Other claims from this paper (9)
- Intervention effect Seedling growth was markedly better in nutrient solution than the other media.
- Observation Growth and nitrogen, phosphorus and potassium contents differed significantly by 7–11 days.
- Intervention effect Soybean seedlings in rolled towelling had 38% of nutrient-solution dry weight on day 15.
- Intervention effect Sorghum seedlings in rolled towelling had 36% of nutrient-solution dry weight on day 15.
- Intervention effect Growth in deionised water was poor and most seedlings began dying by day 15.
- Association Poor growth in deionised water was associated with potassium leakage.
- Recommendation Vigour tests should provide adequate nutrition.
- Recommendation Seedling growth in nutrient solution at optimum temperature for about 15 days can measure potential growth and vigour.
- Recommendation Comparing growth in nutrient solution and inert medium can indicate seed-lot nutrient status.
