EFFECT OF PLANTING DATES, NITROGEN LEVELS AND BIOFERTILIZATION TREATMENTS ON: 1: GROWTH ATTRIBUTES OF SUGAR BEET (Beta vulgaris, L.)
This study was carried out during 1998/99 and 199912000 at EI-Serw region in Northen Faraskour district Damitta Governorate to investigate the effect of planting dates, nitrogen levels and biofertilizatiopn treatments as well as their interaction on growth of sugar beet (Beta vulgaris, L.) variety Top. The main finding obtained from this investigation could be summarized.as follows:
- Root fresh and dry weights, foliage fresh and dry weight and leaf area index (at 120 and 150 days from planting), crop growth rate, relative growth rate and net assimilation rate had significant effect by planting dates in both seasons. The highest values for growth characters were obtained by planting beet on 15th of October.
- Raising nitrogen fertilizer levels from 0 to 20, 40, 60 and 80 kg Nlfad significantly improved all growth characters (root fresh and dry weight, foliage fresh and dry weight, LAI, CGR, RGR and NAR) at the two samples in both seasons. Increasing nitrogen fertilizer levels up to 80 kg NJfad resulted in the highest means of all growth measurement as previously mentioned. Vice versa. sugar beet plants growing without nitrogen fertilization (control treatment) were induced the lowest ones of two samples in both seasons .
• The obtained results obvious that. root fresh and dry weights. foliage fresh and dry weights. LAI, CGR. RGR and NAR in both samples and seasons had a significant effect by biofertilization treatments and the results showed that the highest measurements were achieved from treating beet seeds with Rhizobacterin.
·The interaction between planting dates and nitrogen levels had significant on root fresh and dry weights. foliage fresh and dry weights and leaf area index. The interaction between planting dates and biofertilization treatments had significant effect on fresh and dry weights of foliage fresh and dry weight (at 120 and 150 days from planting) and leaf area index.
