| Abstract | ||||
| The objectives of this study were to determine the effects of sowing dates and foliar spraying of the micronutrients Iron and Zinc on productivity of the sugar beet variety Halawa (multigerm) in salt affected soil. Therefore field experiments were carried out at the area of Sahl-Eltina south of Port Said, Egypt which known by its salt affected soil during the two growing seasons of 2015/2016 and 2016/2017. Each sowing date was allocated in a separate experiment. The experiments were laid out in randomized complete block design having three replications. The treatments consisted of two sowing dates (August 1st and October 1st) and for micronutrients, without micronutrients, Zinc-EDTA (16 %) in concentration of 1g/l and Fe-EDTA (14 %) in concentration of 1.5 g/l were applied three times at 60, 75 and 90 days after planting. The combined analysis showed that the first sowing date (August 1st) surpassed the second one (October 1st) in all studied characters. Foliar application of Fe-EDTA at concentration of (1g/l) was more effective than foliar spray of Zn-EDTA at concentration of (1.5g/l) in improving root performance (length, diameter and fresh weight/plant) and juice quality as well as increasing root, top and sugar yields/fed compared with without treatment (control). The effect of interactions between sowing dates and foliar application of micronutrients were not statistically significant on the all studied characters. | ||||
