Effect of different types of harvest on the technological quality of cotton fiber in high-density crops
Cotton fiber characteristics are influenced by the genetic and environmental factors, such as management, climate maturation, and significantly by harvesting conditions. The objective of this study was to analyze the variables of cotton fiber characteristics depending on the, picker, and stripper harvest systems, in narrow row cotton system. The experiments are conducted for five seasons in Argentina. The two first season in watering crop a de the tree last at rainfall. The cotton samples, taken from the stored basket of harvesters, were derived by mechanical systems harvesting. The analysis of the frequency distribution of the most significant parameters that determine the quality of the cotton fiber allowed to detect minimum changes in the distributions and these did not modify the class interval more frequently, which would not imply changes in the technological quality of the fiber harvested with different systems of harvesting stripper in relation to the picker. The changes in the distribution were greater when the test was carried out in rainfed conditions due to a lower control of the fruiting of the crop, which makes the management of the crop relevant in systems that were harvested with stripper systems
Keywords: harvesting systems, fiber length, fiber quality, Gossypium hirsutum, frequency distribution.
