Tomato cultivation in organic vasoponia using non-composted plant biomass and dairy cattle milk waterfertigation, vegetable residue and automated irrigation
The utilization of waste materials in agriculture as sources of nutrients promotes the increase of productivity and quality of harvested fruits, reducing production costs and environmental pollution. The present work aims to evaluate the productivity and yield of tomato under organic management, using non composted biomass and fertirrigado with milk cattle wastewater. Two experiments will be conducted with the tomato under organic management, at different times: in the periods between June 2018 and October 2018 (winter-spring) and between April 2019 and August 2019 (autumn-spring). The cultivation will be conducted in pots that will be filled with batatais grass pastoral (Paspalum notatum) and low cost automated irrigation. The treatments applied in the first experiment will be irrigation with clean water, fertirrigation with treated wastewater and fertirrigation with raw wastewater. The treatment using wastewater that presents the best productivity and quality of fruits harvested will be used in the second experiment, where the doses of wastewater will be varied. The experimental design used will be entirely randomized. In the tests will be evaluated the growth of the plants (diameter of the stem above the surface of the soil and length of the branches); fruit production per plant in each week, beginning of the harvesting phase at the end of the experiments and classification of fruits harvested for the mean diameters (equatorial and longitudinal) in order to evaluate the effect of fertirrigation with milkwaste. The data obtained will be submitted to analysis of variance and the regression and the means compared using the "t" test of "Student" at 5% of significance. It is expected to obtain the best treatment for fruit production and plant growth using vegetal biomass and wastewater.
