A study on the Efficacy of Mycorrhiza on the Growth and Yield of Hot Chili Pepper was conducted from March to July 2022. This study was conducted mainly to determine the effects of Mycorrhiza on the growth and yield response of hot pepper particularly on its the plant height, days to flower, root shoot ratio, weight of fruit, number of fruit per plant, number of marketable and non-marketable fruits, extent of mycorrhiza, and the computed yield per hectare. A field experiment was established at Purok 3 Turu, Magalang, Pampanga where Complete Randomized Design was used as the experiment design. The following are the treatments: TlFarmers Practice; T2 - Mycorrhiza; T350% less imorganic + mycorrhiza; and T4 - RR of Inorganic + RR of mycorrhiza. Data gathered were analyzed using the Analysis of Variance (ANOVA). Least Significant Difference (LSD) was used to determine the significant different of each treatments. Based on the results, it can be noted that the application of mycorriuaa has affected the days to flower and number of non-marketable fruit. However, ao significant difference was observed as regards plant height, weight of fruit per plant. gumber of marketable fruit and computed yield per hectare. Among the treatments, T2 - Mycosriuza gained the highest net income.
