Abstract

Lime rates based on the base saturation of the soil were studied for perennial soybean (Neonotonia wightiicv. Tinaroo) and galactia (Galactia striata cv. Yarana) grown in pots a greenhouse conditions, in order to maximize forage yield, nodulation, and total nitrogen in the plants. Liming was applied to reach 23; 30; 56 and 65% base saturation through the application of CaO alnd MgO. A randomized complete block design was used with four replications. Perennial soybean at the second harvest and galactia in the two harvest showed linear increase in forage yield and in the total of nitrogen in the plants as lime rates increased. Plant top calcium and magnesium concentrations increased in both forage legumes as the soil base saturation increased. Zinc and manganese deficiency may occur in the two legumes when soil base saturation reach values as high as 50%.
