Ricci, Marta dos Santos Freire; Cocheto Junior, David Goronci; de Almeida, Fernanda Fátima DelgadoAiming to evaluate the modification occurred in microweather condition, phenology and external morphology of coffee trees in shaded and full sun systems, the present study took place in an area of the Agroecological Production Integrated System (Sistema Integrado de Produção Agroecológica), in Seropédica, RJ. Three Conilon (Coffea canephora) coffee cropping systems were evaluated, in which two of them the coffe...

Ricci, Marta dos Santos Freire; Costa, Janaina Ribeiro; Viana, Abraão José Silva; Risso, Ilzo Artur MoreiraTo evaluate biomass production and nutrient accumulation by the spontaneous vegetation in organic coffee crops and the phytosociology of these species, an experiment was set up at Fazendinha Agroecológica, in Seropédica, Rio de Janeiro state, in Brazil. The experiment consisted of three treatments, corresponding to systems of cultivation of conilon coffee (Coffea canephora Pierre ex A. Froehner) i...
Effect of gliricídia (Gliricidia sepium) in nitrogen nutrition on coffee plants...
Coelho, Renato Alves; Silva, Gabriela Tavares Arantes; Ricci, Marta dos Santos Freire; Resende, Alexander Silva deCoffee is a crop with high economical importance to Brazil. It is cultivated on about 2,4 millions hectares spread in almost all the country. Nitrogen fertilizers are routinely used by coffee growers and alternatives to reduce their applications are important. In this study, coffee plants (Coffea canephora Pierre ex Froehn) intercroped with gliricídia (Gliricidia sepium (Jacq.) Steud.) and banana (Musa p...
Soil biological attributes in organic coffee farming, pastures and forests in M...
Pimentel, Márcio Sampaio; Aquino, Adriana Maria de; Correia, Maria Elizabeth Fernandes; Costa, Janaina Ribeiro; Ricci, Marta dos Santos FreireSoil microbiological attributes and edaphic macrofauna were evaluated with sampling in four seasons of one-year study on six contrasting environments: two coffee cultivars (Coffea arabica L.) with and without crotalaria (Crotalaria spectabilis Roth.) intercroping; pasture and forest. Soil samples were taken in May, August and November, 2002 and February 2003 to evaluate the microbial biomass, basal respiration,...
