The management of phosphate fertilizer efficient cerrado soils is essential pair increased productivity, cost reduction and viability of existing production systems. Thus, the present work was to evaluate the effect of fertilizer doses phosphate BASIDUO® In Production Indicators and calibration of phosphorus fertilization for cotton cultivation. The test was conducted using a randomized block design with five replicates and three replicates in each repetition. The five treatments consisted of application of phosphate fertilizer BASIDUO® at rates of 0 ; 357.14 ; 714.29 ; 1071.43 and 1428.57 kg ha- 1 which corresponds to 0 ; 100; 200; 300 and 400 kg ha- 1 of P2O5. The variables evaluated were: plant height, number of branches per plant, the first branches height, stem diameter, number of branches per plant, number of bolls per plant, boll mass, mass of 20 boll seed mass 100 seeds and cotton boll fibers 20, 20 bolls and mass productivity. The phosphorus fertilization using BASIDUO® fertilizers significantly influenced most of the traits evaluated, with greater emphasis on increasing productivity in 16 @ ha- 1 more than in the control plants.
