EFFECT OF LIIMING AND PHOSPHOR DOSES ON RADISH CROP IN SAND SOIL/EFEITO DA CALAGEM E DOSES DE FÓSFORO NA CULTURA DO RABANETE EM SOLO ARENOSO

Radish represents a great cultivation alternative for family farmers. The objective of this study was to study the nutritional relationships between phosphorus and limestone, including possible interactions between them. The experiment was carried out in a greenhouse of the Federal University of Goias, cultivating radish (Raphanus sativus L.), variety Crimson Gigante, in pots with 3 kg of sandy soil. A completely randomized design in a 2x5 factorial scheme was used, with two doses of limestone, equivalent to 0 and 3.5 t ha-1, dose necessary to increase base saturation to 80% and five phosphorus doses (P). : 0, 50, 100, 200 and 400 mg kg-1, with three repetitions per treatment. Dry mass was evaluated in relation to phosphorus doses and the nutritional relationship between soil and leaf. There is a nutritional relationship between phosphorus and limestone. The use of liming and phosphate fertilization is recommended for radish production, with a dose of 200 mg phosphorus per kilogram of sandy soil.
