Sorghum (Sorghum bicolor (L.) Moench) genotypes were grown in nutrient solutions and in solis at low P under greenhouse conditions to determine genotypes differences for dry matter yields, P concentrations and contents, dry matter produced per unit P, P distribution amos plant parts, P uptake rates, and intact root phosphatases activities. Genotypes grown in nutrient solutions with organic sources of P (ethylammonium, glyceryl-, and phenyl-phosphates) produced as much dry matter as plants grown with the inorganic sources of P KH2PO4 and calcium tribasic phosphate and produced more dry matter when grown in soils, Plants grown with organic P compounds in both nutrient solutions and soil had higher P concentrations and contents than plants grown with inorganic P compounds. Phosphorus from organic sources was more readily available to plants than P from inorganic sources. Differences in growth and P use were noted among genotypes when a large number of plants (90 to 120 plants per container) were grown together in nutrient solution at 129 umole P liter-1. Widest differences among genotypes for dry matter yields were noted for plants grown with ethylammonium, glyceryl-, calcium tribasic-, and potassium dihydrogen phsophates. Plants grown with KH2PO4 and calcium tribasic phosphate had nearly six-fold higher values for dry matter produced per unit P than grown ethylammonium phosphate. Calcium tribasic phosphate and KH2PO4 appeared to be the best P compounds to use to screen sorghum genotypes for tolerance to low P (...) MenosSorghum (Sorghum bicolor (L.)
