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.

    Genic status in relation to radlosensltlvity, mutation frequency and spectrum in Bhindi
    (Department of Agricultural Botany, College of Agriculture, Vellayani, 1985) Mareen Abraham; KAU; Krishnan Nair, N
    The effect of 30 RR ^Co-gamma rays on different genotypes of Bhindi (Abelmoschus esculentus Moench) have been studied in detail in M1 and M2 generations, The experiments were conducted during 1981-83 at the Department of Agricultural Botany, College of Agriculture, Vallayani, There were 20 different genotypes including both pure and hybrid seeds. The M1 generation was laid out in RBD with two replications and maintained following the package of practices recommended for this particular crop. The radio sensitivity of the different genotypes wore tested based on the direct effect of the mutagen in M1 generation. The treated hybrid materials along with their control, parental varieties and 30 kR exposed parental types were carried further to H2 generation to assess the extent of variation created in the segregating M2 generation. Proper lay out, maintenance of the crop and data collection were followed in segregating generation also. The data collected were statistically analysed for proper interpretation of the results obtained. To assess the direct effect of the mutagen in M1 generation various growth metrics such as germination percentage, days to complete germination, plant height, number of loaves and branches per plant at 30 days interval, pollen and seed sterility and various fruit characters including yield per plant were taken into consideration. All the characters analysed showed difference in expression depending on the genotypes concerned. Majority of the growth characters showed significant reduction in gaiapa ray treated population compared to their respective controls. A delay in germination was noted in majority of the genotypes. Growth metric analysis clearly demonstrated that eventhough treatment delays the crop growth in early stages, at later phases of growth the plant rectifies itself and attains maximum expression as in the case of control population. All the genotypes tested showed increased pollen and seed sterility due to gamma ray exposure, which directly influences the number of fruits produced per plant. Yield per plant showed significant variation among the treatments and in majority of the genotypes gamma rays significantly reduced yield potentiality of the plants* Based on seed sterility percentage, it was possible to group the plants under low, medium and high sterile types.
