| Abstract | ||||
| The intercropping system stands as a prevalent strategy for augmenting crop yield. To test the mentioned system, a study was conducted to evaluate the impact of intercropping systems and mungbean sowing time on upland rice using the NSIC Rc27 variety under different mungbean sowing times. The experiment was laid out in Randomized Complete Block Design (RCBD) using a split-plot arrangement with three replications, intercropping systems were distributed in the main plots while the sowing time of mungbean plants was arranged in sub-plots. Results showed that the tested factors and their interaction did not have significant effects on leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR), and yield components for both upland rice and mungbean. On the other hand, notable variations were observed in weed parameters, agronomic characteristics, and grain yield of both crops. Monocropping and early mungbean sowing time (14 days before upland rice establishment) led to early flowering but delayed maturity in upland rice. The land and area-time equivalent ratios were greater than one, indicating that both crops can be grown together, wherein simultaneous planting was the most effective treatment. The intercropping scheme resulted in a lower weed population. Monocropping upland rice yielded a net profit of PhP38,425 while intercropping with mungbean 14 days before upland rice establishment resulted in a higher net profit of PhP70,325. Similarly, monocropping mungbean yielded PhP197,175.00 while intercropping with upland rice 14 days earlier produced the highest net profit of PhP283,575. | ||||
