Agricultural engineering has been applying scientific principles for the optimal use of natural resources in agricultural production for the benefit of humankind. This particular course deals with application of both irrigation and drainage principles in agriculture for achieving profitable crop production with minimal environmental implications. This is one of the core courses of Agricultural Engineering program recommended for under graduate and graduate students. In this course we will focus on soil- water-plant-atmosphere relationship, crop water requirement, irrigation scheduling, irrigation water conveyance, measurement of irrigation water, water application methods, irrigation systems design and their performance evaluation, drainage of agricultural lands, management of salt affected soils, performance evaluation of drainage systems, ground water hydrology, irrigation wells and water-lifting devices-pumps. It involves weekly quizzes, in-class numerical problem solving, assignments and class tests.
