Castor has emerged as an oilseed species capable of meeting the demand of the Brazilian market.Thus, there is a need for studies to evaluate the different growing conditions that this species can be cultivated in order to subsidize their production. The study aimed to evaluate the influence of different growing conditions on agronomic performance of seven castor bean cultivars grown in Savanna-Pantanal ecotone region. The trial was conducted at Universidade Estadual de Mato Grosso do Sul, Aquidauana Campus. Treatments consisted of seven castor bean cultivars (BRS Energia, IAC-2028, IAC-Guarani, BRS Nordestina, BRS Paraguaçu, IAC-80 and IAC-226) and three growing conditions (with weed control and without topdress nitrogen; with topdress nitrogen at 80 kg ha -1 and with weed control; without weed control and absence of topdress nitrogen) in two agricultural years (2011 and 2012), arranged in randomized block design with three replications in factorial arrangement (7 x 3 x 2). The following variables were evaluated: plant height, stem diameter, number of bunches, number of fruits and fruit yield. The cultivars BRS Energia, IAC 2028, IAC Guarani and BRS Paraguaçu obtained greater fruit yield. Topdress nitrogen and weed control provided to cultivars the highest stem diameter, number of bunches, number of fruits and fruit yield.

“…From its seeds is extracted an oil of excellent properties, having wide use as industrial input and several applications. The main product which is obtained from the industrialization of castor is the oil, which has industrial uses for the manufacturing of paints, varnishes, soaps, synthetic fibers, plastics, dyes, aniline and lubricants (Torres et al, 2015). Castor oil is unique among vegetable oil because it is the only commercial source of a hydroxylated fatty acid or ricinoleic acid (Serverino et al, 2012).…”

With increasing global energy demands, the production of biofuels has been gaining economic importance, with the castor oil plant being one option for the production of biofuel. This study was performed on irrigated cultivation of the castor oil plant, variety IAC 2028, from March to October 2011, in Lavras, Minas Gerais, Brazil, with the following aims: a) to characterise and estimate the sub stages and stages of the crop in days after sowing (DAS) and in growing degree days (GDD) and; b) determine a phenological model of development that describes the vegetative and reproductive behavior of the crop cycle. The experiment was conducted under optimal conditions of irrigation and fertilisation. To determine the phenological model, 15 sub stages and 4 stages of the crop were defined and estimated according to the periodic quantification of variables such as the number of leaves, leaf area, soil cover, and periods of floral initiation, anthesis, bean formation, and maturation by raceme order. We concluded that: a) the sub stages were well characterised and estimated, in particular Vo, A2, M2, and M3, which closed stages I, II, III, and IV with nearly 42, 65, 87, and 100% of the thermal power required by the crop during the lifecycle, respectively; b) the phenological model of the sub stages was determined satisfactorily in GDD; and c) the plant and reproductive sub stages were not completely distinguishable, and the maximum soil cover in M1 indicated that greater productivity could occur with a population increase.
