Development of peach palm (Bactris gasipaes H.B.K.) in mixed cropping systems.
Desenvolvimento da pupunheira (Bactris gasipaes H.B.K.) em sistemas de policultivo: The Amazon region has a great variety of native species with economic potential, notably peach palm. The development of peach palm was monitored in mixed cropping systems treated by application of 30% or 100% of the recommended fertilizer dose and inoculation or not of seedlings wth VA-mycorrhizal fungi. The parameters evaluated were height of the plants at 12 and 18 months, number of shoots/plant at 12 months, diameter of the stem and palm heart production at 18 months. As regards height of the plants and stem diameters, there were significant differences between the treatments with 30% and 100% fertilizer in the two systems. However, within the two fertilization levels, there was no significant difference between the treatments with and without mycorrhiza. There was a significant difference in number of shoots/plant between the two fertilization levels in System 1 only. Although, the difference was not significant, the number of shoots/plant was greater in the treatments with mycorrhiza. The data for palm heart production in the mixed cropping and monoculture systems will be discussed and compared.
