    Abstract


    The effect granular or slow-release nitrogen fertilizer ongrowth, development and yield of C919 hybrid maize was studied in Winter 2011 and Spring 2012, in Vinh Loc district, Thanh Hoa province. The experiment consistedof seven application levels per hectare (T1: 0kgN; T 2: 90kgN; T 3: 120kgN; T 4: 150kgN; T 5: 180kgN; T 6: 210kgN and T 7: 150kgN). The experiment was arranged in a randomized complete block design (RCBD) with three replications, 14 m2plot size, and planting density of 59,000/ha. The experiment plots were applied with 8 tons of manure, 90 P2O5and 90 K2O/ha. The study results showed that the use of slow-release nitrogen fertilizer exerted positive effect on growth, development and yield of corn. With application levels from 120kgN to 210 kgN/ha corn yields varried from 7.046 ton/ha to 7.813 ton/ha; higher than ureaapplicationfrom 16.9 - 21.7%. Application of slow-release nitrogen fertilizer increased nitrogen use efficiency (NUE) as compared withurea. It was suggested that forcultivation of C919maize in the study area,slow-release nitrogen fertilizer be applied with the rate of 120 kgN/ha plus the 8 tons of manure, 90kg P2O5and 90kg K2O.
