Yield and gross income of Peruvian carrot in monocrop system and intercropped with carrot and coriander - DOI: 10.4025/actasciagron.v29i4.424

Abstract

‘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.
