Advances in the agrotechnical studies of coffee crop (Coffea arabica L.) in Cuba
In Cuba, the agrotechnical studies on coffee crop started within the 60's. They were conducted at the National Institute of Agricultural Sciences. Such studies mainly dealt with all about coffee nursing, plantations at full sunlight and weed control. Their results proved that a coffee nest of three seedlings per bag strengthens them, so that they are able to develop in the nursery at full solar exposure. The possible existence of different overstorey plant species in the nursery was also tested here. The best data were recorded on Gliricidia sepium and Cajanus indicus. After seedling emergence, weeds were allowed to grow for two months to enhance coffee development. Treflan reduces the amount of weeding in the nursery. The best results are achieved at a density of 12,500 plants/ha (2 m x 0.40 m) at full sunlignt. A good crop management was attained by a rotational high pruning (1 m) of four year old plants every three years. The highest yields were recorded by the three year rotational pruning at the density of 5,000 plants/ha. In the field, coffee trees are affected by weeds just within a trimester (February - March - April) of their first year. Chemical weed control through Dalapon at 5 kg/ha + T.C.A. at 10 kg/ha + 2,4-D at 1 l/ha as well as through Diuron at 2,4 kg/ha + Gramoxone at 2 l/ha can kill weeds efficiently by two annual applications, without affecting coffee growth
