INVESTIGATING OF CULTIVATING THE AUTUMN SUGAR BEET IN FARS PROVINCE (ZARGHAN), IRANAdibifard1, N., Habibi1, D., Bazrafshan, M., Taleghani, D. andIlkaee, M.N.
As water is the most restrictive factor in national agricultural production, it is necessary to take decrease water consumption and increased water use efficiency in crop production into consideration .Now, spring sugar beet production areas are concentrated in the region with water limitation and hence, the increase in spring production areas concentrates the principal of water and soil conservation. So it is necessary that we increase the production efficiency in the unit area in this region .Using new region for autumn sugar beet sowing allows the increase in warm and semi- warm beet production areas. The majority growing areas of spring sugar beet meet the limited availability of water. Increased cultivation of sugar beet in most of these areas is not consistent with the preservation of water resources and soil, so we need to develop new areas of autumn sugar beet there. Using of new zones leads to fall of sugar beet production, creates the possibility that the area under cultivation increased in warm and semi-warm region. To develop sugar beet production in province of Fars the study was conducted in agriculture and natural resources research institute zarghan area in strip split plot based on randomized complete Block Design with six replication during 2015-2016. Two sowing dates (October 8 and November 13) in main plot and four cultivars (Azaba, Giada, Spartak and Supryma) in sub main plot were evaluated. Result showed significant effects of sowing dates on white sugar yield in 0.05 level. The results showed that sowing date had a significant effect on the performance of white sugar yield at the level of 0.05. The highest white sugar yield of early planting (17 October) amounts to 14.63 and 15.1 t/ha respectively in Azaba and Supryma was obtained. The highest root yield obtained from early sowing date and varieties of Spartak (54286 kg per hectare) and Gyada (50952 kg/ha), respectively. The lowest bolt percentage were observed from second sowing date in all four cultivars with zero percentage of bolting. The highest bolting percentage were observed in Spartak cultivar in the first sowing date. The number of bolting plant in May 21 were detected in each cultivar and were percent of all plants. In harvesting time qualities parameters such as sugar content ,Na ,K, harmful nitrogen, molasses sugar content, white sugar content, Ecs and root yield were determined for determining harmful effect of bolting at production quality. In harvesting time number of root, root weight and shoot weight were measured. According toresults and agro climatic condition of zarghan area in fars province it seems that after further study this region will presented as a suitable region for planting autumn sugar beet.
