EFFECT OF PLANTING DATES, NITROGEN LEVELS AND BIOFERTILIZA TION TREATMENTS: 2: YIELD, YIELD COMPONENTS AND QUALITY OF SUGAR BEET (Beta vulgaris, L.)
Two field experiments were carried out at EI-Serw region in Northern Faraskour district Damitla Governorate to investigate effect of planting dates, nitrogen levels and biofertilization treatments as well as their interactions on yield and quality of sugar beet (Beta vulgaris, L.) variety Top.
The main results could LJe summarized as follows:
Some yield components character i.e. root length, root diameter, root fresh weight, foliage fresh weight, and root /top ratio (in the second season) were exerted a significant effect as a results from planting dates treatments. The treatment from planting dates which gave the high values was planting on 15th of October of all yield components except root diameter (in the second season only) and rootltop ratio in both seasons.
In the first season root quality characters (TSS, Sucrose and juice purity %) were insignificantly affected due to the planting dates treatments. The highest values of yield quality characters were planting beet on 15th of October over both seasons).
Planting dates treatments had significant effect on root yield, top yield, sugar yield and harvest index. Planting dates on 15th of October gave the highest values of yield characters except harvest index.
- Raising nitrogen fertilizer levels from 0 to 20, 40, 60 and 80 kg N/fad showed a significant increase on all yield components and yield in both seasons except root/top ratio resulted from fertilizing beet with 40 kg Nlfad. Vice versa the highest values of TSS, sucrose and purity % were obtained from control treatments (without N-fertilizing) in both seasons.
- Biofertilization treatments had significant effect on all yield components and yield and the best treatment with biofertilizer was rhizobactein treatment except root /top ratio were obtained from uninoculation seeds.
- TSS %, sucrose % and juice purity %, the highest values of these characters were obtained with uninoculation treatment (control). The interaction between planting dates and nitrogen levels had significant effect on all yield components and yield characters except root ftop ratio.
- The interaction between planting dates and biofertilization treatments had significant effect on root diameter (in the first season), foliage fresh weight in the second season (at harvest), juice purity (in the first season only), root, top and sugar yields.
- The interaction between nitrogen levels and biofertilization treatments had significant effect on all yield components, yield quality and yield except root /lop ratio, TSS <in the first season), purity 5 and sugar yield (in the first season.
- The interaction among planting dates, nitrogen fertilizer levels and biofertilization treatments had Significant effect on root diameter, root and foliage fresh weights, root and top yields.
