Abstract

This research was carried out on the experimental field of the University of Medan Area Jl. PBSI Medan Estate Percut Sei Tuan Subdistrict Deli Serdang Regency, with altitude of 12 m above sea level, flat topography and alluvial soil type. This research was conducted from September to January 2019. This research was conducted using Factorial Randomized Block Design (RBD) method consisting of 2 treatment factors, namely: 1) Chicken manure (P notation) which consists of 4 levels of treatment, namely: P0 = No treatment; P1 = Compost 10 tons ha (1 kg / plot); P2 = Compost 15 tons ha (1.5 kg / plot); P3 = Compost 20 tons ha (2 kg / plot), and 2) Organic fertilizer palm oil liquid waste (K notation) which consists of 4 levels of treatment, namely: K0 = No treatment; K1 = Liquid waste 10 ml / L; K2 = Liquid waste 20 ml / L; K3 = Liquid waste 30 ml / L, each treatment was repeated 2 times. The parameters observed in this study consisted of plant height, number of leaves, stem diameter, production gross weight per sample, production gross weight per plot, net production weight per sample and net production weight per plot. The results obtained from this study, namely: 1) Provision of chicken manure compost has a significant effect on plant height, stem diameter, production gross weight per sample, production gross weight per plot, net production weight per sample and net production weight per plot, but influential not real to the number of leaves. Provision of 1 kg / m2 chicken compost can significantly increase plant growth and production; 2) The provision of palm oil liquid waste has no significant effect on the growth and production of maize plants and 3) The combination of factors of chicken manure compost and palm oil liquid waste has no significant effect on the growth and production of corn plants.
