%X Information on nutritional aspects related to phosphorus fertilization is especially important since guava plants are cultivated mainly in tropical regions where P levels are low. The objective of this research was to evaluate the response of young guava plants of cultivar ¡®S¨¦culo XXI¡¯ to phosphorus applied into the soil. The experiment was carried out in 3 dm3 pots filled with samples of a dystrophic Red Latosol (P resin: 8 mg dm-3). Treatments consisted of applying doses of 0, 90, 180, 270, and 360 mg kg-1 of P, and were arranged in a completely randomized design with four replicates. At 175 days after transplanting, P doses applied into soil increase P levels in both soil and plant tissues, resulting in increasing dry mass of guava plants cultivar ¡®S¨¦culo XXI¡¯. The highest development of young guava plants are attained when P is applied from 155 up to 210 mg kg-1 into soil and when P level in leaf tissues occurs from 1.1 up to 1.8 mg kg-1.
