- Intervention effect Fertilizer combinations in experiment I increased stem length and leaf number.
- Intervention effect Leaf ash content decreased with the initial fertilizer levels.
- Intervention effect Higher fertilizer levels progressively reduced stem length and leaf number.
- Intervention effect Higher fertilizer levels variably reduced leaf dry weight and ash content against controls.
- Intervention effect Fertilizer combinations variably increased total soluble nitrogen.
- Intervention effect Protein nitrogen increased, stayed unchanged or decreased across fertilizer combinations.
- Intervention effect Total nitrogen and nicotine content increased versus controls.
- Intervention effect Higher fertilizer rates generally reduced protein and total nitrogen.
- Intervention effect Higher fertilizer rates increased nicotine and soluble nitrogen.
- Intervention effect Fertilizer treatment markedly changed the amount and composition of the carbohydrate pool.
- Intervention effect Treated plants had generally reduced chlorine content in both experiments.
