Abstract

Poblano chili (Capsicum annuum L.) is a widely consumed variety in our country, but there are several problems that affect its cultivation and production. Considering the above, the objective of this research was to elaborate and compare the effect of two biofertilizers with rhizobacteria on the growth of Poblano chili seedlings. The research was conducted at the Postgraduate College, Montecillo Campus in the years 2015-2016. The work was carried out in three stages: 1) selection of culture media and growth dynamics of four strains of rhizobacteria; 2) elaboration of two bioformulations using alginate and peat pearls as carriers; also, the viability of the rhizobacteria was evaluated for five months; and 3) evaluation of the effect of bioformulations in promoting the growth of Poblano chili seedlings. Serratia strains showed the highest growth in the TBS culture medium, while Pseudomonas strains had high growth in Luria-Bertani broth. The stationary phase of the Pseudomonas strains was reached between 24-48 h and that of the Serratia strains between 12-44 h. The shelf life of the two formulations was maintained from 1 x 1012 to 1 x 109 CFU for five months. The application of alginate beads in the seedlings stimulated seedling growth up to 35% with respect to the control. The application of biofertilizers based on alginate and peat pearls is a good option to promote the growth of chili seedlings.
