Pepper (Capsicum spp.) is a high-yield commodity in Togo(Maatman, and the Al., 2011). The local pepper varieties are preferred and widely consumed, but there are no commercial seeds available in the market, or a Capsicum breeding program in Togo. Farmers themselves perpetuate the local varieties by collecting seeds of commercial fruits for the next sowing. Through a participatory research approach, this project aims at: 1) Selecting two local red pepper varieties and two bell pepper varieties th

Peppers of the Capsicum genus are cultivated in every Brazilian state, especially in Goiás, Minas Gerais, São Paulo, Ceará, Bahia, and Sergipe states, having a total estimated area of 5,000 hectares and a production of about 75,000 tons per year. The cultivation of peppers and bell peppers in Brazil has a strong family base and social importance since this activity is carried out predominantly by smallholder farmers and it is the main source of income for such families. Despite chili pepper bein ...

Bananas are one of Brazil's main agricultural products, having great economical significance. With a production reaching over five million tons annually, the fruit is a source of food for millions of people around the world. However, the plantations have been facing diseases and plagues which reduce the productive cycle once the local farmers are oblivious to certain agricultural practices. In the Amazon, the need to increase the crops is hindered by the lack of quality genetic strains for disse

The ‘cipó-titica’ vine (Heterops flexuosa) is a non-timber forest product of economical importance in Amapá. Its long and resistant aerial roots have historically been used for crafting furniture, utensils and handcrafts. The project will be situated in Nova Canaã settling, at Porto Grande municipality (Amapá) and aims to evaluate cipó-titica plants density in the forest in order to identify phorophytes (tree species that host the vine) and thus determine the rate of growth and emission of ne

The Amapá state has extensive forests and savannas, which are important carbon stocks being negatively affected due to agricultural, forestry and industrial activities. Thus the project aims to develop a methodology applicable to the entire State of Amapá, aiming to reach all types of existing vegetation, being the basis for estimates of forest biomass and the quantification of carbon stocks, in addition to enabling the monitoring of changes caused on biomass due to the economic activities de

Oriental Amazon Embrapa has an ample research history in various native essences of the amazonian ecosystem, including the big leaf mahogany ( Swietenia macrophylla King). However, the formation of a research network focused in studies regarding the interaction between the mahogany shoot borer ( Hypsipyla grandella Zeller), its natural enemies and its most important host remains a demand to be fulfilled. The damage caused by this insect consists of the destruction of the tree's ter ...

The cultivation of winter forage crops such as Italian ryegrass ( Lolium multiflorum) and velvet grass ( Holcus lanatus) is of extreme importance for increasing the productivity and efficiency of livestock production in the South Region and part of the Southeast Region of Brazil. However, there are few cultivars for use by farmers. The problem focused in this project is the lack of improved cultivars of temperate forage grasses, productive and adapted to the Brazilian conditions. T ...

The manual harvest of pepper fruits is difficult mostly due to the plants' low heights and the fruit's pungency, which causes irritation and burns the hands of harvesters. Such aspects partly explain the scarcity of labor for the pepper harvest. In addition, in the Brazilian and international market there are no jalapeño cultivars developed for mechanized harvesting. Therefore, this project aims at the development of new jalapeño cultivars adapted to mechanized harvest - with suitable plant arch ...
