A single factor field experiment was lay out in Randomized Block Design (RCB) with of 13 treatments, repeated 3 times to study the effects of 5 doses apply of nitrogen (0
50
75
100
125 kg N ha-1 per harvest time) based on apply of 10 tones FYM + 100 P2O5 + 80 K2O
of 5 doses apply of phosphorus (0, 40, 60, 80, 100 kg P2O5 ha-1 per harvest time) based on apply of 10 tones FYM + 125 N + 80 K2O and of 5 doses apply of potassium (0, 35, 50, 65, 80 kg K2O ha-1 per harvest time) based on apply of 10 tones FYM + 125 N + 100 P2O5 on growth, development, medicinal yield, glycoalcaloid content of Solanum hainanense Hance planting on the hill soil in Ngoc Lac district, Thanh Hoa provice. The experiment was repeated in two harvest times in year 2017 -2018. The results showed that: nitrogen has increased the medicinal yield and glycoalcaloid content at the dose of 50 - 100 N. Both of phosphorus and potassium tended to increase glycoalcaloid content when increasing the dose of P2O5 and K2O, ofwhich dose apply of 40 - 60 P2O5 and dose apply of 35 - 50 K2O was highest in glycoalcaloid content. Based on of establishing the correlation regression between the doses apply of N, P2O5, K2O with medicinal yield and glycoalcaloid yield, the dose apply of maximum on technical was determined at 107.3 N
82.2 P2O5
68.2 K2O for medicinal yield and 100.8 N
77.6 P2O5
63.5 K2O for glycoalcaloid yield. The dose apply of optimization on economic was determined at the level of 101.4 N
95 P2O5
76.9 K2O for medicinal yield and 96.3 N
92.0 P2O5
74.4 K2O for glucoalcaloid yield.Bố trí thí nghiệm đồng ruộng một nhân tố, 13 công thức, nghiên cứu ảnh hưởng của 5 lượng bón đạm (0, 50, 75,100, 125 N/ha/lứa thu hoạch) trên nền bón 10 tấn phân chuồng + 100 P2O5 + 80 K2O
