Book Description
Corn and grain sorghum (Sorghum bicolor subsp. bicolor L) are among the top cereal crops world wide, and both are key for global food security. Similarities between the two crops, particularly their adaptation for warm-season grain production, pose an opportunity for comparisons to inform appropriate cropping decisions. This book provides a comprehensive review of the similarities and differences between corn and grain sorghum. It compares corn and sorghum crops in areas such as morphology, physiology, phenology, yield, resource use and efficiency, and impact of both crops in different cropping systems. Producers, researchers and extension agents in search of reliable scientific information will find this in-depth comparison of crops with potential fit in dryland and irrigations cropping systems particularly valuable. - Presents a wide range of points of comparison - Offers important insights for crop decision making

Book Description
Crop Physiology: Case Histories of Major Crops updates the physiology of broad-acre crops with a focus on the genetic, environmental and management drivers of development, capture and efficiency in the use of radiation, water and nutrients, the formation of yield and aspects of quality. These physiological process are presented in a double context of challenges and solutions. The challenges to increase plant-based food, fodder, fiber and energy against the backdrop of population increase, climate change, dietary choices and declining public funding for research and development in agriculture are unprecedented and urgent. The proximal technological solutions to these challenges are genetic improvement and agronomy. Hence, the premise of the book is that crop physiology is most valuable when it engages meaningfully with breeding and agronomy. With contributions from 92 leading scientists from around the world, each chapter deals with a crop: maize, rice, wheat, barley, sorghum and oat; quinoa; soybean, field pea, chickpea, peanut, common bean, lentil, lupin and faba bean; sunflower and canola; potato, cassava, sugar beet and sugarcane; and cotton. A crop-based approach to crop physiology in a G x E x M context Captures the perspectives of global experts on 22 crops

Book Description
This book discusses and addresses the rapidly increasing world population demand for food, which is expected to double by 2050. To meet these demands farmers will need to improve crop productivity, which relies heavily on nitrogen (N) fertilization. Production of N fertilizers, however, consumes huge amounts of energy and the loss of excess N fertilizers to leaching results in the pollution of waterways and oceans. Therefore, increasing plant nitrogen use efficiency (NUE) is essential to help farmers produce more while conserving the environment. This book assembles some of the best work of top researchers from academic and industrial institutions in the area of NUE and provides valuable insight to scholars and researchers by its comprehensive discussion of current and future strategies to improve NUE through genetic manipulation. This book should also be highly valuable to policy makers, environmentalists, farmers, biotechnology executives, and to the hard-core researchers working in the lab.

Book Description
Understanding physiological changes in response to long-term selection for yield can inform breeding decisions and hasten genetic gain. This dissertation is organized into four chapters: Chapter 1, Introduction, Chapter 2, presents yield gain achieved for US sorghum hybrids and their components (grain number and grain weight), Chapter 3 focuses on nutrient use efficiency, specifically on nitrogen (N) internal efficiency (NIE, yield to N uptake ratio), and Chapter 4, Conclusions. For Chapters 2 and 3, field trials were conducted during the 2018 and 2019 seasons in eight site-years across the states of Kansas and Texas (US) including 20 commercially available grain sorghum hybrids released by Pioneer between 1963 and 2017. Consistent with estimates using historical yield data, sorghum yield improvement was 27 kg ha−1 yr−1. Grain number increased at a rate of 100 grains m−2 yr−1, and modern hybrids had larger panicle size with greater accumulation of WSC during the vegetative period (until flowering). Additionally, greater remobilization of WSC during the reproductive period (after flowering) to grain was captured, thus, maintaining grain size on the increased grain number per unit area and harvest index (Chapter 2). The N internal efficiency (NIE, yield to N uptake ratio) increased at the expense of a reduction in grain N concentration and, in minor proportion, due to an increase in the N harvest index (NHI) at maturity for newer relative to older hybrids. Newer genotypes evidenced greater N remobilization from the stover to the grains during the reproductive period (Chapter 3). This study demonstrates the physiological foundations for yield enhancement and the N and C utilization behind yield genetic gain for sorghum hybrids. Future yield gains in sorghum can be pursued by enhancing N uptake to sustain further genetic progress.

Book Description
Nutrient Use Efficiency in Plants: Concepts and Approaches is the ninth volume in the Plant Ecophysiology series. It presents a broad overview of topics related to improvement of nutrient use efficiency of crops. Nutrient use efficiency (NUE) is a measure of how well plants use the available mineral nutrients. It can be defined as yield (biomass) per unit input (fertilizer, nutrient content). NUE is a complex trait: it depends on the ability to take up the nutrients from the soil, but also on transport, storage, mobilization, usage within the plant, and even on the environment. NUE is of particular interest as a major target for crop improvement. Improvement of NUE is an essential pre-requisite for expansion of crop production into marginal lands with low nutrient availability but also a way to reduce use of inorganic fertilizer.
