英文摘要	In the semi-arid region of Northeastern Brazil, temporal and spatial variations in rainfall are common, resulting in water limitations that significantly impact production, especially of cotton. In this context, chitosan may serve as a strategy to minimize the effects of water deficits by enhancing water and nutrient absorption. This study aimed to evaluate the effectiveness of different concentrations of chitosan as a mitigator of water restriction in the cultivation of the naturally colored fiber cotton variety 'BRS Jade'. The plants were cultivated in drainage lysimeters under greenhouse conditions. A completely randomized design was implemented using a 2 x 4 factorial arrangement, which included two levels of irrigation (100% and 50% of the water requirement of the crop) and four chitosan concentrations (0.0, 0.25, 0.50, and 0.75 g L -1 ), with three replications and one plant per plot. Water restriction at 50% of the required amount reduced the relative water content, the synthesis of photosynthetic pigments, and seed cotton weight. However, foliar application of chitosan at concentrations between 0.25 and 0.50 g L -1 alleviated the detrimental effects of water restriction on the chlorophyll b content; carotenoid content; stem diameter; leaf area; 100 -seed weight; average boll weight; seed cotton weight; total boll dry biomass; and dry biomass of stems, leaves, and shoots of the 'BRS Jade' colored fiber cotton plant.
