Conteúdo: | Cotton has got high demand of both phosphorus (P) and potassium (K) for productivity, and should be cultivated in soils with good availability of these nutrients or that are properly fertilized with them. Soils used in Mozambique for cotton production are poor in P and are used until deprived of their natural fertility. In this work it is reported a study conducted with the objective to calibrate the proper P and K fertilization for cotton in a sandy soil, in Muriaze, Nampula. It was compared the following rates: 0, 70, 140, 210 and 280 kg/ha of P2O5 and 0, 50, 100 and 200 kg/ha of K2O, disposed in a complete factorial 4 x 5 experimental design, with four replications per treatment. Each replication consisted of 5 rows of 5 m each, spaced 0.9 m. All experimental area received 1 ton/ha of calcium dolomite and basic fertilization with 150 kg N/ha, as Urea, halved in an application of 20 kg/ha at the planting and 130 kg/ha 30 days after plant emergency. The cultivar BRS 293 was used for the experiment, being planted in 21/12/2012, with a density of 10 seeds per lineal meter. It was analyzed parameters of plant growth and productivity. There was no response to the K2O rates, as the soil was well served in K. On the other hand, there was a significant linear response to P2O5 increasing rates, both for growth in height as well as productivity, although resulting productivity are quite low (574 to 912 kg of cottonseed/ha), due to severe drought and strong attack of insects plague.
