Water stagnation and submergence is a major factor in rice growing as rice requires substantial water and is grown in paddy fields with adequate water. Water stagnation and submergence happens due to excessive rainfall or flash floods caused by release of water from upstream dams. The duration of submergence can last several weeks, and the level of water may be as high as 100 cm. This impacts rice yields.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. There are seven chapters viz. Introduction, History of floods, Diversity of submergence, Adoptive morphology, Physiological aspects, Molecular and genetic aspects and Yield and yield-gaps. It is comprehensive with scientific dogma, findings and reasonings for students at universities and researchers.

Nitrogen is an essential primary nutrient for plant growth and development. With the demand for high growth and yield of plants and the depletion of organics in soil, nitrogen availability in soil has become insufficient. This simple and comprehensive book covers the important and current information regarding rice plant biology and nitrogen metabolism. The book is divided into ten chapters that feature the steps of nitrogen assimilation and utilization in rice plant systems. Apart from describing the steps and pathways of nitrogen metabolism in rice, the book also emphasis the changes taking place due to genotypes and environmental factors and stressors during rice growth and development.
