BAYARD-VEDEY, Iraida  e  ORBERA-RATON, Teresa de los Milagros. Fertilization of Yardlong bean with bacterial formulations, organic matter and inorganic NPK - Fertilizer. Rev Cub Quim [online]. 2020, vol.32, n.2, pp. 299-310.  Epub 21-Set-2020. ISSN 2224-5421.

The Yardlong bean is a nutritional food rich in proteins, vitamins and nutrients. In Cuba it is grown in organoponics on mixtures of organic matter, which supplied essential nutrients to the crop but are plant hormones deficient. It was evaluated plant growth promoting effects of Brevibacillus borstelensis supplemented and non-supplemented with organic matter, on seeds germination, flower emergence and fruits formation of yardlong bean, in compare to organic matter and NPK-inorganic fertilizer treated plants. The bacteria bioproduct supplemented with organic matter enhanced seeds germination and number of flower in compare to NPK-treated and organic matter-treated plants. However, fruits formation was equal in plants fertilized with Brev. borstelensis supplemented with organic matter and NPK-treated. It was reported for the first time the biostimulant effect of Brev. borstelensis on leguminous species. The bacteria specie shows potential to be applied as biofertilizer on horticulture crops.
