Resumo(s)
Portugal é um dos maiores produtores de tomate na União Europeia, sendo a região do Oeste a principal zona de produção do país. No entanto, é importante procurar estratégias que aumentem a produtividade, garantindo simultaneamente um impacto ambiental reduzido. Este trabalho teve como objetivo avaliar o efeito do produto comercial BIOCEL (produto formulado com diversos microrganismos, hormonas de crescimento e uma parte mineral constituída por zeolita) sobre o desenvolvimento vegetativo e a produtividade do tomateiro, em cultura protegida, assim como o seu potencial impacto na incidência de pragas e na presença de mirídeos predadores. Para tal, foi efetuado um ensaio durante a primeira campanha de tomate em cultura protegida (de fevereiro a junho) em 2025. O produto foi aplicado no momento da plantação, numa dose de cerca de 50 g por cada duas plantas, comparando-se vários parâmetros como altura das plantas, número de nós, número de cachos, número de frutos/cacho e peso dos frutos. Adicionalmente, também se registou a presença de traça-do-tomateiro (Phthorimaea absoluta), mosquinhas-brancas e larvas-mineiras, assim como a presença de mirídeos. Os resultados evidenciaram que a aplicação de BIOCEL teve um efeito significativo no crescimento e produtividade do tomateiro, em cultura protegida, nomeadamente num maior número de cachos por planta, maior número de frutos por cacho e maior peso médio dos frutos, traduzindo-se num acréscimo de produtividade de 24,2%. Por outro lado, a aplicação do BIOCEL não afetou a incidência das principais pragas do tomateiro, nomeadamente traça-do-tomateiro, larva-mineira e mosquinhabranca, nem influenciou a atratividade das plantas em relação a mirídeos predadores.
Portugal is one of the largest tomato producers in the European Union, with the Oeste region being the main production area in the country. However, it is important to seek strategies that increase productivity while simultaneously ensuring a reduced environmental impact. This study aimed to evaluate the effect of the commercial product BIOCEL (a product formulated with various microorganisms, growth hormones, and a mineral component consisting of zeolite) on the vegetative development and productivity of tomato plants, as well as its potential impact on pest incidence and the presence of predatory beneficial insects. For this purpose, a trial was conducted during the first protected tomato crop cycle (from February to June) in 2025. The product was applied at planting, and several parameters were compared, including plant height, number of nodes, number of clusters, number of fruits/cluster, and fruit weight. Additionally, the presence of tomato South American moth (Phthorimaea absoluta), whitefly, and leaf-miners was recorded, as well as the presence of mirid bugs. The results showed that the application of BIOCEL had a significant effect on the growth and productivity of tomato plants grown under protected conditions, namely a higher number of clusters per plant, a greater number of fruits per cluster, and a higher average fruit weight, resulting in a 24.2% increase in yield. On the other hand, the application of BIOCEL did not affect the incidence of the main tomato pests—specifically the tomato leafminer, leaf-mining larvae, and whiteflies—nor did it influence the attractiveness of the plants to predatory mirids.
