ALONSO LOPEZ, Alejandro et al. Evaluation of vermicompost and tezontle in tomato (Lycopersicon esculentum Mill.) In greenhouse. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.5, pp.967-975. ISSN 2007-0934.

In Mexico, the tomato (Lycopersicon esculentum Mill.) Is one of the most important vegetables for the value of their production and acreage. One factorthat in recent years limited their production are: prolonged droughts, eroded soils, pests and diseases. In order to evaluate the changes produced by vermicomposting and tezontle in the development and growth of tomato was carried out this work in greenhouses. The treatments were: Treatment 1 tezontle+vermicompost+coal (47.5%+47.5%+5%), Treatment 2 tezontle+vermicompost + coal (57.5% + 37.5% + 5%), Treatment 3 tezontle + vermicompost + coal (67.5% + 27.5% + 5%), Treatment 4 tezontle (100%) and five treatment vermicompost soil+(95% + 5%). Treatment 5 was the control treatment. Two beds of 10 x 1 m per treatment, making a total of 10 terraces, with 10 repetitions. The work was conducted in the city of Xalapa, Veracruz. Was analyzed under a completely randomized design. Height, number ofleaves, number ofinflorescences, number of total fruits, number ofharvested fruits, average fruit weight and yield: the variables were measured.An analysis ofvariance and mean comparison tests with Tukey (∝= 0.05) was performed. It was concluded that there are no significant differences among the five treatments. However, according to trends and performance based, land use as substrate is recommended.
