COMBINATION OF PLANTING METHODS AND MULTIPLE NPK FERTILIZER ON PLANT GROWTH AND PRODUCTION SWEET CORN (Zea mays saccharata Sturt)

This study aims to obtain differences in the response of growth and yield of Sweet Corn (Zea mays saccarhata Sturt) using a single row planting system and a two row planting system. This research was conducted in Sukajadi Village, Banyuasin Regency, South Sumatra Province. Research time in January. This study used a split plot design with 8 treatment combinations which were repeated 4 times. The treatment factors in question are as follows: Main Plot : Single Row Planting System (S1), Two Row Planting System (S2), P0: No treatment , P1: NPK : 60g (plot) P2: NPK : 120g (plot) P3 : NPK : 180g (plot). The variables observed in this study were plant height/plant (cm), length of seed cob/plant (cm), cob weight/plant (gr), production of plots/plot (kg). Based on the results of the study, it was shown that the treatment with a two-row planting system (DB) and application of 300kg/ha compound NPK fertilizer gave the best effect on sweet corn production of 12.96 kg/plot or equivalent to 17.28 tons/ha.
