“…Acceptance of Crambe meal by the feeds Industry is based on its attractive price and satisfactory performance as a feed for ruminant animals [10]. Crambe was also cultivated in China [11]. Since 1970s, traditional breeding by successive selection within C. abyssinica has been carried out in many countries and several cultivars have been released such as "Prophet", "Indy", "Meyer" [12], "BelAnn" and "BelEnzian" [13] by mass selection.…”

In the present study correlation, regression and path analyses were carried out to decide correlations among the agronomic traits and their contributions to seed yield per plant in Crambe abyssinica. Partial correlation analysis indicated that plant height (X 1 ) was significantly correlated with branching height and the number of first branches (P < 0.01); Branching height (X 2 ) was significantly correlated with pod number of primary inflorescence (P < 0.01) and number of secondary branches (P < 0.05) and negatively correlated with number of first branches (P < 0.01); Number of first branches (X 3 ) was significantly correlated with number of secondary branches (P < 0.01), pod number per plant and 1000-grain weight (P < 0.05); Number of secondary branches (X 4 ) was significantly correlated with seed yield per plant (P < 0.05); Pod number per plant (X 7 ) was significantly correlated with seed yield per plant (P < 0.01) and negatively correlated with 1000-grain weight (P < 0.01); 1000-grain weight (X 8 ) was significantly correlated with seed yield per plant (P < 0.01). Stepwise regression and path analyses indicated that only pod number per plant and 1000-grain weight contributed significantly to seed yield per plant at P < 0.01 and P < 0.05, respectively. The regression formula for contributions of pod number per plant (X 7 ) and 1000-grain weight (X 8 ) to seed yield per plant (Y) is Y = 0.006 X 7 + 1.222 X 8 − 7.191. The path coefficient of pod number per plant to seed yield per plant was 0.967 and that of 1000-grain weight was 0.194. The determination coefficient of pod number per plant and 1000-grain weight to seed yield per plant was 0.983 and the determination coefficient of other agronomic traits was 0.130. Coefficient of variance indicated that the length of primary inflorescence showed the greatest variation, followed by seed yield per plant, pod number per plant, number of secondary branches, branching height, pod number of primary inflorescence, number of first branches, seed yield per plot, 1000-grain weight and plant height. It was suggested that seed yield per plant in Crambe might be improved by increasing the pod number per plant through selection or cultivation, but the negative correlation between pod number per plant and 1000-grain weight also needs to be considered.

“…Nesse sentido, há uma busca por novas oleaginosas que produzam óleos não comestíveis, para a produção de biodiesel dentro das normas internacionais de qualidade. Culturas pouco conhecidas no Brasil, como o crambe (Crambe abyssinica) e o pinhão-manso (Jatropha curcas), ou conhecidas mas não trabalhadas para a produção de óleo, como o nabo-forrageiro (Raphanus sativus), despontam como alternativas interessantes para a produção de biodiesel (Wang et al, 2000;Roscoe et al, 2007).…”

Resumo -O objetivo deste trabalho foi realizar caracterização química de sementes e de tortas de pinhão-manso (Jatropha curcas), nabo-forrageiro (Raphanus sativus) e crambe (Crambe abyssinica) após a extração do óleo por prensagem mecânica. Sementes inteiras dessas espécies foram submetidas à dupla prensagem a frio para extração do óleo, produto principal, e da torta, coproduto. Os grãos e tortas foram avaliados quanto à composição bromatológica e ao perfil de minerais. Os rendimentos de extração lipídica foram calculados com base no balanço de massas. O teor de lipídeos nas tortas foi baixo quando comparado aos valores da literatura, o que caracteriza boa eficiência de extração e versatilidade da prensa empregada. A torta de pinhão-manso apresenta fibras como principal componente, com cerca de 1/3 de sua composição total. As proteínas constituem a fração majoritária na torta de nabo-forrageiro, e o crambe apresenta composição balanceada entre fibras e proteínas. As tortas são ricas em potássio, magnésio, cálcio, sódio, manganês, ferro, zinco e boro.Termos para indexação: Crambe abyssinica, Jatropha curcas, Raphanus sativus, biodiesel, composição bromatológica, resíduos agroindustriais. Chemical characterization of seeds and presscakes of physic nut, radish and crambeAbstract -The objective of this work was to chemically characterize the seeds and presscakes of physic nut (Jatropha curcas), radish (Raphanus sativus) and crambe (Crambe abyssinica) after extracting the oil with a mechanical press. Whole seeds of these species were subjected to double cold pressing to extract the oil, or main product, and the presscake, or coproduct. The seeds and presscakes were evaluated regarding proximate composition and mineral profile. The lipid contents in the presscakes were lower when compared to the values presented in previous works, which characterizes good extraction efficiency and versatility of the employed press. Fibers are the most abundant component of physic nut presscakes, and comprise about 1/3 of their total composition. Protein is the largest fraction in radish presscakes, and crambe presents balanced fiber and protein contents. The presscakes are rich in potassium, magnesium, calcium, sodium, manganese, iron, zinc and boron.

“…For example, technical recommendations on appropriate row spacing and plant density are unavailable. There are a few studies about row spacing and plant density (WHITE et al, 1966;LAGHETTI et al, 1995;WANG et al, 2000;PITOL et al, 2010), but for Brazilian growers, these results are only incipient. Therefore, the objective of this study was to evaluate the effects on grain yield and its components in Crambe abyssinica Hochst.…”

Understanding the influence of row spacing and plant density on grain yield and yield components of crambe is critical in order to obtain higher grain yields. Therefore, the objective of this study was to evaluate the effects of row spacing and plant density on grain yield and its components in crambe in two distinct regions of Brazil (Marechal Candido Rondon-PR, MCR-PR, and Botucatu-SP, BTU-SP). Narrow and wide row spacing (0.20 and 0.40 m) combined with four plant densities (15, 25, 35, and 45 plants m -1 ) were evaluated in a randomized block layout with four replications in a 2 × 4 factorial design. The experiment at BTU-SP was run under rainfed conditions with supplementary irrigation, whereas the experiment at MCR-PR was run under rainfed conditions without supplementary irrigation. Both experiments were run in soils classified as Oxisols. There was no interaction between row spacing and plant density. Highest grain yield with supplementary irrigation was observed at 0.20 m row spacing. Without irrigation, row spacing did not affect grain yield owing to the plasticity of crop. The highest grain yield was observed with approximately 30 plants m -1 at both experimental locations. A strong negative correlation was observed between final plant population and number of grains per plant. There was high plant mortality, particularly at high plant densities cultivated under irrigation. Higher mortality occurred because of high intraspecific competition and a larger disease incidence due to the higher humidity in the irrigated experiment. A mechanism of self-adjustment by plant density was observed in crambe, with its intensity dependent on plant density and environmental conditions, such as water and nutrient availability and light incidence.
