“…Sample locations and methods were described in detail by Faulkner et al (2011a). The ginning machinery sequence was similar for both harvest methods were similar for both harvest treatments and were described by Faulkner et al (2011b). A minimum of 23 kg (50 lb) of lint from each sample was processed into yarn at the Fiber and Biopolymer Research Institute in Lubbock, Texas.…”

“…The recent increases in cotton yields on the High Plains coupled with a change in market demands have raised interest in picker harvesters in the region because picker harvesters are perceived to maintain fiber quality characteristics better than strippers, and may be able to harvest cotton at higher speeds in high yielding stands. Previous research by Faulkner et al (2011b) has demonstrated that picking cotton may result in better fiber quality and lint value than stripping, but the magnitude of those differences are a function of growing conditions and/or fiber maturity. The paper by Faulkner et al (2011b) also summarized other literature comparing the fiber quality of picked and stripped cottons.…”

The effects of harvest methods (cotton picker vs. cotton stripper) on yarn quality from irrigated cotton harvested on the High Plains of Texas with modern equipment was measured using multiple cultivars from six sites over three years. Few differences were detected in carded yarn quality between harvest treatments, while more pronounced differences favoring picked cotton were seen in combed yarns, especially when fibers were immature. During both 2006 and 2007, the evenness of combed yarns was improved by picking over stripping as measured by yarn CV, thick places, and neps (+200%), and the hairiness of carded yarns was reduced by picking. However, evenness differences between harvest methods were not detected in carded yarns. In 2007, cultivar had a greater impact on yarn quality than harvest treatment. This study represents the first commercial-scale harvester comparison project conducted in the High Plains region and the first study to analyze the effects of harvest method on ring-spun yarn quality from a traditional production system.

“…63 of December 5, 2002 from MAPA (BRASIL, 2002), the UI both in the absence (83.59%) and in the presence of scraping plates (84.36%) was also high (Table 3). Faulkner et al (2011) evaluated mechanized harvesting systems with a picker platform and observed UI values of 80.4%, showing that the speed does not influence the intrinsic properties of the cotton fiber quality, in years with ideal growing conditions.…”

There have been increasing demands for high-quality cotton fibers that meet the textile industry quality standards. Concurrently, there have been efforts to reduce contaminants during harvesting to reduce harvesting costs. The goal of this research was to evaluate the efficiency of the picker platform with Variable-Row-Spacing (VRS) for harvesting cotton in narrow rows, over two harvest seasons in two regions within the state of Mato Grosso, Brazil. In this study, how the presence vs. absence of scraping plates and variations in travel speed was related to quantifiable levels of impurities the harvested fibers was examined. The research was divided into three experiments (Exp. I, II, and III), using cotton varieties FM 975 WS, IMA 5672 B2 RF, and IMA 5675 B2 RF, with row spacing of 0.45 m. The experimental design was randomized blocks, in a 2 × 3 factorial design, using the presence/absence of the plate and three speeds (0.61, 1.0, and 1.42 m·s-¹), with seven repetitions, totaling 42 experimental plots. The plot size was 108 m² (3.6 × 30 m). The data were analyzed using the F test in ANOVA and the post-hoc Tukey test (p < 0.05). The results showed that scraping plates increased the number of stems and cones, and reduced the harvest efficiency of cotton planted in narrow rows in the region of Sorriso-MT during the 2013/2014 harvest. For the 2014/2015 harvest, the highest speed and the presence of the scraping plates increased the number of cones in the cotton samples. In the experiment conducted in Serra da Petrovina, the removal of the scraping plates decreased the amount of cones in the harvested cotton. Key words: Cotton planted in narrow rows. Mechanical harvesting. Harvest efficiency. ResumoA demanda por fibras de algodão de alta qualidade para atender a demanda da indústria têxtil e a busca incessante para reduzir a presença de contaminantes no momento da colheita de forma a contribuir para a redução dos custos. O objetivo da pesquisa foi avaliar a eficiência da plataforma Picker VRS (unidades de espaçamento variável) de colheita do algodão adensado no Estado de Mato Grosso, com e sem placas de raspagem, variando a velocidade de deslocamento, quantificando as impurezas nesse processo e avaliando a qualidade extrínseca e intrínseca da fibra colhida. A pesquisa foi dividida em 3 experimentos (Exp. I, II e III). As variedades de algodão utilizadas foram FM 975 WS, IMA 5672 B2 RF e IMA 5675 B2 RF, com espaçamentos entre linhas de 0,45 m. O delineamento experimental utilizado foi de blocos casualizados, em esquema fatorial 2x3, sendo presença e ausência da placa e três velocidades de trabalho (0,61; 1,0 e 1,42m.s-¹), com sete repetições, totalizando 42 parcelas experimentais. A dimensão das parcelas foi de 108m² (3,6 x 30m). Os resultados obtidos foram submetidos à análise de variância por meio do Teste de F, e quando significativos submetidos ao teste de Tukey, a 5 % de probabilidade. As placas de raspagem aumentaram a quantidade de caule, casquinhas e reduziu a eficiência na colheita do algodão adensad...

“…De acordo com a Instrução Normativa n° 63, de 05 de dezembro de 2002, do MAPA (Brasil, 2002), a uniformidade de comprimento foi considerada Alta (83 a 85%) e, segundo a norma ASTM (2012a) D1447, foi considerada elevada (83 a 85%). Faulkner et al (2011) avaliaram os sistemas mecanizados de colheita e observaram diferenças das Unf, de 80,4 (picker) para 79,4 (stripper). Neste experimento, não houve redução da Unf para os sistemas de colheita mecanizados.…”

RESUMO Escolhas no manejo cultural, como a do cultivar e a do sistema de colheita, podem influenciar os índices dos parâmetros de qualidade da fibra do algodão. Objetivou-se, com este trabalho, analisar as características das fibras de dois cultivares de algodão submetidos a diferentes sistemas mecanizados de colheita (picker e stripper). O experimento foi conduzido na safra de 2012, com espaçamento de 0,45 m entre linhas, no município de Juscimeira, MT. Utilizou-se delineamento em blocos casualizados, em esquema de parcelas subdivididas, com dois fatores, sendo eles, A, nas parcelas (dois cultivares) e B, nas subparcelas (três sistemas de colheita - manual, picker e stripper), com cinco repetições. A qualidade da fibra foi determinada em amostras coletadas manualmente da planta e, após a colheita mecanizada, retiradas de dentro do cesto armazenador de cada colhedora. As análises das características das fibras foram realizadas em Laboratório de Classificação de Fibras, com o aparelho HVI (High Volume Instrument). As fibras do algodão colhido com o sistema manual, em seguida, sistema picker apresentam melhores características e melhor qualidade que as das fibras colhidas com stripper.
