Abstract :

The present study was conducted to investigate the effects of Magnesium (Mg), Zinc (Zn), and Boron (B) on the growth and fiber yield of BJRI Tossa Pat-8, a prominent jute variety, under varying nutrient levels. The experiment was carried out at two different locations, Kishoreganj and Manikganj, in 2023, using a Randomized Complete Block Design (RCBD) with three replications. The results showed that the application of Mg, Zn, and B in combination with Recommended Dose of Fertilizers (RDF) significantly enhanced growth parameters and yield-contributing traits when compared to the control treatment. The highest fiber yield of 2.57 t/ha and stick yield of 5.14 t/ha were observed at Kishoreganj with the treatment T7 (RDF + 4Zn + 3B + 10Mg), while at Manikganj, the highest fiber yield of 2.78 t/ha and stick yield of 5.83 t/ha were achieved under the same treatment. These results indicate that the combination of 4Zn + 3B + 10Mg significantly improved both fiber yield and stick yield, along with other key growth parameters such as plant height, base diameter, and plant population, as compared to the control and other treatment combinations. The study demonstrates that the application of zinc, magnesium, and boron plays a crucial role in optimizing BJRI Tossa Pat-8 growth, contributing to improved fiber quality and overall biomass production. Based on these findings, the combination treatment T7 is recommended as an optimal nutrient regimen for maximizing the growth and productivity of BJRI Tossa Pat-8, thereby ensuring better fiber yield and sustainability in jute cultivation. The findings also suggest the need for further research to refine micronutrient management for long-term crop productivity and soil health.
