Abstract :
A field experiment was carried out during Kharif season of 2010 and 2011 to study the effect of different nutrients treatments on the productivity of rice. Application of NPK with FYM and Zn proved to be superior in recording the highest Photosynthetic rate and Super Oxide Dismutase. Although fertilizers are important for enhancing rice production but excess use of fertilizer cause deterioration of soil quality which ultimately affect crop productivity so it is required to investigate the physiological aspects of rice plant under integrated nutrients. When imbalanced fertilizers doses are given to the rice-wheat cropping system, they showed a considerable decline in crop productivity and soil fertility.
