Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    STUDYING VARIABILITY IN OBSERVED SOIL INFILTRATION RATES AS INFLUENCED BY INFILTROMETERS OF VARIED CONFIGURATIONS
    (AAU, Anand, 2015) PRATEEK KUMAR; Dr. M. L. Gaur
    Infiltration remains the weakest link in hydrology and still has very much scope for its search and research at various scales in the Time- Space domain. The standard ‘double ring infiltrometer method’ uses to be the major and most widely adopted procedure for generating infiltration values, where two standard rings of diameters 300 and 600 mm are adopted. Additionally to save water and made it easy , sometimes researchers uses single infiltrometer rings too, where the end results have its own shortcomings in particular the influences of lateral downward flows during the tests. In both the cases i.e. the single ring infiltrometer as well as double ring infiltrometer, very often a constant water head of 50-75 mm is maintained during conductance of infiltration test. In present study an innovative effort is made , where few rings of alternative sizes ( 54 mm, 108 mm) are considered and used for conducting several repetitive infiltration tests over prevailing soil – vegetation land cover configurations and comparing the performances with the similar simultaneous results obtained by a standard single ring ( 300 mm dia) for the same test location and conditions. Similarly, two different configurations double ring infiltrometer ( 54 & 108 mm; v/s 300 & 600 mm) too were synthesized and compared herein in for getting an in-depth idea about the trends and magnitudes of variations in infiltration rates and volumes for various land use covers are adopted in the study and whose detailed description is provided in relevant chapters. Beside the traditional ring infiltrometers, a couple of square shaped infiltration basins too were utilized in present study having water spread areas of even up to 1 square meter. Beside conducting infiltration test runs for monitoring rates and volumes of infiltrated water, additional transparent acrylic infiltrometers were too designed and fabricated for monitoring the advanced downward movement of infiltrated water fronts under variety of conditions.
