Theory
Watershed concepts, objectives of watershed management, delineation of watershed, inventory of natural resources in watershed; soil erosion, types of erosion and erosion resistant and erosion permitting crops, contour bunds, graded bunds, terracing, water harvesting structures; recycling of runoff water- protective and supplemental irrigations; agronomic measures- suitable cropping systems, conservation tillage technique – in-situ conservations measures Micro irrigation: introduction, scope, different types of micro-irrigation systems, conventional surface and micro irrigation systems, principles, advantages, limitations and adaptability to crops; soil water availability, irrigation frequency, irrigation scheduling in micro irrigated crops; Wetting pattern and wetted area under sprinklers and emitters Fertigation – water soluble fertilizers; speciality fertilizers, components of micro irrigation system, design, installation of systems, operation and maintenance of systems fertigation equipments, uniformity co-efficient, monitoring and evaluation of these systems Problematic water –quality of water, classification of water, management of saline, sodic and sewage water, crop responses to problems waters |
