Item Effect of indole-3-acetic acid on growth, physiology and nutritional status of young arabica coffee plants(Universidade Federal de Lavras, 2023-01-20) Erlacher, Wellington Abeldt; Amaral, José Francisco Teixeira do; Amaral, José Augusto Teixeira do; Christo, Bruno Fardim; Ferreira, Daniel Soares; Tatagiba, Sandro Dan; Rocha, Brunno Cesar Pereira; Tomaz, Marcelo Antonio; Rodrigues, Wagner Nunes; Partelli, Fábio LuizCoffee is one of the main agricultural commodities in the world. Thus, research aimed at reducing the productive risks of the crop has been increasingly encouraged, among which the use of plant hormones stands out. In addition, the objective of this work was to analyze the effect of the application of indole-3-acetic acid on the growth, nutrition and gas exchange of young Coffea arabica L plants. The experiment was carried out in the field in the city of Alegre, Espírito Santo, Brazil. The experimental design used was randomized blocks, testing the effect of the application of five doses of indole-3-acetic acid in young Arabica coffee plants, in four replications. The application of indole-3-acetic acid stimulates the growth rate of the stem diameter at a concentration of 60 mg L-1, as well as gas exchange in coffee plants, however it did not favor the increase in the substomatic concentration of CO2 instantaneous and intrinsic efficiency in water use and instantaneous carboxylation efficiency. Although the application of EIA was not able to provide direct gains in coffee growth during the experimental period, a longer evaluation of the treatments would possibly provide promising results for the coffee crop. The multivariate analysis showed that higher doses of auxin have a high relationship with the macronutrients studied.Item Organic coffee growing as a competitive strategy for Mexico in international trade(Universidade Federal de Lavras, 2022-06-09) Anaya, Yadira Zulith Flores; Rodríguez, Deisy Milena Sorzano; Ravina-Ripoll, Rafael; Galván-Vela, EsthelaOrganic coffee growing has positioned itself as a competitive strategic activity in Mexican territory, representing a considerable income alternative for small national producers. However, in recent years despite this context, the country has lost positions, an issue analysed from the use of the method of analysis of ConstantMarket Share (CMS, for its acronym in English), which symbolises a statistical technique that helps to break down the growth of exports, and thus to study their behaviour, which finally allowed to estimate the index to measure the comparative advantages revealed for agricultural products. The results suggest at a general level that there is an increase in the world demand for organic coffee, which has benefited certain countries, together with the concentration of Mexican coffee exports in the markets that have grown most rapidly.Item Decomposition and nutrients released from forest and perennial crops associated with organic coffee(Editora UFLA, 2021) Araujo, João Batista Silva; Silva, Matheus Wandermurem da; Lima, Wallace Luís de; Pereira, Ana Claudia Hertel; Endringer, Denise Coutinho; Souza, Jacimar Luís deAgroforestry consortia increase organic matter and nutrient cycling in agricultural systems. For this reason, the objective of this work was to study the release rate of nutrients and the decomposition of different organic residues, two times of the year, obtained from four cultures intercropped with conilon coffee, aiming to relate the released nutrients to the coffee needs. The decomposition of organic matter residues and the release of nutrients from Inga edulis, Musa spp, Gliricidia sepium, and Bactris gasipaes were evaluated in two different periods. I. edulis residues with a higher amount of polyphenols, and those of Musa spp, with a higher C/N ratio, showed slow decomposition. The decomposition rates were lower in experiments started in March and higher in August. Inga and banana have high residual values of nutrients at 270 days in the decomposition started in March.Item Soil attributes and coffee yield in an agroforestry system(Editora UFLA, 2020) Jácome, Máximo Gerardo Ochoa; Mantovani, José Ricardo; Silva, Adriano Bortolotti da; Rezende, Tiago Teruel; Landgraf, Paulo Roberto CôrreaCoffee growing in an agroforestry system may provide improvements in soil chemical and physical attributes, increase crop yield and diversify production. However, there are few studies on coffee growing intercropped with high quality wood-producing species such as African mahogany, teak and Australian cedar. The objective of this study was to evaluate, in an agroforestry system, the effect of coffee intercropping with tree species and the density of these species on chemical and physical soil attributes and on coffee yield. The experiment was carried out in Santo Antônio do Amparo, MG, and Catuaí Vermelho IAC 99 coffee was used in a 3.4x0.7m spacing. A randomized block design with split plots was used, with one additional treatment and 4 replications. The treatments consisted, in the plot, of three tree forest species: Australian cedar, teak and African mahogany, used intercropped with coffee; and, in the subplots, two densities of these forest species: 82 plants ha-1 (13.6 m between rows and 9 m between plants) and 41 plants ha-1 (13.6 m between rows and 18 m between plants). The additional treatment consisted of conventional coffee cultivation growing without intercropping with the tree species. At 64 months after the experiment was set, when the forest species were still under development, soil samples were taken at a depth of 0 to 0.1 m to determine the following chemical attributes: pH in H2O, potential acidity, organic matter content, P-Mehlich, K+, Ca2+, Mg2+, S, B, Cu, Fe, Mn, Zn and base saturation (V%); and physical soil attributes: bulk density, macroporosity, microporosity, total porosity. Soil temperature at 0.05 m depth and coffee yield were also evaluated. Chemical and physical attributes, besides soil temperature, are similarly influenced with the cultivation of Australian cedar, teak and African mahogany, intercropped with coffee, in both densities, 82 and 41 plants ha-1, after 5 years of implementation of the agroforestry system. Coffee cultivation in agroforestry system with Australian cedar, teak and African mahogany increases the organic matter and P content of the soil, but acidifies the soil and does not influence its physical attributes. The agroforestry system with teak and African mahogany increases coffee yield.Item Evaluation of Conilon coffee productivity intercropped with Ambarella (Spondias dulcis Parkinson)(Editora UFLA, 2020) Sales, Eduardo Ferreira; Baldi, Adriana; Alvez, Juan P.The State of Espirito Santo (Brazil) has 9.4 % of its area cultivated in full sun, monocrop coffee. Coffee has a great importance for the State and a dependence on just one product can make farmers vulnerable to price fluctuations. Integrating coffee (Coffea canephora Pierre ex Froehner) intercropped with Ambarella (Spondias dulcis Parkinson) offers environmental benefits and an extra financial combination through the commercialization of Ambarella fruits. The goal of this study was to verify the effects of the distance and orientation (East-West versus North-South) between Ambarella on coffee crop yield. We assessed two different coffee crops spaced (3 x 1.5) m. Both were intercropped with Ambarella spaced (15 x 7.5) m. The average coffee productivity varied from (2,177 to 7,346) kg plant-1. The lowest productivity was measured in the North-South orientation, during 2016, and the highest in the East-West orientation during 2017. Our findings also indicate that regardless of planting distance, Ambarella did not significantly affected coffee productivity demonstrating that it can be a promising fruit tree to intercrop with Conilon coffee.Item Intercropping period between species of green manures and organically-fertilized coffee plantation(Editora UFLA, 2018-01) Cardoso, Rosileyde Gonçalves Siqueira; Pedrosa, Adriene Woods; Rodrigues, Mateus Cupertino; Santos, Ricardo Henrique Silva; Martinez, Hermínia Emília Prieto; Cecon, Paulo RobertoThe adequate supply of nitrogen to coffee plantation is one of the main challenges of organic agriculture. The aim of the present study was to evaluate the effect of organic fertilization with two legume species in different intercropping periods on nitrogen nutrition, initial growth and productivity of coffee plantation. The experimental design was in randomized blocks, in 2x4 split-plot factorial design, being that the plot consisted of two intercrops (coffee+jack bean and coffee+hyacinth bean) and the four intercropping periods (30, 60, 90 and 120 days after sowing of the legume), and the subplot by 50% and 100% of fertilization for the coffee plantation. The increase in the intercropping period between legumes and coffee plantation favored a greater increase in height and node number of coffee trees, besides showing higher heights when fertilized with 50% of the recommended dose and intercropped with hyacinth bean. The intercropping with the hyacinth bean resulted in a larger crown diameter of coffee trees in 2010 and a larger diameter accumulated in the two evaluated years. Higher N contents were found in coffee trees fertilized with 100% of the recommended dose. The legumes supplied the nutritional requirements of the coffee harvest fertilized with 50% of the dose. The bean yield of the processed coffee is not affected by the intercropping with the green manures of jack bean or hyacinth bean.Item Influência de sistemas de produção de café orgânico arborizado sobre a diversidade da fauna invertebrada epigéica(Editora UFLA, 2015-07) Guimarães, Nathalia de França; Gallo, Anderson de Souza; Souza, Maicon Douglas Bispo de; Agostinho, Patricia Rochefeler; Gomes, Michele da Silva; Silva, Rogério Ferreira daObjetivou-se, no trabalho, avaliar a influência de sistemas de produção de café orgânico arborizado sobre a diversidade da fauna invertebrada epigéica. O estudo foi conduzido num Argissolo Vermelho, de textura arenosa. O delineamento adotado foi o de blocos casualizados, em parcelas subdivididas, com cinco repetições. As parcelas principais foram os sistemas de manejo: café orgânico (CO), café orgânico consorciado com quatro espécies vegetais (CO4), café orgânico consorciado com nove espécies vegetais (CO9), café orgânico consorciado com cinco espécies vegetais (CO5), café orgânico consorciado com banana (CB) e em área de vegetação nativa (VN). As subparcelas foram as épocas de avaliação (outubro/2012 e julho/2013). Em cada sistema foram instaladas cinco armadilhas de queda “pitfall” para captura da fauna invertebrada epigéica. Além disso, foi avaliada a quantidade de serapilheira (t ha -1 ), próxima às armadilhas. Em todos os sistemas, houve grande dominância de Collembola. A densidade e a riqueza de macroinvertebrados epígeos foram influenciadas pelos sistemas de manejo do solo e pelas épocas de amostragem.Item Microclima e crescimento vegetativo do café conilon consorciado com bananeiras(Editora UFLA, 2015-04) Araújo, André Vasconcelos; Partelli, Fábio Luiz; Oliveira, Marcos Goes; Pezzopane, José Ricardo Macedo; Falqueto, Antelmo Ralph; Cavatte, Paulo César;O consórcio de café Conilon (Coffea canephora) com bananeira (Musa sp.), vem sendo muito utilizado entre os agricultores. Objetivou-se caracterizar o microclima existente num sistema de consórcio de café Conilon com bananeira e seus efeitos no crescimento do cafeeiro. O café foi plantado com espaçamento de 3,5 x 1,2 m, consorciado com banana subgrupo Terra, com espaçamento 10,5 x 1,5 m, plantados no sentido Leste-Oeste. Utilizou-se um delineamento inteiramente casualizado, com três tratamentos e quatro repetições, sendo os tratamentos divididos de acordo com a distância entre as bananeiras e a lavoura cafeeira. As avaliações climáticas incluíram a irradiância, temperatura e umidade relativa do ar, em fevereiro (verão) e junho (inverno). Em relação ao cafeeiro, avaliaram-se a concentração de nutrientes foliares, o comprimento dos internódios dos ramos plagiotrópicos e ortotrópicos, área foliar e estimação do teor de clorofilas (a e b e total) dos cafeeiros, no verão e no inverno. A bananeira diminuiu a incidência de radiação e temperatura, ao longo do dia, nos cafeeiros, especialmente naqueles situados mais próximos às bananeiras e, em particular, no período de verão. O sombreamento promovido pela bananeira não foi suficiente para promover alterações morfológicas no cafeeiro. Contudo, os teores foliares de P, K, Ca, Mg, S, B, diminuíram principalmente nas plantas situadas a 1,75 m da bananeira. Os valores de clorofila b e total, foram maiores nos cafeeiros situados próximos às bananeiras, no período de inverno.Item Consorciação em cafeeiros orgânicos por diferentes períodos com feijão-de-porco ou lablabe(Editora UFLA, 2014-10) Moreira, Guilherme Musse; Barrella, Tatiana Pires; Martins Neto, Fábio Lúcio; Martinez, Herminia Emilia Prieto; Santos, Ricardo Henrique SilvaObjetivou-se, neste trabalho, avaliar o efeito de períodos de consorciação com lablabe ou feijão-de-porco sobre o crescimento e produtividade de cafeeiros. Os tratamentos corresponderam à combinação fatorial entre leguminosas e períodos de consorciação (30, 60, 90 e 120 dias após plantio) mais uma testemunha. O experimento foi conduzido durante dois anos em Rio Pomba, Minas Gerais, Brasil. Foram avaliadas a produção de massa das leguminosas, o crescimento e produção dos cafeeiros. Houve acúmulo linear de massa das leguminosas em função do tempo de consorciação. No primeiro ano, o feijão- de-porco (2,65 t ha -1 ) acumulou mais massa que a lablabe (1,89 t ha -1 ). No segundo ano, a lablabe acumulou 5,74 t ha -1 e o feijão-de-porco 2,89 t ha -1 , aos 120 dias. No primeiro ano, o aumento do período de consorciação com a lablabe resultou em redução do diâmetro de copa e do número de folhas por ramo dos cafeeiros. Já no segundo ano, o cafeeiro cresceu mais quando consorciado com a lablabe do que com feijão-de-porco. Comparativamente à testemunha, as leguminosas reduzem a produtividade dos cafeeiros com a consorciação, apresentando contudo efeitos diferentes em função da espécie e período de consorciação.Item Fauna edáfica em sistemas arborizados de café Conilon em solo de tabuleiros costeiros(Editora UFLA, 2014-07) Teixeira, Alex Fabian Rabelo; Silva, Victor Maurício da; Mendonça, Eduardo de SáO Espírito Santo é o maior produtor brasileiro de café conilon, destacando-se a predominância de monocultivos na região norte do Estado. Alguns agricultores consorciam cafeeiros com espécies arbóreas, modificando as condições edafoclimáticas dos agroecossistemas. Porém, estudos sobre o efeito dessa prática, em relação à fauna do solo são incipientes. Objetivou-se, neste trabalho, estudar o efeito da arborização em cafezais de conilon sobre a meso e macrofauna edáfica no norte do estado do Espírito Santo. No período chuvoso e seco, a fauna foi amostrada com o uso de armadilhas do tipo pitfall, instaladas em três agroecossistemas de cafeeiros: monocultivo; consorciado com cedro australiano (Toona ciliata M. Roemer); e consorciado com teca (Tectona grandis L. f.). Em seguida, os organismos foram identificados em grandes grupos taxonômicos. Foi coletado um total de 10.451 invertebrados na superfície do solo, pertencentes a 20 grupos taxonômicos, a maioria no período chuvoso. Independentemente do período e sistema avaliado, Collembola e Formicidae foram os grupos predominantes na superfície do solo. A riqueza de grupos taxonômicos foi maior no período seco em todos os agroecossistemas. No período chuvoso, a diversidade (H’) e equitabilidade (J’) foram maiores (p<0,10) no consórcio com cedro comparado aos demais sistemas, com valores de 0,45 e 0,68, respectivamente. A arborização de lavoura de café com cedro australiano proporciona maior oferta de recursos (energéticos e habitat, por exemplo) para a fauna do solo, sendo menos vulnerável às alterações climáticas sazonais.
