Title A name given to the resource Incidência de pragas e desempenho produtivo de tomateiro orgânico em monocultivo e policultivo Incidence of pests and organic tomato crop productive performance in monoculture and polyculture Creator An entity primarily responsible for making the resource Flávia B Gomes, Leidiane de J Fortunato, Anália Lúcia V Pacheco, Letícia H de Azevedo, Narimã Freitas, Sérgio K Homma Description An account of the resource O objetivo com este experimento foi comparar o cultivo do tomateiro em monocultivo e policultivo (consórcio com coentro, cravo-de-defunto e o sorgo como cultura circundante) no sistema de produção orgânico, em relação à incidência de pragas, rendimento e qualidade de frutos. Foram avaliados a incidência de tripes, plantas e frutos com sintomas de virose (%), frutos broqueados por Neoleucinodes elegantalis (%), a produtividade total e comercial, o número total e comercial de frutos, o peso médio e o diâmetro dos frutos comercializáveis, o teor de sólidos solúveis totais (SST), o teor de acidez total titulável (ATT) e a relação SST/ATT. No policultivo ocorreu menor número de tripes e, consequentemente, menor percentagem de plantas e frutos com sintomas da virose. A incidência de broqueamento de frutos por N. elegantalis também foi menor em policultivo. A produtividade total e o número total de frutos no monocultivo foram superiores à do policultivo. Porém, a produtividade comercial foi igual nos dois sistemas de cultivo. O diâmetro dos frutos não diferiu entre os tratamentos, mas o peso médio dos frutos oriundos do monocultivo foi maior. Os frutos do policultivo apresentaram maiores teores de SST e ATT e a relação SST/ATT não diferiu entre os tratamentos. Assim, reforça-se a importância da diversidade vegetal no manejo de pragas, sendo necessários novos estudos que permitam definir melhor arranjo espacial das plantas para manter sua atuação na regulação de insetos-praga e qualidade dos frutos sem interferir na produtividade do tomateiro.The tomato crop in monoculture and polyculture (intercropping with coriander and marigold and sorghum as surrounding crop) were compared in organic system of production, in relation to incidence of pests, yield and quality of fruits. We evaluated the incidence of thrips, the plants and fruits with symptoms of viral disease (%), damaged fruits by Neoleucinodes elegantalis (%), total and commercial yield, total number of fruits, number of marketable fruits, fruit average weight, fruit diameter, total soluble solids (TSS) content, total titratable acidity (TTA) and relation TSS/TTA. In polyculture, a lower incidence of thrips was noticed and, consequently, a lower percentage of plants and fruits with symptoms of viral disease was recorded. The incidence of drilling by N. elegantalis was also lower in the tomatoes in polyculture. The total yield and the total number of fruits in monoculture was higher than in the polyculture. However, the marketable yield was similar in both crop systems and the number of marketable fruits was higher in polyculture. The fruit diameter was not different between treatments, but the total fruit average weight from the monoculture was higher. The fruits of polyculture showed higher content of TSS and TTA and the relation TSS/TTA did not differ between treatments. Thus, it reinforces the importance of plant diversity in pest management, requiring new studies to define a better spatial arrangement of plants to maintain its performance in the regulation of insect pests without interferring on the yield of tomato crop.
