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.

    Studies on foliar diagnosis, yield and quality of tapioca (Manihot utilissima Pohl.) in relation to nitrogen and phosphorus
    (Division of Agricultural Chemistry, Agricultural College and Research Institute, Vellayani, 1968) Vijayan, M R; KAU; Subramonia Aiyer, N
    An investigation was carried out at the Agricultural College and Research Institute, Vellayani during the year 1966-68 to evolve a suitable diagnostic technique for the nutritional status of nitrogen and phosphorus in two varieties of tapioca (M-4 and H-105) by foliar analysis. The response of the two varieties to graded doses of nitrogen (0.75 and 150 kg. N/ha.) and phosphorus (0.50 and 100 kg. P2O5/ha.) and their interaction in relation to the pattern of uptake, yield and quality of tubers were also investigated. Potassium and calcium were kept constant at 250 kg and 1200 kg. per hectare respectively. A split - plot experiment in R.B.D. with three levels each of nitrogen and phosphorus in factorial combinations as major treatments and with the two varieties as minor treatments, was laid out. Leaf leminae and peticles each grouped into three morphological categories. were used for testing the suitability for the diagnostic analysis. The plant part thus standardised (reflect) was analysed at three stages of growth for nutrient content. Biometric observations were recorded at three stages of growth. Yield components and quality factors of tuber were assessed in relation to nutrition of the plants.

    Estimation of loss of nitrogen from different nitrogenous fertilizers when applied to different soils under water-logged condition
    (Division of Agricultural Chemistry, Agricultural College and Research Institute, Vellayani, 1968) Krishnakumari, M; KAU; Subramoney, N
    The investigation envisaged the study of the loss of nitrogen due to leaching from different nitrogenous fertilizers applied to different types of soil and their comparative efficiency on the performance of rice variety I.R .8. The study has enabled the following conclusions to be drawn. 1. The loss of nitrogen by leaching is not reduced even when nitrogen is applied in the water insoluble form. 2. That the loss of nitrogen through leaching even from the fertilizer containing insoluble form of nitrogen might be due to the reaction between fertilizer and soil solution. 3. The loss of nitrogen depends on the texture of soil receiving nitrogenous fertilizers, maximum loss occurring in sandy soil and minimum in clayey soil. 4. The maximum loss of nitrogen through leaching occurs between 12 and 24 hours after the application of fertilizers.

    Effect of different forms and levels of phosphorus on the growth, yield and composition of three yielding varieties of rice (IR 8, Taichung Native I and Culture 28)
    (Division of Agricultural Chemistry, Agricultural College and Research Institute, Vellayani, 1968) Jagadeeschandran Nair, M P; KAU; Koshy, M M
    To study the effect of different forms and levels of phosphorus on the growth, yield and composition of three high yielding varieties of rice, a pot culture experiment was carried out in the Agricultural College and Research Institute, Vellayani, in a randomised block design with 39 treatments and 3 replications. The different forms of phosphorus used were superphosphate, ultrafos, defluorinated rock phosphate and Thomas phosphate. The levels of application were 0,25, 50 and 75 kg P2O5/ha. The rice varieties studied were Culture 28, IR 8 and Taichung Naive 1. The main findings of the experiment are summarised below: 1) The height of plants was a maximum for IR 8. This growth character was not influenced by the form of phosphorus used, but it increased significantly with increase in the rate of phosphorus application, 2) In the matter of tillers, Taichung Native 1 was superior to IR8 and Culture 28. Of the different forms of phosphorus applied, superphosphate and deflurinated rock phosphate produced the maximum number of tillers. As regards the effect of level, the number of tillers increased with increase in the level of phosphorus application.
