Abstract:
Castor bean (Ricinus communis L.), is a plant belonging to the Euphorbiaceae family and one of the most interesting oil seed crops to develop and study in the Mediterranean basin. The main trait that enhances castor cultivation is its oil content, which is really high, around 40-55% depending on the genotype and area of cultivation. Today’s panorama and policies are pushing towards the exploitation of this crop because it is expected to be a valid alternative to fossil fuels for the production of biofuels, such as biodiesel, and for the valorization and use of abandoned and degraded land. Field experiment was conducted for analyzing the oil yield and oil content of four dwarf hybrids of castor, compared to a local genotype, selected by the University of Catania, Italy. The aim of the study was to evaluate the effect of different sowing dates on the oil content and oil yield of castor seeds. The analysis was conducted on primary and secondary raceme. The oil content was higher in the dwarf hybrids for the primary racemes, whereas for the secondary raceme the most productive one, in terms of oil content was GT. By analyzing also the oil yield (resulted from the multiplication of the oil content by the oil yield), the most productive genotype for the oil yield on average was G4, whereas SW3 was the sowing date with the highest value. Nevertheless, the combination genotype x sowing date had higher result for G3 SW3. Among the parameters studied, the genotype G2 shown a low level of tolerance to the low temperatures.
