Summary
Two Ca-efficient and 3 Ca-inefficient tomato strains were grown for 18 days in nutrient solutions with NH4-N:NO3-N ratios (%) of 0:100, 50:50, or 90:10 and with 40 mg of total Ca++. When NH4-N nutrition was used, efficient strains exhibited Ca-deficiency symptoms sooner or produced less dry matter than inefficient strains. The greatest reductions in dry weight production occurred in solution pH and in % of Ca in plant tissues occurred between 0 and 50% NH4-N nutrition. Ratings of Ca efficiency varied according to the proportion of NH4-N in the nutrient solutions. [AS]
