Influence of different nitrogenous levels and Glomus fasciculatum on the morphologic variables of the tomato

The tomato cultivation is the great economical importance on the world. In the present work the use of the mycorrhizal fungi and the nitrogenated fertilization in the growth, nutrition and yield of tomato (Solanum lycopersicum, Lin.) variety Vyta were carried out. The experiment in field with a randomly blocks design with 8 treatments and 4 replicate at Cautillo's locality in Jiguani municipality belonging Granma province were executed. In this experiment was combined Glomus fasciculatum with the 60 % and 75 % of nitrogen indicated for this cultivation aside from the use phosphorus and potassium a fixed bottom. The results evidenced the effectiveness of G. fasciculatum over yields. The system optimization with the reduction of 40 % of the nitrogen and a yield increase over of the doses taken as reference.
