Abstract

This study aimed to evaluate the effects of planting date and spraying CCC on some biochemical characteristics and qualitative and quantitative yield of sugar beet. Therefore, the experiment was conducted 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. Treatment were planting date (2 October and 22 October) as the main factor and cultivars (Suprima and 9597) and foliar spraying (1000 ppm) / non-application of CCC as sub plots. The results showed that the highest percentage of bolting (54.58%) and sodium content (equivalent to 9.16 mEq / 100 g of sugar beet pulp) were observed in 2 October and the highest root yield (26.15 ton per hectare) and white sugar yield (equal to 1.44 tons per hectare) were obtained in 22 October. Also, it was observed that most values of studied traits (except bolting percentage and sodium content of sugar beet pulp), were occurred by the cultivation of Suprema with CCC spraying. overall, the conclusion that the treatments, the best conditions to determine the best root and sugar yield in the area of research, the date of 22 October, the Suprima and application of 1000 ppm and recommended in order to cultivate of sugar beet in the Pakdasht area.
