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.

    Performance study of hydraulic ram by varying length and inclination of supply pipe
    (Department of Land and Water Resources and Conservation Engineering, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 1991) Rathnakumar, V K; KAU; George, T P
    In India, the agricultural production in many years is hampered by the non availability of the adequate power for irrigation. The shortage of power often affects the lift irrigation project. Main problems in enhancing irrigation facilities in hilly regions are their highly uneven topography and non availability of conventional sources of power. The increasing exploitation of conventional energy sources for meeting the increasing power demands is becoming expensive. Under such circumstances, devices like hydraulic rams are to be efficiently designed for lifting water in regions where adequate supply of water and favourable conditions for installations for hydraulic rams exists. Hydraulic ram is a simple automatic device, which uses the kinetic energy of a large quantity of flowing water available at lower elevation to lift a portion of it to a higher elevation. The simplicity of construction and the automatic operation make it especially adaptable to remote areas. The performance study of hydraulic ram was evaluated mainly by observing the delivery head and delivery discharge relationships. In each case, the efficiency was evaluated. Typical performance characteristics were plotted for the changes in conditions of operations. Effect of the performance of the hydraulic ram was studied by changing length of supply pipe, L/D ratio of Air chamber, volume of Air Chamber and inclination of supply pipe. The major findings of the research work are : 1. The ram shows best range of efficiency of operation for 14 and 15 metre lengths of supply pipe. 2. The L/D ratio of Air chamber have no significant effect on the values of delivery discharge, efficiency and delivery head for a given volume. 3. The delivery discharge increases with increase in volume of Air chamber, but the rate of increase in delivery discharge decreases with increase in volume of Air chamber. 4. The continuous operation of hydraulic ram have no significant effect in higher volumes of Air chamber. 5. The hydraulic ram shows best range of efficiency of operation at 7 degree inclination of supply pipe than the 8.5 and 6 degree inclinations.
