Summary: An experiment on synchronizing of nitrogen requirement in the maize/millet relay cropping system was carried out in the Hill Crops Research Program (HCRP}, Kabre during the summer season of 1999/2000 -2000/2001 to identify the optimum time of nitrogen application for higher maize grain production in mid hill conditions. The chemical fertilizers were applied in all treatments at the rate of 60:30:30 kg NPK/ha. All phosphorus and potash was applied as a basal dose and nitrogen application was split as per treatments. Eight treatments were allocated in four replications in RCB design with plot size 6 m2 (4 rows of 2 meter long). The highest grain yield (5,614/kg/ha) was produced from the treatment provided with 50% nitrogen for basal and 50% at knee-high stage followed by (5,475 kg/ ha) treatment applied with 100% nitrogen at knee-high stage. The lowest grain yield 3,785 kg/ha) was produced by the treatment that provided all nitrogen as a basal dose. However, the highest finger millet grain yield (735 kg/ha) was produced from the treatment provided with 50% nitrogen for basal dose + 50% N at tasseling stage followed by (655 kg/ha) with 1/3N knee-high stage + 1/3N tasseling + 1/3N millet transplanting stage. The lowest yield (535 kg/ ha) was produced by the treatment that provided all nitrogen as a basal dose.
