| Abstract: |
| This study aims to elucidate the response to fertilization of soybean cultivars, which were released in different years in Heilongjiang province, such as Hefeng 25, Suinong 14, Hefeng 39, Kenfeng 16, and Hefeng 35, by investigating agronomical traits and yield component. The results showed that yield per plant, main stem nodes, number of pods per plant and photosynthetic rate improved significantly, and plant height, main stem nodes, grain per plant and leaf area per plant as well. The leaf area per plant was the suitable index. Improvement in agronomical traits and yield component under low fertilization was mainly due to the increase in number of pods per plant, and that under medium fertilization due to the increase in photosynthetic rate, under high fertilization due to the increase in photosynthetic rate and main stem node number. |
