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.

    Effect of continuous N P K Fertilization on the growth and yield behaviour of coconut with special reference to potash nutrition and its interrelation with other mineral nutrients
    (Department of Agronomy, College of Agriculture, Vellayani, 1985) Pushpangadan, K; KAU; Sadanandan, N
    At the Coconut Research Station , Balaramapuram in Trivandrum District of Kerala State an experiment was laid out in 1964 to assess the growth characters, yield attributes and yield of coconut variety West Coast Tall. The study was further enlarged to include the critical levels of leaf nutrient concentration as related to yield and the soil fertility statusdue to continued NPK fertilization . The treatments consisted of three levels of N, P and K (N-0, 340, and 680 g;P-0, 225 and 450 g and K-0, 450 and 900 g per palm per year). The experiment was laid out in a 3 raise to 3 partially confounded factorial design with two replications. Application of N enhanced the growth characters viz., production of female flowers, percentage fruit set, yield of nuts, weight of nuts, mean thickness and weight of meat, weight of copra and oil percentage. However the effect of N was found to be quadratic at the highest level applied. Application of P although improved the female flower prodcuction, its effect was negative towards copra weight and oil percentage . For the remaining characters studied, the initial level of 225 g per tree per year was found to be adequate.

    Studies on the interactive effects of water regimes, weed control treatments and nitrogen levels in direct-seeded rice
    (Faculty of the Post-Graduate School, Indian Agricultural Research Institute, New Delhi, 1984) Mohan Kumar, B; KAU; Singh, K N
    Field and green house experiments were conducted in the Division of Agronomy, Indian Agricultural Research Institute, New Delhi, during 1982 and 1983 to study the interaction of nitrogen x weed control x water regimes, on the growth, productivity and nutrient use pattern of direct seeded rice. The treatments in the field trails consisted of 4 levels of nitrogen (0, 50, 100 and 150 kg N ha-1). 3 weed control treatments (weedy check, butachlor, bentazone in 1982 and bentazone plus propanil in 1983) and 2 water regimes (continuously and intermittently flooded). The experiment was laid out in a split plot design, replicated thrice. The variables in the green house experiment were 2 rice cultivars (Pusa 33, drought susceptible and Pusa 312, drought tolerant), 3 nitrogen levels (0,100 and 200 mg N kg soil-1) and 5 soil moisture regimes (submergence to saturation, 0-0.025 MPa, 0-0.05 MPa, 0-0.075 MPa 0-0.10 MPa soil moisture tension).

    (Department of Agronomy, College of Agriculture, Vellayani, 1986) Ramakrishnan Nayar, T V; KAU; Sadanandan, N
    Field experiments were conducted at the coconut Research Station. Balaramapuram during 1983-84 and 1984-85 to study the production potential of cassava varieties Sreevisakham and Malayan-4, intercropped in coconut gardens, as influenced by planting density, growth regulators and different levels of NPK fertilisers. The cassava hybrid Sreevisakham was superior to the popular cultlvar Maiayan-4 in nuirber of nodes plant 1, number of functional leaves plant™1, leaf area index, net assimilation rate, crop growth rates, dry matter production, utilisation index, tuber bulking rate and in fresh tuber yield. For intercropping one hectare of coconut garden in which coconuts are spaced at 7.5 x 7.5 m, cassava plant population of 8000 (spacing 90 x 90 cm) was found to be optimum to produce maximum fresh tuber yield* Cassava plants at higher planting density, were stunted in growth and produced poor quality tubers. The growth regulators cycocel and ethrel though decreased the plant height, could not Influence either the yield attributes or yield and quality of cassava tubers.

    Agrotechniques for soil conservation in taungya systems
    (Department of Agronomy, College of Horticulture, Vellanikkara, 1986) Gopinathan, R; KAU; Sreedharan, C
    An experiment on 'Agrotechniques for soil conservation in taungya systems' was conducted at the Instructional Farm, College of Horticulture, Vellanikkara for a period of two years from May 1984 to April 1986. The objectives of the experiment were to asses the run-off, soil and nutrient losses as influenced by the important taungya practices and to evolve economically and ecologically viable agroforestry measures for soil conservation. Eucalyptus , the main tree component , was intercropped with the usually cultivated taungya crops of cassava and rice . The efficiency of cassava planting on ridges, grass farming and grass stripping was also investigated. There were seven treatments replicated thrice in RBD. Daily run-off and soil loss were quantified by installing multi-slot device consisting of 47 slots and brick masonry settling tank specifically designed for the project.
