Peanut is an important crop in the semi-arid regions of the world. Both, irrigation and well water can provide the water necessary for it. It is a nutritious seed nut crop and has manyfold uses. As such, research on this crop is imperative. This book reviews physiological aspects, keeping in mind the changing agroclimatic conditions. Growth, development and yield are described on the basis of cellular and morphological manifestations. Being a C3 plant, the photosynthesis and respiration in peanuts is critically viewed specially under varying environment conditions and genotypes. The study of nitrogen assimilation and biological nitrogen fixation have been presented in light of the prevalent environmental and gene effects. The role of plant growth regulators in peanuts is elaborated on, stating up-to-date mode of actions. Special emphasis has been given to mechanisms of abiotic stress effects. The chapters (13) are arranged on the basis of physiology, cellular structure, biochemistry, molecular and genomics concepts.

The book provides in-depth knowledge on the physiology of soybean. It is written lucidly, systematically, and in depth. The book provides recent information and findings, explained with illustrations to express the ideas and concepts vividly to university students and researchers, and provides a better understanding of the improvement of the productivity of soybean to cope with the future demand. It describes the physiology of growth, development, flowering, pod development and seed yield as well as C, O, N and Oil metabolisms – their hormonal regulations under normal and stress environmental conditions. Molecular approaches are also described.

Rice is the staple food for more than half of the world's population, yet cold temperatures during the cropping period cause a significant loss of yield. To cope with the world's increasing population, it is necessary to develop high yielding rice varieties that are tolerant to abiotic stress conditions, such as drought, salinity, and cold. This book provides a clear understanding of cold stress in rice in the hopes that it will provide insight to the subject for further research so that rice plants may be grown efficiently in cold regions with high productivity.

The book analyses different aspects viz. morphology, physiology, biochemistry, and genetics and reviews the suitability of different varieties for better sustainability and reduction of yield loss. It also reviews the different types of floods, and studies biological changes in indigenous and the recently developed rice varieties.
