(Editora UFLA, 2020)The objective was to evaluate the chemical attributes in a coffee growing area, according to different agronomic techniques used and their associations. The experiment was conducted in the field, from January 2016 to October ... -
(Sociedade Brasileira de Ciência do Solo, 2021-11-22)Molybdenum (Mo) availability is strongly affected by soil pH, which determines the dynamics of electrical charges and the adsorption of molybdate. This study evaluated the effects of nitrogen (N) and Mo application on the ...
-
(Universidade Federal de Santa Maria, 2022)This research evaluated the effects of coffee cultivation with two different water regimes associated or not with liming and the presence/absence of brachiaria as intercrop on the activities of the soil enzymes β-glucosidase, ...
-
(Editora UFLA, 2014-01)At present the need for water and nutrients in agriculture is increasing, and this can become a problem because the high cost of fertilizers and low supply of water resources, requiring alternative sources of water and ...
-
(Universidad Nacional de Colombia, 2018)Coffee cultivation depends on water supplied by rain or irrigation, which, in turn, affect productivity and harvest distribution. Knowing the influence of plant spacing on the behavior of soil moisture and water consumption, ...
-
(Instituto de Florestas da Universidade Federal Rural do Rio de Janeiro, 2019)The objective of this study was to evaluate the occurrence of the soil macrofauna in coffee production systems, as well as their relationship with edaphic properties. Therefore, two coffee production systems were selected: ...
-
(Instituto Virtual da Biodiversidade | BIOTA – FAPESP, 2018)Brazil has always been one of the most important coffee producing countries. Lately, there has equally been a renewed interest in alternative coffee production systems. The state of Espírito Santo is the second greatest ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2021)Land use and tillage practices may change soil structure and undermine sustainable agriculture; however, such changes are hardly identified in the short term. In this sense, agroforestry systems have been used to reduce ...
-
(Sociedade Brasileira de Ciência do Solo, 2011-03)Research data have demonstrated that the P demand of coffee (Coffea arabica L.) is similar to that of short-cycle crops. In this context, the objective of this study was to evaluate the influence of annual P fertilization ...
-
(Empresa Brasileira de Pesquisa Agropecuária - Embrapa, 2017-07)The objective of this work was to evaluate the cultivation effects of organic conilon coffee (Coffea canephora) intercropped with tree and fruit species on soil physico-hydraulic properties. Conilon coffee managements in ...
-
(Universidade Federal de Viçosa, 2011-11)Coffee cultivation via central-pivot fertigation can lead to fertilizer losses by soil profile internal drainage when water application is excessive and soils have low water retention and cation adsorption capacities. This ...
-
(Departamento de Engenharia Agrícola - UFCG, 2020)The form of occupation of the state of Rondônia, Brazil, favored the extensive agriculture, which resulted in a fast deforestation. The removal of forests and inadequate soil management and use, combined with a hot and wet ...
-
(Departamento de Engenharia Agrícola - UFCG, 2009-05)Basic information for a rational soil-water management of the coffee crop is still insufficient, particularly under irrigated conditions. Of great importance for the estimation of water requirements of coffee crops are ...
-
(Associação Brasileira de Engenharia Agrícola, 2013-03)Irrigation management can be established, considering the soil water potential, as the limiting factor for plant growth, assuming the soil water content between the field capacity and the permanent wilting point as ...
-
(Sociedade Brasileira de Química, 2005)This paper describes a Solid Phase Microextraction method (SPME-CG) to the determination of organophosphorus pesticides in samples of fresh-water fish, water, potatoes, guava and coffee by capillary gas chromatography with ...
-
(Sociedade Brasileira de Química, 2015)Solubility and bioaccessibility of Ba, Ca, Cr, Cu, Fe, Mg, Mn, P, Sr and Zn in slim coffees were investigated using an in vitro method. Two different compositions of solutions simulating gastric and intestinal juices were ...
-
(Editora UFLA, 2015-11)Brazil imports most of the potassium that it consumes in agriculture, however, such huge external dependence can be minimized with the use of alternative local K bearing rocks. This experiment was conducted with the objective ...
-
(Universidade Federal de Santa Maria, 2009-03)O objetivo neste trabalho foi avaliar a influência do sombreamento, durante o período de desenvolvimento de gemas florais, sobre o desenvolvimento e maturação dos frutos, produção e tamanho dos grãos de Coffea arabica L. ...
-
(Universidade de São Paulo, Escola Superior de Agricultura, 1967-02-15)This paper deals with data obtained in 1963, 1964, 1965 e 1966 in shaded and unshaded coffee plots at Piracicaba, São Paulo, Brazil. The results can be summarized as follows: a. the production, in shaded and unshaded plots, ...
-
(Universidade de São Paulo, Escola Superior de Agricultura, 1971-10-18)Os dados obtidos durante os anos de 1967 a 1971 (2 biênios: 1967/1968 e 1670/1971) no cafèzal da E.S.A. "Luiz de Queiroz", parte sombreada e parte a pleno sol, foram estudados no presente trabalho, complementando aqueles ...
