Abstract

Corn is a leading commodity sector of food crops that are useful and have high economic value to be cultivated or developed. There needs to be an effort to increase corn production, one of which is by fertilizing. The use of biological agents to provide biofertilizers that are more useful for plants is the most feasible alternative in an effort to increase the availability of nutrients in the soil. One biological agent that has the potential to help plant growth is the fungus Trichoderma sp. The purpose of this study was to see the growth response of corn plants to the application of Biofertilizer Trichoderma sp. with various dosages. The research was conducted from November 2023 to January 2024 at the Rawasari experimental garden, Kel. Munjuljaya, Purwakarta Regency. The study used a Group Randomized Design (RAK) with 5 dose treatments of Trichoderma sp., namely: 0 gr; 15 gr; 30 gr; 45 gr; and 60 gr. There are 5 treatment combinations with 5 repetitions. Observation variables are growth components (plant height, number of leaves, stem diameter and flowering age). The results showed that the best response growth component was 60 gr treatment dose of Trichoderma sp. against plant height (78.13 cm), number of leaves (11.52). stem diameter (2.8 cm) and flowering age (48.02 days).

Abstract

Cauliflower (Brassica oleracea var. botrytis L.) is one of the vegetables widely consumed by Indonesian people. Cauliflower productivity in Indonesia has decreased in recent years. Plant growth and production can be influenced by internal factors of the plant itself and external factors such as climate, soil, sunlight intensity, nutrients, and OPT. Fulfillment of plant nutritional needs is done by providing fertilizers, both organic fertilizers (biological and non-biological) and inorganic fertilizers. This study aims to test the use of organic solid biofertilizers on the growth and weight of cauliflower harvests. The research method used was a randomized block design (RAK) consisting of 6 treatments and 4 replications to obtain 24 experimental units. The treatments used were treatment A (100% solid biofertilizer), treatment B (solid biofertilizer + 75% dose of inorganic fertilizer), treatment C (solid biofertilizer + 50% dose of inorganic fertilizer), treatment D (solid biofertilizer + 25% dose of inorganic fertilizer), treatment E (100% dose of inorganic fertilizer), and treatment F (without fertilization/control). The results showed a significant effect on the provision of solid biofertilizer and inorganic fertilizer on plant height, number of leaves, and wet weight of the harvest, while the stem diameter had no significant effect. Meanwhile, there was no significant difference between the treatments of using solid biofertilizer and inorganic fertilizer.
