| Abstract: |
| An experiment was conducted in greenhouse to study the effects of manganese fertilizer on growth and photosynthetic pigments of maize. The application of manganese improved the growth of maize in both sufficient water and drought conditions. Under drought conditions, the maize height, dry shoot weight and dry root weight in manganese treatments were increased by 12.6%, 24.8% and 29.5% respectively, compared with no manganese treatments. Under sufficient water conditions, these indexes in manganese treatments were increased by 9.0%, 7.6% and 21.6% respectively. The contents of Chla, Chlb and Chlt were increased by 31.7% and 16.3%, 40.0% and 11.7%, 35.8% and 12.6% under sufficient water and drought condition respectively. |
