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...

The present endeavor embodies studies pertaining to the development of nitrogen containing fused ring systems as potential central nervous system active agents. The thesis has been organized into three sections, each section includes five chapters. The studies cover all the aspects of medicinal chemistry research, starting from synthetic organic chemistry to biological activity and eventually the molecular docking of active compounds. Few privileged scaffolds have been identified for the current study. One of them is 3-benzazepine, a seven membered bicyclic benzoannelated fused ring system....
