DESCRIPTION OF COURSES
WST 503 SOIL WATER PLANT ENVIRONMENT SYSTEM (2L+1P) I
To enable the students to study the interactive relationship among soil, water, plant and the environment in relation to the movement of water into soil, its intake by the plants and its release in the environment.
Introduction to Soil-Water-Plant-Environment System, Soil characteristics in relation to profile and soil horizon, soil system and basic properties of soil water potential, its various components and method of their measurements.
Movement of water in soils and its measurement, soil characteristics and properties in relation to irrigation, Plant water relations and role of water in plants, water loss through transpiration and factors affecting it.
Plant water relations and role of water in crop evapo-transpiration, its measurement and the factors influencing it, Water stress in plants and its effect on growth, quality and yield.
Water relationship of cell and whole plant, Water and ion uptake by plants and its movement mechanism, Solute content and its movement.
Weather parameters influencing soi-water-plant relations and its measurements, climate characterization/Agroclimatic zoning and indices, introduction to microclimate/macroclimate in crops.
Determination of soil texture and bulk density; Determination of field capacity; Determination of soil moisture characteristics curve; Determination of hydraulic conductivity; Determination of infiltration rate; Measurement/monitoring of soil temperatures, RH, wind velocity, rain, evaporation, sunshine, dew, solar radiation etc.; Determination of matric potential; Determination of RWC, LAI, LWP, SDI etc.
