Four greenhouse experiments were conducted to investigate nutritional relationships between P and Ca in cigar wrapper tobacco. Plants were grown in a soil‐peat mix in 2 of the experiments and in sand cultures in the others. Levels of P and Ca in the nutrient media were varied. Plant concentration and uptake of P and Ca were determined to evaluate nutritional relationships between the two elements. An inverse relationship between P and Ca concentrations in cigar wrapper tobacco was apparent in all 4 experiments. Phosphorus appeared to decrease Ca uptake by cigar wrapper tobacco when added in increasing amounts.
