Effects of two biofertilizers on tomato (Solanumly copersicum L) crop yield

Abstract

The research was conducted between January and March 2024 on the farm belonging to producer Yunieski López Rodríguez, from the Guillermo Castro CCS (Central Agricultural Research Council). The objective was to evaluate the response of tomato crops to two biofertilizer variants. The experiment was set up on a loose carbonated sialitic brown soil. The biofertilizers used were commercial strains of Azotobacter chroococcum with a titer of 10x1010 cfu mL-1, and Fosforina (Pseudomonas sp. strain IS-16) with a titer of 7x10⁸ufcmL-1, supplied by the Soil Institute. The biofertilizers were applied by direct spraying to the soil and the leaves of the tomato seedlings used. The results indicate that the use of the Azotobacter chroococcum strain and Fosforina offers several agronomic advantages, enabling improved yields in agricultural practices.
