“…Noda et al . [37] carried out a series of experiments to test the fertilizing potential of matupá compared to other natural fertilizers on plantations of winged bean ( Psophocarpus tetragonolobus (L.) DC. ), and concluded that matupá is more effective than all other natural fertilizers tested including chicken manure and compost from fruit and vegetable remains.…”

The Floating Forest: Traditional Knowledge and Use of Matupá Vegetation Islands by Riverine Peoples of the Central Amazon

Matupás are floating vegetation islands found in floodplain lakes of the central Brazilian Amazon. They form initially from the agglomeration of aquatic vegetation, and through time can accumulate a substrate of organic matter sufficient to grow forest patches of several hectares in area and up to 12 m in height. There is little published information on matupás despite their singular characteristics and importance to local fauna and people. In this study we document the traditional ecological knowledge of riverine populations who live near and interact with matupás. We expected that their knowledge, acquired through long term observations and use in different stages of the matupá life cycle, could help clarify various aspects about the ecology and natural history of these islands that field biologists may not have had the opportunity to observe. Research was carried out in five riverine communities of the Amanã Sustainable Development Reserve (Brazil). Semi-structured interviews were conducted with 45 inhabitants in order to register local understandings of how matupás are formed, biotic/abiotic factors related to their occurrence, the plants and animals that occur on them, their ecological relevance, and local uses. Local people elucidated several little-known aspects about matupá ecology, especially regarding the importance of seasonal dynamics of high/low water for matupás formation and the relevance of these islands for fish populations. Soil from matupás is especially fertile and is frequently gathered for use in vegetable gardens. In some cases, crops are planted directly onto matupás, representing an incipient agricultural experiment that was previously undocumented in the Amazon. Matupás are also considered a strategic habitat for fishing, mainly for arapaima (Arapaima gigas). The systematic study of traditional ecological knowledge proved to be an important tool for understanding this little-known Amazonian landscape.

“…Vários autores (Zapeda, 1971;Meyer et al, 1973;Noda, 1979;Noda & Kerr, 1983;Noda et al, 1984), mencionam que a prática da retirada das inflorescências proporciona um aumento considerável na produção de raízes tuberosas. Zapeda (1971), trabalhando com jicama, relata a necessidade dessa prática para duplicar o rendimento das raízes em termos de tamanho e peso.…”

Development of yam bean or "Feijão-Macuco" plant in a floodplain area.Pachyrrhizus tuberosus, popularly known as yam bean, ("feijão-macuco" or "jacatupé" in portuguese) is one of the tropical food plant species bearing edible tuberous roots. The purpose of this study was to evaluate the plant's growth, correlating the development of the plant parts in the vegetative, flowering, fruiting and tuberous root formation stages, as well as assessing the importance of staking the plants and pruning the inflorescence in the development of the plant and in the yield of tuberous roots. The study was carried out in a Rio Solimões' floodplain area from August 1993 to May 1994, with 1,925 mm of rainfall, 26 o C average temperature and 86.5% relative humidity. The behavior of three genotypes, identified as 1, 2 and 3, which were submitted to four kinds of plant management: with and without staking the plants and with and without pruning the inflorescences. The experimental design was completely randomized blocks in a factorial scheme of 3 x 2 x 2 (genotypes, staking, and inflorescences pruning, respectively) with three replications. Plots measuring 15.5 x 25.0 m were used. The staking treatment increased the plant and stems dry matter weight. Usually there was a steady increase of the above and below ground parts with staking. Growth rates were similar to all genotypes. Staked plants showed a tendency to higher relative growth. The pruning of the inflorescences promoted up to 4.6 fold increase in the tuberous roots weight. In addition to raising the leaves dry matter weight, inflorescence pruning also furthered an increase in the a, b and total chlorophyl grades 160 days after sowing. According to results obtained, it was concluded that staking plants associated with the pruning of the inflorescences improved the development of the "feijão-macuco".
