Performance of Three Varieties of Hybrid Rice Under Rainfed and Irrigated Ecosystem




Rice cultivation is one of the major sources of income in the Philippines, especially in rural areas. This study was conceptualized to help the government and the farmers determine the suitability of hybrid rice in a rainfed ecosystem. This study also aims to evaluate the performance of three varieties of hybrid rice in rainfed and irrigated ecosystems such as Pioneer 73 (V1), Pioneer 77 (V2), and Pioneer 81 (V3). The experiment was laid out in a Randomized Complete Block Design (RCBD) involving two factors. Factor A was the ecosystem that was observed as rainfed ecosystems and irrigated ecosystems. Factor B was the different varieties. The total experimental area was divided into six blocks representing the treatments. There are four plots in every block to represent the treatments that were replicated four times. T-test results in both conditions reveal no significant differences, which means that Pioneer 73, 77, 81 could be grown in rainfed areas and can give the same yield as the irrigated ecosystem. It also showed that a significant difference was observed mostly in irrigated. A study using hybrid should be conducted to prove the reliability of the hybrid varieties tested that may contribute to the increase of yield and sustainable production. Based on the results of the study, it was found that the three hybrid varieties, Pioneer 73, 77, and, 81 can thrive in the rainfed ecosystem. It was also observed that sufficient water leads to an increase in yield whether the field is irrigated or rainfed. Late detection for the leaf blight infection for Pioneer 73 contributes a certain percentage of yield loss.
