“…Despite the effect of compaction, the crambe grain yield (1.4 to 2.5 Mg ha -1 ) was within the expectations for southern Brazil (Cattanêo et al, 2016;Marins et al, 2018). When the compaction degree was greater than or equal to 53%, we observed a reduction in the grain yield of the crambe.…”

Crambe is a new crop that produces oil used for biodiesel production. Soil compaction in a no-tillage (NT) system is one of the main challenges for sustainable grain production in soil clay. The objective of this study was to evaluate the effect of compaction degree on crambe grain yield over two years. The levels of artificial compaction were generated using a roller compactor (0, 1, 3, and 5 passes) under a NT system. The experimental design was a strip block, and soil density and crambe grain yield were evaluated. The passes of the roller increased the density from 0.98 to 1.24 Mg m−3 in the 0–0.1 m layer, and 1.03 to 1.15 Mg m−3 in the 0.1–0.2 m layer. As a result, the compaction degree increased from 53% to 66% in the 0–0.1 m layer and 54% to 61% in the 0.1–0.2 m layer. Five passes of the roller compactor reduced the crambe grain yield by 41% and 9% in the first and second years, respectively, compared to the NT system without additional compaction. The crambe grain yield was reduced when the compaction degree reached 53%; therefore, crambe is not suitable for compacted soils.

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.

“…Fries) is a type of Brassica oilseed, which are the main sources of vegetable oil in semi-arid regions (Premi et al, 2013). As there is a need for plants with industrial potential, this species may be an alternative for cultivation in tropical regions, since it can be grown in rotation in idle areas with autumn-winter crops (Cattanêo et al, 2016). However, in no-tillage systems, owing to the residues left by antecedent species and subsequent utilization, it is necessary to investigate how crambe behaves under crop rotation.…”

Crambe (Crambe abyssinica Hochst. ex R.E. Fries) is an oilseed crop that can be cultivated in tropical conditions and used for the production of industrial oil. While crambe is believed to be a suitable crop for no-tillage systems, identification of appropriate crop species to precede it is necessary to improve its grain yield and oil content. In this study, we aimed to assess the short-term effects of crop rotation on the grain yield and oil content of a crambe crop cultivated after spring-summer cover crops. The experiment was conducted on an Rhodic Hapludox soil in Santa Helena-PR, Brazil. The experimental design consisted of randomized blocks with four replications. The plots consisted of pearl millet (Pennisetum glaucum), grass brachiaria (Brachiaria brizantha), sorghum (Sorghum bicolor), sunn hemp (Crotalaria juncea) and a fallow area (spontaneous vegetation). Grain yield, oil content, and oil yield were measured. Crambe oil content was influenced by the cover crops. The use of crotalaria as predecessor species resulted in higher oil content, but the result did not differ from that observed in the fallow area. However, grain yield and oil content were benefited by the crotalaria cover crop in the short-term. Crambe looks promising as an alternative oilseed crop for South Brazil when seeded in autumn with crotalaria cover crop in Rhodic Hapludox.

Crambe affected by biological and chemical seed treatments

Abstract: Crambe has great potential for cultivation in tropical regions, but its biotic factors may be a limiting aspect for its production. Thus, we aimed in this study to assess the effect of pre-sowing seed treatments on seedling emergence, root system, production components, and oil.
