This specially curated collection features four reviews of current
and key research on improving crop nutrient use efficiency. The
first chapter explores the relationship between rhizobacteria and
plant roots, looking primarily at the recruitment of rhizobacteria
by the plant to carry out particular functions, such as nutrient
acquisition. The chapter highlights our current understanding of
the molecular determinants of legume nodulation as well as
challenges for improvements of biological nitrogen fixation in
legumes and non-legumes. The second chapter considers the rising
use of nitrogen (N) fertilizer in agriculture and its role in the
shrinking contribution of soil organic N. The chapter explores the
impact of the inefficient management of N (low nitrogen-use
efficiency) and the consequent developments of major environmental
issues, such as pollution to groundwater, oceans and the
atmosphere. The third chapter addresses key issues in using N
fertilizers in wheat production, such as product cost and
environmental impact. The chapter summarises the development of
N-efficient cultivars and their economic benefits, as well as their
role in reducing the environmental impact of excessive N fertilizer
inputs, whilst maintaining respectable yields. The final chapter
considers the use of breeding techniques, including genetic
variability, to develop more efficient wheat varieties with
improved traits related to nitrogen capture, nitrogen assimilation
and nitrogen remobilization.
"These books present a comprehensive coverage of issues facing
wheat production globally. The authors represent the top scientists
involved in the diverse areas that are important for sustainable
wheat production and will this book provides an excellent resource
for those interested in wheat improvement and production." Dr
Hans-Joachim Braun, Director Global Wheat Program and CRP Wheat,
International Maize and Wheat Improvement Center (CIMMYT), Mexico
Wheat is the most widely cultivated cereal in the world and a
staple food for around 3 billion people. It has been estimated that
demand for wheat could increase by up to 60% by 2050. There is an
urgent need to increase yields in the face of such challenges as
climate change, threats from pests and diseases and the need to
make cultivation more resource-efficient and sustainable. Drawing
on an international range of expertise, this collection focuses on
ways of improving the cultivation of wheat at each step in the
value chain, from breeding to post-harvest storage. Volume 1
reviews research in wheat breeding and quality traits as well as
diseases and pests and their management. Chapters in Part 1 review
advances in understanding of wheat physiology and genetics and how
this has informed developments in breeding, including developing
varieties with desirable traits such as drought tolerance. Part 2
discusses aspects of nutritional and processing quality. Chapters
in Part 3 cover research on key wheat diseases and their control as
well as the management of insect pests and weeds. Achieving
sustainable cultivation of wheat Volume 1: Breeding, quality
traits, pests and diseases will be a standard reference for cereal
scientists in universities, government and other research centres
and companies involved in wheat cultivation. It is accompanied by
Volume 2 which reviews improvements in cultivation techniques.
