Cactus pear is one of the most cultivated plants in the Brazilian semi-arid region since its implantation. Despite its high adaptability in areas with scarce rainfall, it is vulnerable to diseases and pests, the most important being the carmine cochineal (Dactylopius opuntiae Cockerell) which significantly destroyed palm groves in the northeastern semi-arid region, making it the main stalemate in oil palm cultivation. For this reason, this research aimed to evaluate the performance of forage cactus species Opuntia sp., Opuntia stricta, Nopalea cochenillifera, considered resistant to the referred pest, implanted in a conventional way, comparing them to the new cultivation system over the soil in a period water deficit. The experiment was conducted in the municipality of Jaçanã, Rio Grande do Norte. An experimental design was adopted in randomized blocks, in a factorial scheme with six treatments named Palma baiana conventional cultivation; Bahia palm cultivation system on soil; Conventional cultivation Mexican palm; Mexican palm cultivation system on the ground; Sweet palm conventional cultivation and Sweet palm cultivation system on the ground and duration of 12 months. The results showed that the performance of the varieties during the dry season was similar in both cropping systems, indicating that plant development is more related to their morphology than to the cropping system. The two cultivation systems provide similar performance, but the soil cultivation system is recommendable and innovative due to cost savings and ease of implantation of the crop.
