Abstract: A field trial was conducted to evaluate the role of boron (B) application at different growth stages in improving the growth, yield and net economic return of rice at farmer’s fields during summer season, 2009. Boron was soil applied (1.5 kg/hm2) at the transplanting, tillering, flowering and grain formation stages of rice; foliar applied (1.5% B solution) at the tillering, flowering and grain formation stages of rice, and dipped seedling roots in 1.5% B solution before transplanting; while control plots did not apply any B. Boron application (except dipping of seedling roots in B solution, which caused toxicity and reduced the number of tillers and straw yield than control) substantially improved the rice growth and yield. However, soil application was better in improving the number of grains per panicle, 1000-grain weight, grain yield, harvest index, net economic income and ratio of benefit to cost compared with the rest of treatments. Overall, for improving rice performance and maximizing the net economic returns, B might be applied as soil application at flowering.
