Two field trials were carried out during 1978 and 1979, at Cañete (Lat. 37º54’ S). Eight seeding dates from April to November, and two cultivars, of each winter, alternative and spring wheat types were compared, in a split-plot design, with four replications. Seeding date significantly influenced each and every one of the anaiized variables, in all wheat cultivars. In addition, there was a marked interaction between seeding date and cultivars.
