Paper presented at the 52nd CFCS Annual Meeting, Guadeloupe, July 10-16, 2016 The results of this experiment showed that the VAM fungi had a positive influence (p < 0.05) on the production for both varieties of tomatoes. And it also resulted in earlier reproduction. There was no significant difference in production (p > 0.05) between the two concentrations of VAM inoculum used. The treated plants had a higher production, but a lower average fruit weight. More fruits may mean, less nutrients for each fruit, which decreases fruit weight per plant.

Conclusions From this research there can be concluded that: • The VAM fungi had a positive effect on the growth and development • Tomato hybrid 61, inoculated with 2.5 g/plant had the highest biomass production and N and P content • Tomato hybrid 501, inoculated with 10 g/plant had the highest biomass production and N and P content in their tissue • The inoculum had positive influence on the production for both tomato varieties • The inoculum resulted in early reproduction • There was no significant difference in production between the two concentrations of inoculum used. • The recommended dose of 2.5 g VAM inoculum per plant is enough to significantly increase production References Bryla, D.
