“…O planejamento da semeadura do algodão deve ser realizo para que a colheita seja feita em uma época favorável com poucas precipitações (junho e julho), para que não afete o preço da pluma, que segundo Kazama et al (2016), a colheita é uma etapa de alto custo e de extrema importância no processo produtivo do algodão, uma vez que, se mal conduzida, acarretará prejuízos de qualidade e de quantidade ao produto final.…”

Resumo Os elementos climáticos como temperatura do ar e precipitação exercem influência direta sobre as culturas agrícolas, principalmente no algodoeiro, determinando e influenciando sua adaptação a diferentes regiões. O objetivo deste trabalho foi determinar a adaptabilidade agroclimática e a probabilidade de chuvas para a cultura do algodão para os municípios de Rondonópolis, Tangará da Serra e Campo Novo do Parecis, estado de Mato Grosso. Utilizaram-se dados diários históricos de precipitação e temperatura do ar, disponibilizados pelo Instituto Nacional de Meteorologia (INMET). Com base nas exigências climáticas da cultura do algodoeiro foi classificada a adaptabilidade nas regiões durante o ano em período decendial. Foi calculada a probabilidade empírica e a classificação dos riscos de ocorrerem chuvas menores ou iguais a ETc durante o ciclo da cultura. A temperatura do ar média registrada nos municípios esteve entre a faixa indicada para a cultura (≥ 18 a ≤ 30 °C). Os municípios estudados podem ser considerados aptos ao cultivo do algodão no período safrinha (semeadura realizada de dezembro a fevereiro), considerando a temperatura e precipitação pluviométrica média local. Os riscos de ocorrerem precipitações menores ou iguais a ETc do algodoeiro, variaram de acordo com o estádio fenológico da cultura.

“…These factors include environmental growth conditions, extraction methods, harvesting timing, and harvesting methods [142]. Plant age, harvesting method, and fiber extraction method are crucial in determining fiber quality and, consequently, the quality of composites produced with these fibers.…”

The Amazon rainforest, spanning multiple countries in South America, is the world’s largest equatorial expanse, housing a vast array of relatively unknown plant and animal species. Encompassing the planet’s greatest flora, the Amazon offers a tremendous variety of plants from which natural lignocellulosic fibers (NLFs) can be extracted. In this century, NLFs, which have long been utilized by indigenous populations of the Amazon, have garnered interest as potential reinforcements for composites, whether polymer- or cement-based, in various technical applications such as packaging, construction, automotive products, and ballistic armor. A comparison with synthetic materials like glass, carbon, and aramid fibers, as well as other established NLFs, highlights the cost and specific property advantages of Amazon natural fibers (ANFs). Notably, the sustainable cultivation and extraction of ANFs, as alternatives to deforestation and livestock pasture, contribute to the preservation of the Amazon rainforest. This review article provides a comprehensive examination of recent studies directly related to ANF-reinforced polymer matrix composites. The specific advantages, proposed applications, and reported challenges are highlighted, shedding light on the potential of these unique natural fibers.

“…The planting system adopted in the farms is SPD, possibly inserted in the area volume cited by Peixoto et al (2019), whose understanding is anchored in the molds proposed by Phillips et al (1980), presenting the gains gauged by Salton, Hernani and Fontes (1998). Cotton planting in the research region is done in the conventional system (Clawson et al, 2008) to the detriment of the adensed system as discussed in Rosolem et al (2012) and Kazama et al (2016). According to the APPA executive, "our region is very humid, so if it is adensed, it is much more prone to diseases.…”

“…The technology of reducing the spacing between the rows of cotton -adensed method (Narrow Row cotton -NRC), is a technique of North American origin that allows reducing the crop cycle (Rosolem et al, 2012;Kazama et al, 2016), allowing the minimization of phytosanitary applications, with consequent reduction of production cost, being, in many cases more advantageous in relation to the conventional cropping system (Conventional Row)spacing between 0.76 to 102 cm (Constable, 1977;Clawson et al, 2008). Empirical studies have demonstrated the reduction in costs resulting from the adoption of the adensed planting system in comparison with the conventional system (Jost & Cothren, 2001), above all because of the lower use of phytosanitary products.…”

The study aims to study the operations of the cotton chain at Agro-industrial Cooperative Holambra II, especially the operations of planting, harvesting, processing and storage and destination of byproducts. Of a basic nature, with a qualitative focus and exploratory descriptive objectives, the Case Study approach was used, supported by bibliographic research. Semi-structured interviews, documentary research and structured observation were the tools used in data collection. The Cooperative implemented changes in its organizational and compliance structure, seeking to increase its efficiency in decision-making, in addition to expanding its competitive advantages with better market positioning. The 2020/21 crop showed a sharp reduction in planted area, in view of the uncertainties caused by the Covid-19 pandemic, in addition to competition from other products, with a consequent drop in production, and productivity above the average of the last five harvests. The Cooperative's strategy for anticipating the harvest period provides conditions for making the product available on the market in advance, with the possibility of obtaining higher prices. In the 2019/20 harvest, the production of plume at the Cooperative was equivalent to more than 70% of the state production. The study contributes to the expansion of the study of agricultural cooperatives in the field of management, focusing on the production of cotton, which produces the most important of textile fibers.Probably, the COVID-19 pandemic will cause a significant contraction in world trade in 2020. Preliminary indicators already point to sharp falls in the first and part of the second half of 2020. For the first time since the 2008-2009 crisis, the volume of world trade in goods has plummeted in the first half of 2020, under pressure from rising trade tensions, especially between the United States and China, and weakening economic growth, particularly due to COVID-19.Andressa Vieira da Cruz et al.
