The present study was conducted at the Dr. N.E. Borlaug's Crop
Research Centre, G.B. Pant University of Agriculture and
Technology, Pantnagar, Uttarakhand, India with an objective to
evaluate the effects of different N doses on growth dynamic,
morphological, physiological parameters and nitrogen use efficiency
in five genotypes of rice. The field experiment was conducted
during rainy season of 2008 and 2009. Five rice genotypes (KRH-2-
hybrid, Vasumati- aromatic, Tulsi, Kasturi and Krishna Hamsa- high
yielding) were used as experimental material. The N fertilizer 0,
50, 100 and 200N kg ha-1 was sprouted in the field. The growth
parameters were recorded at time of panicle initiation, maximum
tillering and reproductive stage. The growth as well as
physiological parameters and guttative fluid increases as the
nitrogen levels increased. The grain and biological yieldalso
increased with increasing nitrogen levels. The application of
nitrogen fertilizers also affected the nitrogen and protein content
of leaves, seeds and the soil significantly. The NUE increased up
to N100 level and found to be highest for KRH-2.
