The reliance of mangifera indica linn yield production based on insolation pattern in Perlis , Malaysia / Muhammad Sariman Baharuddin

This study examines the relationship between solar radiation (insolation) and Harumanis mango yield in Perlis, Malaysia, using GIS and spatial analysis techniques. The results show no significant correlation between insolation levels and mango yield. The linear model has an R² value of 0, indicating no relationship, while the exponential model has an R² value of -0.04, suggesting a very weak relationship where only 4% of yield variability is due to insolation levels. This highlights the complexity of the relationship between solar radiation and crop yield, which is influenced by many factors. While higher solar radiation can generally increase photosynthesis and yield, this relationship is not always straightforward. The study emphasizes the need for a comprehensive approach to understanding agricultural outcomes. Future recommendations include expanding datasets to consider more variables, conducting longitudinal studies to capture seasonal variations, and improving agricultural practices like integrated pest management and irrigation. These steps are essential for sustainable mango production in Perlis, enhancing resilience and productivity in tropical mango cultivation, and supporting agricultural sustainability in Malaysia.
