Abstract:

In rice farming, farmers aim to plant a variety that could help them increase their yield, but some factors that could contribute to a higher production were not practiced. Genetic and agronomic factors are associated with changes in crop yield over time. This study was conceptualized to test the reliability of planting distance and planting density in the yield of NSIC Rc 160 rice variety. Planting distance is one of the many factors that affect the yield of crops. The right distance may contribute to an optimum yield and easy manipulation of field activities, such as cultivation, weeding, fertilizer application, and others. Right spacing and planting density will lead to an increase in yield. To prove the reliability of these factors, a planting distance between hills and rows was utilized in the study (25x25, 20x20, 20x15, and 15x15). The study was laid out using a Randomized Complete Block Design (RCBD) and statistically analyzed using Analysis of Variance (ANOVA). Scheffe was used to test the significant difference between treatment means. Results revealed that planting distance of 25x25cm had the highest performance and significantly affected the initial height, final height, productive tillers, filled grains per panicle, and yield. It also shows that higher planting density results in more or high unfilled grains in terms of unfilled grains. Grains unfilled were due to the strong competition of the plants absorbing available nutrients from the soil. Across all treatments and parameters used, it is strongly recommended to use a 25x25 cm planting distance. To prove the result and accuracy of the study, similar research for verification could be conducted.
