This study evaluated the effect of Lactobacillus fertilizer on product yield of Vigna radiata (mung bean). The study utilized ninety (90) drainage pots that were filled with sterilized soil. Each pot was planted with one (1) seed of mung bean and was allowed to grow and germinate. Once germinated, the plants were randomly assigned into five (5) groups. Eighteen (18) plants were assigned to one (1) negative control group with no fertilizer, thirty-six (36) plants assigned to two (2) positive control groups, with eighteen (18) plants having one (1) tablespoon and another eighteen (18) plants having one-half (1/2) tablespoon complete 14-14-14 fertilizer, and another thirty-six (36) plants were assigned to two (2) experimental groups, with eighteen (18) plants having 100% concentration and another eighteen (18) plants having 50% concentration of Lactobacillus fertilizer. The Lactobacillus fertilizer was produced following the Lactobacillus Serum method made by Gil Carandang in 2013. The complete 14-14-14 fertilizer was used as an industrial standard. The study was conducted within the garden area of our research member in Vista Grande Subdivision, Talisay City, Cebu and the plants were monitored weekly. Once the plants produced their seeds, they were immediately collected and weighed using a weighing scale. The data was then tabulated using a data sheet.
Results showed that the fertilizers affected the yield of the Vigna radiata plants. The mean weight (g) from the no fertilizer group had a value of 3.87±0.39; while the 100% and 50% Lactobacillus fertilizer groups had means of 4.66±0.89 and 3.91±0.90, respectively; and the 1 tablespoon and ½ tablespoon complete 14-14-14 fertilizer groups had means of 4.48±0.97 and 4.48±0.97, respectively. Brown-Forsythe test showed a significant difference among the experimental and the control groups at 0.5 level of significance, F (4, 70.762) = 3.116, p < 0.05. Tukey's Post-Hoc Test showed that the 100% Lactobacillus fertilizer and the 1 tablespoon complete 14-14-14 fertilizer had the same seed weight (g) among the plants' respective group.
The study concluded that Lactobacillus fertilizer has an effect on the product yield of Vigna radiata. The researchers recommend farmers, the Department of Agriculture, and Biology teachers to be aware of the advantages of Lactobacillus fertilizer and utilize it in their professions. In the interest of future studies, the researchers would like to recommend to provide extra number of plants just in case of plant decay as experienced, provide a wider area to set-up the different groups for easy and comfortable application of treatments, and put into consideration the shade intolerance of the Vigna radiata plants as observed.
