Increasing Productivity and Biomass of Corn Plants Toward Grant Organic Fertilizer and Liquid Organic Fertilizer

Abstract

The use of corn as animal feed focuses on the use of biomass as feed for ruminants and shelled corn as poultry feed. One of the efforts to increase biomass and protein in corn is by applying fertilizer, namely organic fertilizer. Therefore, the purpose of this study is to determine the effectiveness of using granular and solid organic fertilizers and to determine the best concentration of both types of fertilizers in increasing maize productivity and biomass. The study was designed using a Split Plot Design with an environmental design, namely a Randomized Block Design (RAK). The main plot is organic fertilizer granule petroganik consisting of 3 levels, namely control (G0), 1000 kg ha-1 (G1) and 2000 kg ha-1 (G2). The sub-plots were Biotani liquid organic fertilizer which consisted of 4 levels, namely control (P0), 2 cc/L (P1). 4 cc/L (P2), 6 cc/L (P3). The treatment of granule and liquid organic fertilizer increased the growth potential and productivity of maize. The optimal treatment of granulated organic fertilizer is G1 treatment. Meanwhile, the best treatment for liquid organic fertilizer is P1 treatment. The combination of G1P1 is still recommended even though there is no interaction between granule and liquid organic treatments.
