Produção e qualidade do tomate de mesa submetido à adubação verde intercalar

Abstract

The intercropping of tomato with legumes has called the attention of producers, because it is a renewable source of nitrogen and can promote improvements in the physical chemistry and microbiological characteristics of the soil. However, few studies have been conducted on the effects of intercropping green manures on the production and quality of table tomato. In this sense, the present study was performed with the objective of evaluating if the intercropping of green manures interferes in the production and quality of table tomato. The experiment was conducted in the experimental area of the University Campus of Sinop (UFMT) in the period from March to July 2020. The experimental design was used entirely randomized, with 4 treatments and 4 repetitions. The treatments consisted of single tomato cultivation (T0), and intercropping with green manures (T1), forage peanut (Arachis pintoi), crotalaria (Crotalaria spectabilis), and pork bean (Canavalia ensiformis). The following were evaluated: a) number of fruits per plant - NFP, b) average fruit mass - MMF, c) productivity - P (kg ha-1), d) relative chlorophyll content - TRC, e) total titratable acidity - ATT, f) soluble solids content - SS and g) Ratio - R. There was no effect of intercropping with green manures on NFP, and MMF, but there was a reduction in productivity when the forage peanut was used. The use of forage peanut significantly reduced the values of TRC in the leaves. The values of ATT, TSS and R were not significantly influenced by the green manures. From the results obtained it can be concluded that: a) intercropping tomato with pork bean results in lower fruit yield and lower values for the relative chlorophyll index, b) intercropping tomato with green manures does not interfere in the organoleptic quality of the fruits.
