“…This can be avoided by using a desiccant before harvesting. Cangussu et al [88] reported the use of the herbicide glyphosate [N-(phosphonomethyl) glycine] as a desiccant at 2.0 L a.i. ha −1 when 90% of the seeds turned brown, without negatively affecting seed germination or vigor.…”

Crambe (Crambe abyssinica Hochst): A Non-Food Oilseed Crop with Great Potential: A Review

et al. 2020

Crambe (Crambe abyssinica Hochst) is an oilseed crop in the Brassicaceae family. Crambe’s ability to survive in diverse environmental conditions, its unique oil composition, the high oil content, suitability for the production of slip agents for plasticizers, the capacity to be easily included in common crop rotations, and its adaptability to equipment used for small grain cultivation has renewed the interest in this emerging crop. Crambe is considered one of the main sources of erucic acid, which can be up to 60% of its seed oil content. Erucic acid (C22:1) is a fatty acid with industrial importance since it is used to produce erucamide, key ingredient in the plastic industry. Inclusion of crambe into crop rotations can be beneficial because of its short life cycle, low fertility requirements, resistance to pest and diseases, and relative drought tolerance. Currently high erucic acid rapeseed (Brassica napus L.) (HEAR) is the principal source for erucic acid. However, the risk of contaminating food quality rapeseed (i.e., canola) by cross-pollination and the negative impact on climate, due to high inputs, are potential limitations to expand HEAR cultivation. Crambe has thus great potential to, at least, partially replace HEAR as a source of erucic acid, if the current knowledge-gap in agronomic management and crop improvement (seed yield and quality) can be addressed. Seed yield needs to be increased to be able to compete with HEAR. In addition, reducing glucosinolates and fiber in crambe meal may increase its inclusion in monogastrics rations. The objective of this review was to compile and summarize new and existing information on agricultural practices in crambe production and management to identify gaps in knowledge and areas for future research to increase the cultivation of crambe.

“…Os herbicidas dessecantes aceleram o processo de perda de água pelas plantas e, consequentemente, das sementes, diminuindo o período de exposição prolongada aos fatores bióticos e abióticos após a maturidade fisiológica (HAMER; HAMER, 2003), aumentando a eficiência da colheita. Nesse sentido, Cangussú et al (2018) observaram que a dessecação das plantas de crambe em précolheita com glyphosate se mostrou eficiente, afetando positivamente a germinação e o vigor das sementes. A aplicação do dessecante nas plantas (2.0 L ha -1 de i.a), com 90% das sementes de coloração marrom, aos 103 dias após a semeadura, possibilita a produção de sementes com desempenho superior.…”

A produção de sementes é um processo que incluem diversas etapas desde o melhoramento, produção, certificação, até a manutenção depois da colheita, cuja finalidade especifica é obter sementes de qualidade, com alta pureza genética, pureza física, qualidade fisiológica e sanitária, que afetam a sua capacidade de originar plantas de alta produtividade. Objetivou-se com esta revisão abordar os principais aspectos práticos verificados durante a produção de sementes de crambe, visando obter sementes de elevada qualidade física, fisiológica, genética e sanitária. A metodologia estudada foi a revisão de literatura com levantando e análise de dados sobre a cultura. Verificou-se que para sementes de crambe ainda não há na literatura informações suficientes quanto às diversas etapas de um sistema de produção de sementes, especialmente no que se refere ao estabelecimento e condução de campos de produção. Diante destas considerações, o conhecimento das condições ideais durante a produção de sementes é de fundamental importância, uma vez que somente aquelas de elevado nível de qualidade proporcionam a maximização da ação dos demais insumos e fatores de produção empregados na lavoura, com respostas na produtividade das culturas.

“…To help combat this loss, chemical desiccation and swathing are common practices in Brassicaceae production to reduce plant moisture following physiological maturity (Kandel & Hanson, 2013; Sanderson, 1976; Sintim et al., 2016). By quickly drying and harvesting the crop using a harvest aid, it may be possible to minimize seed losses associated with decreased plant moisture content (Cangussú et al., 2018; Esfahani et al., 2012). However, the use of shatter‐prone lines like “MN106” in agronomic research has made it difficult to understand the role of harvest aids in pennycress production (Cubins, 2019).…”

Harvest aids did not advance maturity of non‐shatter pennycress

et al. 2023

Reliance on summer annual crops in the Upper Midwest results in fallow land from late fall through early spring, providing opportunities to integrate winter crops, such as pennycress (Thlapsi arvense L.), onto the landscape. Pennycress agronomics have primarily been studied using unimproved wild-type lines prone to seed shatter, resulting in significant yield loss if not harvested early. However, high plant and seed moisture complicates harvest and seed storage. A new breeding line with a reducedshatter mutation made it possible to use harvest aids to reduce plant moisture without the risk of seed loss. The objectives of this study were to quantify the reduction in pennycress seed and biomass moisture after applying a harvest aid and to assess the seed yield, oil content, and crude protein of the reduced-shatter line. This study was conducted over the 2018-2019 and 2019-2020 growing seasons with '"IO217" pennycress in Rosemount, MN. Seed moisture decreased to a similar level by harvest maturity regardless of treatment while swathing was the most effective method of reducing biomass moisture. Natural senescence decreased pennycress moisture content to a harvestable level at the same rate as treated plants, indicating that a harvest aid is not required at this time. Seed yield was two to six times higher than in studies using unimproved pennycress lines. Challenges associated with wild-type pennycress lines, such as uneven germination and late maturation, were prevalent in this study and further genetic improvement will be necessary to ensure successful pennycress production in the Upper Midwest.
