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.

    (Anand Agricultural University, Anand, 2016) HEPIN D BHANDERI; Dr. M. L. Gaur
    A field experiment was conducted under farmer’s scenario to study the comparative performance of drip and furrow irrigated tomato crop in an experimental field located inside the Kakanpur experimental research farm of CAET Godhra in tribal dominated Panchmahal district of Middle Gujarat. The experiment was aimed to learn and visualize the relative benefits /field performances of various simpler configurations of irrigation schedules, keeping focus towards prevailing conditions and farmers in the region. These simpler treatments consist of Drip applications of irrigation water encompassing actually required as well as deficit irrigation volumes at pre-identified time intervals, meeting the set irrigation demands. Three specific irrigation regimes being 0.6 ETc, 0.8ETc and 1.0ETc were adopted herein. The location specific daily values of ETc for the experimental plots during experimental period were worked out by adopting standard sets of procedures & protocols.

    DEVELOPMENT OF MINI TRACTOR OPERATED TWO ROW SEMI AUTOMATIC POTATO PLANTER
    (AAU, Anand, 2014) Raulaji Hardik k.; Dr. R. Swarnkar
    Potato is an important vegetable crop of winter season. Cultivation of potato is highly labour intensive because of non-availability of labour when it is carried out by labours with kodali and pavda. Delay in planting because of labour during season causes progressive decrease in yield. There is scarcity of labour during sowing operation of potato. The area under potato crop may increase if planting is mechanized through the mini-tractors. The use of planter will also improve the quality of planting in addition to removal of human drudgery during planting. Therefore project entitled “Development of Mini Tractor Operated Two Row Semi Automatic Potato Planter” was undertaken at Department of Farm Machinery and Power Engineering, Anand Agricultural University, Anand.

    EXPERIMENTAL INVESTIGATIONS ON FLOW CHARACTERISTICS OF FEW PROTOTYPE HYDRAULIC STRUCTURES UNDER VARYING DISCHARGE CONDITIONS
    (AAU, Anand, 2015) BARIA SONALBEN V.; Dr. M. L. Gaur
    The major objective of this dissertation work was to evaluate hydrologic and hydraulic functioning of a couple of prototype hydraulic structure as used in natural channels of small agricultural watersheds, by generating some of the basic information & other relevant parameters for area under study. The aim is to learn and realize true operations and functioning of such hydraulic structures under a flume condition with predetermined scientific objectives as elaborated in thesis. Physical model study play vital role in planning and designing of hydraulic structures. A vast review was done on updated progress on hydraulic structure and their relevant monitoring and evaluations in hydraulic flume as well as real channel flow conditions. The standard tilting flume facilities available in newly developed hydraulics lab of College of Agricultural Engineering and Technology (CAET), Godhra was effectively utilized for evaluation of above cited hydraulic structures under varied sets of discharges and channel bed conditions. The discharges inside the hydraulic flumes were varying in between 0.5 to 5 L/s in majority of experimental runs. Similarly the channel bed slopes were kept varying in between 0.5 to 2 percent longitudinal slopes. Efforts are made to derive the real limits of flow parameters, flow regimes, and all associated flow conditions. Also the values of Coefficient of Discharge (Cd) for five specific hydraulic structures are attempted here with an effort to further extend its applicability to similar ungauged situations. Not only the values of Cd are derived, but certain alternate predictive equations in this regards too also synthesized in this study.

    Hydrological Modeling of an Agricultural Watershed using HEC-HMS, Remote Sensing and GIS
    (AAU, Anand, 2015) PAMPANIYA, NIRAVKUMAR K.; Dr. M. K. Tiwari
    Runoff estimation is very important for water resources planning and management. Hydrological modeling is inevitable for accurate and precise estimation of runoff from a watershed. A major problem in the hydrological modeling is the inadequate field measured data to describe the hydrologic processes.With unavailability or limited availability of data, the quantitative understanding and prediction of the runoff generation processes and its transmission to the watershed outlet remains one of the most challenging area of hydrology. The use of remote sensing and GIS, in combination with semi distributed hydrological model provides new possibilities for deriving spatially distributed time series of input variables, as well as new means for calibration and validation of the hydrological model. In the present study, the HEC-HMS model is applied to the Hadaf river watershed, which is predominant with agricultural land and falls under semi-arid zone, where water resources planning and management is necessary for irrigation scheduling, water harvesting, flood control, drought mitigation and design of various engineering structures. In this study four different events of meteorological & discharge data, DEM, LISS-III and LISS-IV remote sensing imagery, soil maps are applied as inputs for HEC-HMS models. The effect of different resolution of DEMs, effect of land use change, effect of different resolution of land use imagery are also evaluated to assess their effectiveness in watershed delineation & drainage network, runoff generation, prediction accuracy, respectively. Two of the important transformation methods namely SCS UH and Clark UH are evaluated for performance comparison. Two of the important optimization methods (i.e. Univariate Gradient method and Nelder Mead method) are also evaluated to assess their effectiveness for rainfall runoff modeling. Initially, geo-morphological analysis of the watershed is carried out using the capabilities of remote sensing and GIS to prioritize the watershed for soil and water conservation measures. Then, conceptual hydrological HEC-HMS model is applied to transform rainfall into runoff for two of the selected event, and thereafter, the parameters related to initial loss, unit hydrographs, reservoir and channel routing, were calibrated and validated using the another two events in the watershed. It is found in this study that instead of low resolution (i.e. 90 m) SRTM DEM found to be better than ASTER DEM. Significant change in land use is observed from year 2008 to 2012 in this study. The finer resolution remote sensing image LISS-IV produced better classification and resulted in improved accuracy of HEC-HMS modeling. It is found that the Clark method produces better results than SCS-UH transformation method in rainfall-runoff simulation in terms of both the runoff peak and runoff volume. In parameter optimization, the overall performance of Nelder Mead method is found better than Univariate Gradient method. Better performance of all these models for the new event of rainfall-runoff transformation approves the applicability of HEC-HMS model in the study area. The findings in the present study are very useful for water resources engineers, researchers and will play an important role in water resources planning and management.

    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.

    (AAU, Anand, 2015) PATEL, Parth G.; Dr. R. Swarnkar
    Tillage is one of the most important practices of agriculture crops. Seed bed preparation requires primary and secondary operations which consume more time. The use of multipurpose tillage implement for primary and secondary operation simultaneously reduces time for seed bed preparation. Therefore a project entitled “Development of Mini Tractor Drawn Multipurpose Tillage Implement” was undertaken at Department of Farm Machinery and Power Engineering, College of Agricultural Engineering and Technology, Anand Agricultural University, Godhra. To achieve this objective a prototype multipurpose tillage implement consisting of frame, clod crusher and soil working tool was developed costing Rs.10, 723/-. The newly developed implement was tested in field condition to evaluate its performance.
