Pemanfaatan Daun Tanaman Berkayu Sebagai Pupuk Organik Tanaman Sayuran dan Jagung

This study aimed to use woody plant leaves as organic fertilizer (compost) and their effects on vegetables and corn. The compost was made from leaves of Samanea saman, Swietenia macrophylla, Nephelium lappaceum and cow dung (1:3, 2:2 and 3:1) using OrgaDec (0.5% w/w), Decomic (0.1% v/w) and Dectro (0.1 v/w) as bioactivator. The result showed that compost from Samanea saman leaves and cow dung (1:3) using Decomic (0.1% v/w) met the organic fertilizer standard. The compost was applied to Ipomoea reptans, Capsicum annuum and Zea mays on a media from compost and latosol soil (1:3, 2:2 and 3:1) using Completely Randomized Design (CRD) with 3 replications. The analyzed data using ANOVA showed no significant difference in the growth parameter of tested plants. The best media for Ipomoea reptans was the mixture of compost and latosol soil (3:1) meanwhile for Zea mays and Capsicum annuum were 1:3 and 2:2, respectively. (Ludya/Pustakawan)
