The trial was carried out La. Platina Experimental Station, Instituto de Investigaciones Agropecuarias, located at the Metropolitan Region, during 1988-1989 season. The objectives were to determine the elfect of five pianting dates on yield and bulb size in two shallot cultivar. The trials were set in asplit-plot design wtth lour replications. The treatments were the two cultivar: Jermor and Limador. The subtreatments were the five planting dates: June 23, July 22, August 22, September 26 and October 25, 1988. As the planting date was delayed, in both cullivars, the marketable and exportable yields (ton/ha) tended to decrease. The highest yieids were reached in the two earlier planting dates, Jermor showing a beller response than Limador. Shallots stablished in June and July reached the highest exportable percentages, which were 85.4 and 87.1% in Jermor and 77.8 and 77.0% in Limador, respectively. The greatest amount of discardedbulbs was obtained in September planting date with Jermor and in July planting date with Limador.
