Abstract

This research was carried out in Maret - Juli 2019 in the Garden of the Faculty of Agriculture, Jalan PBSI Percut Sei Tuan sub district, Deli Serdang Regency, North Sumatra Province, Alluvial soil type and altitude of 25 m above sea level. The method used in this study is a Factorial Randomized Block Design (RBD), which consists of 2 treatment factors, namely: 1) Giving compost (Knotation), consisting of 4 levels of treatment, namely: K0 = control (cow manure) ); K1 = compost the skin of the coffee at a dose of 1 kg / m2; 2 = compost the skin of the durian at a dose of 1 kg / m2; K3 = Kepok banana peel compost at a dose of 1 kg / m2, and 2) giving of liquid organic fertilizer of cabbage waste (P notation), consisting of 4 treatment levels, namely: P0 = control (without Liquid Organic Fertilizer cabbage waste); P1 = giving of Liquid Organic Fertilizer at adose of 10 ml / liter of water; P2 = giving of Liquid Organic Fertilizer at a dose of20 ml / liter of water; P3 = giving of Liquid Organic Fertilizer at a dose of 30 ml /liter of water, each treatment is repeated 2 (two) times. The parameters observedin this study were plant height, number of leaves, number of tubers per sampleplant, production per sample, production per plot and percentage of plant disease attack.As for the results obtained from this study, namely: 1) Giving various types of fruit skin compost did not significantly affect height, number of leaves, number of tubers, production per sample plant and production per plot of onion plants; 2) liquid organic fertilizer cabbage application has no significant effect on height, number of leaves, number of tubers and production per sample plant, but has a significant effect on production per plot of onion plant; and 3) Combination between the fruits compost and the liquid organic fertilizer that is not real influence on the plant height, the number of leaves, the number of bulbs and production per crop samples, but the effect is very real towards production perplot of the anion plants
