Although most of the Brazilian coffee growing areas are located in regions with enough rainfall, a significant amount is cultivated in regions subjected to water deficit during fall and winter time. This situation reduces coffee yield, since Brazilian coffee cultivars are not adapted to this condition. This work was conducted to evaluate the response to irrigation and aiming to select coffee genotypes that are more adapted to environments subjected to water constrain. The work was carried out in Coromandel, MG, Brazil, a region characterized as marginal to coffee cultivation, due to the shortage of rainfall during fall and winter time. A field experiment was set in January of 2004 using a randomized block designed, with 30 genotypes, six plants per plot and four replications, with and without drip irrigation. During the first 2.5 years all the treatments were irrigated to allow proper plant growth and better homogeneity. Yield (kg/tree) was evaluated in July 2007 and, in average, fruit production was increased in 50% due to irrigation in all the genotypes. The highest response to irrigation was observed in the late maturity genotypes, such as Red Obatã, Yellow Catucaí (late) line 30 cv. 2 and Yellow Bem-te-vi, with 223.3%, 120.9% and 110.9% of yield increase, respectively. On the other hand, the irrigation did not significantly increased fruit production of early maturity genotypes, as observed for Catucaí 785-15, Yellow Catucaí 24/137 (early) cv. 900 and Siriema. Since the early maturity cultivars differentiate flowers in the beginning of the year, when water availability is still not a limiting factor, and the late maturity cultivars flower differentiation occurs later on, during the dry season, it is suggested that the early maturity cultivars are more adapted to those conditions. These data indicates that early maturity genotypes may be an interesting genetic source for the development of coffee cultivars more adapted to regions with low rainfall during fall/winter time.
