This study attempts to evaluate the effects of planting date and spraying CCC on some biochemical characteristics and qualitative and quantitative yield of sugar beet. It has conducted an experiment, using a Split factorial based on randomized complete block design with three replications in 2015-2016 growth season in field experiment of university of Abourayhan, Tehran University. The treatments include planting date (2nd of October and 22nd of October) as the main factor and cultivars (Suprima and 9597) and foliar spraying (1000 ppm) / non-application of CCC as sub plots. The results show that the highest percentage of bolting (54.58%) and sodium content (equivalent to 9.16 mEq / 100 g of sugar beet pulp) take place on October 2, while the highest root yield (26.15 ton per hectare) and white sugar yield (equal to 1.44 tons per hectare) happen on October 22. Also, it has been observed that most values of the studied traits (except bolting percentage and sodium content of sugar beet pulp) have occurred through the cultivation of Suprema with CCC spraying. Overall, it can be concluded that the best conditions to determine the best root and sugar yield in the area of research, on 22nd of October, the Suprima and application of 1000 ppm are recommended in order to cultivate sugar beet in the Pakdasht area.

In order to investigate the effect of different nutrition systems (chemical, organic, chemical+organic, and control) on quantitative and qualitative characteristics of sugar beet in various planting methods (direct planting, potting, and transplanting), an experiment has been conducted as split plot in randomized complete block design with three replicates between 2016 and 2018 in a field, 75 km northwest of Sabzevar. The results show that in the first year, the highest root yield (84.34tha-1) has been obtained from the potting method and chemical along with organic fertilizer application. In the second year, the highest yield (82.96tha-1) belongs to the chemical and organic fertilizer treatment in transplanting method. In both years, the highest sugar content has been obtained from control treatment and direct planting, with transplanting method having the highest sugar yield in both years (13.29 and 14.44 tha-1, respectively). Transplanting and potting method have had more root impurities than direct cultivation. Among nutrition systems, the highest root impurities is obtained in the combination of chemical and organic treatment. Direct culture and control produce the highest alkalinity index. Overall, despite the increase in root impurities in transplanting or potting along with chemical with organic treatment, these treatments produce the highest sugar yield. Accordingly, chemical and organic fertilization along with transplanting could be recommended to produce the highest root and sugar yield.
