Biofertilizer from plant probiotic microorganisms

Abstract

Nowadays, farmers are increasingly interested in biofertilizers using to grow crops because it does not cause soil deterioration and environmental friendly. Therefore, the aim of this research was to study on the efficacy of biofertilizer fermented with two plant probiotic microorganisms Lactobacillus casei and Bacillus subtilis on growth of Chinese morning glory (Ipomoea aqatic Forsk). Five formulas of biofertilizers including (1) L. casei fermentation, (2) B. subtilis fermentation, (3) combination of L. casei and B. subtilis (1:1) fermentation, (4) combination of L. casei and B. subtilis (3:1) fermentation and (5) combination of L. casei andB. subtilis (1:3) fermentation were produced and used to Chinese morning glory cv.‘Yodpai-9’ and ‘Kaewmorakot’ growing for 35 days. The result showed that the highest growth rate of two cultivars was observed in 1:3 fermentation of L. casei and B. subtilis. The maximum average of fresh weights, dry weights and stem heights were significantly difference (p<0.01), except root lengths. This result indicated that mixed cultures of L. casei and B. subtilisfermentation was appropriated for Chinese morning glory growing. This information useful for biofertilizer developmental process for other plant species.
