Characterizaion of bacteria with potential for plant growth promotion in vegetable seedlings

Abstract

Promoting bacteria plant growth, they are a way for the development of bio-fertilizers because they have characteristics as symbiotic nitrogen fixation and phosphate solubilization, decreasing the consumtion of chemical fertilizers therefore can contribute to the sustainable management of production agriculture, improve soil quality and nutrient cycling by microbial action. The agricultural activad with constant use of chemical fertilizers has brought pollution problems, damage to human health, damage and loss of soil microbial biota found there. The use of bacteria with potential plant growth represent an alternative use to replace chemicals and help plant growth. For above the goal of this study it is to characterize the plant growth promoting bacteria isolated in the La Loma Verde Santa Lucia in Cundinamarca, Guasca and determine their influence on the development of lettuce and spinach until seedling stage. For this purpose, the isolated bacteria that exhibit the property of fixing atmospheric nitrogen and solubilization of phosphates will be inoculated in the seeds of lactuca sativa (lettuce) and beta vulgaris (beet) to assess the development of seedlings. Waiting resulting bacteria isolated and characterized promote plant growth of these two vegetables so that the future can encourage the use of these bacteria in techniques in crop production in Cundinamarca, Guasca.
