Visando aumentar a produtividade do tomateiro cultivado em sistema orgânico, sob ambiente protegido, montou-se um experimento em esquema fatorial 2 x 2, sendo o primeiro fator cultivares com diferentes hábitos de crescimento: cultivar Pesagro Linha B - crescimento determinado e cultivar Santa Clara - cres-cimento indeterminado; e o segundo fator o número de hastes por planta: 1 haste e 2 hastes. A cultivar Santa Clara obteve maior produção total por planta e maior produção de frutos Extras (maiores que 100 g) por planta. A cultivar Pesagro Linha B obteve maior massa fresca média dos frutos. A condução com duas hastes promoveu maior produção total por planta e maior produção de frutos Extras por planta.
Aiming to increase the productivity of the tomato cultivated in organic system, under protected environment, was mounted an experiment in factorial 2 x 2, being the first factor the cultivate with different habits of growth: cultivate Pesagro Linha B - definitive growth and cultivate Santa Clara - indeterminate growth; and as the second facto r the number of stem for plant: 1 stem and 2 stems. The cultivate Santa Clara got greater total plant production and Extra fruits (bigger that 100 g) plant production. The cultivate Pesagro Linha B got greater average fresh mass of the fruits. The conduction with two stems promoted greater total plant production and high plant production of Extra fruits.

The net primary production of tropical forests and its partitioning between long-lived carbon pools (wood) and shorter-lived pools (leaves, fine roots) are of considerable importance in the global carbon cycle. However, these terms have only been studied at a handful of field sites, and with no consistent calculation methodology. Here we calculate above-ground coarse wood carbon productivity for 104 forest plots in lowland New World humid tropical forests, using a consistent calculation methodology that incorporates corrections for spatial variations in tree-size distributions and wood density, and for census interval length. Mean wood density is found to be lower in more productive forests. We estimate that above-ground coarse wood productivity varies by more than a factor of three (between 1.5 and 5.5 Mg C ha−1 a−1) across the Neotropical plots, with a mean value of 3.1 Mg C ha−1 a−1. There appear to be no obvious relationships between wood productivity and rainfall, dry season length or sunshine, but there is some hint of increased productivity at lower temperatures. There is, however, also strong evidence for a positive relationship between wood productivity and soil fertility. Fertile soils tend to become more common towards the Andes and at slightly higher than average elevations, so the apparent temperature/productivity relationship is probably not a direct one. Coarse wood productivity accounts for only a fraction of overall tropical forest net primary productivity, but the available data indicate that it is approximately proportional to total above-ground productivity. We speculate that the large variation in wood productivity is unlikely to directly imply an equivalent variation in gross primary production. Instead a shifting balance in carbon allocation between respiration, wood carbon and fine root production seems the more likely explanation.
