Other claims from this paper (14)
- Intervention effect Raising nitrogen from 100 to 160 kg N/fed increased root weight by 24.77% in the second season.
- Intervention effect Raising nitrogen increased plants at harvest by 4.05 thousand plants/fed in the first season.
- Intervention effect Raising nitrogen increased plants at harvest by 2.89 thousand plants/fed in the second season.
- Intervention effect Raising nitrogen increased root yield by 7.22 tons/fed in the first season.
- Intervention effect Raising nitrogen increased root yield by 8.34 tons/fed in the second season.
- Intervention effect Excessive nitrogen lowered sugar beet sucrose content, juice purity and extractable sucrose.
- Intervention effect Increasing nitrogen from 100 to 120 kg/fed increased extractable sugar yield by 29.08% in the first season.
- Intervention effect Increasing nitrogen from 100 to 120 kg/fed increased extractable sugar yield by 31.97% in the second season.
- Intervention effect Further nitrogen above 120 kg/fed had no significant effect on sugar yield.
- Intervention effect Splitting nitrogen into four equal doses significantly increased individual root weight and plants at harvest.
- Intervention effect Late nitrogen application in four doses gave the highest root yield.
- Intervention effect Early nitrogen application in two equal doses improved sucrose, purity and extractable sucrose.
- Intervention effect Splitting 160 kg N/fed into four equal doses gave the highest root yield.
- Recommendation The authors recommend splitting 120 kg N/fed into four equal doses for high sugar yield.
