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
Sorghum is among the top five cereals and one of the key crops in global food security efforts. Sorghum is a resilient crop under high-stress environments, ensuring productivity and access to food when other crops fail. Scientists see the potential of sorghum as a main staple food in a future challenged by climate change. The contributors provide a comprehensive review of sorghum knowledge. The discussion covers genetic improvements, development of new hybrids, biotechnology, and physiological modifications. Production topics include water and nutrient management, rotations, and pest control. Final end uses, sorghum as a bioenergy crop, markets, and the future of sorghum are presented. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.

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.
