An experiment was conducted in greenhouse to study the effects of zinc and manganese fertilizers on maize growth and chlorophyllous contents. The application of zinc and manganese improved the growth of maize in water sufficient and drought condition. Under drought conditions, the maize height, dry shoot weight and dry root weight were increased 11.7%, 37.8% and 69.3% in zinc treatments, compared with no zinc treatments, respectively. While those increased in manganese treatments were 12.6%, 24.8% and 29.5%, compared with no manganese treatment. Under water sufficient conditions, the increase of above growth indexes were 10.7%, 11.1% and 30.3% in zinc treatments and 9.0%, 7.6% and 21.6% in manganese treatments. In water sufficient conditions, the application of zinc increased Chla, Chlb, and Chlt with 14.3%; 15.3% and 14.8% respectively. While those increased in manganese treatments were 31.7%; 40.0% and35.8% respectively. In drought conditions, the application of zinc increased Chla, Chlb, and Chlt with 8.9%; 10.23% and 9.5% respectively, and those in manganese treatments were 16.3%; 11.7% and 12.6% respectively.
