Abstract

The objective of this study was to study the influence of mixed planting materials and chemical fertilizers on the amount of leaf phosphorus content that affects the number of inflorescences and fruit set in mangoes. The results showed that, before the experiment, the chemical fertilizer (15-15-15) had the highest phosphorus content. Among the mixed planting materials, PM3 contained the highest phosphorus content. Soil analysis revealed that phosphorus levels were highest in the T4(PM3), T3(PM2), T2(PM1), T1(15-15-15), and T0(Control) treatments, respectively, with significantly difference (p<0.05). An analysis of phosphorus in mango leaves revealed that T4 (PM3) had the highest content at 0.18%. Moreover, T4 (PM3) produced the highest number of inflorescences per plant (421) and the highest fruit yield per plant (532.25 fruits). Therefore, it can be concluded that the mixed planting materials result in higher phosphorus content in mango leaves and a greater number of inflorescences and fruit set compared to chemical fertilizers, with the difference being statistically significant at the 0.05 level.
