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.

    Development of a filter system for roof water harvesting
    (Department of Land and Water Resources and Conservation Engineering, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 2014) Shijila, Erikottil; KAU; Sathian, K K
    This thesis work was undertaken to study the performance of modified mesh filter under rainfall. The mesh filter was modified with two other filters such as sand and charcoal filter and their combination study was conducted on artificial rainwater and evaluated the quality of filtered water. The two filters are fabricated with naturally available material such as above 1 mm size coarse sand and small pieces of burned coconut shell. These materials are freely available from surroundings and each material was filled in each PVC pipes of 25 cm length. From the first study four buildings are selected in the campus have different impurity levels that because of rain fall events, purposes or constructed material. It was found that there are small variations in the quality of harvested water but after filtration all results are same because filter was not depends on the roofing material and impurity level. The quality parameter like pH of the rainwater harvested after the filtration with mesh filter for all roofs met the USEPA secondary drinking water standard range of 6.5-8.5. The electrical conductivity, turbidity and suspended solids are also met the drinking water standards by WHO and the calculated average filter efficiency of mesh filter was 81.3 %. From the filter combination study the quality parameter such as pH, electrical conductivity, turbidity and suspended .,olids also examined through water quality analyzer of collected samples. As per the BIS 10500 of 2004 and WHO all the results are in the permissible range. The BOD test result was ranging from 44 to 92 mg/l and compared to inflow the filtered water has drastic reduction in the values. From the coliform test it was cleared that there were no colifirms (011 OOml) in the filtered water after 24 hour incubation period where as in inflow water coliforms were detected. It was found that there is a marked reductio'. .n the concentration of impurities, The reduction in im urities ranges from 84 to 86 % and the charcoal tilter has highest filtration rate of 9.42 m3/minlm2 compared to others. The results clearly. revealed that combined filters remove the impurities in a more efficient manner than of the mesh filter developed earlier. There is only minor difference between the both filters. The results clearly revealed that combined filters remove the impurities in a mo: e efficient manner than of the mesh filter developed earler.
