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.

    Irrigation scheduling and moisture conservation in water melon
    (Department of Agronomy, College of Horticulture, Vellanikkara, 2000) Ajith, C B; KAU; Joseph, P A
    An experiment was conducted at the Agricultural Research Station, Mannuthy, Thrissur during the period from December 1998 to March 1999 to study the influence of levels of irrigation and moisture conservation methods on the growth and yield of water melon (Citrullus fanatus) grown in rice fallows. The experiment was laid out in randomized block design with three replications. The treatments consisted of combinations of four moisture conservation methods (control, application of paddy waste as surface mulch, uniform incorporation and bottom layer application @ 1/3 pit volume) and four levels of irrigation (IW /CPE ratio of 0.6, 1, 1.4 and farmer's practice of daily irrigation @ 20 lit pit"), The study revealed that incorporation of moisture conservation materials increased the growth attributes like length of vine, number of leaves per vine, leaf area and dry matter production and yield attributes like weight of fruits and number of fruits per plant. Among moisture conservation methods surface mulch and uniform incorporation of paddy waste were found to be superior in most of the cases. Watermelon responded very well to irrigation. Biometric characters (length of vine, number of leaves per vine, leaf area and dry matter production) and yield attributing characters (weight of fruits and number of fruits per plant) were favourably influenced by frequent irrigations. The fruit yield increased with increase in frequency of irrigation and was maximum at IW /CPE ratio of 1.4. Results of soil moisture studies revealed that incorporation of moisture conservation material' increased the soil moisture content, consumptive use and water use efficiency. The consumptive use increased with the frequency of irrigation. The top 15 cm of the soil layer accounted for the highest soil moisture depletion. The depletion was more from the deeper layers in the drier regimes. Field and crop-water use efficiencies were higher in less frequently irrigated treatments. Higher levels of irrigation increased N, P and K content of leaves. No convincing change in leaf N, P, K content could be brought about by the incorporation of paddy waste. Economic analysis showed that incorporation of paddy waste could increase the net profit. Net profit as well as net return per rupee invested were the highest with scheduling irrigation at IW/CPE ratio of 1.4. Among the treatment combinations, the best combination was surface application of paddy waste with irrigation at IW/CPE ratio of 1.4 followed by the combination of surface mulching and fanner's practice of daily irrigation.
