| Abstract | ||||
| Two field experiments was conducted at El-Serw Agricultural Research Station, Damietta Governorate, Egypt during 2012/2013 and 2013/2014 seasons. The objective of this investigation was aimed to study the effect of three sowing dates (mid September , first October and mid October) and soil application of sulphur fertilizer in the form of Calcium poly sulfide (CaSO4 30% sulphur) at the levels of (zero, 100 and 200 kg CaSO4/fed., mixed with soil) which were applied at age 45 and 75 day, for Soltan cultivar. A split plot design with four replicates was used. The main plots were assigned to sowing dates, whereas, soil application with CaSO4 were distributed in the sub plots. The results can be summarized as follows:- 1- Lating planting sugar beet until mid October due to significant increase in root dimension and root fresh weight/plant in addition, applied sulphur at rate (200 kg CaSO4 30% sulphur) take the same trend of lating planting date for the same characters. 2-Significant increase was obtained in quality characters as (TSS, Sucrose and Purity %) in both seasons resulted from planting at mid October and addition 200 kg calcium poly sulphur. 3- The highest values of all characters under study resulted from addition 200 kg sulphur for lat planting date in both seasons. 4- Significant decrease in values of impurities (K, Na and a-amino N.) were found resulted from lat planting up mid October and fertilization with 200 kg sulphur in both season. | ||||
