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.

    Investigations on nuclear polyhedrosis of black hairy caterpillar, Pericallia Ricini fabricius (Arctiidae: Lepidoptera)
    (Division of Entomology, College of Agriculture, Vellayani, 1975) Vasudevan Nair, K P; KAU; Abraham Jacob
    Detailed investigations were carried out on the nuclear polyhedrosis of the black hairy caterpillar,Pericallia ricini (Arotiidae) covering symptomatology, larval susceptibility, effect of the virus on the larval moulting, changes in the number of circulating haemocytes in the infected larvae, nature of causative agent, effect of temperature and sunlight on the infectivity of the virus and the cross infectivity of the virus to other species of lepidoptera. The virus infected larvae exhibited a ll the typical symptoms of nuclear polyhedrosis infection as reported from other lepidopterous larvae. The larvae infected in the early instars appeared paler and thinner. The infected larvae showed loss of appetite and became sluggish. The dead or dying larvae showed the characteristic symptom of hanging head downwards from the top o f the containers with the aid of prolegs. In the advanced stages of infection the cuticle became fragile and it ruptured liberating the liquefied body contents. The susceptibility of the larvae to virus infection decreased with increase in the age of the larvae. The averageincubation period varied from 5*24 days for the second instar to 8 days for the sixth instar larvae. The virus infection inhibited moulting in the later stages of the disease. No significant difference was observed in the THC of healthy larvae and virus infected larvae up to 24 hours after inoculation; there was significant reduction in the THC of diseased larvae after 24 hours of inoculation.

    Studies on the effects of juvenile hormone analogues on the development of Spodoptera mauritia (Boisduval) (Lepidoptera : Noctuidae)
    (Department of Entomology, College of Agriculture, Vellayani, 1975) Krishnadas, V S; KAU; Jhonson, J
    Morphogenetic effects of two juvenile hormone analogues viz. altosid and farnesyl methyl ether (FME) on spodoptera mauritia were studied under laboratory conditions. Ovicidal action was first tested by using different concentrations of juvenile hormone analogues diluted in pure acetone. All the treatments and control (acetone treatment) prevented embryonic development to varying degrees. Since the solvent also caused mortality in eggs, one per cent acetone solution in water was used in later experiments. Treatments ranging from 0.0125 to 0.1 per cent altosid resulted in egg mortality ranging between 40 to 60 per cent . The corresponding mortality figures caused by FME were 36 and 52 per cent, the values were comparatively less than those with altosid. Freshly moulted last larval instar was the most susceptyible stage to the action of JHA’s. All the hormonal concentrations used in the study affected normal metamorphosis and moulting. Some of the treated larvae moulted into supernumerary larval instars and larval pupal mosaid. Prolonged larval duration, failure of normal moulting altered body pigmentation, reduction in water content of the excreta and slight swelling of the thoracic legs and prolegs were also recorded as hormonal effects on the last instar larvae. Higher dosages of FME had direct toxicity to the larvae. Pupae were more susceptible to the action of altosid than of FME. Metamorphosis was completely inhibited at all doses used. All the treated pupae showed darker colouration than control pupae. Altosid and FME had effects on fecundity, embryogenesis and latent effect on post embryonic development when the female moths were treated. Reduction of fecundity upto 36 per cent was recorded by 10 µg per µl of both the hormonal analogues used in the experiment. A sizable number of eggs failed to hatch since the embryonic larval differentiation was seriously affected. The progeny of the treated females suffered heavy latent mortality especially in the first larval instar stage. The average adult longevity of the treated moths increased significantly. There was only a marginal increase in the time for laying the first batch of eggs in treated moths. In general altosid was found to be superior to FME in producing morphogenetic effects on spodoptera mauritia.

    Studies on the chemical control and insect-plant relationships of the rice leafroller, Cnaphalocrocis Medinalis Guenee (Pyraustidae:Lepidoptera)
    (Division of Entomology, College of Agriculture, Vellayani, 1975) Mohandas, N; KAU; Gopalakrishnan Nair, M R
    The series of laboratory and field experiments were conducted to study the relative toxicity of 24 insecticides to noths and larvae of the rice leaf roller, cnaphalocreoois medinalis the relative effiency of these insecticides in controlling the pest in the field and the insect plant relationships between c.medinalis and different rice varieties. Suitable methods for the collection of moths of c.mdinalis from the field for the collection of their eggs and first instar larvae in sufficiently large numbers and for rearing the insect in the laboratory were eveloved.
