“…The seed yield increase in irrigated CB fields is small compared with that of other common crops cultivated in the same area, suggesting that it is more suitable for low-input, arid environments [83,86,100]. Castor bean can also grow well with wastewater irrigation [3,24,101]. Wastewater is an alternative water source being recently exploited to irrigate biofuel crops without depleting the already scarce water resources.…”

Biofuel Production with Castor Bean: A Win–Win Strategy for Marginal Land

The urgency to reduce resource depletion and waste production is expected to lead to an economy based on renewable resources. Biofuels, for instance, are a great green alternative to fossil fuel, but they are currently derived from edible vegetable oils such as soybean, palm, and sunflower. Concerns have been raised about the social–economic implication and ecological impacts of biodiesel production. Cultivating new lands as biodiesel feedstock rather than food supply, with the consequent increase in food prices, leads to so-called indirect land-use change (ILUC). Establishing bioenergy crops with phytoremediation ability on contaminated soils offers multiple benefits such as improving soil properties and ecosystem services, decreasing soil erosion, and diminishing the dispersion of potentially toxic elements (PTEs) into the environment. Castor bean is an unpalatable, high-biomass plant, and it has been widely demonstrated to possess phytoremediation capability for several PTEs. Castor bean can grow on marginal lands not suitable for food crops, has multiple uses as a raw material, and is already used in biodiesel production. These characteristics make it perfect for sustainable biodiesel production. Linking biofuel production with environmental remediation can be considered a win–win strategy.

“…Different from other oilseed crops, the interest toward this plant has increased exponentially in recent years due to its high seed oil content (around 35-65%) and a high percentage of ricinoleic acid (85-90%). The latter, in particular, has lately been re-evaluated for its wide range of industrial applications [7].…”

Germination Response of Different Castor Bean Genotypes to Temperature for Early and Late Sowing Adaptation in the Mediterranean Regions

et al. 2023

Germination of castor seeds of seven dwarf hybrid genotypes, compared to a ‘Local’ genotype, selected from a Tunisian population by the University of Catania well adapted to the Mediterranean environment, were studied at six different temperatures (8, 12, 16, 25, 32, and 40 °C). The results indicate that the optimal temperature (25 °C) and near-optimal temperature (32 °C) are the best temperatures for ensuring castor germination (final germination percentage (FGP) ≥ 82.81%). Furthermore, these temperatures positively influenced the vigour index (VI) and the radicle elongation. At a temperature of 8 °C, no germination occurred, while temperatures of 12 and 40 °C negatively affected the seed germination, which, in some genotypes, was null or negligible (<21.25%). A temperature of 16 °C allowed good results to be reached for the FGP and the other considered parameters. Overall, the dwarf hybrids performed better at high temperatures than at low temperatures, thus, making them suitable for late sowings, with the exception of the genotype ‘C1020’, which resulted the best performance at 16 and 40 °C, being suitable for both early and late sowings. On the other hand, the ‘Local’ castor genotype, being the best-performing genotype at 12 and 16 °C, and the most tolerant to low temperature (base temperature (Tb) 12.1 °C), could be used in the early sowing in spring.

“…K means clustering is one of the e cient tools in grouping genotypes and had many practical applications (Singh and Singh 2012; Kaur and Kaur 2013). Hence clustering was done K means algorithm which assembled the genotypes into clusters based on similarities and dissimilarities between them (Yadav and Anjani 2017). In order to avoid the dominance of single trait over the other during cluster formation, data was normalized and subjected to clustering.…”

It is axiomatic that castor (Ricinus communis L.) is an industrially important oil crop with wide use. Augmenting oil yield from seeds beyond a certain limit is challenging and cumbersome. Hence, it is imperative to improve the seed yield by breeding elite hybrids/varieties. Morphological description of 208 castor genotypic population for eight qualitative was carried out and considerable polymorphism existed among the collection. Maximum genotypes were R2 and R3 morphotypes because of the dominant nature of red stem color and blooming nature. K means clustering separated the genotypes into 20 clusters with Cluster 4 and 20 as well separated one. Cluster 4 could serve as female parent since the cluster was composed of pistillate lines and cluster 20 as male parent during hybridization. Path coefficient analysis supported the correlation coefficient that effective spike length and capsule weight showed high positive direct effects with seed yield. Also, the analysis revealed primary spike length and effective length of primary spike as the variables with the largest weightage. The first four components accounted for 75.95% of the variation cumulatively. The components were rotated with varimax rotation and the variability contribution was similar to the normal (76%). High communality values specified the reliability of the studied variables in explaining the total variation. Considering both cluster analysis and PCA, the genotypes SKP 84, DPC 19, JP 65, JC 3, JC 26, RG 27, ICS 210 and RG 3477 possessed immense value as parents in breeding varieties/hybrids to meet out the global oil demand.
