Effect of Different Levels of Zinc and Phosphorus on Seedling Growth, Chlorophyll and Peroxidase Contents of Rice

S.M. Alam, M. A. Khan, M. Ali and R. Ansari    

Abstract: Water culture experiment was conducted to observe the effects of different levels of Zn and P alone and in combination on the growth ,chlorophyll and peroxidase contents of rice (cv. Shadab).The concentrations for the study were Zn: 0.0, 5.0, 10.0, and 20.0 mg L-11, and P 0.0, 20.0, 40.0, 60.0 mg L -1. It was observed that the growth of fresh and dry weights of shoot, root and its length were increased in more or less all the treatments as compared to control. Contrary to this the chlorophyll and peroxidase contents were substantially decreased with increasing levels of Zn and P. It was observed that intermediate levels of both Zn and P were seemed to be beneficial for the growth of rice.
