DESCRIPTION OF COURSES
AP 630 CROP MICROMETEOROLOGY (2L+1P) II
(Pre-requisite AP 530)
To impart advanced theoretical and practical knowledge about the physical processes in the atmosphere near the ground for growing crop plants.
Micro-, meso- and macro-climates and their importance, Atmosphere near the ground – bare soil and crop surfaces, exchange of mass, momentum and energy between surface and overlaying atmosphere, exchange coefficients, Richardson number & Reynold’s analogy, Boundary layer, frictional affects, eddy diffusion, forced & free convection.
Micrometeorological parameters; instruments and measuring techniques, agromet observatory.
Radiation, temperature, wind, humidity and carbon dioxide profiles in crops, radiation interception and utilization by crops – albedo, net radiation, PAR, LAI, biomass; photoperiodism, carbon dioxide and photosynthesis; net photosynthesis.
Air, canopy and leaf temperatures and their biological effects – cardinal temperatures, thermal time, growing degree days, heat use efficiency and their application in field crops.
Wind profile near the ground; roughness and zero plane displacement, evapotranspiration –potential and actual; advection.
Modification of microclimate by cultural practices, protection of crops from extreme weather.
Crop yield and weather parameters; climatic normal of crop plants, crop weather calendars, crop growth models, use of remote sensing for crop growth and yields estimation. Weather based insect pest and disease forecasting, Weather based agro-advisory.
IPAR, FAPAR, PAR Extinction Coefficient, RUE, Temperate profile, Wind profile, humidity, Net Radiation profile of the crops at different stages. Thermal indices, albedo, canopy temperature, CATD, SDD and CWSI.
