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.

    Molecular charecterization of taro bacilliform virus (TaBV)
    (Department of Plant Biotechnology, College of Agriculture, Vellayani, 2017) Aarathy, M B; KAU; Makeshkumar, T
    Taro is one of the world’s oldest food crop maintained by farmers for millennia and it has continued to spread throughout the world, as an important crop in Asia, Pacific, Africa and the Caribbean. Viral pathogens are one of the important factors threatening production of this vegetatively propogated crop. Taro viruses are poorly characterized, which is a hindrance to the safe movement of germplasm. The overall aim of this study was to detect the Taro bacilliform virus infecting taro and to characterize the virus at molecular level. Serological detection methods were not employed for the detection of TaBV. Molecular analysis with specific primers (TaBV like sequences) identified a new member among the badnavirus, Taro bacilliform CH virus, which was not previously detected in India. During the study 55 samples from different fields of CTCRI are selected to identify the different symptoms of Taro bacilliform virus infection. The symptoms and occurrence of TaBCHV is still not clear eventhough the samples shows different type of infections with infections in non-symptomatic ones also. Molecular analysis with badnavirus specific primers and further confirmation with PNG BadnaF/PNG Badna R reveals the presence of Taro bacilliform CH virus. It reveals that the RT/RNase H region was highly similar for Taro bacilliform and Taro bacilliform CH virus with <80 % similarity. Sequence and phylogenetic analysis confirms the sequences were more closely related to TaBCHV and exhibited 100 % similarity to TaBCHV isolates TaBCHV-1 and TaBCHV-2. From the Seven pair of primers were specifically designed inorder to characterize the whole genome of Taro bacilliform CH virus three pair of primers were used to successfully characterize the virus partially. To identify the phylogenetic relationship of the sequenced samples with that of available accessions, dendrograms were made using MEGA 5.0 software and the tree showed that sequences has variability eventhough lies within the group. It s clear from the study that the genome sizes of TaBCHV isolates, TaBCHV-1 and TaBCHV- 2 (Gen Bank Accession Nos: KP710178 and KP710177) were 7,641 bp, and it was within the badnavirus genomic range. The two islates almost shared about 98% genomic nucleotide identity. With other reported badnaviruses the genome sequence of TaBCHV-1 and TaBCHV-2 showed similarity to RYNV (44.1 %) and Fig Badnavirus (55.8 %)
