When the Fields Heat Up: Quantifying the Effects of Temperature and Rainfall on Sugarcane Yield in Bais City, Negros Oriental
Keywords:
Sugarcane yield, Rainfall, Temperature, Climate variability, Quantitative analysisAbstract
This study examines the effects of climatic factors on sugarcane yield in Bais City, Negros Oriental, a key sugarcane-producing area in the Philippines. Sugarcane productivity in the region has been increasingly influenced by climate variability, particularly changes in rainfall and temperature, which affect crop growth and yield stability. This study analyzes the relationship between climatic variables and sugarcane yield using secondary data on average annual rainfall, temperature, and sugarcane production from 2017 to 2024. A quantitative approach was employed, utilizing descriptive statistics, Pearson correlation analysis, and multiple linear regression to determine the extent to which rainfall and temperature influence sugarcane yield. The regression model was applied to quantify the direction and magnitude of these relationships. The findings reveal a positive association between rainfall and sugarcane yield, indicating that adequate moisture availability supports crop growth and productivity. In contrast, temperature shows an inverse relationship with yield, suggesting that higher temperatures impose physiological stress that reduces sugarcane production. These results demonstrate the sensitivity of sugarcane yield to climatic conditions and highlight the importance of climate-responsive agricultural planning. The study emphasizes the need for adaptive strategies to sustain sugarcane production and protect the livelihoods of communities that depend on the sugarcane industry amid increasing climate variability.
