Abstract

Legume litter can be used as compost with the help of bio-activator Trichoderma sp. as a decomposing microorganism. Legume compost can function as a source of organic fertilizer for plants and can reduce the use of inorganic fertilizers. This study aims to determine the best dose combination using inorganic fertilizer balanced with legume compost fertilizer. The study used non factorial randomized block design with 5 levels of treatment that were control, legume compost 20 ton/ha + 100 inorganic fertilizer, legume compost 30 ton/ha + 75 inorganic fertilizer, legume compost 40 ton/ha + 50 inorganic fertilizer, and legume compost 50 ton/ha + 25 inorganic fertilizer. Based on Anova test showed that the application of various combinations of inorganic fertilizer (Urea, SP-36, KCl) and legume compost had significant effect on the age of 2 WAP, 4 WAP and 5 WAP on the parameters of plant height, significant to the parameters cob weight, and had no significant effect on the sweetness level of sweet corn.
