Efeito da irrigação com e sem período de déficit hídrico e de doses de adubação sobre produtividade do cafeeiro recepado (Safra 2005).

Abstract

They were appraised the effects of periods of deficit hydric and of fertilizers amounts, through fertigation, about the productivity of the Red Catuaí coffee tree in the crop 2005 that corresponds at 4th crop after the pruned. The experiment was composed by 3 blocks, each block was divided in 5 portions (A = without hydric deficit, B = hydric deficit in June, C = hydric deficit in July, D = hydric deficit in June and July and it E = not irrigated), each portion was divided in 4 subportions (1, 2, 3 and 4 that respectively received 70, 100, 120 and 140% of the fertilizer recommendation). The relative parameters to the productivity were submitted to the variance analysis and to tests of comparison of averages, when necessary. Of analysis variance, it was verified that there was not significant effect of anything of the variation sources on the productivity, wich varied of 56.35 bags ha-1 to 65.92 bags ha-1. One of the factors that might have influenced this behavior, was the good distribution of the pluvial precipitation along the analyzed period.
