Balance of the solar radiation in agroforestry systems in Central Amazonia. Repositório Alice
CORREIA, F. W. S.; MACEDO, J. L. V.; SCHROTH, G..
Micrometerological observations have been used to study the radiation balance over recultivation areas in SHIFT agroforestry systems in Manaus-AM (Brasil). The radiation balance was compared with measurements obtained in a adjacent forest (Ducke Reserve).

Evaluation of manioc (Manihot esculenta Crantz) cultivation in mixed cropping systems. Repositório Alice
MARTINS, G. C.; MACEDO, J. L. V.; ARAUJO, R. C..
Avaliação da cultura da mandioca (Manihot esculenta Crantz) em sistema e policultivo: Yields and survival rates will be presented for three manioc cultivars(Pao IM 226, Vinagre IM 157 and Mandioca IM 116), planted between the rows in two mixed cropping systems, which were treated by application of 30% or 100% of the recommended fertilizer dose and inoculation or not with mycorrhizal fungi spores. With regard to yield, there is no statistically significant difference between the treatments viewed in isolation. However, there are statistically significant differences between the cultivars Pao (10.6 tons/ha) and Vinagre (5.5 tons/ha) in system 2; between 100% fertilization (5.2 tons/ha) and 30% fertilization (3.7 tons/ha) in system 3, and between the Pao...

Evaluation of the nutrient contents of cupuacu (Theobroma grandiflorum) as a function of different levels of fertilizers. Repositório Alice
MACEDO, J. L. V.; FIGUEIREDO, N. N.; LEHMANN, J.; CRAVO, M. S..
Study to evaluate of cupuacu in an agroforestry system ((cupuacu, pupunha, seringueira-rubber tree, mamao-papaya, pueraria) with different fertilizer levels, in the Manaus-AM (Brasil). Comparing the agre of the leaves, the largest concentration of N were found in the intermediate leaves, and the lowest concentration were found in the old leaves. The contents of P and K decreased with the age of the leaf. For the new and intermediate leaves, the lowest concentration of P was observed in the treatment 30% N. The P contents were not influenced by the different fertilization levels.

Evaluation of the nutrients contents of cupuassu (Theobroma grandiflorum) as a function of different levels of fertilizers. Repositório Alice
FIGUEIREDO, N. N.; MACEDO, J. L. V.; CRAVO, M. D. S.; LEHMANN, J..
Evaluation cupuassu (T. grandiflorum) in a agroforestry system (cupuassu, T. grandiflorum, rubber tree, Hevea spp, and peach palm, Bactris gasipaes - for palm heart) with different fertilizer (N, P, K, Ca and MG) levels. The concentrations of N, P and K varied as a function of the age of the leaves with the largest concentrations found in new leaves. With relation to the age of the leaves (new leaves, intermediary and old) it was observed that the intermediary leaf would be the best alternative for the plant diagnosis, because the variation was lowest. The highest nutrient concentrations were found in the samples collected immediately after fertilization and the lowest after fruit harvest. This suggest that in order to verify the effect of fertilization,...

Nutrient requirements of Amazonian tree crops - consequences for agroforestry use and management. Repositório Alice
ELIAS, M. E. A.; SCHROTH, G.; MACEDO, J. L. V.; MOTA, M. S..
We studied soil fertility and plant nutrition in multi-strata agroforestry systems with several perennial crop species at four fertilization levels to obtain information on growth-limiting nutrients and to develop optimum sampling schemes for foliar analysis for the different species: peach palm (pupunha), cupuacu, Brazil nut (castanha-do-Para), annatto (urucu) and the cover crop Pueraria phaseoloides.

Production of urucum (Bixa orellana L.) inoculated with by micorrhizal fungi in mixed cultivation systems. Repositório Alice
NORMANDO, M. C. S.; IDCZAK, E.; MARTINS, G. C.; MACEDO, J. L. V..
Produção de urucum (Bixa orelana L.) inoculado com fungos micorrízicos em sistemas de policultivo: The urucum seedlings were inoculated with VA-mycorrhizal fungi in the nursery, on non-sterilized substrate. Root colonization in the nursery before planting into the field was statistically higher for inoculated plants (59% + ou - 11%) than for non-inoculated plants (31% + ou - 20%). After some time in the field, root colonization was the same in the different treatment regimes. However, the highest percentage colonization was found in the plants which received only 30% of the recommended fertilizer dose. The plant height in the different treatment regimes did not differ statistically. There was a significant difference in stem diameter between the two...
