An agroforestry study (Project STAG - Soils, Trees And Grass) to identify problems in the development of stable silvopastoral systems in a subtropical environment was run over 4.6 years at the Samford Pasture Research Station, NW of Brisbane, Queensland. Eucalyptus grandis was planted in a Nelder fan design, with tree stand densities ranging from 42 to 3580 stems/ha, into a Setaria dominated pasture. Growth of trees improved with increasing stand density until competition for water and light outweighted the benefits of mutual protection. For most parameters measured, there was a change in magnitude with time away from the centre of the wheel like ripples in a pond. At 1.5 years the maximum above-ground individual tree biomass was at a stocking of 3580 stems/ha. At 2, 2.5, 3, 3.5 and 4.6 years the maxima were at 1140, 595, 305, 158 and 82 stems/ha respectively. Trees interacted with each other, even at low stand densities. Pasture production also showed a ripple effect, being little affected by the trees at age 0.5 years, but substantially reduced after 1.5 years at stand densities >1000 stems/ha. By age 3.5 years, pasture production was reduced at stand densities >300 stems/ha. At this age and stocking, tree growth, taper, crown dimensions and health were also optimal. It is concluded that trees and pasture can be successfully grown together to provide substantial production from each, but that a thinning regime would be required to maintain an optimum balance between the two components of this system.

O Banco de Germoplasma de cupuaçu da Embrapa Amazônia Ocidental foi formado a partir de 1984 e apresenta 247 acessos coletados nos municípios do Amazonas e Região Bragantina, Pará. Encontra-se instalado no Km 29 da rodovia AM-010, Manaus, AM, no espaçamento de 7m x 7m. Os acessos oriundos de propagação vegetativa estão plantados com três plantas por parcela e quatro repetições e os multiplicados por sementes com cinco plantas por parcela e quatro repetições. Devido a incidência da doença vassoura-de-bruxa houve perdas de plantas em algumas parcelas. Cada matriz recebe um código alfanumérico de introdução no BAG. |
