First published in 1989, Physiology of Crop Yield was thefirst student textbook to digest and assimilate the many advancesin crop physiology, within a framework of resource capture and use.Retaining the central core of the first edition, this long-awaitedsecond edition draws on recent developments in areas such asphenology, canopy dynamics and crop modelling, and the concepts ofsustainable crop production. A broad perspective is developed, fromthe gene through the plant and crop to the ecosystem,covering:



  • Advances in molecular biology relating to crop science
  • Limitation of crop yield by the supply of water ornitrogen
  • Global climate change and its impact on crop modelling
  • Physiological aspects of crop quality
  • A wider range of species, with emphasis on wheat, maize andsoybean


This book will be a valuable tool for advanced undergraduate andpostgraduate students of agricultural science, plant science,applied ecology and environmental science. It will be an essentialaddition to all libraries in universities and relevant researchestablishments.

Adobe ebog: Dette er Adobe DRM ebøger som downloades til din lokale computer eller mobil enhed.

 

For at læse bøgerne kræves særlig software, som understøtter denne type. Softwaren er gratis, men du bør sikre at du har rettigheder til installere software på den maskine du påtænker at anvende den på. Læs mere om Adobe DRM bøger

 

Levering: Et download link sendes pr email umiddelbart efter købet.
