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.

    Functional diversity of an evergreen forest ecosystem of Vazhachal forest division, Kerala
    (Department of Forest Management and Utilisation, College of Forestry, Vellanikkara, 2016) Deepakkumar, R; KAU; Gopakumar, S
    The present study was carried out at Sholayar forest range of Vazhachal forest division of Thrissur district, Kerala state. The main objective of the study was to enumerate the species and functional diversity of selected aboveground and belowground biological components of this forest ecosystem. The study also aimed to understand the links between diversity, soil aspects, and functioning of the tropical west coast wet evergreen forest ecosystem. Five 0.1 ha (31.62 m x 31.62 m) sample plots were randomly laid in the selected grids in the Vazhachal forests as per the guidelines of National Working Plan Code 2014. A total of 175 plant species (<10 cm GBH) were recorded from the 0.5 ha (0.1 x 5 nos.) area in which 57 recruits, 29 shrubs, 28 herbs, 19 climbers, 14 pteridophytes, 13 polypores, 7 epiphytes, 4 orchids and 4 bryophytes. Palaquium ellipticum, Cullenia exarillata and Mesua ferrea are well represented young recruits. In addition, Dendrocnide sinuata, Psychotria nudiflora and Strobilanthus species were observed as dominant in the shrubby layer. Curcuma neilgherrensis, Pellionia heyneana and Oplismenus compositus are some of the herbs found in the herbaceous layer. Coscinium fenestratum, Leea indica, and Calamus species are the some of the important climbers found in the sampled sites. A total of 84 tree species were recorded from the 0.5 ha area with 1093 individuals per hectare and basal area of 85.43m2. Aglaia barberi, Cullenia exarillata, Mesua ferrea and Palaquium ellipticum were the dominated in the top canopy. Dipterocarpus indicus, Hydnocarpus pentandra and Myristica beddomei were observed in the middle storey. Garcinia wightii, Spondias pinnata and Strychnos nux-vomica were occupied in the lower canopy. Euphorbiaceae, Clusiaceae and Meliaceae were the dominant tree families. The diameter frequency as well as height frequency distribution of the sampled sites showed the reverse J shaped curve which reflects the healthy population structure. Margalef richness index (28.31), Shannon-Wieners index (4.08), Simpson index (0.9808) and Pielou`s index (0.6587). Rényi’s diversity profile and Principal Component analysis shows that there is smaller variation across sampled sites. The dominating plant functional traits are evergreen plant type (70.2%), simple leaf type (72.6%), glabrous textured leaf type (78.57%), smooth textured bark type (47.2%), medium thick bark type (53.5%), capsule fruit type (32.1%) and zoochory type (55.95%) of fruit dispersal which are typical of a tropical evergreen forest ecosystem. A total of 870 individuals of soil invertebrates under 28 different order were obtained from the 0.5 ha area. Isoptera, Hymenoptera and Coleoptera emerged as the dominant orders. Shannon- Wiener Index (2.40), Simpson Index of diversity (0.14) and Pielou's evenness Index (0.51) are soil invertebrates’ diversity. The population of Bacteria (44.4 x 106 cfu g-1), Fungi (26.3 x 103 cfu g-1), Fluorescent pseudomonads (18.3 x104 cfu g-1), Nitrogen fixers (14.4 x 104 cfu g-1), Actinomycetes (16.4 x 104 cfu g-1) and Phosphate solubilizers (20 x 103 cfu g-1). Soil temperature (19.82˚C), Bulk density (1.28g cm-3), Moisture content (29.06%), Sandy loam soil (Sand- 78.15%, Silt- 16.04% and Clay- 5.82%), Organic carbon (4.19%), Soil acidity (5.25) and Soil electrical conductivity (0.07mSm-1) are recorded during the study.
