- Intervention effect The 3.32-pound potassium rate gave the greatest total dry weight and survival of tobacco seedlings.
- Intervention effect Dry weight of tops, plant height and leaf area tended to decrease with each increment of potassium above 3.32 pounds.
- Mechanism High potassium levels increased soluble salts in the muck to a level that retarded tobacco seedling growth.
- Observation Tobacco plants took up more potassium than the 3.32-pound rate supplied, as the muck released large amounts of potassium.
- Intervention effect Chlorine in the fertilizer increased total ash and potassium content of tobacco seedlings.
- Intervention effect Chlorine in the fertilizer tended to decrease nitrogen content of tobacco seedlings.
- Intervention effect Potassium and chlorine had no effect on the weight of tobacco roots or on relative turgidity.
