A new hybrid of maize (Pacific 999 Super) was investigated under six treatments; organic fertilizer (OF), chemical and granular organic fertilizer with hormone mixed formula A (HO-A), formula B (HO-B), formula C (HO-C), NPK-15-15-15 and control in 2017 and 2018 seasons at Phitsanulok, Thailand. The treatments were arranged in randomized complete block design (RCBD) with 3 replications. Fertilizer application rate was 300 kg/ha. Initial soil analysis had shown lower rates of NPK (0.394%, 0.013% and 0.191%). The vegetative growth data showed that, mean plant height, leaf area, leaf chlorophyll and total dry matter/plant were highest in HO-C (255.49 cm, 158.37 dm2, 61.10 and 299.62g, respectively). A maximum grain weight (9, 289.67 kg/ha), crude protein (8.99%) and profit (889.6 $/ha) were again recorded in HO-C. The results have demonstrated that the HO-C produced the greatest yield, income and is recommend for maize production.
