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.

    Impact of long term integrated nutrient supply system on soil health and rice productivity
    (Department of Agronomy, College of Agriculture, Vellayani, 2007) Raji S, Prasad; KAU; Babu Mathew, T
    A field experiment was carried out in both kharif and rabi seasons during 2004-2005 at Cropping System Research station, Karamana to find out the effect of long term integrated nutrient supply system on soil health and productivity of rice ( Oryza sativa L) –rice sequential cropping system. The experiment was laid out in RBD with 12 treatments in 4 replications and treatments in kharif and rabi together form one set of treatment. The treatments included control , 50% ,75% and 100% levels of RDF in kharif and rabi and 50% or 25% substitution of recommended dose of nitrogen in kharif substituted by organic manure viz. FYM , crop residues and green manure. The treatments exerted profound influence in majority of growth characters and yield attributes. Application of 25% or 50% substitution of RDF through organic manure along with 75% or 100% RDF in rabi through chemicals produced remarkable influence in growth and yield attributes. In grain and straw yield of rabi and kharif , the highest values were given by those treatments which supplied either 50% or 25% of RDF through FYM or crop residues in kharif and 100% or 75% of RDF through inorganic fertilizers in rabi .Since these treatments were on par with each other, the best treatment is that which supply 25% RDF through organic manure in kharif and 75% of RDF through inorganic fertilizers in rabi since25% of the chemical fertilizers are saved there. The highest NPK contents in grain and straw in both kharif and rabi were recorded and mostly in those treatments with 50% or 25% of RDF through organic manures in kharif along with 100% or 75% of RDF through in organics in rabi The highest NPK uptake in all the crop stages in both kharif and rabi were also higher observed in plots those receive 50% or 25% of RDF through organic manures in kharif along with 100% or 75% of RDF through in organics in rabi The soil available P and K values did not vary remarkably in both Kharif and rabi .However soil available nitrogen in soil varied profoundly before and after rabi seasons and the maximum available nitrogen was observed before rabi in those plots which supply 25% RDF through crop residues in kharif and 100% RDF through chemical fertilizers in rabi and 50% RDF through green manure in kharif and 100% RDF through chemical fertilizers in rabi. The physical properties like bulk density and water holding capacity were also significantly influenced by the treatments before and after the experiment in which lower bulk density values were exhibited by organics applied plots in kharif and they also showed significantly higher water holding capacity compared to those treatments which were supplied with organic matter in kharif . Soil chemical properties like organic carbon and CEC remarkably improved in organic manure applied plots along with inorganics in rabi. The population count studies of bacteria, fungi, and actinomycetes revealed the positive influence of the collective application of organic matter and inorganic fertilizers on soil biological properties and its subsequent influence on soil health when compared with control. As per the economic analysis of the cultivation the maximum benefit cost ratio was exhibited by the treatment which received 25% of RDF in kharif through crop residues and 75% of RDF through in organics in rabi .
