Growth and yield of Coffea arabica L. in Northwest Fluminense: 2nd harvest

Abstract

RESUMO Crescimento e produtividade de Coffea arabica L. na região Noroeste Fluminense: 2º ColheitaNos últimos anos foram lançadas várias cultivares de café recomendadas para diversas regiões. Porém, o conhecimento da resposta dessas variedades em outras regiões tradicionalmente produtoras é desconhecido, o que pode uma vez plantado nestas regiões, comprometer a produtividade dos genótipos devido às diversidades edafoclimáticas, causando prejuízo aos produtores. O presente trabalho tem como objetivo avaliar o crescimento vegetativo e produtivo de genótipos de C. arabica nas condições do Noroeste Fluminense do Estado In recent years, several new coffee cultivars recommended for different regions have been released. However, the performance of these varieties in many traditionally producing regions is unknown. Difference of climate and soil may jeopardize the productivity of the new cultivars and cause losses to farmers. The objective of this study is to evaluate the vegetative growth and productive genotypes of C. arabica in the conditions of the Northwestern Rio de Janeiro State, Brazil. The experiment was settled in 2007, in Panorama 1 Farm, located in the municipality of Varre Sai, RJ. Twenty-five genotypes of C. arabica were planted in a spacing of 2.5 × 0.8 m, using a completely randomized design with five replications and eight plants per plot. There were eight measurements of vegetative growth represented by plant height, stem diameter and number of plagiotropic branches. Assessments of productivity were also performed in years 2009 and 2010. There was a positive phenotypic correlation among vegetative characteristics and between vegetative characteristics and yield in the first harvest, while in the second harvest only the number of plagiotropic branches was positively correlated with yield. Up to date, the genotypes Catucaí amarelo 2 SL, Catiguá MG 02, Acauã,

Growth and Productivity of Irrigated Coffee Trees (Coffea arabica) in Ceres-Goiás

“…The Yellow Catucaí 2SL was the genotype with the best performance for these two characteristics, in the two evaluated epochs is in the group of the most productive genotypes. There is a growth synchrony between these two variables, to support the plant (Rodrigues et al, 2012). The correlation between canopy diameter and yield of coffee benefited per hectare was significant at 1% (0.36), as can be seen in Table 3.…”

“…Comparing the vegetative characteristics with productivity is an important method to study the adaptation of genotypes, observing their performance in a certain region (Rodrigues et al, 2012). The main criterion of selection in coffee is productivity and, for the recommendation of cultivars, it is essential to observe the interaction of the genotype with the environment (Krohling et al, 2017).…”

Agronomic performance of arabica coffee genotypes in northwest Rio de Janeiro State

“…Until the second harvest, positive correlations were observed between vegetative and productivity characteristics (Rodrigues et al, 2012). However, no correlation between productivity and vegetative characteristics were observed for the third harvest, in 2011 (Table 4).…”

Caracteres morfológicos de cafeeiro de porte baixo no primeiro ano de formação em Jaboticabal-SP

“…Em estudo realizado por Rodrigues et al (2012), constatouse correlação positiva entre altura de plantas, diâmetro do colmo, número de ramos plagiotrópicos e produtividade no ano de 2009. Já na safra seguinte foi observado apenas correlação positiva entre o número de ramos plagiotrópicos e a produtividade.…”
