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.

    Shade response of common rainfed intercrops of coconut
    (Department of Agronomy, College of Horticulture, Vellanikkara, 1981) Lalitha Bai, E K; KAU; Vikraman, R
    An experiment was conducted at the College of Horticulture, Vellanikkara during 1980-81 to study the shade response of five common rainfed intercrop of coconut garden. The experiment was laid out in randomised block design with four levels of shade and five replications. The study revealed that sweet potato cannot be cultivated under shade as it is a ‘shade –sensitive’ crop,while coleus is suitable only where light infiltration is high. Colocasia, turmeric and ginger were found suitable for intercropped situations. Colocasia appears to be shade – tolerant while ginger and turmeric are indicated as ; shade – loving’. These two shade – loving crops are best suited under shaded situations up to 25 and 50 per cent shade, respectively . Photosynthetic mechanism appears to have a decisive role on the shade response of all these crops expecting sweet potato. Excepting colocasia, plant height (length of vine) in all the crops increased with increasing shade intensities. Number of branches (tillers) in all the crops significantly decreased with increasing intensities of shade. The content of total chlorophyll and its components were significantly influenced by shading in all the crop. The contents of nitrogen, phosphorus and potassium in all the plant components of all crops increased because of shading. The uptake of all the nutrients followed an identical pattern as that of dry matter accumulation in all the crops.

    Effect of shade and moisture regimes on the growth of cocoa seedlings
    (Department of Agronomy, College of Horticulture, Vellanikkara, 1981) Gopinathan, R; KAU; Vikraman Nair, R
    An experiment was conducted at the College of Horticulture, Vellanikkara during 1979-80 on the effect of shade and moisture regimes on the growth of cocoa Theobroma cacao L.) seedlings. The investigations were carried out to arrive at the optimum shade and moisture requirement for the growth of cocoa seedlings. The experiment was laid out in a completely randomised design with four levels of shade and three levels of moisture with four replications. The study revealed that cocoa seedlings must be shaded and well watered for their better growth. 50 – 55% shade and irrigation at 75% available moisture was found best. Death of all the seedlings in the open by the third month of observation stresses that, cocoa seedlings cannot be grown without any shade irrespective of the frequency of irrigation. Expect net assimilation rate (NAR) and leaf area ratio (LAR) all the growth characters were increasing with increasing shade (up to 50 – 55%) and increasing frequencies of irrigation.
