Conteúdo: | Cotton needs soils with good amounts of available phosphorus (P) or annual fertilization to correct its needs of extracting 25kg of P per ha to produce a ton of cottonseed. Phosphorus fertilizer is expensive and should be used with maximum efficiency. Soils from Mozambique are poor in P, and fertilizer is rare in the local market, due to poor demand and high cost. Thus, a study was conducted to check out the effect of application of P and the best way of disposing P fertilizer in the soil. Two rates of P2O5 (0 and 80 kg/ha) were compared, with four methods of application: no application; broadcasting over the soil; broadcasting and incorporation into the soil; and incorporation in the planting row. Every treatment was replicated four times, being each one 5 rows of 5 m each, spaced 0.9 m. Before planting, all experimental area received liming (1 ton/ha of calcium dolomite) and basic fertilization with 150 kg N/ha and 100 kg K2O/ha. The cultivar BRS 293 was used for the experiment, being planted in 21/12/2012, with a density of 10 seeds per lineal meter. Cotton grew better in the presence of P, but there was not response in its productivity, because of loss of cotton flower buds and small bolls due to strong insect attacks and severe drought during the growth period.
