Improvement of soybean growth and yield by foliar urea and boron application
Abstract
The experiment was carried out to investigate the effect of foliar urea and boron application on soybean and it was laid out in split-plot design with two soybean varieties (BARI Soybean-5 and BARI Soybean-6) and five foliar application viz. Control (Recommended dose of fertilizer), RDF+ Foliar Spray of water at flower initiation, RDF+ Urea (2%) FS at FI, RDF+ Boron (1%) FS at FI, and RDF+ Urea (2%) + Boron (1%) FS at FI. Results obtained from the experiment showed that the variety, BARI Soybean-6 gave maximum plant height (47.13 cm), dry weight plant-1 (11.55 g), nodules plant-1 (21.27), pods plant-1 (57.47), seeds pod-1 (2.87), 100 seed weight (13.41 g) and seed yield (2.13 t ha-1) compared to BARI Soybean-5. In terms of foliar urea and boron application, highest plant height (48.82 cm), dry weight plant-1 (12.18 g), nodules plant-1 (21.79), pods plant-1 (59.67), seeds pod-1 (2.89), 100 seed weight (13.45 g), seed yield (2.17 t ha-1) and stover yield (2.73 t ha-1) were obtained from treatment T5 (RF+ Urea (2%) + Boron (1%) FS at FI, indicating its effectiveness in enhancing soybean growth and yield. Specifically, the combination of BARI Soybean-6 with treatment T5 demonstrated the most promising results overall, suggesting it as the recommended approach for improving soybean yield in cultivation practices.
