Item Sombreamento dos cafèzais II: resultados do 4.° biênio (1959/1960)(Universidade de São Paulo, Escola Superior de Agricultura, 1961-03-04) Godoy Junior, C.; Graner, E. A.This paper deals with data obtained in 1959 and 1960 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, did not show differences statisticaly significant; b) the percentage of coffee berry borer infestation was higher in shaded plots as compared with unshaded ones; c) the percentage of green, ripened and dry fruits depends of the year and of the harvest time. In the same harvest time, both for shaded and for unshaded plots the percentages in the shaded plots were higher for green fruits and lesser for ripened and dry fruits; d) coffee fruits brought from the field in the harvest time yielding up in unshaded plots as compared with shaded ones; e) the relation grains/dry fruits was better in shaded plots.Item Sombreamento dos cafèzais I.: resultados de três ciclos bienais (1953/1958) obtidos na escola "Luiz de Queiroz"(Universidade de São Paulo, Escola Superior de Agricultura, 1959) Graner, E. A.; Godoy Junior, C.The present paper discusses the data obtained in shade and unshaded coffee plots at Piracicaba, São Paulo, Brazil. The results, analysed statistically, can be summarized as follows: a) unshaded plots produced 17% more than shaded ones; b) the percentage of coffee berry borer infestation was higher in shaded plots as compared with unshaded ones; c) the percentage of green (not ripened fruits) depends of the harvest time. When the harvest was retarded, the percentage of green fruits was higher in the shaded plots. When the percentage of green fruits was the same, both in shaded and unshaded plots, the percentage of ripened was higher and the percentage of dried fruits was lesser in the shaded plots as compared with unshaded ones; d) other comparisons as production of dried grains by the field fruits, relation between dried fruits and dried grains and cup-test by expert coffee-taster, did not show differences among shaded and unshaded plots.
