Item Can season and intercropping Conilon coffee favor predatory ant species?(Universidade Federal de Lavras, 2024-06-18) Martins, David dos Santos; Fornazier, Maurício José; Abonizio-Santos, Marlina Ribeiro; Guarçoni, Rogério Carvalho; Teixeira, Alex Fabian Rabelo; Magalhães, Fabrício Severo; Souza-Campana, Débora Rodrigues; Maria Santina de Castro, Maria Santina de CastroConilon 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.Item Agronomic performance and productivity of Arabica coffee intercropped with timber species(Universidade Federal de Viçosa, 2023-04-14) Freitas, Ana Flávia de; Fonseca, Arley José; Volpato, Margarete Marin Lordelo; Carvalho, Gladyston Rodrigues; Venturin, Regis Pereira; Silva, Vânia AparecidaThe insertion of the tree component in coffee production is a strategy from an economic and environmental perspective. Thus, the objective of this study was to evaluate the temporal influence on the agronomic and productive performance of the coffee crop under the interference of different tree species as a function of spacing. The experiment was set in the municipality of Santo Antônio de Amparo-MG, in 2012, and conducted in a randomized block design with four replications. The treatments were: cultivar ‘Catuai Vermelho IAC 99’ in monoculture (3.40 m x 0.65 m) and intercropped with African mahogany, teak and pink cedar, in two spacings (9 x 13.6 m and 18 x 13.6 m), in coffee rows. Three coffee rows were fixed between rows, totaling 13.6 m. The following variables were evaluated: height (m), stem diameter (cm), crown diameter (m), productivity (bags ha-1) and yield (l/sc) for coffee. From the evaluations, there is a significant effect of height, productivity and yield for the coffee crop. The system intercropped with tree species did not influence coffee productivity and yield until the 3rd harvest and, for the 5th harvest, intercropping with mahogany favored productivity, although the accumulated productivity did not show any treatment effect.Item Productivity and beverage sensory quality of arabica coffee intercropped with timber species(Empresa Brasileira de Pesquisa Agropecuária - Embrapa, 2020) Freitas, Ana Flávia de; Nadaleti, Denis Henrique Silva; Silveira, Helbert Rezende de Oliveira; Carvalho, Gladyston Rodrigues; Venturin, Regis Pereira; Silva, Vânia AparecidaThe objective of this work was to evaluate the productivity and beverage sensory quality of arabica coffee under the influence of tree species cultivated at different spacings. The experiment was set in 2012, in the municipality of Santo Antônio do Amparo, in the state of Minas Gerais, Brazil. A randomized complete block design was carried out with four replicates and seven treatments, as follows: Catuaí Vermelho IAC 99 Coffea arábica in monoculture (3.40x0.65 m); and this cultivar intercropped at two spacings (9.0x13.6 and 18.0x13.6 m) in the coffee row ‒ either with African mahogany (Khaya ivorensis), teak (Tectona grandis), or pink cedar (Acrocarpus fraxinifolius). Three coffee rows were fixed between rows, totaling 13.6 m between the wooded rows. Productivity, sensory analysis (cup test), and content analysis of sensory attributes were evaluated in the 2017 and 2018 crop years. The treatments and years of harvest influenced productivity. The sensory analysis was positive for coffee intercropped with African mahogany and teak, in 2018. Sensory attributes and nuances are modified by the Years of harvest. Arabica coffee plants intercropped with African mahogany show a superior productivity, regardless of the spacing between species, as well as a higher sensory quality in the 2018 harvest.Item Impactos da deficiência hídrica nas respostas ecofisiológicas e espectrais do cafeeiro consorciado com espécies madeireiras(Editora UFLA, 2016-07) Silveira, Helbert Rezende de Oliveira; Santos, Meline de Oliveira; Silva, Vânia Aparecida; Venturin, Regis Pereira; Volpato, Margarete Marin Lordelo; Dantas, Mayara Fontes; Carvalho, Gladyston Rodrigues; Setotaw, Tesfahun Alemu; Moreira, Filipe Chaves; Barbosa, João Paulo Rodrigues Alves Delfino; Resende, Mário Lúcio Vilela deObjetivou-se, nesse estudo, avaliar o efeito do déficit hídrico nas respostas espectrais e ecofisiológicas de cafeeiros consorciados com madeireiras. A cultivar Catuaí Vermelho 99 foi plantada em monocultivo e consorciada com as arbóreas mogno-africano, teca e acrocarpo, distribuídas em dois espaçamentos (9 x 13,6 e 18 x 13,6 m), na linha dos cafeeiros. As avaliações de crescimento das arbóreas e do cafeeiro foram realizadas aos 25 meses após o plantio. As avaliações espectrais e ecofisiológicas nos cafeeiros foram realizadas em quatro épocas (junho, agosto, setembro e dezembro de 2014). O acrocarpo apresentou maior altura, diâmetro de copa e caule. Não houve diferenças entre o crescimento dos cafeeiros consorciados e monocultivo. As diferenças de potencial hídrico, índices espectrais e ecofisiológicas foram mais evidentes nas fases de início (agosto) e de recuperação (dezembro) de deficiência hídrica. Em agosto, cafeeiros em monocultivo apresentaram maior potencial hídrico que cafeeiros consorciados e foram discriminados por apresentarem escores positivos e maiores valores dos índices espectrais NDVI, WBI, ARI1, CRI1, SIPI e FRI. Já em dezembro, maiores valores de potencial hídrico foram encontrados no monocultivo, plantio consorciado com teca em ambos os espaçamentos e acrocarpo no maior espaçamento. Contudo, nessa época, destacou-se cafeeiro consorciado com teca no maior espaçamento, que apresentou escores positivos e valores mais elevados de eficiência do uso da água, eficiência fotoquímica potencial do PSII e índices ARI1, CRI1 e FRI. O consórcio com teca no maior espaçamento apresenta impacto positivo sobre respostas espectrais e ecofisiológicas do cafeeiro, após o período sob deficiência hídrica.
