Resumo
To meet the growing demand for cotton production, it is necessary to adopt high-quality seeds. To ensure the production of high-quality seeds, it is essential to consider factors such as the amount of water supplied to the plant and the climate of the region. Therefore, this study aimed to assess the impact of different irrigation blades on the productivity and physiological quality of cotton seeds produced in the Arenito Caiuá region. Cotton seeds from FiberMax FM 911 GLTP cultivar were sown, and, after planting, four water depth treatments were applied: 0 (control, without irrigation), 50, 100 and 150% of crop evapotranspiration (ETc), being maintained until the end of the crop development. The cotton bolls were harvested and delinted manually and the weight of the bolls and seeds was measured. The seeds were subjected to moisture content, germination, and vigor tests. The different irrigation blades applied to the plants affect cotton productivity, with irrigation blades of 50 and 100% ETc providing greater productivity. The absence and excess of irrigation cause a significant reduction in the productivity of cotton and seed. The physiological quality of the formed seeds is not affected by the different irrigation blades applied to the plants.
