Conteúdo: | The experiment was carried out on adult 'Valencia; orange (Citrus sinensis Osb.) tree planted in red ferralitic soil at the Estacion Experimental ade Citrios of the Instituto de Ciencias Agricolas in southern Havana Province. A randomized block design was used, with six replications. The treatments were: 160, 320 and 480 Kilograms of nitrogen per hectare and 320 Kilograms of a mixture on nitrogen, phosphorus and potassium per hectare plus a control with no fertilizers fo any kind. The results obtained from 14 years of experiments showed that a regular supply of nitrogen was required for good crops but that it was not necessary to apply more than 160 kilograms per hectare. The response to applications of phosphorus was weak and mainly appearel in the last few years. The applications of potassium did not increase yield, though they did result in heavier fruit in some years. The results of the concentrations of the various elements in the leaves are presented.
