This monograph deals with the use of wireless sensor network (WSN) and its application in precision farming (PF). The subject is introduced by reviewing the global and Indian agricultural systems in general and identifies a niche for deployment of ICT (Information and Communication Technologies) through WSN. A case study built through a 2 year research project on deployment of WSN in green house at pilot scale and at grapevine in NASHIK district (India) has enabled testing its robustness and permitting to evaluate the input requirement i.e. water requirement and need of pesticides. The monograph delineates the WSN components (hardware and software) and demonstrates the infection index prediction through tabulated and graphical results. Also the technical and social challenges of precision farming systems in India using WSN have been discussed. This Monograph will be useful for both practitioners of precision farming as well as academicians engaged in conducting applied research in the area of WSN and ICT in agriculture.

This monograph deals with use of Infrared (IR) energy for parboiling of paddy, a process which has long been established as an excellent means of improving the milling quality of paddy. IR heating has appeared as one of the potential addition to the traditional parboiling method because of its several advantages: simplicity of the equipment, fast transient response and significant energy saving etc. It is attractive only for surface heating application; with increased bed depth, vibration provides a means of utilizing high intensities of infrared energy without any visible damage to the product. Vibration aided IR heating of high moisture paddy has been investigated to develop a faster and more efficient drying-cum- parboiling system for the grain industry. This monograph delineates the design and development of equipment capable of modulating frequency and amplitude of vibration, detailed analysis of drying behavior and quality evaluation of IR irradiated paddy followed by optimization. This Monograph will be useful for industry practitioners and academicians engaged in conducting research in the area of drying of food grains using infrared energy.
