“…Estudos tem mostrado eficiência no rendimento agronômico e na qualidade de cultivares e híbridos de tomate em cultivo protegido sob sombreamento em relação ao cultivo a céu aberto em outras regiões do Brasil (Radin et al, 2003;Carrijo et al, 2004;Caliman et al, 2005).…”

The northern region of Minas Gerais is marked by summers of high light intensity, which prevents the cultivation of some vegetables in this season. To evaluate the agronomic performance and the quality of the tomato cultivation under different shading levels, we conducted in 11/2009 at 02/2010 an experiment in the company Qualihort Seeds Ltd located in the municipality of Nova Porterinha, Minas Gerais. The experiment was arranged in randomized blocks in a 2 x 4 factorial design (two hybrids -Dominator and Giovanna -and four shading levels: 0%, 18%, 30% and 50%) with four replications. The hybrid Dominador was superior to the Giovanna in plant height, fruit number and fruit number per plant. The environments with 50 and 30% shading promoted higher plants. A região norte de Minas Gerais é marcada por um verão de alta intensidade luminosa, o que consequentemente inviabiliza o cultivo de algumas hortaliças nessa época. Objetivando avaliar o rendimento agronômico e a qualidade do cultivo do tomateiro sob diferentes níveis de sombreamento, conduziu-se, de novembro 2009 a fevereiro de 2010, um experimento na empresa Qualihort Sementes Ltda, localizada na cidade de Nova Porterinha, Minas Gerais. O delineamento experimental utilizado foi em blocos casualizados em esquema fatorial 2 x 4, com 4 repetições, sendo dois híbridos (Dominador e Giovanna) e quatro porcentagens de sombreamento (0%, 18%, 30% e 50%). O híbrido Dominador foi superior ao Giovanna em relação a altura da planta, número total de frutos, número de frutos por planta. O sombreamento promoveu aumento linear na altura das plantas. A produtividade total, comercial e altura das plantas foram maiores quando se utilizou 50% de sombreamento. As diferentes porcentagens de sombreamento não alteraram significativamente as características avaliadas, pH, Sólidos Solúveis Totais (SST), Acidez Total Titulável (ATT) e Relação Sólidos Solúveis/Acidez Titulável (RSA). Observou-se maior valor médio de pH nos frutos do híbrido Dominador, e maior valor médio de SST no 'Giovanna'. O híbrido Dominador e os ambientes sombreados condicionaram melhores desempenhos agronômicos para o tomateiro no Norte de Minas Gerais, com destaque para a tela de 50% de sombreamento. Porém, o sombreamento das plantas não influenciou a qualidade dos frutos do tomateiro. Palavras-chave:Licopersicon esculentum Mill., intensidade luminosa, ambiente protegido, cultivares.

Four experiments were carried out at the São Paulo State University, Brazil, with the aim of determining the agronomic viability of intercropping tomato and lettuce, under greenhouse conditions. The studied intercropping systems were established by transplanting lettuce at 0, 10, 20 and 30 days after transplanting (DAT) tomato and by transplanting tomato at 0, 10, 20 and 30 DAT lettuce. Intercropped tomato and lettuce were evaluated during two seasons and compared to their sole cropping. The experimental design was a randomized complete block with nine treatments. The productivity and the classification of the tomato fruits were not influenced by having lettuce intercropped with it, but lettuce production was lowered when tomato was intercropped with it. The longer the delay in lettuce transplanting, the greater the reduction in its productivity. There was an effect of cropping season on the extent of the agronomic advantage of intercropping over sole cropping. In the first cropping season, intercropping established by transplanting lettuce during the interval between 30 days before up to 20 DAT tomato yielded land use efficiency (LUE) indices of 1.63 to 2.22. In the second period, intercropping established with the transplanting of lettuce up to 30 days before tomato yielded LUE indices of 1.57 to 2.05.

ABSTRACT:The seedlings production is an essential part for vegetables production. Thus, this study aimed to evaluate the environment, the substrates and the containers in the development of tomato seedlings, cv. Santa crus Kada Gigante, in Aquidauana -MS, Brazil region, from October to November, 2008. Polystyrene trays with 72; 128 and 200 cells, filled with four substrates (soil; Plantmax ® ; coconut fiber and vermiculite) were tested in three protected environments (greenhouse; screened with Sombrite ® and screened with Aluminet ® ). The experimental design was completely randomized, factorial scheme 3x4 (three trays x four substrates), with four replications, being analyzed individual variance analysis and joint analysis for the environments. The environment with screens (Sombrite ® and Aluminet ® ), the trays with 72 cells and the vermiculite produced better results.
