Description : Tomato is one of the most popular vegetables in the world. Therefore, for improvement in crop productivity in Suriname and most other countries, excessive application of pesticides and synthetic fertilizers is used. These result in gradual depletion of soil fertility and microbial diversity. Conventionally managed soils are found to exhibit a poorer micro flora and a lower biological activity then organically managed soils. Recently much attention is paid to organic cultivation and the use of bio fertilizers as a supplement for chemical fertilizers. VAM fungi have the potential to improve the sustainability of tomato production by improving yield and quality. Therefore, the aim of the study was to evaluate the effect of two different concentrations of commercially available vesicular - arbuscular mycorrhiza on the plant growth and fruit production of two tomato varieties (Lycopersicon esculentum Mill.) in the greenhouse.The experiment was set up as a randomized factorial block design with two independent factors and consisted of six treatments and three replications. The factors were two tomato varieties: hybrid 61 and hybrid 501 and two concentrations of VAM namely 2.5 and 10 g. VAM/plant. Biomass was determined two times, at bloom initiation and at the end of the experiment. The growth parameters were measured once per week. The production was recorded only for the first two harvest times. Data was statistically analyzed using three-way ANOVA. 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.
