Abstract/Contents: | In glasshouse experiments (a) elephant grass and (b) Kikuyu grass were given 0, 100 or 200 kg N/ha as NH4NO3 and nitrate reductase activity (NRa) investigated 19 and 22 days, respectively, after fertilizer application. NRa in (a) increased with increasing N rate, but decreased with increasing N rate in (b). The use of NRa in estimating N fertilizer requirement of crops is discussed. |
