The effectiveness of liquid organic fertilizer (LOF) Bio M2 on the growth and production of corn (Zea mays L.)

Abstract

The organic fertilizers have more advantages to improve the quality of land. One of the organic fertilizers products is Liquid Organic Fertilizer (LOF) BIO M2. It can be used in food crops. However, the effectiveness test must be carried out for LOF so that it can be developed. The objective of this study is to examine the effectiveness of Liquid Organic Fertilizer (LOF) beside inorganic fertilizer on the growth and production of corn. The research was conducted in Bone, South Sulawesi, on August-December 2017. The experimental design used completely randomized design that consist of nine treatments which were the level of LOF combined dosage of inorganic fertilizer and replicated three times, so there were 27 experiment plots. The results of the study indicate that the use of organic fertilizer can improve land quality by increasing several elements in the soil and the shell of corn was highest in the treatment of LOF 100% and itis recommended fertilizer 75%, for 7,17 tons/ha with RAE 233,33 %.
