Book Description
Information available for other cereals and the limited or circumstantial evidence available for rice indicate that we can now breed varieties that have improved yield under drought and produce high yields in the good seasons. This manual aims to help plant breeders develop such varieties.

Book Description
In this manual, we provide detailed protocols for screening rice under the major stresses affecting both rainfed and irrigated rice: submergence, salinity, drought, and the soil problems – excess iron and aluminum. We also include protocols for a new area of abiotic stress research since it is increasingly occurring in farmers’ field due to climate change: combined stresses. Results from these protocols on combined drought + salinity and submergence + salinity indicate that the effects on the rice plant are sometimes different than under individual stresses. The protocols in this manual have been developed and optimized over decades at IRRI. Numerous scientists, technical staff and students have been involved in the development and use of these protocols, and it is often their experiences that have led to improvements, all of which are highly acknowledged. Our objective with this compilation is to provide a resource for researchers around the globe who aim to improve the abiotic stress tolerance of rice as part of the effort to benefit rice farmers in both rainfed and irrigated areas affected by abiotic stresses

Book Description
Explore an in-depth and insightful collection of resources discussing various aspects of root structure and function in intensive agricultural systems The Root Systems in Sustainable Agricultural Intensification delivers a comprehensive treatment of state-of-the-art concepts in the theoretical and practical aspects of agricultural management to enhance root system architecture and function. The book emphasizes the agricultural measures that enhance root capacity to develop and function under a range of water and nutrient regimes to maximize food, feed, and fibre production, as well as minimize undesirable water and nutrient losses to the environment. This reference includes resources that discuss a variety of soil, plant, agronomy, farming system, breeding, molecular and modelling aspects to the subject. It also discusses strategies and mechanisms that underpin increased water- and nutrient-use efficiency and combines consideration of natural and agricultural systems to show the continuity of traits and mechanisms. Finally, the book explores issues related to the global economy as well as widespread social issues that arise from, or are underpinned by, agricultural intensification. Readers will also benefit from the inclusion of: A thorough introduction to sustainable intensification, including its meaning, the need for the technology, components, and the role of root systems Exploration of the dynamics of root systems in crop and pasture genotypes over the last 100 years Discussion of the interplay between root structure and function with soil microbiome in enhancing efficiency of nitrogen and phosphorus acquisition Evaluation of water uptake in drying soil, including balancing supply and demand Perfect for agronomists, horticulturalists, plant and soil scientists, breeders, and soil microbiologists, The Root Systems in Sustainable Agricultural Intensification will also earn a place in the libraries of advanced undergraduate and postgraduate students in this field who seek a one-stop reference in the area of root structure and function.
