ROBLERO RAMIREZ, Hugo Rubili et al. Evaluation of five vermicompost doses in tomato (Solanum lycopersicum) cultivation in Sinaloa, Mexico. Rev. Mex. Cienc. Agríc [online]. 2014, vol.5, n.spe8, pp.1495-1500. ISSN 2007-0934.

The excessive use of agrochemicals decrease productivity of agricultural soils, while organic fertilizers improve their physicochemical properties. Vermicompost is a viable alternative for improving the structure and amount of nutrients in the soil, therefore the aim of this study was to evaluate different vermicompost doses in tomato crops (Solanum lycopersicum L.) in northern Sinaloa. Vermicompost doses of 0, 500, 1 000, 1 600, 2 000 and 4 000 kg ha-1 were tested including a control, in a completely randomized design with three replicates per treatment. The estimated variables were fruit size, number and weight. The addition of more than 4 000 kg ha-1 of vermicompost significantly increased the fruit number and size in tomato plants hence it is considered a viable option for use in commercial tomato crops.
