Abstract

The effect of nursery manuring in rice was studied at Tamil Nadu Rice Research Institute, Aduthurai during 1985-1987. Two forms of fertilizers, diammonium phosphate (DAP) and urea plus super phosphate with different levels and time of application were compared. It was inferred that root and shoot length of rice seedlings were significantly influenced by the application of either DAP or urea plus super phosphate. Shoot length of seedlings was significantly increased by applying the fertilizer 10 days after sowing compared to basal application. Increased shoot length with lesser root length eased the pulling out operation with lesser per cent of seedling damage. Grain yield was not influenced by nursery manuring.
