Abstract

Abstract Tomato transplants were grown in soil-substitutes of peat moss-Turface and peat moss-perlite. Nutrients were added to the mixtures in factorial combinations by varying the levels of N, P, K, and dolomite. Plants grown in peat-Turface were taller and heavier than those grown in peat-per-lite. In either medium, plants grown with the high level (10 lb./yd 3 ) of dolomite were taller than the plants grown with the low level (5 lb./yd 3 ) of dolomite. Plants grown in peat-Turface contained more N, K, and Ca than did the plants grown in peat perlite. Plants grown in peat-perlite contained more P than plants grown in peat-Turface. The growing medium had no influence on Mg content of plant tops. The highest and earliest yielding plants were those grown in peat-Turface. The 10-lb. rate of dolomite was essential for high early yields in peat-Turface, but the additional increment of dolomite had no effect on early yields for plants grown in peat-perlite. Interactions existed between media and nutrient levels for growth, nutrient uptake, and early yields.
