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 food intake, conversion efficiency and growth of the prawn Metapenaeus Monoceros (Fabricius)
    (Department of Aquaculture, College of Fisheries, Panangad., 1990) Suresh Babu, C; KAU; Thampy, D M
    Salinity tolerance of the juveniles of the prawn Metapenaeusmonoceros (Fabricius) was found out by abrupt exposure to high and low salinity levels after acclimation at 25 ppt salinity. 100% mortality was recorded both at zero and 50 ppt and no mortality between 5 and 35 ppt. The lower and higher LC50 values for 120 Hr. period were 1.03 + 0.51 and 42.67 + 0.52 ppt respectively. The juveniles with mean wet weight of 0.4728 + 0.0893 g (41.52 + 6.48 mm TL) were grown at 5, 15, 25 and 35 ppt salinities for 35 days (first experiment), to find out the effect of salinity on food intake, growth, conversion efficiency and assimilation efficiency. Food intake was found uniform throughout the test salinity levels. Growth and assimilation efficiency were comparable between 25 and 35 ppt but conversion efficiency was higher at 25 ppt salinity. Similarly, growth and conversion efficiency were higher at 25 ppt than at the lower test salinities (5 and 15 ppt), even with a significantly lower assimilation efficiency. Growth, conversion efficiency and assimilation efficiency were not significantly different between 5 and 15 ppt as well as between 5 and 35 ppt salinities. Prawns at 15 ppt showed growth and conversion efficiency comparable to that at 35 ppt though assimilation efficiency was more at 15 ppt salinity. In the second growth experiment M.monocerosjuverniles of mean wet weight of 0.4996 + 0.0695 g (42.13 + 5.62 mm TL) and of 1.5483 + 0.1875 g (63.19 + 5.16 mm TL) designated as group I and group II respectively were grown at 20, 25, 30 and 35 ppt salinities for 30 days, to compare food intake, growth, conversion efficiency and assimilation efficiency between the two size groups. In the group I prawns, food intake, growth, conversion efficiency and assimilation efficiency were comparable among the four test salinities. This was the case with group II prawns also with respect to food intake and growth. In group Ii prawns conversion efficiency was significantly higher at 25 ppt than at 30 and 35 ppt, and significantly lower at 35 ppt than at 20 and 25 ppt salinities. Comparable conversion efficiency was obtained between 20 and 25 ppt, 20 and 30 ppt and between 30 and 35 ppt salinities. The lowest assimilation efficiency was recorded at 35 ppt while at all other test salinities, it was more or less uniform. The comparison between group I and group Ii prawns showed that the percentage food intake and percentage weight increase were higher in group I prawns. They also showed higher conversion efficiency at 20, 30 and 35 ppt salinities, but the value for 25 ppt was comparable to that of group Ii prawns. Assimilation efficiency of the two size groups were not different among 25, 30 and 35 ppt salinities but at 20 ppt, group I prawns had lesser assimilation efficiency than group Ii prawns. The dry weight balance, in both growth experiments, showed high assimilation efficiency and comparatively low growth efficiency (K1 and K2) values in all treatments, indicating higher protein requirement in the diet for M. monoceros.
