Abstract
The Bioboost is a biological fertilizer containing superior soil microorganisms, useful for increasing soil fertility as a result of soil biochemical processes, including increasing nitrogen in the soil which can increase the growth and yield of melon plants. This research was conducted in Jamaimo Village, Mariat District, Sorong Regency, and analyzed soil samples at the Laboratory of Soil Fertility and Chemistry, Department of Soil Science, Hasanuddin University from July to November 2020. This study used a single factor with a randomized block design consisting of 4 levels of treatment. Each treatment was repeated 4 times to obtain 16 experimental units. The Bioboost concentration treatment is as follows: P1 = with a concentration of 500 ml of bioboost + 1000 ml of water- P2 = with a concentration of 700 ml of bioboost + 800 ml of water- P3 = with a concentration of 900 ml of bioboost + 600 ml of water- P4 = with a concentration of 1100 ml of bioboost + 400 ml of water. The results showed that the higher the concentration of bio boost fertilizer, the higher the nitrogen and C-organic elements contained in the topsoil Alfisol and the optimal growth and yield of melons.
