Conteúdo: | Cotton has got wide capacity of adaptation to different conditions of clime and soil, allowing reaching profitable productivity if proper crop management is made. In Mozambique, cotton productivity is low, possibly caused by the usage of locally inadequate varieties. In this work it is reported the results of a field experiment conducted to check out the productivity that would be obtained when using an advanced variety, BRS 293, comparatively to a local variety. It was also studied three different dates of planting, spaced every 15 days, starting in 21/12/2012, beginning of the rainy season. The experimental design used was a subdivided plot, in randomized blocks with four replications, with varieties as the plots and the planting dates the subplots. It was measured parameters of plant growth and productivity. Variety BRS 293 showed higher productivity than the local one (1,027 kg of cottonseed compared to 649 kg/ha) when planted at the beginning of the rainy season, with stand of 10-12 plants/m. However, it has shown decreasing productivity in plantings at 15 and 30 days later. Local variety presented a lower stand of plants, with a low capacity of compensating the number of flower bolls per plant, resulting in low productivity, which remained without changes as effect of the date of planting.
