Effect of seed priming and transplantation on some morphological characteristics, sugar yield and yield components of sugar beet

In order to study effect of seed priming and transplantation on quantitative and qualitative characteristics of sugar beet, an experiment was conducted on a farm land in Naghadeh-Western Azerbaijan at 2018 growing season. The experiment design was split plot based on randomized complete block with four replications. Type of planting method (direct and transplant system) assigned to main plots, and priming (salicylic acid, gibberellic acid, hydroperiming and control (non-priming) assigned to sub plots. The results showed that the effect of planting system was significant on the amount of root sodium, alkalinity, sugar content, coefficient of sugar extraction, shoot dry weight, white sugar yield and molasses sugar content. The effect of priming on all studied traits was significant. Interaction of two treatments was also significant on root potassium, sugar content, white sugar content, sugar extraction coefficient, shoot dry weight, root yield, white sugar yield and molasses sugar content. In this study, the lowest root sodium content (3.02 ppm), root alkalinity (3.09%) were assigned to transplanting system, also the highest chlorophyll index (36.17%) and the least nitrogen (1.92%), alkalinity percentage was recorded for  Hydro priming treatment (3.24%).The results showed that the highest sugar content  (18.17%), white sugar content (16.14%), sugar extraction (88.96%), shoot dry weight (3.64 kg / ha), root yield ( 82.17t/h), sugar yield (14.89 t/ha) and pure sugar yield (12.24%) and lowest root potassium content (2.52 ppm) were allocated to transplanting system with hydropriming treatment.
