Crop Weather Interactions (Paper Code: 17010708)

Weather and its importance in agriculture; radiation spectrum, radiation laws for incoming and outgoing radiations, optical characteristics, solar radiation distribution in crop canopies, radiation and energy balance component and radiation use efficiency

Temperature concepts in agriculture: cardinal temperature, thermal indices, heat unit/growing degree day, photothermal unit, heliothermal unit, Vant Hoff law/Q10 and their merits and demerits; temperature and humidity profile

Concept of actual, potential and reference evapotranspiration, lysimeter, empirical methods of ET estimation and antitranspirants; climatological approach in irrigation scheduling; crop micro climate and its modifications: heat evading, heat trapping, mulches, wind break and shelterbelts

Wind concept in crops: wind profile for dwarf and tall crops; soil temperature concept in crops; concept of climate change; weather hazards: frost, fog, hail storm
