Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Mathematical model for sediment yield in agricultural watershed
    (Department of Land and Water Resources and Conservation Engineering, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 1998) Babu, V; KAU; Remadevi, A N
    The knowledge of temporal distribution of sediment yield is required in the design and operation of soil and water conservation programmes on watershed basis. For the project planning purposes, the estimates made are mostly based on experience. Such estimates are very approximate and grossly inadequate for engineering analysis. Therefore there is an urgent need for , rational analysis of erosion data from catchments, inorder to obtain relationship for erosion rate. Therefore a mathematical daily sediment yield model is developed for Thuthapuzha drainage basin (940 km2 ) of Bharathapuzha basin, corresponding to Muskingum routing equation. The model is based on combined approach of translation and routing for simulating sediment graphs. Thirty seven selected storm events of the drainage basin observed during 1986- 92 are used for estimation of model parameters by Lagrange multipliers method and three storm events of 1993 are used for verification of the model. The model is used to compute temporal distribution of suspended sediment yield on storm basis and their performance is evaluated both qualitatively and quantitatively. Mathematical relationships of mobilized ~ sediment with effective rainfall; computed sediment flow rates with observed sediment flow rates and observed and computed sediment flow with effective rainfall and mobilized sediment were also established. The Correlation Coefficient of all those equations are found to be close to one. The statistical measures of Percentage Absolute Error in peak sediment flow rates, Absolute Prediction Error, Integral Square Error, Correlation Coefficient and Coefficient of Efficiency of the model are obtained as 3.9934, 9.0007, 5.3286, 0.9951 and 0.9659 respectively. The study reveals that the developed model is a very effective tool in the real time forecasting of sediment yield in Thuthapuzha drainage basin.
