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.

    Effect of sedatives on penaeus monodon fabricus seed under oxygen packing for transportation
    (Department of Aquaculture, College of Fisheries, Panangad, 1991) Joshi, K; KAU; Jayasree Vadhyar, K
    The study was performed with the objective of selecting a sedative at a suitable dose and testing its effect along with other factors viz. packing density, salinity and temperature on the P.mondon seed under oxygen – packed transport conditions. The selection of a sedative at an appropriate dose, from those tried viz. chloral hydrate, MS-222 and tertiary butyl alcohol, was made by conducting statistically designed experiments on the survival of the treated and untreated prawn seed for 72 hours in open containers and on the metabolic activities of the treated and untreated prawn seed for 2 hours. The experiment to find out the effect of the selected sedative was carried out in specially designed hard plastic containers fitted with facilities fpr packing oxygen under uniform pressure. The experiment was conducted as an asymmetrical factorial experiment with 4 levels of packing density (200/1, 400/1, 600/1 and 800/1) and 2 levels of sedation (without and with sedation), salinity (25 ppt and 20ppt) and temperature (29+ 10C and 23 + 20C). Chloral hydrate was selected at a dose of 400 ppm for application on P.monodon post –larvae under oxygen – packed conditions. The application of chloral hydrate on the prawn seed under oxygen packing at the selected dose evidently showed a negative effect. A lower dose (300 ppm) than the selected dose, studied separately, also showed similar results under oxygen packing . An increase in packing density decreased the time of initial mortality and percentage survival. At packing densities of 200/1, 400/1, 600/1 and 800/1, the safe durations of transport (duration of 100% survival) were 7.5 h,5 h, 3.5h and 2.5 h respectively at ambient temperature of 29+ 10 C. In P.monodon seed transport the number of seed has been found as more important than their weight in deciding the survival. A high salinity of 25 ppt was found better than a lower salinity for P.monodon seed transport. Lowering of temperature of the packing medium, rather than applying sedatives or lowering of salinity, has been found as a suitable method for increasing the survival during oxygen – packed transport of P.mondon seed. At the lowered temperature of 23+ 20C significantly longer duration of 100% survival (15h at 200/1 and 5 h at 800/1) and better percentage survival at 24 hours (92.5% at 200/1 and 83.13% at 800/1) than at the ambient temperature could be observed.
