Optimizing Seed Production: The Impact of NPKSZn and B on the Advanced Breeding Line KBL-155 (1)

The need for optimized nutrient management in kenaf cultivation is crucial to enhance seed production and overall yield. The present study was conducted to determine the influence on nutrients of N, P, K, S, Zn and B on the advanced kenaf breeding line KBL-155(1) for seed production. The jute agriculture experimental station in Manikganj served as the site of the experiment in 2022 followed by RCBD design with three replications. The results indicated significant differences among treatments in all measured parameters. The yield and yield contributing characteristics over control were impacted by N rates, according to the results. N 100 kg/ha (T₉) generated the most for the seed (0.879 t/ha), in Manikganj. The dose P 15 & 20 Kg/ha added optimal output of seed. The level of 30, 40 kg K/ha gave the highest seed yield. The dose 20, 30 kg S/ha showed significantly the highest seed return and output enhancing qualities. All the yield contributing factors are affected by the different nutrient element shown in tables. The results implied that the joint dose of N₁₀₀P₁₅K₃₀S₂₀ & N₁₀₀ P₂₀ K₄₀ S₃₀ kg/ha is potentially considered in providing the advanced kenaf breeding line KBL-155(1) for seed production. Moreover, it is also revealed that T₉ treatments are more economical proper fertilizer dose for seed production. In conclusion, the application of balanced nutrient management, particularly N₁₀₀P₁₅K₃₀S₂₀Zn₂B₂ and N₁₀₀P₂₀K₄₀S₃₀Zn₃ B₃, significantly enhanced the yield and yield-contributing factors of KBL-155, making it a promising candidate for high productivity in the agroecological zone of Manikganj. Further studies are recommended to confirm these findings and optimize fertilizer use for better yield performance.
