Abstract

 In order to study the effect of planting date on the YIELD of early maturity POTATO cultivars in AUTUMN CULTIVATION in Khuzestan province an experiment was conducted for two years (1997 and 1998)at Behbahan Agricultural Research Station. The experimental design was a strip plot in randomized complete block design with three replications. Cultivars (6 cultivar) were considered as horizontal plots, and planting date (5 planting dates) as vertical plots. In the first year (1997), cultivars Ajiba, Marfona, Timate, Stetose, Hertha and MNlO5 were planted in six dates of Sep. 29, Oct. 8, Oct. 23, Nov. 7, and Nov. 22. In the second year (1998) Ajiba, Marfona, Timate, Bona, Concorde and Romano were planted in Sep. 15, Sep. 23, Oct. 8, Oct. 23, and Nov. 7. In the first year frost occurred in Jan. 14, and all plants were killed, but in the second year, with no frost, plants continued to grow until the mid February. Analysis of variance on YIELD data showed that differences among cultivars, planting dates and cultivar x planting date interactions were highly significant in two years of experiment. According to the obtained results, the best planting date for POTATO in AUTUMN CULTIVATION in Khuzestan is the early October and the best cultivar is Ajiba.
