Utilization of vermicompost with the addition of Trichoderma sp. about the growth and production of sweet corn (Zea mays saccharata sturt L.)

Sweet corn (Zea mays L.) is a tropical plant. Sweet corn is more expensive than regular corn. The continuous use of chemical fertilizers has an impact on poor soil quality. Vermicompost with the addition of Trichoderma sp. is an alternative to improve soil quality and prevent sweet corn plant diseases. Research Objectives 1. Test the potency of vermicompost with the addition of Trichoderma sp. 2. Determining the optimum dose of vermicompost with the addition of Trichoderma sp. This research was conducted at the Lampung State Polytechnic. Research locations include analysis laboratories, factory I laboratories and land POF. The time of the study was March 2022 to June 2022. The study used RAK with 3 replications, consisting of a treatment with vermicompost and 1 treatment (without vermicompost and Trichoderma sp). So that with 3 replications and 7 treatments, there were 21 experimental units (trial units). Each experimental unit consisted of 1 plant and all plants became the object of observation. Stem diameter, plant height, cob weight with husk, cob weight without husk, brix had a significant effect between treatments, while number of leaves, leaf length, intensity of downy mildew and leaf rust disease had no significant effect between treatments.
