Resumo:
Currently the culture of castor has emerged as a of the main raw material for the
production of oil, especially in the Northeast, however many factors has hampered
the establishment of this tilth in new areas among which is the lack of cultivars
adapted to each region of cultivation. This study was developed with the objective of
identify castor’s cultivars with adaptation to the Paraíba Sertão. The study was
conducted on Sítio Monte Alegre countryside of municipality of Pombal - PB, the
experimental design was the of random blocks with seven treatments composed by
BRS Northeastern; Paraguaçu BRS; BRS Energy; Guarany AL-2002, IAC 2028, IAC
Guarany and IAC 80, with four replications were evaluated characteristics of growth,
production, yield and oil content in the seeds. From the results was registrated a
higher grain production per plant in Northeastern BRS and higher grain yield among
cultivars long cycle, in relation to early maturity cultivars the IAC 2028 got higher
productivity, the primary raceme may represent more than 40% productivity in
cultivars of early maturity, the higher oil content in seeds was observed in BRS
Energy also gave higher oil yield among the seven cultivars. Nevertheless, we
believe that further studies should be performed at different times and forms of
management to identify with greater precision farming which best fits the region.
