Cotton fiber quality affected by water availability and silicon application

The quality of cotton fiber is a fundamental criterion for determining the commercial value product, being influenced by conditions cultivation. study aimed to evaluate irrigated and non-irrigated cultivation systems management silicon fertilization on characteristics. experiment was carried out in field Selvíria-MS, 2017/2018 agricultural crop. It adopted randomized block design, 2x6 factorial scheme, with two cultivationconditions (irrigated rainfed) six doses Si (0, 50, 100, 150, 200 400 g ha-1), four replications. Seeds genotype TMG 11 WS were used. Irrigation sprinklers spaced at 6x6 m. application via leaf 50 70 days after emergence. From thecotton fiber, characteristics length, micronaire, strength, uniformity, elongation, reflectance, yellowing, degree leaves, impurity particles analyzed. data submitted analysis variance F test, means compared condition, regression amount Si. showed improvement resistance, reflectance yellowing.The reduced grade fibers.
