The Effect of Manure Combination and Liquid Organic Fertilizer (LOF) on Livestock-Integrated Maize Farming Production (Zea Mays L)

This study aims to analyze the reaction in the doses of manure combination and liquid organic fertilizer and their response to the increase in farmer's revenue in a livestock- integrated farming system in Gorontalo. This study was performed in Gorontalo from March to July 2021. The study used a randomized block design with 2 factorials. The first factor is the cow manure dose, and the second factor is the liquid organic fertilizer dose. Data were analyzed using ANOVA and the Tukey Honest Significant Difference (HSD) test. The study results concluded that the most optimal cow manure dose was 10 tons/ha to produce maize at a rate of 5.70 tons/ha, and 20 cc/14 L liquid organic fertilizer was able to generate the most optimal production of 5.67 tons/ha. Integrating 10 tons/ha of cow manure with20 cc/14 L liquid organic fertilizer can generate the most optimal production amounting to 6.83 tons/ha.
