Description In a greenhouse experiment, influx isotherms were obtained for nitrate and ammonium from pigeonpeas cv. ICPL 87, chickpea cv. K850, groundnut cv. NCAC 17090, sorghum cv. CSH5, Pennisetum glaucum cv. WC 75 and maize cv. Ganga 5. The transition in influx isotherms for both N sources was within the concentration range (0.05-2.5 mM) tested. There were significant differences in Km and Vmax for ammonium between legumes and cereals. The difference in the kinetic properties for nitrate uptake between the 2 groups of plants only became apparent at the highest concentration tested. Legumes translocated absorbed nitrate and ammonium to shoots more rapidly than cereals
