Qualidade da fibra do algodoeiro submetido a diferentes lâminas de irrigação e densidades de plantio.

Abstract

A field experiment was carried out in Barbalha, CE, to evaluate the effect of diferent irrigation dephts and planting densities on cotton fibre quality of BRS 200 Marrom cultivar. The experimental design was a split-plot in randomized blocks, disposed in crop strips, with four replications. Four irrigation dephts (450, 550, 650 and 750 mm) and four planting densities (55.500; 111.000; 166.500 and 222.000 plants ha-1) were studied. A furrow irrigation system to applied the amount of water at each irigation event was used. It was observed that irrigation dephts and plant densities had not effect on fibre technological characteristics of tested cultivar.
