    Magnus grano: Maximum quality in bean size of conilon coffee
    (Crop Breeding and Applied Biotechnology, 2024-08-25) Sousa, Priscila Gonçalves Figueiredo de; Vieira, Henrique Duarte; Partelli, Fábio Luiz; Santos, Eileen Azevedo; Viana, Alexandre Pio; Souza, Rosenilda de; Oliosi, Gleison; Correia, Laísa Zanelato; Acha, Amanda Justino
    Cultivar Magnus grano is made up of five genotypes that were selected by coffee growers in the state of Espírito Santo, Brazil. The cultivar shows good adaptation to growing conditions, high yield potential, and the largest beans among the studied genotypes.

    Can season and intercropping Conilon coffee favor predatory ant species?

    Conilon coffee (Coffea canephora Pierre ex A. Froehner) is an important crop in Brazil, and this culture is widely grown in Espírito Santo State. Intercropping this species has been adopted for better use, profitability, and sustainability of the cultivated area. Intercropping provides higher shading and may favor edaphic fauna that plays an important ecological function in the soil. Ants are part of the edaphic meso - and macrofauna, considered ecosystem engineers and actively participate in pest predation. The goal of the study was to evaluate predatory ant richness in Conilon coffee in monoculture and intercropped with teak or Australian cedar. Furthermore, the influence of these crops on the richness of predator ant communities in the dry (winter) and rainy (summer) seasons was analyzed. The study was conducted in the municipality of Sooretama, northern Espírito Santo State (Brazil) using pitfall soil traps. Ant communities were analyzed with their distribution in trophic guilds. The richness of predatory ants (predatory and generalist omnivore predatory ant species) was studied in Conilon coffee in monoculture and intercropped with teak (Tectona grandis L.f.) and with Australian cedar (Toona ciliata M. Roemer), in the dry (winter) and wet (summer) seasons. A total of 49 ant species were collected, 29 predatory and 15 generalist omnivore predatory ant species were identified, and 16 ant species were recorded for the first time in Espírito Santo State. Conilon coffee cropping systems did not affect the richness of predatory or generalist omnivore predatory ant species, however, summer favored the occurrence of total predatory ants (generalist omnivore + predators); intercropping Conilon coffee did not favor predatory ants. The presence of predatory species is important for natural pest control, consequently improving crop sustainability. However, new research must be done to evaluate other Conilon coffee intercropping for a longer period.

    Water requirement satisfaction index for coffee (Coffea canephora) crops in Western Amazon
    (Departamento de Engenharia Agrícola - UFCG, 2024-07-30) José, Jefferson V.; Pereira, Lívia B.; Souza, Moisés D.; Leite, Kelly N.; Santos, Otávio N. A.; Santos, Lucas C.
    Water balance is a tool that has various applications in agriculture, including assessing whether an environment is suitable for growing a specific crop by providing information on how water resources function in the system. This information is essential for determining whether the available water satisfies the crop’s demand. Thus, the objective of this work was to calculate the water balance of Typic Hapludults for growing coffee (Coffea canephora) crops in Cruzeiro do Sul, Acre, Brazil, using a 36-year historical series to assess the potential and limitation of the crop according to the water availability. The results showed that coffee crops are, in general, suitable for growing in the study region. Water deficit and water surplus periods are well-defined, from April to August and September to March, respectively. Flowering was the only stage of coffee crops that coincides with the water deficit period in the region; thus, irrigation is necessary to prevent compromising this stage and fruit development. The Water Requirement Satisfaction Index (WRSI), calculated on a monthly basis, indicates a low climate risk for coffee crops in the region. However, when calculated on a daily basis, the WRSI shows a medium to high climate risk for coffee crops in several periods. The WRSI proved to be an adequate tool for assisting in decision-making regarding the adoption of irrigation.
