Pineapple orange trees were planted in virgin sandy soil and grown for 20 years with different rates of applied superphosphate. In relation to N, the ratios of P3O5 used were 4:0, 4:1, 4:3, and 4:8 Tree growth was not visibly affected by P level. Yields were not appreciably different except for 1 year, 1959, when the trees on the highest rate of P vastly out yielded those on the other treatments. Yields the following 3 years were virtually identical. Fruit quality in the first 10 or 12 crops was not greatly affected by treatment, but thereafter the fruit grown on high P was poorly colored and had lower soluble solids, acids, and vitamin C concentrations than fruit grown without added P. Both leaf and soil analysis indicate that after 20 years without added P,there is little possibility of a critical deficiency developing for many more years. |
