Agronomical response of tomato crop to application of native actinomycetes strains (Original)
Keywords:
tomato; actinomycetes; yield; inoculationAbstract
The present research was carried out under Intensive Orchard conditions “El Gigante” belongs to Manzanillo municipality, Granma province since October/2015 to January/2016 on Cambisol soil in order to evaluate the agronomical response of tomato crop (Solanum lycopersicum L. cv. Vyta) to application of three native actinomycetes strains (A23M12, A18M7 y A5M4). The plant growth variables: plant height, fruits number for plant, fruit fresh mass and crop yield were evaluated. An economical analysis also was performed. The A23M12 strain showed the best results both for all studied plant growth variables as crop yield with 43,8 t ha-1. The inoculation of this bioproduct had a very high economical impact on this crop since decreased the production costs and significantly increased the profit and rentability index in comparison with control plants (not inoculated plants).
