Abstract

The demand for sweet corn from year to year has increased dramatically, especially in big cities. One of the limiting factors for sweet corn plant growth is the population size of a plant and soil nutrient status. Based on this, it is necessary to increase sweet corn yields, including by adjusting the appropriate spacing and giving granulated organic fertilizer with the right dose as a source of nutrients. The study was conducted in Mandai District, Maros Regency, South Sulawesi Province, from April to August 2019. This study is a factorial experiment using a Randomized Block Design consisting of two factors. The first factor is the spacing of the plants consisting of J1 = 70 x 20 cm spacing- J2 = spacing of 70 x 30 cm- and J3 = 70 x 40 cm spacing. While the second factor is the dose of granules of organic fertilizer which consists of three levels, namely: G1 = granular organic fertilizer 1 t ha-1- G2 = granules organic fertilizer 2 t ha-1, and G3 = granules organic fertilizer 3 t ha-1. The results showed that the interaction between the spacing treatment and the application of granulated organic fertilizer had no significant effect on plant height and number of leaves, but had a significant effect on the parameters of leaf area, length of ear, the weight of cob without cob, diameter of the ear, weight of 100 grains, number of rows per cobs, number of seeds per row, and yield of sweet corn. In general, sweet corn^s best growth and yield were obtained at a spacing of 70 x 20 cm with the application of organic fertilizer granule 2 t ha-1, which is 11.3 t ha-1.
