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 salinity on survival, growth and breeding of the shrimp
    (Department of Aquaculture, College of Fisheries, Panangad., 1989) Ignatius, C A; KAU; Thampy, D M
    The present study has been undertaken with the major objective of elucidating the effect of salinity on survival, growth, ovarian development, fecundity, incubation period and batch hatching of the freshwater prawn Macrobrachium idella. Mortality of juveniles of M. idella which were acclimated at 0 and 20 ppt and treanferred abruptly to varying salinities, was found to start at 27.5 and 32.5 ppt respectively, whereas in those which were gradually acclimated from 0 to 45 ppt, it was found to start only at a higher salinity level of 37.5 ppt. The 120 Hr LC50 values were 30.90 + 0.7107, 35.89 + 0.7842 and 40.74 + 0.7402 ppt for the prawns acclimated at 0 and 20 ppt and for those gradually acclimated respectively. Thus it could be seen that this prawn is a highly euryhaline one and that acclimation at a higher salinity level and gradual acclimation have got advantage in extending the upper tolerance level. Growth was found to be significantly influenced by salinity, being highest at 0 – 10 ppt, lower at 15 ppt and almost nil at 20 ppt and beyond. Sporozoan infection was noticed in the prawns reared at 15, 20 and 25 ppt. Salinity was found to have no significant influence on fecundity, while ovarian development is being influenced by it. The rate of ovarian development was high at 6 and 12 ppt and low at 0 ppt. Incubation period, which takes about 13 – 15 days was not found to be influenced by salinity, while there was some effect on batch hatching, the rate of which was more at 0 ppt and less at 6 ppt. During incubation, mortality of eggs due to infection was observed only at 0 ppt. Thus, it could be seen that a salinity level of around 6 ppt is ideal for ovarian development, maximum fecundity and synchronous hatching.
