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 shade levels on growth and vigour of seedlings of terminalia species in the nursery
    (Department of tree physiology and breeding, College of Forestry, Vellanikkara, 2002) Prasad, G; KAU; Gopikumar, K
    The present study was undertaken at the College of Forestry, Kerala Agricultural University, Vellanikkara, Thrissur during the period from 2000 to 2002 to evaluate the effect of various shade levels on the growth and vigour of seedlings of tembavu [Terminalia tomentosa var. crenulata (Roth.) C1.], thanni [t bellirica (Gaertn.) Roxb.] and neermaruthu [T. arjuna (Roxb. ex DC.) Wt. & Am.] in the nursery. The study revealed that in general, in all the species examined, shade exerted significant influence on growth and vigour of the seedlings in the nursery. In T. tomentosa and T. bellirica, 50 per cent shade produced best results with regard to shoot growth parameters like height and collar girth while in T. arjuna, 75 per cent shade was found to be most ideal with regard to these growth parameters. In general, in all the species, seedlings grown under 75 per cent shade produced maximum leaf number and area. The root growth parameters viz., length and spread . were found to be the maximum when grown under 50 per cent shade in T. tomntosa and T. bellirica, while 75 per cent was found to be the best for T. arjuna. Similarly, 50 per cent shade was found to be better for T. bellirica and T. tomentosa withregard to biomass production. However, T. arjuna responded well to 75 per cent shade in this regard. No clear cut trend was seen in the chlorophyll production with regard to the different shade levels in any of the three species studied. However, chlorophyll a, chlorophyll b and total chlorophyll content was slightly higher when grown under 75 per cent shade conditions. The highest number of stomata was seen when the plants were grown under full sunlight. In all the species, the nitrogen content was found to be highest for seedlings grown under 75 per cent shade while the highest potassium content was recorded when grown under 50 per cent shade. However with regard to the phosphorus concentration, 25 per cent shade was found to perform better in T. tomentosa and T. arjuna while 50 per cent performed better in T. bellirica.

    Response of sandal (Santalum album Linn.) seedlings to shade and mycorrhizal association
    (Department of tree physiology and breeding, College of Forestry, Vellanikkara, 2002) Binu, N Kamalolbhavan; KAU; Ashokan, P K
    The occurrence of sandal- Arbuscular Mycorrhizal Fungi (AMF) associations in natural sandal growing forests and the response of sandal seedlings to inoculation with commonly available cultures of AMF, shade levels and nature of hosts were investigated in a pot culture experiment at the College of Forestry, Kerala Agricultural University, Vellanikkara. Two important sandal growing regions in the state, Marayoor (ldukki district) and Wadakancherry (Thrissur district) were selected for this study and a non-sandal growing area in Thrissur district was selected as a control for the soil studies . • The result showed that characters like height, number of leaves, leaf area and shoot weight of sandal seedlings increased due to the Arbuscular Mycorrhizal Fungi inoculation and maximum response was observed for seedlings grown in soils inoculated with Glomus mosseae. The characters like collar girth, root weight did not show any significant difference for the mycorrhizal inoculation. It was further observed that the interactions between shade and mycorrhizae were the best under 50 per cent shade level especially for those seedlings inoculated with Glomus mosseae. During the initial seedling phase, high shade (75 per cent) is needed for sandal, but during the later stages of seedling growth, medium shade (50 per cent) resulted in best growth of seedlings. Growth of sandal seedlings with two host species, casuarina and redgram was on par. The relative water content and plant water potential were higher in seedlings inoculated with AMF. The N, P, K content of the shoot of sandal seedlings were maximum for seedlings inoculated with Glomus mosseae. Sandal seedlings collected from natural sandal growmg regions investigated for the presence of sandal-AMF association revealed that the roots of sandal seedlings from Wadakancherry forest showed 33 per cent of colonization, while the seedlings from Marayoor forest showed no colonization. Sandal seedlings grown for four months in the soils collected from these two regions showed superior growth when compared to those seedlings grown in soils from the agricultural lands of Thrissur, but no AMF colonization was observed in the roots of the sandal seedlings .
