Produção e renda bruta de mandioquinha-salsa, solteira e consorciada com cenoura e coentro

Foram estudadas a mandioquinha-salsa ‘Amarela de Carandaí’- M, a cenoura ‘Brasília - Ce o coentro ‘Tipo Português’- Co em cultivos solteiros e os consórcios MCe e MCo. Os cinco tratamentos foram arranjados no campo, no delineamento experimental de blocos casualizados, com cinco repetições. A colheita da cenoura foi aos 95 dias após a semeadura; a do coentro, aos 112 dias e a da mandioquinha-salsa, aos 247 dias após o plantio. A altura das plantas (42,3 cm) e as massas frescas de raízes total (9,07 t ha-1) e comercial (6,55 t ha-1) da cenoura no consórcio MCe tiveram aumentos significativos de 4,4 cm; 2,34 e 1,73 t ha-1, respectivamente, em relação às plantas cultivadas solteiras. No coentro, a altura (24,0 cm) e a massa fresca de folhas (2,98 t ha-1) das plantas solteiras foram significativamente maiores que as consorciadas. Na mandioquinha-salsa, houve influência significativa da forma de cultivo e os maiores valores de massas frescas, em t ha-1, de folhas (17,84), rebentos (4,07), coroas (3,99) e de raízes totais (14,04), comerciais (10,46) e nãocomerciais (3,58) foram obtidos no cultivo solteiro. O consórcio MCe foi considerado efetivo (RAE = 1,47) e o MCo foi inefetivo (RAE = 0,76). A renda bruta indicou que os dois consórcios não devem ser recomendados para o produtor de mandioquinha-salsa porque induziriam perdas de R$ 8.650,00 e R$ 7.011,25, respectivamente.‘Amarela de Carandaí’ Peruvian carrot (M), ‘Brasília’ carrot (Ce) and ‘Tipo Português’ coriander (Co) were studied in monocrop system and intercropped with carrot and coriander. Five treatments were arranged at field in a completely randomized block design with five replications. Harvest of carrot occurred 95 days after sowing; coriander harvest occurred 112 days after sowing; and the Peruvian carrot harvest, 247 days after planting. Plant height (42.3 cm) and fresh masses of total (9.07 t ha-1) and commercial (6.55 t ha-1) roots of carrot in the MCe intercrop had significant increases of 4.4 cm, 2.34 and 1.73 t ha-1, respectively, in relation to those plants in monocrop system. Coriander height (24.0 cm) and fresh mass of leaves (2.98 t ha-1) of plants from monocrop system were significantly higher than those intercropped. As for Peruvian carrot, there was significant influence on cultivation and the highest values of fresh mass, in t ha-1, of leaves (17.84), shoots (4.07), crows (3.99) and total (14.04), commercial (10.46) and noncommercial (3.58) roots were obtained with the monocrop system. The MCe intercrop was considered effective (LER= 1.47) and the MCo was ineffective (LER = 0.76). Gross income showed that both intercroppings are not recommended for the Peruvian carrot producer since they induced losses of R$ 8,650.00 and R$ 7,011.25, respectively
