Vermitea is a water extract from vermicast, which is rich in nutrients such as N, P, <, Ca, and growth promoting rhizobacteria. To help meet the demand for peanut woduction while reducing the use of synthetic fertilizer, a study on the growth and yield erformance of peanut as influenced by level and frequency of vermitea application was onducted in San Jose Malino, Mexico, Pampanga mainly to evaluate the growth, yield yerformance and profitability of peanut.     Levels of vermitea namely: Aj (without vermitea, control): Az (10% concentration of vermitea); A3 ( 20% concentration of vermitea); Ay (30% concentration of vermitea); As (recommended rate of fertilizer, check treatment) were imposed using frequency of pplication (once a week and every two weeks interval). A total area of 462 m? was used n the experiment following the procedure in Two-Factor Factorial in Randomized     complete Block design (RCBD) with three replications. Levels of vermitea were the nain treatments and frequency of application served as the sub-treatments.     The results showed that foliar fertilization of 10%, 20%, and 30% vermitea had a significant effect on plant height at flowering, total dry matter, weight of 100 seeds, umber of pods per plant, weight of pods per plant, pod yield per hectare, seed yield per iectare, marginal benefit cost ratio, and cost and return analysis. With varied levels 10%-30%) of vermitea, treatments with the recommended fertilizer rate provided similar esults, Plant height at harvest, shelling percentage and number of seeds per pod however, showed no significant variations.     Furthermore, the findings revealed that there was no substantial effect on the requency and interaction effect between levels and frequency of vermitea on the agronomic characteristics and yield performance of peanut.     The cost and return analysis indicates that peanut treated with vermitea had a net 'evenue of Php 98, 000-120,000/ha, with a ROI of 133-163% regardless of the levels and requency of application. In addition, an additional benefit of Php 2.49-10.57 is obtained ising vertmitea application.
