Agronomic yield and quality of industrial tomatoes under NPK doses

ABSTRACT High doses of nitrogen, phosphorus and potassium in irrigated systems may lead to an increase in the productivity of industrial tomatoes, but may also alter the final quality of the fruits. The objective of this was to evaluate the agronomic yield and post-harvest quality of industrial toma...

description ABSTRACT High doses of nitrogen, phosphorus and potassium in irrigated systems may lead to an increase in the productivity of industrial tomatoes, but may also alter the final quality of the fruits. The objective of this was to evaluate the agronomic yield and post-harvest quality of industrial tomatoes, under NPK doses for climatic conditions of Northern Minas Gerais state, Brazil. The study was conducted in the city of Jaíba, MG, Brazil, in randomized block design with four repetitions in a 3 x 3 factorial scheme, consisting of three doses of N (90, 135 and 180 kg ha-1), of P (270, 405 and 540 kg ha-1) and of K (225, 337 and 450 kg ha-1), corresponding to 50, 75 and 100% of the fertilization recommendation; and three tomato hybrids: BRS Sena, Heinz 9553 and BHN 0574. The following variables were evaluated: number of bunches, number and weight of fruits, productivity and fertilizer efficiency index; besides the physico-chemical characteristics: firmness, soluble solids concentration, pH and pulp industrial yield. The hybrid Heinz 9553 showed higher weight, number of fruits, productivity and industrial yield at doses of 75 and 100% of NPK recommendation. The fertilizer doses did not interfere on the soluble solids, pH and fruit firmness of the three hybrids. The hybrid BRS Sena was not influenced by the increase of NPK and there was lower weight, number of fruits, productivity and fertilization efficiency. The hybrid BHN and Heinz hybrids can be indicated for cultivation at doses of 100 and 75% of NPK recommendation, because they promote higher agronomic yield and do not alter the post-harvest quality of the tomatoes.
