About the book
This monograph provides a platform for agricultural scientists, researchers, vegetable growers and professional entrepreneurs to understand the fundamentals of greenhouse technology applicable to vegetable production, crop drying, poultry farming and space heating etc. Beginning with a historical background, it provides design, construction, instrumentation and error analysis in greenhouses and discusses the basics of solar energy, solar fraction and heat transfer. The different heating/ cooling concepts used to create favourable environment conditions inside greenhouses have been widely covered. Information on constituents of inside environment, root media, various crop production, thermal modeling, energy analysis and economic aspects of greenhouse technology have also been dealt with.
Large number of figures and tables • Solved exercises • Additional problems at the end of each chapter
