Aplikasi Trichokompos Dan Rock Phosphate Pada Tanaman Jagung (Zea Mays L.) Di Medium Ultisol
Corn (Zea mays L.) is a source of carbohydrates after rice in Indonesia. This study aims to determine the effect of trichocompost and rock phosphate fertilizer interaction and the best dose to increase the growth and yield of corn plants in Ultisol. The research was conducted experimentally from May to September 2024 using a completely randomized design (CRD) factorial consisting of two factors, trichocompost (T): 0, 9, 18 g.medium-1 and rock phosphate (P): 0, 9, 18 g.medium-1. The treatments were repeated 3 times, resulting in 27 experimental units. Each experimental unit contained two polybags, so the study consisted of 54 polybags. The data obtained were statistically analyzed using analysis of variance and continued with DNMRT test at the 5% level. The results showed that the interaction of trichocompost and rock phosphate had no significant effect on all parameters of corn plants observed. Dose of 18 g.medium-1 trichocompost increased fresh and dry weight of corn plant biomass, and a dose of 9 g.medium-1 trichocompost increased corn plant height, stem diameter, number of leaves, and corn cob diameter. Dose of 18 g.medium-1 rock phosphate increased fresh and dry weight of corn plant biomass, and a dose of 9 g.medium-1 rock phosphate increased plant height, stem diameter, number of leaves, phosphorus uptake, cobs weight with and without husk, length and diameter of corn cobs.
Keywords: cobs weight, fertilizer interaction, phosphorus uptake, plant biomass
