This book aims at bringing out comprehensive information on cropping systems modelling in the world. The major focus of this book is to address the integration of soil, plant and environmental interactions for climate smart agriculture. This book covers aspects of application of Decision Support System for Agrotechnology Transfer (DSSAT) for climate smart agriculture. Step-by-step details of application of modelling approaches used for various cropping systems under changing climate are provided which are being adopted by farmers in the world. The book is enriched with figures or diagrams to show the various mechanisms involved to support the decision making for climate change adaptations. Essential information is given regarding crop models calibration, evaluation and application and every individual chapter is comprised of a specific cropping system. Further contents include integration of climate models and crop models for refining the decisions for sustaining the production of various cropping systems for climate smart agriculture. This book assists the agricultural scientists involved in research regarding climate smart agriculture for improving the standards of agricultural research for ensuring food security under changing climate. This is also equally useful for policy makers being involved in future planning.

A range of DLC, Si-DLC, N-DLC and F-DLC films were prepared using ¿PECVD ¿with various film thicknesses (100-200) nm. The simplest amino acid ¿¿¿Glycine¿ is used as a model biological compound to ¿investigate surface adsorption ¿phenomena. Following exposure to solutions ¿containing glycine, surface characteristic has been ¿investigated by various techniques. XPS analysis showed the appearance of a new ¿peak at 400 eV ¿¿(N1s) and a change in the intensity of the C1s and O1s peaks. Both ¿Raman and ¿FTIR spectra showed bands related to functional groups ¿of glycine. ¿AFM analysis showed a change in surface roughness of the films with ¿the ratio of ¿rms values increasing following exposure to glycine. Changes in the ¿surface energy of the films were observed following ¿exposure to glycine with an ¿increase in the surface tension. Based on the kinetic study, the adsorption ¿process ¿obeyed the pseudo first order rate of reaction, and both ¿G and ¿H results showed that the ¿adsorption is ¿spontaneous and exothermic. The ¿Freundlich-Langmuir isotherm ¿suggest that the attachment of glycine is non-¿uniform and multilayer. ¿
