yield and quality of the advanced tossa jute breeding line O-0512-6-2. Materials and Methods In Bangladesh, the experiment was carried out at Jute Agriculture Experimental Station (JAES) Manikganj and Jute Agriculture Regional Station (JARS) Faridpur of Bangladesh during 2019- 2021. The experiment was laid out in randomized complete block design (RCBD) with 10 treatments of NPK and S (Kg ha⁻1) having three replications. Total 10 treatments combination along with a control distributed randomly in each plot as one replication. The dimension of unit plot was (2.1 m×2 m) having 1 m space between plots, blocks and around the field. There was 20 cm deep drain around each block and plot. The land was well prepared and fertilizers were applied as per treatments. The following treatments combinations were used in the experiment: T1: N0P0K0S0 T6: N100P15K30S30 T2: N75P10K25S20 T7: N100P15K30S40 T3: N100P10K25S20 T8: N100P20K30S20 T4: N125P10K25S20 T9: N100P20K30S30 T5: N100P15K30S20 T10: N125P20K35S40 Required amount of N, P, K and S fertilizers were applied in the form of urea, TSP, MoP and gypsum. The experiment was sown on first week of April and harvested first week of August. Half urea and total amount of TSP, MoP and gypsum were incorporated to the experimental plot as per treatment design at the time of final land preparation. Remaining half of urea was top dressed at 45 days after sowing (DAS). Table 1.

Plant population, plant height, base diameter, green weight with leaves, green weight without leaves, fiber yield and stick yield were recorded from each plot. All collected data were analyzed statistically following the ANOVA technique and the means were adjusted by DMRT (Gomez and Gomez ,1984). Results and Discussion Nitrogen, phosphorus, potassium and sulfur are the main essential macronutrients for most of the biological process in a plant. Their individual effects and interactions on fiber plants were showed in many studies (Maity et al., 2007). Fiber yield and yield contributing characters were affected by different treatment combinations. This experiment used 10 treatment combinations. Nutrient requirement of advanced breeding line for maximum growth 3 In Manikganj, the highest plant height (3.04 m), base diameter (17.42 mm), green weight with leaves (39.02 t ha−1) and green weight without leaves (35.81 t ha−1) were observed with the application of treatment T3 (N100P10K25S20). (Table 3) Significant effect of increasing dose of fertilizer application on fiber yield and stick yield was also observed. Table 3.

The highest fiber yield (2.58 t ha−1) and stick yield (6.09 t ha−1) which was statistically significant and obtained by treatment T3 (N100P10K25S20) (Fig. 3, 4). So, the combined dose of NPK and S 100-10-25-20 kg ha−1 is a suitable dose for the cultivation of advanced breeding line O-0512-6-2 for maximum growth and production. These results are strongly supported by the previous research results (Sarker et al., 2000; Ali et al., 2017). 0 1 2 3 4 5 6 7 8 T1 T2 T3 T4 T5 T6 T7 T8 T9 T10 St ic k yi el d (t ha −1 ) Treatments Nutrient requirement of advanced breeding line for maximum growth 5 Fig. 3.

Conclusion The use of combined chemical fertilizers had a considerable favorable impact on all yield contributing characteristics as well as yield. The present study revealed the positive impacts of combined dose of NPKS on the fiber yield and yield component of advanced olitorius breeding line O-0512-6-2 in both locations. The combined dose of N100P10K25S20 is a suitable dose for the cultivation of advanced olitorius breeding line of O-0512-6-2 in Bangladesh. References Ali, M.S., M.M. Hoque, M.N. Gani and M.M.
