Abstract

Conventional vegetable production is based on the use of chemical fertilizers and pesticides, which contribute to increased food production. However, excessive and inappropriate use of these products can cause several problems to health and the environment. The use of bacteria promoting plant growth, such Bacillus amyloliquefaciens ICBB200 is an alternative, since they act directly on the plant growth due to changes in hormonal levels and increased intake of nutrients such as phosphorus and iron, and also act indirectly by suppressing diseases. Field tests with three different formulations of B. amyloliquefaciens ICBB200 were conducted in lettuce growing areas, in five different soils and climatic conditions in the city of Porto Alegre, Rio Grande do Sul State. After 34 days of cultivation, the plants were collected and evaluated for circumference and fresh weight of aerial part. B. amyloliquefaciens ICBB200 promoted shoot growth of lettuce plants in any of their formulations tested, at all the different conditions tested.
