Influence of Planting Spacing and Compost Application Rate on Corn (Zea mays L) Growth and Production

This study investigated the effects of planting distance and compost fertilizer application rates on corn growth and yield. A Randomized Complete Block Design with three levels of planting distance (70 x 10 cm, 70 x 20 cm, and 70 x 30 cm) and three levels of compost fertilizer (0, 5, and 10 tons/ha) was employed. Results showed that planting distance of 70 x 20 cm maximized leaf number, seed weight per plot, and seed yield per hectare. The application of 10 tons/ha of cow manure compost significantly increased plant height, ear diameter, and seed weight per ear. However, no significant interaction was observed between planting distance and compost fertilizer application rates on corn growth and yield.
