Comportamiento de ocho cepas de hongos Micorrizicos (MVA) en semilleros de tomates (Lycopersicum esculentum Mill) en suelos pardos sin carbonatos de Holguín.

In november of the years 1994 and 1995 was perfomed this research behaviour studing of eight fungus strains (VAM) in tomato seedbed in brown carbonaless soil of the Agricultural research territorial centre in Holguin.

Glomus mosseae strain was more effective continuos by Glomus fasciculatum, manihoti and agregatum satrains, that also exceed the treatment with NPK. This satrains weth apropiate handling maybe stay reduced of the plants between 5 and 7 day in the seedbed as obtain most vigorous plants, low cost and high ecological value.
