practice to control stem elongation needed for compact plant production. Daminozide, chlormequat chloride, or paclobutrazol sprays reduce plant height but need to be repeated regularly ( Conover et al., 1968 ; De Baerdemaeker et al., 1994 ; De Graaf
. Therefore, there were 16 replicates for each genotype × treatment level. Plant height at planting was 27.6 ± 0.7 and 25.3 ± 0.5 cm for S. alba and S. tomentosa , respectively, with no significant differences among ecotypes of either species. Some of the

g·ha −1 of GA applied 2 weeks before harvest improved plant height and yields. Dainello et al. (1985) got the best fall spinach yield response with GA 3 at 15 to 20 g·ha −1 applied 7 to 14 d before harvest. Johnson et al. (1989) recommended GA
