Book Description
Several morpho physiological traits are traditionally used as screening criteria for drought tolerance such as relative water content (RWC), stomatal index, water use efficiency (WUE) etc. Crop WUE can be improved by optimizing crop transpiration. Several workers have proposed carbon isotope discrimination (CID), ash content and canopy temperature depression (CTD) as selection criteria for transpiration efficiency (TE), which may serve as the surrogate measures for improvement in grain yield.To identify suitable physiological traits useful in wheat breeding under water stress environment is the major thrust area of present investigation. For this, Durum and aestivum genotypes were selected from the breeding material of ARI, Pune (MS, India).Experimental trials on Triticum durum were conducted under three different water regimes viz. residual soil moisture stress (RSMS), post anthesis water stress (PAWS) as limited irrigation (LI) and well watered (WW) conditions.Data were collected for agronomical and physiological characters. Soil water balance model 'BUDGET' (Raes et.al. 2006) has been used for deriving WUE using meteorological, rainfall and irrigation data of (2004-05)and(2006)

Book Description
Agricultural, botanical, and social scientists from the four quarters of the world address the impact of climate change on crop productivity, some approaches to adapt plants to both biotic and abiotic stresses, and measures to reduce greenhouse gases. They cover predictions of climate change within the context of agriculture, adapting to biotic and abiotic stresses through crop breeding, sustainable and resource-conserving technologies for adapting to and mitigating climate change, and new tools for enhancing crop adaptation to climate change. Specific topics include economic impacts of climate change on agriculture to 2030, breeding for adaptation to heat and drought stress, managing resident soil microbial community structure and function to suppress the development of soil-borne diseases, and applying geographical information systems (GIS) and crop simulation modeling in climate change research.

Book Description
Wheat (Triticum aestivum L.) is the most important cereal crop for global food supply. Most of the wheat crop in developing countries including Nepal is either grown rainfed condition or under limited irrigation condition, thus water stress hits the wheat crop at different growth stages which thus limiting the grain yield. An experiment with 60 different genotypes of wheat was carried out in Nepal for the characterization for drought adaptation.The ANOVA (Analysis of Variance) revealed significant variation between environments and among the wheat germplasms for most of the drought adaptive traits. A wide range of variability was observed for the selected drougt adaptive morpho-physiological traits in moisture stressed and non-stressed environments. WUE was highly significantly correlated with biomass production. Nepalese cultivar Gautam showed a number of favorable drought adaptive traits. A number of landraces and advanced breeding lines showed high level of water use efficiency and other positive traits for drought adaptation.

Book Description
This single volume explores the theoretical and the practical aspects of crop physiological processes around the world The marked decrease over the past century in the land available for crop production has brought about mounting pressure to increase crop yields, especially in developing nations. Physiology of Crop Production provides cutting-edge research and data for complete coverage of the physiology of crop production, all in one source, right at your fingertips. This valuable reference gives the extensive in-depth information soil and crop professionals need to maximize crop productivity anywhere the world. Leading soil and plant scientists and researchers clearly explain theory, practical applications, and the latest advances in the field. Crop physiology is a vital science needed to understand crop growth and development to facilitate increases of plant yield. Physiology of Crop Production presents a wide range of information and references from varying regions of the world to make the book as complete and broadly focused as possible. Discussion in each chapter is supported by experimental data to make this book a superb resource that will be used again and again. Chapter topics include plant and root architecture, growth and yield components, photosynthesis, source-sink relationship, water use efficiency, crop yield relative to water stress, and active and passive ion transport. Several figures and tables accompany the extensive referencing to provide a detailed, in-depth look at every facet of crop production. Physiology of Crop Production explores management strategies for: ideal plant architecture maximizing root systems ideal yield components maximizing photosynthesis maximizing source-sink relationship sequestration of carbon dioxide reducing the effects of drought improving N, P, K, Ca, Mg, and S nutrition improving micronutrient uptake Physiology of Crop Production is an essential desktop resource for plant physiologists, soil and crop scientists, breeders, agronomists, agronomy administrators in agro-industry, educators, and upper-level undergraduate and graduate students.

Book Description
The root is the organ that functions as the interface between the plant and the earth environment. Many human management practices involving crops, forests and natural vegetation also affect plant growth through the soil and roots. Understanding the morphology and function of roots from the cellular level to the level of the whole root system is required for both plant production and environmental protection. This book is at the forefront of plant root science (rhizology), catering to professional plant scientists and graduate students. It covers root development, stress physiology, ecology, and associations with microorganisms. The chapters are selected papers originally presented at the 6th Symposium of the International Society of Root Research, where plant biologists, ecologists, soil microbiologists, crop scientists, forestry scientists, and environmental scientists, among others, gathered to discuss current research results and to establish rhizology as a newly integrated research area.
