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.

    Evaluation and refinement of low cost automation system for naturally ventilated greenhouse
    (Department of Soil and Water Conservation Engineering, Tavanur, 2019) Jinu, A; KAU; Abdul Hakkim, V M
    Greenhouses are structures used for offseason cultivation of crops and also for obtaining maximum production from unit area. In greenhouses, crop growing environment as well as growing medium can be modified by adopting suitable technologies for microclimate control and water and fertilizer application. Manual controls of microclimate and water and fertilizer application are time and labour consuming and hence automation is required for the better greenhouse management. The study entitled “Evaluation and refinement of low cost automation system for naturally ventilated greenhouses” was conducted during the period July 2015 to February 2017 to modify the existing low cost automation system at ARS Anakkayam and also for its performance evaluation. Existing automation system has limitations such as it cannot manage temperature and relative humidity separately and also it cannot manage irrigation and fertigation. These problems were rectified in refined automation system. The refinement of the system was done by changing the microcontroller used in the automation system and also using a timer for the timely management of irrigation and fertigation. The refined system was capable of managing temperature and relative humidity separately and performing irrigation and fertigation operations inside the greenhouse. The refined automation system was tested without crop and with crop during three crop seasons with salad cucumber crop (variety Saniya) inside the greenhouse. The experiment was conducted inside a naturally ventilated greenhouse situated at the ARS, Anakkayam, under Kerala Agricultural University. For comparison, salad cucumber was cultivated inside another greenhouse which is manually controlled. Microclimate as well as crop data were collected from outside the greenhouse and both these greenhouses and compared. The temperature inside the AGH was less compared to NAGH and the relative humidity inside the automated greenhouse never exceeded above 70%. The yield and all other crop parameters were better in AGH compared to NAGH.
