Producing local microorganisms (MOL) based plant booster and determining its efficiency on green mustard (Brassica rapa var. parachinensis L)

Local Microorganisms (MOL) is a fermented solution product that made from various organic resources. MOL acts as a living medium and the development of microorganisms useful for accelerating the destruction of organic matter. The objectives of this study are to produce MOL-based plant booster from fruits and determine its efficiency towards green mustard (Brassica rapa var. parachinensis L). This study was done by using three different local fruits. This study used a research design with six different formulations. It was tested on six treatments with four repetitions and six different formulations represented the concentration of MOL consists of 1%, 5%, 10%, 20%, positive and negative control. The parameters that were analyzed were the height of plants, number and size of leaves using different treatments and were measured weekly for six weeks. The data were analysed using analysis of variance (ANOVA) followed by a Duncan post hoc test to determine whether there are significant differences in the selected growth parameters of green mustard (Brassica rapa var. parachinensis L) due to treatments. This study showed parameters of the mean height of plants ranged from 21.45 to 25.73 for six weeks of observation. Meanwhile, the mean number of leaves ranged from 9.50 to 11.75 and the mean size of leaves ranged from 0.58 to 0.96 for six weeks. The parameter showed significant different from week 3 to week 6 and 20% of MOL solution are recommended to use. To conclude, MOL is suitable as an organic fertilizer because it effectively applied on the plants as a growth-promoting or growth booster for vegetables.
