Other claims from this paper (12)
- Intervention effect Sulfur fertilization had no effect on kohlrabi tuber yield.
- Intervention effect Sulfur fertilization had an insignificant effect on nitrogen content in tubers and leaves.
- Observation Sulfur concentration in tubers ranged from 0.59 to 0.64%.
- Intervention effect Sulfur fertilization increased sulfur concentration in leaf tissue.
- Observation Nitrate content was higher in tubers than leaves.
- Intervention effect Increasing soil sulfur significantly reduced tuber nitrate concentration by 42.2-53.6%.
- Intervention effect Increasing soil sulfur reduced cysteine plus methionine concentration by 16-28%.
- Observation Valine, tyrosine, aspartic acid and serine concentrations remained constant.
- Intervention effect Threonine, isoleucine and leucine levels decreased by 37 to 9% across S0, S1 and S2 treatments.
- Intervention effect Arginine, total essential amino acids and alanine decreased across S0, S1 and S2 treatments.
- Intervention effect Histidine concentration increased with sulfur fertilization.
- Recommendation The authors recommend sulfur fertilization to stabilize yield and reduce nitrate in edible kohlrabi parts.
