Drought, as well as water scarcity, are the main limiting factor in the arid and semi-arid regions of the world such as Iran. Autumn cultivation can be a solution provided that the upcoming long and cold temperature does not limit the sugar beet development. This paper aims to consider the possible autumn sowing dates of the common sugar beet cultivars in Marvdasht so that the environmental conditions fit the growth and development.
Materials and Methods
A split-split-plot field experiment with the randomized complete block design (RCBD) in three replicates was conducted in two agronomic years (2016-7 and 2017-8) in Marvdasht. Three sowing dates 16 September, 7 October, and 27 October) were assigned to the main plots and two cultivars (Gidae and Levante) consisted of the sub-plots. Three harvest dates (1 May, 26 May, and 20 June) were also assigned to the sub-sub-plots.
Results and Discussion
The statistical analysis showed that the two-factor interaction of sowing and harvest dates were significant on the root yield (alpha <0.01). the mean comparisons of the treatments showed that the lowest yield was obtained at the sowing date of 27 October and the harvest date of 1 May (32.95 ton/ha). On the other side, the highest yield (75.75 ton/ha) was acquired with the interaction of the 16 September sowing date and 20 June harvest date. Bolting did not occur with the second and third sowing dates while it happened with the first sowing date whether the cultivar was. Bolting percentage at the first sowing date was also affected by delays in harvest dates. The third-factor interaction was significant on extractable sugar percent.
Conclusion
To sum up, the results of the paper showed that sowing dates of 16 September With the corresponding harvest date at 26 May are suggested for the autumn sugar beet cultivation in Marvdasht that can maximize the extractable sugar and root yield
