ABSTRACT
The research of using fertilizers of solid oil palm leftovers with cow cattle waste to growing and producing of sweet corn had completely done. The research was carried out in Sei Mencirim Village, Sunggal Sub-district, Deli Serdang, North Sumatra, April - September 2019. The purpose of the study was to see the impact of combination of solid oil palm waste (SOPW) with Solid Cow Cattle Waste (SCCW) to growth and productions of sweet corns. Randomized Factorial Group Design was used with 12 treatments and 3 replications, factor I: combinations of SOPW and SCCW, symbol “C” in three measures: C1 (100% SOPW), C2 (50% SOPW + 50% SCCW) and C3 (100% SCCW); Factor II: the doses of the fertilizers, symbol “D” in 4 stages: D0 (control), D1 (5 ton/ha), C2 (10 ton/ha), D3 (15 ton/ha). The data obtained were analyzed by Duncan's Multiple Range Test (DMRT), The size of each plot was 2 m x 1.5 m. Result of the study shown, there is a significant difference (p < 0.05) of plants height (cm), stems’ diameter (mm), leafs’ wide (cm2), cobs diameter (cm), production per sample (g) and total production (ton/ha) by the effects of using combination of solid oil palm waste (SOPW) with solid cow cattle waste (SCCW) to growth and productions of sweet corns.The combination of 50% SOPW and 50% SCCW (C2) was the best and the field trial had shown that the amount of 10 tons/ ha (D2) of the fertilizers produced 6.77 tons of sweet corn.
