Resumo: | Substrate-filled pots are growing systems commonly used for vegetable farming. However, few are the studies available relating them to mini-watermelon cultivation. Our study presents a growing system using substrate-filled troughs and leachate recirculation as a low-cost and less environmentally harmful soilless cultivation system for mini-watermelons. For a growing system to be viable and provide high fruit yield and quality, several aspects must be studied, including substrate physical properties and reuse potential in successive crops, besides plant management-related aspects. Therefore, our goal was to evaluate the effects of a trough system and substrate reuse on changes in the properties of raw rice husk and on fruit yield and quality for mini-watermelons at different stem training. To this purpose, two trials were conducted using nutrient solution recirculation systems. In the first, we evaluated the effects of pot and trough systems. In the second, first- and second-use substrates were compared in the trough system. In both trials, one and two-stem training systems were analyzed. The results of the first trial show that the trough system had a greater positive impact on substrate water holding capacity (WHC), which increased from 7.9 to 15.6%, while the pots increased substrate WHC only to 11.2%. However, both systems neither affected fruit yield (8 kg/m² on average) nor fruit quality. The two-stem training promoted higher fruit yields (4.2 kg/plant) and contents of total soluble solids - TSS (11.4 °Brix) but did not affect average fruit weight. Moreover, the one-stem training provided higher fruit number (7.3 fruits/m²) and fruit yield (9.7 kg/m²). In the second trial, the reused substrate showed a higher WHC (12.4%) than the one used for the first time (9.9%). The reused substrate also provided better results in terms of fruit yield and quality (5.9 fruits/m², 5.3 kg/m², and 10.5o Brix). In the second trial, two-stem training also increased average fruit weight, and hence yields per plant. Nevertheless, the stem number did not affect fruit number per plant, fruit yield per square meter, and fruit quality. |

Este trabalho introduz o sistema de calhas preenchidas com substrato e com recirculação do lixiviado para esta cultura, como uma alternativa de baixo custo e menor impacto ambiental. Para que o sistema seja viável e possibilite boa produtividade e qualidade dos frutos, vários aspectos devem ser estudados, entre estes, as características físicas do substrato, a possibilidade de reutilizá-lo em cultivos sucessivos e o manejo adequado das plantas. O objetivo do trabalho foi estudar o efeito do sistema de cultivo e da reutilização sobre as alterações das propriedades do substrato de casca de arroz in natura, a produção e a qualidade de frutos de plantas de minimelancia cultivadas com diferentes números de hastes. Dois experimentos, empregando sistemas com recirculação da solução nutritiva, foram realizados. No primeiro, as plantas foram cultivadas em vasos e calhas. No segundo, foram comparados substratos de primeiro e segundo uso no cultivo em calhas. Em ambos os experimentos, foi estudada a condução das plantas em uma e duas hastes. Em relação aos resultados obtidos, no primeiro experimento, o sistema de calhas teve maior impacto positivo sobre as características físicas do substrato, cuja capacidade de retenção de água (CRA) passou do valor inicial de 7,9% para 15,6% ao final, enquanto que nos vasos se elevou a 11,2%. Porém, os sistemas não afetaram a produtividade, com média de 8 kg/m², e a qualidade dos frutos. As plantas de duas hastes apresentaram maior produção de frutos (4,2 kg/planta), com maior conteúdo de sólidos solúveis totais - SST (11,4 oBrix), ainda que sem efeito sobre o peso médio. Porém, as plantas de uma haste apresentaram maior número (7,3 frutos/m²) e produção de frutos (9,7 kg/m²). No segundo experimento, o substrato de 2º uso apresentou maior CRA (12,4%) que o substrato novo (9,9%) e proporcionou melhores resultados de produtividade e qualidade para a maioria das variáveis estudadas, obtendo-se 5,9 frutos e 5,3 kg/m², com SST de 10,5 oBrix. As plantas de duas hastes tiveram resultados melhores de peso médio de frutos e, consequentemente, de produção por planta do que as plantas de uma haste, sem efeitos sobre o número de frutos/planta, o rendimento por m2 e a qualidade.UEL2021-02-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3805910.5433/1679-0359.2021v42n2p471Semina: Ciências Agrárias; Vol. 42 No. 2 (2021); 471-486Semina: Ciências Agrárias; v. 42 n. 2 (2021); 471-4861679-03591676-546Xreponame:Semina.
