Nutrient recycling is now being considered as part of the concept of integrated nutrient management. The fertilizer potential of vermicompost is often attributed to its different concentrations and amounts of nutrients, especially nitrogen. Therefore, this dissertation work was taken at Bihar Agricultural University, Sabour to study the Effect of vermicompost application on nitrogen transformation in soil. So, two pot experiment has been taken: (1) Greenhouse study under the effect of root rhizosphere and (2) laboratory incubation study (without root rhizosphere ). Different levels of vermicompost were applied resulting different releasing pattern of mineralizable nitrogen, ammoniacal nitrogen, nitrate nitrogen and organic carbon due to the effect of root rhizosphere and activity of soil microbes in both the study.

Sugarcane is one of the most important cash crops grown in all tropical and subtropical countries of the world. Sugar factories generate many by-products (bagasse, molasses, press mud & waste materials). Molasses is used in distillery industry for the production of alcohol. Distilleries discharge waste water called as spent wash, which directly not used in agricultural fields because of its high biological oxygen demand (BOD) and chemical oxygen demand (COD). The spent wash contains 30-35% C; 2.31% N; 0.82% P and 9.25% K. There was a remarkable reduction in BOD, COD and salinity after bio-methanization process using methane gas and utilizing methogenic bacteria. The manurial value of the effluents can profitably be used as supplement to fertilizer and organic matter.

Interferon Regulatory Factor-2 is a vertebrate transcription factor having oncogenic nature; it antagonises Interferon Regulatory Factor-1, a tumor suppressor gene, functions. Knockout mice for IRF-2 gene showed defect in B-cell lymphopoeisis, they died following LCMV (Lymphocytic Choriomeningitis Virus) infections. IRF-2 is functionally just opposite of IRF-1. Interestingly, one would have thought that as IRF-1-/- (knock-out) mice showed lack of CD8+T cells and low cytotoxicity of NK cells, the over production of IRF-2 in mice may restore it. But it does not happen so, the reason being unknown. However, IRF-2 binds at Interferon Stimulated Response Element sequence in viral infected cell. This book is about mouse IRF-2 gene cDNA cloning and expression of chimeric protein in E.coli. This study will serve as a platform for further functional analysis of chimeric IRF-2, which is potent oncogene in aberrant conditions.

The brief is the first to focus exclusively on environmentally friendly delivery of pesticides (controlled-release nanoparticulate formulation of pesticides using biodegradable polymers as carriers).
