This book presents a holistic view of the complex and dynamic responses of plants to nanoparticles, the signal transduction mechanisms involved, and the regulation of gene expression. Further, it addresses the phytosynthesis of nanoparticles, the role of nanoparticles in the antioxidant systems of plants and agriculture, the beneficial and harmful effects of nanoparticles on plants, and the application of nanoparticles and nanotubes to mass spectrometry, aiming ultimately at an analysis of the metabolomics of plants.

Plant nutrient is certainly a boon for plant growth and development. Among the nutrients, nitrogen, phosphorus, sulphur and potassium are key nutrients and improve crop productivity by enhancing growth and physiological function of plant. However, it is necessary not to further improve the productivity of rapeseed-mustard and to maintain the crop quality and soil fertility lost due to excess fertilization. The present monograph deals with the origin distribution and different uses of rapeseed-mustard.
