Evaluation of Mixtures of Beneficial Microorganisms on Brassica chinensis L.
Brassicaceae (the mustard family, previously Cruciferae or the crucifers) include many foods, forage, ornamental, and weed plants. Organic production of brassica crops, or any commodity, relies on management techniques that replenish and maintain long-term soil fertility by optimizing the soil’s biological activity. This is achieved through crop rotation, cover cropping, and composting and by using organically accepted fertilizer products that feed the soil while providing plants with nutrients. Excessive use of chemical fertilizers, pesticides, and herbicides in uncontrolled amounts and methods will damage the land farm, pollute the environment, and contaminate the food due to their residues. The use of aromatic-degrading bacteria Alcaligenes sp., Pseudomonas sp. in combination with Azospirillum sp., Azotobacter sp., Bacillus subtilis, Actinomycetes, and Lactobacillus sp. will remediate the soil farm. In this study, we have evaluated the mixtures of these beneficial microorganisms on Brassica chinensis L. due to their previous efficacies on various cropping systems. The experiment was a randomized complete block design with nine treatments and three replications per treatment. Our results showed that the mixtures of those microorganisms showed beneficial effects and could be implemented as biofertilizers for the production of Brassica spp. in the farmlands in Indonesia.
