520			_aA study was conducted onfarm in Yala division, Siaya district, in 1996 and 1997 to determine the critical starter inorganic nitrogen rate for increased maize productivity under Striga hermonthica infestation. Starter N treatments were laid out in randomized complete blocks with three replicates per site. Results indicate that inorganic N applied at planting significantly (P<0.05) increased maize grain yields at one and three sites in 1996 and 1997 respectively. Application of 20 kg N/ha at planting increased maize grain yield by 2.4 t/ha at Marenyo in 1996 and by 2.5, 2.1 and 1.3 t/ha at Ulumbi, Jina and Lihanda respectively in 1997 compared to the unfertilized treatment. Increasing starter N rate to 40 kg/ha consistently gave higher grain yields than the unfertilized treatment at all sites during both seasons. Delaying N until 30 days after emergence (DAE) reduced maize grain yields at two sites in 1997 only. Applying N at planting or 30 DAE did not suppress Striga infestation during both seasons, However, the results of this study show that 40 kg/ha is the critical starter inorganic N rate required for increased and economic maize production in the Striga hermonthica infested areas of western kenya.
