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.

    Studies on heterosis and combining abilities with respect to important economic traits in Capsicum annuum, L.
    (Division of Agricultural Botany, College of Agriculture, Vellayani, 1981) Manikantan Nair, P; KAU; Mary, K George
    Sixty three varieties of Capsicum annuum representing different agroclimatic regions of the country constituted the base material of the study. Based on yield potential , adaptability and tolerance to leaf curl complex disease, thirty varieties were selected for subsequent studies. Comprehensive genetic studies including estimation of genetic parameters, cause effect relationship by path coefficient analysis, genetic divergence by Mahalanoble D2 statistic and a nine parent diallel analysis to causes the combining ability, to unravel the pattern of inheritance and also to examine the level of heterosis manifested with respect to eighteen economic characters including four nutritiveand quality attributes namely Vitamin A, Vitamin C, Capsaicin and Oleoresin content were conducted during the year 1976-79. Analysis of plot means exhibited highly significant differences among varieties except for Capsaicin content. The high degres of variability in economic attributes offers scope for recombining desirable genes from different varieties.

    Biometric analysis of yield and certain yield attributes in the para rubber tree: Hevea Brasiliensis Muell. Arg.
    (Department of Agricultural Botany, College of Agriculture, Vellayani, 1984) Markose, V C; KAU; Mary, K George
    The para rubber tree, Hevea brasiliensis, is the commercial source of natural rubber. Introduced into the Far East in 1876, from Brazil, commercial cultivation started in India during 1902. The tree has a gestation period of six to seven years. A large number of clones have been evolved through ortet selection and through hybridisation, which show variability for different characters. The present study was undertaken to estimate (1) productivity (2) yield pattern (3) variability (4) correlations (5) effect of yield attributes (6) genetic diversity of twenty clones, and (7) early growth vigour of open pollinated seedlings of selected clones.

    Genetic studies in red gram (Cajanus cajan L.)
    (1988) Radhakrishnan, V V
    The research project “Genetic studies in red gram (Csjsnus csjsn h. Mill sp.)* wae carried out at the College of Horticulture, Kerala Agricultural University, Vellanikkara, Trichur during the period 1983-86. The genetic diversity studies among the 112 genotypes of red grans obtained from NBPGR, Vellanikkera and THAU, Coimbatore during 1963-84 showed that the genotypes of the same place of origin fell into different clusters while those of diversified origin fell into seme cluster. All the genotypes studied were grouped into five clusters. Based on both the inter and intr©cluster distances 20 genotypes representing the broad spectrum of variability were selected and raised during 1965-86. The values estimated for phenotypic coefficient of variation and genotypic coefficient of variation showed that number of clusters per plant, number of pods per plant and seed yield possessed high estimates. Number of days from sowing to 50 per cent flowering and seed yield have exhibited high heritabllity coupled with moderately high genetic gain estimate* indicating the involvement of additive gene effect* Ku:ber of days from sowing to harvest and height of plant at harvest, have high or moderately high estimates of heritability together with low values of genetic gain indicating the action of non-additive genes. In nine out of ten cases there has been significant positive correlation between component characters and seed yield both in the phenotypic and genotypic levels, however the correlation of hundred seed weight with seed yield was not significant both at phenotypic and genotypic levels* Intercorrelaticna studies have shown that characters exhibiting significant association with seed yield per plant were also highly intercorrelated indicating that these characters can be simultaneously improved. Path coefficient analysis showed that number of poda par plant, hundred seed weight, number of primary branches at harvest, number of secondary branches at harvest and length of pod bearing branches had high positive direct effects on seed yield in th at order* The residual effect wea 0*07227 indicating that about 93 per cent of the variation in yield were contributed by the ten components considered in path coefficient analysis. The selection index formulated with characters like seed yield, number of pods per plant and hundred seed weight showed an efficiency of 8.4 per cent over direct selection and it includes 57 per cent of the factors determining the yield. Hence it is suggested for isolating superior genotypes. A comparison of different genotypes based on the index value has revealed the superiority of the genotypes NSPGR-XX-EC—10046-1 and HBPGR-124-PLA-345-1 over others. The study paved the way for understanding the source of variability for various factors contributing to yield, the degree of diversity among the genotypes, on the association between yield and its components and between themselves, and helped to formulate selection index for selecting superior genotypes.
