PRODUCTION OF CHERRY TOMATOES FERTIGATED UNDER DIFFERENT TYPES OF ORGANIC SUBSTRATES IN THE MUNICIPALITY OF BREVES, MARAJÓ ISLAND – PA

Abstract

There are many factors that directly affect tomato production, even making the crop unfeasible in some regions of Brazil. Thus, the research aimed to evaluate the fertigated production of cherry tomatoes under different types of organic substrates. The research was carried out in a greenhouse with microclimatic monitoring with the crop (cv. sweet grape) being produced in 8l pots conducted on a single stem, under cultivation different levels and types of organic substrates, being fertigated automatically via sphaguet. The results showed that the vegetative growth of the plants suffered little interference from the treatments and microclimatic conditions, but the production was drastically impaired by the microclimatic inclement weather. Thus, it is concluded that the cultivation of cherry tomatoes can be carried out in the Marajó region with decomposing wood sawdust (mill) replacing the traditional coconut fiber.
