Resumo
Melhores condições de higiene, diminuição na incidência de doenças do solo e alternativa para a falta de espaço são as principais vantagens que o produtor encontra na utilização de recipientes para o cultivo de hortaliças em estufas. Esse trabalho teve como objetivo avaliar diferentes tipos de recipientes com substrato de fibra de coco para o cultivo de melão rendilhado, com uso da fertirrigação sob ambiente protegido. O ensaio foi conduzido de março a junho de 2006 na área experimental da Fazenda de Ensino, Pesquisa e Extensão da Faculdade de Engenharia – UNESP, Campus de Ilha Solteira – SP. Os tratamentos constaram de quatro recipientes (Calha com capilaridade, Calha com gotejamento, Vaso pequeno e Vaso grande) e dois híbridos de melão rendilhado (Laurent e Maxim). O delineamento experimental adotado foi o de blocos ao acaso com 4 repetições. Cada parcela foi constituída por 12 plantas, sendo 6 plantas de cada híbrido, com espaçamento de 1,3m entre fileiras e 0,5m entre plantas. Após as avaliações, os dados foram submetidos à análise de variância e teste de tukey, ao nível de 5% de probabilidade, com auxílio do programa computacional Sanest. Avaliou-se condutividade elétrica (CE), número de folhas, altura das plantas, número médio de frutos por planta, número de frutos totais, massa média de frutos, produtividade total, produção de frutos graúdos, médios e miúdos, diagnose foliar (macro e micro nutrientes) e teor de sólidos solúveis totais (SST). Os recipientes vaso grande, vaso pequeno e calha com gotejamento proporcionaram valores semelhantes e superiores para número de frutos por planta, número de frutos totais, produção de frutos graúdos e massa média, porém o vaso grande apresentou maior produtividade total, enquanto a calha com capilaridade proporcionou os menores valores para quase todas as avaliações mostrando-se inferior aos...(Resumo completo,
Better hygiene conditions, less incidence of soil diseases and alternative to lack of space are the main advantages the producer finds in greenhouses production of green vegetables. The aim of this trial was to evaluate different kinds of trays with coconut fiber substratum to produce net melons with fertirrigation usage under protected environment. The experimet was conducted from March and June of 2006, at the Experimental Station of UNESP, Campus of Ilha Solteira, São Paulo State, Brazil. The treatments consisted of 4 trays (Capillarity gutter, drip gutter, larger sized vase and smaller sized vase) and two net-melon hybrids (Laurent and Maxim). It was adopted the randomize blocks design with four replications. There were 6 plants of each hybrid, in the spacing of 1.2m between rows and 0.5m between plants. The data had been submitted to “Sanest” statistics program and the “Tukey” test, with 5% probability. It was evaluated the electrical conductivity (CE), leave numbers, plants height, average fruit numbers by plants, fruit numbers by area, average mass of fruits, productivity, leaf diagnosis (macro and micronutrients) and solid soluble content rate (SST). Similar or superior values for larger sized fruits production and average mass was shown with larger sized vase, smaller sized vase and drip gutter, however, superior value for productivity presented larger sized vase, meanwhile inferior values was shown with capillarity gutter for the same evaluations. The tow hybrids the Maxim hybrid was pointed as superior through average mass of fruits and larger sized fruits production, while the Laurent, presented greater plants height and solid soluble content, although, of both hybrids are considered as excellent quality.
