Preliminary yield and growth performance of rice (var nsic rc222) applied with Bacillus spp. based bio-fertilizer
Abstract
This study aimed to find out and document the performance of NSIC Rc 222 rice variety as influence by application of Bio-fertilizer. Particularly, it aimed to find out the determine the growth and yield performance of the rice applied with bio-fertilizer at 10 days after first application, and to determine the profitability of NSIC Rc 222 rice variety . The study was conducted from July to December 2025 in Barangay Antonino, Balaoan, La Union to evaluate the performance and profitability of NSIC Rc 222 rice applied with a Bacillus-based biofertilizer at 10 days after transplanting (DAT). Using a Randomized Complete Block Design (RCBD) with three replications and following the PalayCheck system, standard soil analysis, fertilizer recommendations, crop establishment, irrigation, and integrated pest management practices were implemented to ensure reliable results. Biofertilizer application at 10 DAT significantly increased panicle length and the number of filled grains, indicating improved grain filling and overall yield performance. Although reductions in unfilled grains and slight differences in 1000-grain weight were observed, these were not statistically significant. The treatment also enhanced vegetative growth and tiller productivity, suggesting that early application supports better crop establishment and development. Economically, despite higher production costs, the 10 DAT treatments generated higher gross and net income, resulting in the highest return on investment among the treatments. Early application of Bacillus-based biofertilizer at 10 DAT proved to be the most agronomically effective and financially viable strategy for improving the productivity and profitability of NSIC Rc 222 rice.
