Conteúdo: | Cotton extracts around 69 kg of nitrogen (N) to produce a ton of cottonseed, thus depriving the soil with this nutrient in a few campaigns if it is not replenished by mineral or organic reposition. Soils poor in organic matter are used to cultivate cotton in Mozambique, and there is no fertilizer recommendation established for the area, resulting in low productivity. In this work is reported a study whose objective was to calibrate N fertilizer rates to recommend for this crop. The study was carried out in Muriaze, Province of Nampula, with treatments being the following rates of N: 50, 100, 150 and 200 kg/ha, in a complete randomized block design Every treatment was replicated four times, being each one 5 rows of 5 m each, spaced 0.9 m. All area received a basal fertilization with P2O5 equivalent to 120 kg/ha, as Triple Superphosphate, and K2O equivalent to 120 kg/ha, as Potassium Chloride. It was also limed with one ton/ha of calcium dolomite. 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 evaluated parameters of growth and production. There was a severe hydric stress during growth and flowering of cotton, added to a strong attack of caterpillars into the flower buds. So, despite of the N fertilization to increase the number of apples/plant, there was not increase in plant growth and productivity. It is recommended that the experiment be replicated in time and in more than one place in the next campaign.
