This study aimed to quantify forage yield, economic performance, biological efficiency and competitive ability in cactus intercropped with millet, compared with their monocrops, both with and without mulch, under irrigation. The experiment was conducted over two years in semi-arid of Brazil. The experimental design was of randomised blocks with four replications and six treatments: monocropped cactus without mulch; monocropped cactus with mulch; monocropped millet without mulch; monocropped millet with mulch and cactus intercropped with millet, with and without mulch. The individual yields of fresh (270 t ha
−1 ) and dry (23 t ha−1 ) matter in the cactus were not affected by the mulch or by intercropping. Mulching improved the individual yields of fresh (69.7 t ha−1 ) and dry (23.4 t ha−1 ) matter in the monocropped millet. Total dry matter was greater in the intercropping systems, both with (32.8 t ha−1 ) and without (31.4 t ha−1 ) mulching, being the average monetary advantage index equal to 8 404 BRL ha−1 . The cactus-millet configuration, irrespective of the use of mulch, but irrigated in dry environments or during dry periods of the year, is more advantageous than the monocrops, because it promotes gains in production and food diversity for meeting the demand of the herd.
