Application of Vermichar, Thrichoderma and Biostimulants on Eggplant (Solanum melongena L.)

Aim: This study aimed to determine the effects of integrating inorganic fertilizer with organic amendments on the growth and yield of eggplant.Methodology: A field experiment was carried out at the College of Agriculture, Isabela State University Cauayan Campus, City of Cauayan, Isabela, to evaluate the response of eggplant (Solanum melongena L.) to varying levels of inorganic fertilizer in combination with vermichar and seaweed extract as biostimulants.Generally, the study aimed to determine the effects of integrating inorganic fertilizer with organic amendments on the growth and yield of eggplant.A total of seven treatments, including a control, were laid out in a Randomized Complete Block Design (RCBD).Results: Findings of the study showed that among the treatment's combinations, the application pf 80-20-30 kg NPK ha, 10 bags of Vermichar, and Trichoderma consistently outperformed all the measured parameters such as plant height at 30, 60 and 90 days after planting, number of branches and fruits.Other parameters such as the length, diameter, weight of fruits per plant, per sampling area and computed fruit yield per 1000 square meters were produced by the aforementioned treatment.This treatment also resulted in increased fruit production by 13.93% over the control.Conclusion: Demonstrating the beneficial combination of inorganic fertilizer with organic biostimulants like Trichoderma and Vermichar resulted to better plant growth and fruit development.These findings highlight the synergistic effect of integrating inorganic fertilizer with organic biostimulants such as Vermichar and Trichoderma resulted to an enhanced nutrient availability and increased crop productivity.
