The Effectiveness of Liquid Bio-Fertilizer on Rice Plants (Oryza sativa) and the Analysis of Farming Business
Efektivitas Pupuk Hayati Cair pada Tanaman Padi Sawah (Oryza Sativa) Serta Analisis Usaha Taninya
Farmers in Indonesia are beginning to understand the importance of biofertilizers with standardized quality and effectiveness required by the Indonesian Ministry of Agriculture. So that many biological fertilizers circulating in the market need to be researched to test their quality and effectiveness. The purpose of this study was to test the quality and effectiveness, as well as farm business analysis of liquid biological fertilizers on lowland rice (Oriza sativa). The treatments were arranged in 5 levels of fertilization, namely: without application of fertilizer or control (P0), 1.00 dose of NPK (P1), 1.00 dose of NPK + 1.00 dose of biological fertilizer (P2), 0.75 dose of NPK + 1.00 dose of biological fertilizer (P3), 0.50 dose NPK + 1.00 dose of biofertilizer (P4). The experiment was carried out with 4 replications so that there were 20 experimental units. Each experimental unit is a plot of land with an area of 25 m2. The results showed that the quality test met the criteria of Ministry of Agriculture No. 1 of 2019, also the application of biological fertilizers in the field in general resulted in the growth and yield of lowland rice plants that were the same as the comparison, and better than the control treatment. The treatment of 0.75 doses of NPK + 1.00 doses of biological fertilizers is the most effective and beneficial treatment agronomically with an RAE value of 100%, and economically with an R/C value of 1,83.
