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.

    Quick wilt disease of pepper (Piper nigrum Linn)-1 symptomatological studies on the quick wilt disease of pepper
    (Department of Plant Pathology, College of Horticulture, Vellanikkara, 1978) Mammootty, K P; KAU; Abi Cheeran
    The present study on the quick wilt disease of pepper caused by Phytophthora palmivora (Butler) Butler was conducted at the Pepper Research Station, Vellanikkara using Panniyoor-1 pepper variety. The objectives of the investigations were to study the symptoms of the disease and to find out suitable control measures using fungicides. The first visible symptom on leaf, stem and root was noticed 24 to 48 hours; two to five days and 24 to 48 hours respectively after inoculation, depending on the maturity of the plant part. A fully developed lesion had a dark brown hononecrotic centre and plesionecrotic boarder surrounded by yellow halo. The yellow halo was not noticed during prolonged wet and humid conditions. Under these conditions lesions was uniformly brown in colour. Zonations were noticed during the alternate wet and dry conditions. On the stem, branches and roots symptom usually developed as a uniformly brown and dark coloured lesions. Pathogen entered mainly though lower surface of the leaf. After infection, defoliation took place within five to ten days. Development of flaccidity, drooping and defoliation of the leaves were the marked symptoms during the progress of disease when the stem, branches or roots were infected. All the fungicides tested checked the growth of the fungus in vitro for a period of three days. The fungicides when sprayed or drenched two hours before inoculation completely checked the disease. However, there was mild infection on plant where Dithane M-45 was used for drenching the soil. As the interval between the fungicidal spray and inoculation prolonged there was progressive reduction in the control of the disease. None of the fungicides was able to eradicate completely the established pathogen on leaves. When fungicides were applied one day after inoculation there was complete control of the disease on stem. While the control was not complete when it was applied two days after inoculation. All the fungicides except Dithane M-45 completely checked the development of the disease when they were drenched in soil.

    Studies on the bacterial blight (Wilt) of Tapioca incited by Xanthomonas manihotis (Arthaud-Berthet) Starr
    (Department of Plant Pathology, College of Agriculture, Vellayani, 1979) Mani, T Cherian; KAU; James Mathew
    The bacterial blight of tapioca, incited by Xanthomonas manihotis (Arthaud-Berthet) Starr, probably the most serious of all the diseases recorded on the plant, was reported sporadically from different parts of Kerala since 1975. The disease is characterised by loss of turgidity, shrivelling and wilting of leaves, gum extraction, die-back and death of shoots, vascular discolouration of stem and roots and damage and decay of tubers. The pathogen was confirmed to be Xanthomonas manihotis from morphological, physiological and biochemical studies coupled with symptomatology and host specificity. The pathogenicity was confirmed on tapioca using different methods of artificial inoculation, of which inoculation after nipping the bud was found to be the best.

    Studies on the mosaic disease of snake gourd (Trichosanthes Anguina L.)
    (Department of Plant Pathology, College of Agriculture, Vellayani, 1978) Joseph, P J; KAU; Ramanatha Menon, M
    A mosaic disease of snake gourd (Trichosanthes anguina L.) caused by a virus, was investigated which was prevalent at Vellayani and nearby localities. The symptoms manifested as mosaic and formation of dark green blisters on the lamina was also observed. The affected leaves were severely reduced in size, variously crinkled and malformed. Growth was retarded and internods were shortened. The infected plants blossom sparingly and set only very few fruits. The affected portions of the leaf were thinner than healthy areas, palisade cells reduced in size and loossly packed. The mesophyll cells contain only few chloroplasts.

    Rhizoctonia damping off of Cardamom (Elettaria cardamomum Maton) and its control
    (Department of Plant Pathology, College of Agriculture, Vellayani, 1978) Sasi, P S; KAU; Wilson, K I
    The role of Rhizoctonia in causing damping off of Cardamom in the primary nursery was established and the symptoms of the disease have been described . The fungus grew well on a number of solid media. The morphological characters of the fungus were studied. It was able to infect 27 plant species including Achyranthes aspera, Commelina benghalensis, Phyllanthus niruri Colonyotlon -puricatum Cyperus rotundum, Abutilon indicum, Heliotropiumindicum and Azolla pinnata on artificial innoculation . These plants have been found to be new hosts o f the fungus in our country. The pathogen was Identified as Rhizoctonia solani Kuhn.
