GROWTH RESPONSE AND YIELD OF SWEET CORN (Zea mays saccharata Sturt) AGAINST MIRACLE GRO AND MANURE FERTILIZER APPLICATION

The research was conducted in the Tanjung Sari village, Sei Dadap, Asahan, North Sumatraprovince with a height of ± 17 m above sea level, tipy of climate C (oldeman). This study wasconducted in Mey to July 2017. The study design was a Randomized Block Design (RBD)Factorial consisting of 12 treatment combinations, each 4 levels application of Miracle Grofertilizer is: M0 = 0 g Miracle Gro/l water (control), M1 = 1 g Miracle Gro/l water, M2 = 2 g Miracle Gro/l water, M3 = 3 g Miracle Gro/l water and 3 levels of manure fertilizer is: K0 = 0 tons/ha (control), K1 = 15 tons/ha (4,5 kg/plot), K2 = 30 tons/ha (9 kg/plot). The results showed that giving Miracle Gro of concentration 3 g/l water (M3) on sweet corn can increase the growth of crop height age of 2, 4 and 6 Weeks After Planting (WAP); stem diameter ages 6 WAP; the number of leaf age 2, 4 and 6 WAP; weight of cob weighs per plot; weight of cob without any weight per plot. Giving manure fertilizer up to dose 30 tons/ha (K2) on sweet corn can increase the growth of crop height age of 2, 4 and 6 WAP; stem diameter ages 6 WAP; the number of leaf age 2, 4 and 6 WAP; weight of cob weighs per plot; weight of cob without any weight per plot. Interaction of giving Miracle Gro and manure fertilizer very significant effect on plant height, weight of cob weighs per plot; weight of cob without any weight per plot. The interaction is best obtained in treatment M3K2 (3 g Miracle Gro/l water and 30 tons/ha of manure fertilizer).
