Assessing the Effects of Different Application Rate of Mykovam on the Growth and Yield Performance of Tomato

Abstract

Tomato (Solanum lycopersicum) is an important vegetable crop in the Philippines because of its nutritional value and wide range of uses. However, tomato production is often affected by poor soil fertility and low nutrient availability, which can reduce plant growth and yield. Biofertilizers such as Mykovam are considered a sustainable alternative to improve nutrient uptake and increase crop productivity. This study aimed to evaluate the effects of different application rates of Mykovam on the growth and yield performance of tomato. The experiment was conducted from January to April 2025 in Purok 3A, Monkayo, Davao de Oro, using a Randomized Complete Block Design (RCBD) with four treatments and three replications, with ten sample plants. The treatments were T1 – Control (no Mykovam), T2 – 5g Mykovam, T3 – 7g Mykovam, and T4 – 10g Mykovam. Differences among treatment means were compared using LSD, with statistical significance determined at p < 0.05. Growth parameters such as plant height, number of leaves, stem diameter, and days to flowering were recorded, while yield parameters included the number of fruits and yield per treatment. Results showed that the application of Mykovam improved several growth and yield parameters of tomato plants. The 7g Mykovam treatment produced better growth performance and the highest mean yield among the treatments. No phytotoxicity was observed in any treatment. Therefore, the application of 7 g Mykovam per plant is recommended to improve tomato growth and yield and support sustainable tomato production.
