Abstract: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 ) … Show more
“…Viana et al (2015), evaluated the yield of the cultivar FMS Brilhante at different sowing densities and obtained average values ranging from 1706.12 to 2118.57 kg/ha. In work with the same cultivar Zoz et al (2018) obtained grain yield ranging from 1176.7 to 1760.7 kg/ha. The values presented by both works corroborate the high productive potential of the crambe genotypes evaluated in this experiment.…”
Crambe’s breeding is still incipient, with few cultivars of interest. The aims of the present study were: i) to evaluate the divergence between 10 genotypes of crambe, through morphoagronomic and quality traits, using multivariate analyses; and ii) to estimate genetic parameters related to these traits. The trial was conducted in a greenhouse, and the experimental data were submitted to multivariate analysis and genetic evaluation. The genotypes differed significantly among them for plant height (PH), stem diameter (SD), number of branches per plant (NB), height of the first productive branch (HPB), mass of 1000 grains (M1000), grain yield (YIELD) and oil productivity (OIL). The experimental coefficient of variation revealed good precision (4.29 to 13.81%). The averages of YIELD (1936.94 kg/ha) and OIL (660.10 kg/ha) were high. The traits presented high estimates of broad-sense heritability on a mean genotype basis (h2 > 73.65). The cluster analysis revealed five clusters of genotypes. YIELD showed the greatest contribution (22.31%) to the diversity among the genotypes, followed by HPB, NB and SD. Genotypes 2 and 4 can be used as parents at future crosses, as they are promising in obtaining segregant populations.

“…In Europe, Crambe achieved an average grain yield of 2.4 Mg ha −1 and an average oil yield of 846 kg ha −1 [52]. The average oil content of the grains was 38% [53] and the thousand-grain mass was 6-10 g [52].…”

Industrial crop cultivation on marginal agricultural land limits indirect land-use change effects that pose a threat to food security. This review compiles results from 91 published crop-specific field trial datasets spanning 12 relevant industrial crops and discusses their suitability for cultivation on unfavorable soil types (USTs). It was shown that the perennial species Miscanthus (Miscanthus Andersson) and reed canary grass (Phalaris arundinacea L.) performed well on USTs with both high clay and/or high sand contents. Information on stoniness (particles sizes > 2 mm), where mentioned, was limited. It was found to have only a small impact on biological yield potential, though it was not possible to assess the impact on mechanization as would be used at a commercial scale. For soils with extreme clay or sand contents, half of the crops showed moderate suitability. The large yield variations within and between crops revealed large knowledge gaps in the combined effects of crop type and agronomy on USTs. Therefore, more field trials are needed on diverse USTs in different climates with better equipment and more consistent measurements to improve the accuracy of potential yield predictions spatially and temporally. Additionally, larger trials are needed to optimize cultivation and harvesting.

Developments in selection and emergence of new varieties and hybrids of oilseeds, which have a better ratio of the fatty acid composition of the oil, make is possible to promote such types of crops as camelina, colza, rapeseed and others. The paper presents an analysis of the quality of new and promising varieties and hybrids of oilseeds, which, according to their morphological and biological characteristics, are successfully cultivated in conditions of the Non-Chernozem Zone of Russia. It is confirmed that oil quality is due to genetic characteristics of the variety and hybrid. The quality of seeds of spring rapeseed Ratnik, Cyclus KL, Curry KL, Salsa KL, Cultus KL, Ozorno, Cebra and other studied varieties and hybrids of the 00 type are close to olive oil in their fatty acid composition and are not inferior to the quality of sunflower oil. There is a high content of important C18:1 oleic acid in oil of rapeseed (59-65 %), and a low content of the total of C16:0 palmitic + C18:0 stearic (5.5-6.0 %). The data on the high quality of camelina oil are presented, which allows the use of varieties Yubilyar and Veles for production of vegetable oil with a high content of unsaturated acids for food purposes. The work discusses the current restrictive norms for the supply of oilseeds and determining the standard weight for oil refining enterprises.
