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.

    Statistical models for the assessment of yield loss due to weeds
    (Department of Agricultural Statistics, College of Horticulture, Velllanikkara, 2002) Priyalakshmi, M; KAU; Prabhakaran, P V
    A study was undertaken to identify suitable functional models for assessing the effect of weeds on the yields of three major crops of Kerala Viz. Rice, Tapioca and Sesame and to estimate the loss in yield in these crops caused -by the major weeds. The data required for the study were gathered from the available records of A.I.C.R.P on weed control . Multivariate techniques such as multiple linear regression analysis, step wise regression analysis and principal component analysis were used along with univariate techniques for the prediction of yield and yield loss. The study undoubtedly revealed the importance of weed in suppressing the potential yield of plants. The effect of weeds on crops depended on the type of management , crop and season. Crop loss estimates showed wide variation between seasons and locations. The estimate of loss ranged from 5.3% to 68.4% in rice, 3l.4% to 46.3% in sesame and '12.8% to 40.6% in tapioca. The percentage of avoidable loss' in different crops varied from 5.3% to 93.4%. Weed dry matter (W.D.M.) was found to be the most important weed character in , ' predicting crop yield and yield loss. Echinocloa was found to be one of the major weeds causing considerable havoc to rice crop. In general non linear mod~ls were more efficient than linear model in predicting crop yield. The cauchy function, reciprocal hyperbola, second order hyperbola and reciprocal straight line were adjudged to be the most prormsmg univariate functional models in des£ribing the yield-weed relation ship. Multivariate regression models were found to be more powerful in predicting crop yield than univariate models. In most of the cases the fitted statistical models described the proposed relation ship with satisfactorily high degree of precision.
