Abstract
This study was conducted to determine the effects of spraying a growth promoting bacterium on chemical contents, yield and growth of tomato (Lycopersicon esculentum L.) and cucumber (Cucumis sativus L.) vegetable species. Different strains of bacteria, Bacillus subtilis BA-142, Bacillus megaeorium- GC subgroup A. MFD-2, Acinetobacter baumannii CD-1 and Pantoea agglomerans FF, were used. The effects of the bacterial treatments on the plant nutrient elements of tomato and cucumber fruit were determined. Its effects on average fruit weight, fruit number per plant, fruit weight per plant, plant length, fruit width and length, total soluble solid and dry matter in tomato and cucumber fruit were also determined. The effects of bacterial application on plant mineral contents were significant. Bacterial applications increased mineral contents of tomato and cucumber fruit as compared to control treatment. All bacterial applications particularly affected on improving the in N, P, Mg, Ca, Na, K, Cu, Mn, Fe and Zn contents of the fruit. Growth promoting effects of bacterial application on the plant growth parameters except TSS (Total soluble solid) were significant. The highest average fruit weight, fruit weight per plant and plant length were obtained from Pantoea agglomerans FF applications in tomato as comparing to that of the other applications. Fruit number per plant was high in Acinetobacter baumannii CD-1 application and fruit width, fruit length and dry matter were highest in Bacillus megaterium-GC subgroup A., MFD-2 application than that of the other application in tomato. The highest fruit number per plant, fruit weight per plant, plant length, fruit width, fruit length and dry matter were obtained from Pantoea agglomerans FF applications in cucumber as compared to that of the other applications and the highest average fruit weight was found in Bacillus megatorium-GC subgroup A. MFD-2 application when compared to the other applications. The results of this study showed that Pantoea agglomerans FF, Acinetobacter baumannii CD-1 and Bacillus megaterium-GC subgroup A. MFD-2 have a great potential to increase the yield, growth and mineral contents of tomato and cucumber vegetable species.
