The experiment was carried out in the spring crop of 2014 in Gia Sang Ward, Thai Nguyen city with 6 treatments including treatment 1 (110N + 50P2O5 + 60K2O/ha), treatment 2 (120N + 60P2O5 + 70K2O/ha), treatment 3 (130N + 70P2O5 + 80K2O/ha), treatment 4 (140N + 80P2O5 + 90K2O/ha), treatment 5 (150N + 90P2O5 + 100K2O/ha), treatment 6 (160N + 100P2O5 + 110K2O/ha) and 3 tons micro-bio compose on each treatment. The experimental results showed that the different fertilizer rates did not much affect on growing duration and morphological characteristics of sticky hybrid maize HN88
pest tolerant ability tended to decrease with the increase of fertilizer
the fresh yield was ftom 70.8 to 92.1 quintal/ha. The highest ftesh yield and dry grain yield were in treatment 4 (140N + 80P2O5 + 90K2O/ha) with values 92.1 and 37.8 quintal/ha, respectively
economic efficiency was highest in the treatment 4
treatment 5 and 6 showed the best tasting quality.
