Yield and gross income of bunching onion and coriander in monocrop and intercrop systems

Abstract

The objective of this work was to determine yield and income of ‘Todo ano’ bunching onion and ‘Asteca’ coriander, which were carried out in monocrop and intercrop systems with three (Ce3 and Co3) and four rows planted per plot. The work was developed in Dourados-MS, Brazil, between July 13th, and September 15th, 2004. Average yield of fresh mass of bunching onion plants under monocrop system had significative increase of 0.64 t ha-1 (92.75%) in relation to those under intercrop system (0.69 t ha-1). For coriander, yield of fresh mass of plants under monocrop system and with four rows per plot had significative increase of 1.43 t ha-1 (41.21%) in relation to those under three rows (3.47 t ha-1). Land Equivalant Ratio (LER) for bunching onion and coriander intercropped were superior in 21% (Ce3Co4) and 56% (Ce4Co3) in relation to monocrop system. For bunching onion producer, both intercrops were economic viable, but Ce4Co3 could have induced a higher gain per hectare (R$ 3,243.30). By the other side, for coriander producer, Ce3Co4 intercrop was the worst, because, although LER had been superior to 1.00, it could induce loss per hectare of R$ 99.42. Ce4Co3 intercrop was the best because it could induce a gain of R$ 777.77.
