Abstract
ABSTRACT The yield of coriander (Coriandrum sativum L.) in response to changes in plant density was monitored to estimate the economic optimum planting density and to identify the plant component with the greatest impact on final yield, In growth trials near Buenos Aires, Argentina, biomass and grain yield varied asymptotically with plant density for both Argentinean and European land races. The plant density necessary to obtain maximum biomass and grain yields was higher in a wet year (1993) than in a dry year (1991). At the same seeding rate, maximum total biomass was higher for an early seeding date (June) than for a later seeding date (July). Early and late seeding dates had no effect on grain yields. The number of umbels and grains per plant decreased quadratically with plant density. Grain number was the yield component that best explained yield.
