Enhancing Yield and Yield Components of BARI Sarisha-14 and BARI Sarishaa-15 through Boron Fertilization

Boron is an essential micronutrient for mustard that plays important roles in growth, development as well as yield of mustard. A field experiment was conducted at the Agronomy Field Laboratory of Bangladesh during November through January to study the effect of boron fertilizer on the yield of mustard two varieties in T. aman rice- Mustard- Boro rice cropping pattern. The experiment consisted of two factors- Factor A: Two mustard cultivars viz., BARI Sarisha-14 and BARI Sarisha-15 and Factor B: Four levels of boron viz., 0 kg boron ha-1 (control), 0.5 kg boron ha-1 (50% of RD), 1.0 kg boron ha-1 (100% of RD) and 1.5 kg boron ha-1 (150% of RD). The experiment was laid out in a randomized complete block design with three replications. Results reveal that yield and yield contributing characters were not significantly influenced by studied two mustard varieties except plant height. Numerically the higher seed yield was recorded from the variety BARI Sarisha-14. In case of level of boron application, the highest seed yield was obtained with the application of 1.0 kg boron ha-1 (100% of RD) which was followed by application of 1.5 kg boron ha-1 (150% of RD) and the lowest seed yield of mustard was recorded in control treatment (no boron application). From the interaction, it is observed that BARI Sarisha-14 with 1.0 kg boron ha-1 (100% of RD) produced the highest seed yield which was statistically similar with BARI Sarisha-15 with 1.0 kg boron ha-1 (100% of RD). From the results of the study, it may be concluded that BARI Sarisha-14 or BARI Sarisha-15 with 1.0 kg boron ha-1 (100% of RD) could be cultivated for obtaining highest seed yield of mustard in T. aman rice-Mustard-Boro rice-based cropping pattern.
