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.

Quick wilt disease of pepper (Piper nigrum Linn)-1 symptomatological studies on the quick wilt disease of pepper
(Department of Plant Pathology, College of Horticulture, Vellanikkara, 1978) Mammootty, K P; KAU; Abi Cheeran
The present study on the quick wilt disease of pepper caused by Phytophthora palmivora (Butler) Butler was conducted at the Pepper Research Station, Vellanikkara using Panniyoor-1 pepper variety. The objectives of the investigations were to study the symptoms of the disease and to find out suitable control measures using fungicides. The first visible symptom on leaf, stem and root was noticed 24 to 48 hours; two to five days and 24 to 48 hours respectively after inoculation, depending on the maturity of the plant part. A fully developed lesion had a dark brown hononecrotic centre and plesionecrotic boarder surrounded by yellow halo. The yellow halo was not noticed during prolonged wet and humid conditions. Under these conditions lesions was uniformly brown in colour. Zonations were noticed during the alternate wet and dry conditions. On the stem, branches and roots symptom usually developed as a uniformly brown and dark coloured lesions. Pathogen entered mainly though lower surface of the leaf. After infection, defoliation took place within five to ten days. Development of flaccidity, drooping and defoliation of the leaves were the marked symptoms during the progress of disease when the stem, branches or roots were infected. All the fungicides tested checked the growth of the fungus in vitro for a period of three days. The fungicides when sprayed or drenched two hours before inoculation completely checked the disease. However, there was mild infection on plant where Dithane M-45 was used for drenching the soil. As the interval between the fungicidal spray and inoculation prolonged there was progressive reduction in the control of the disease. None of the fungicides was able to eradicate completely the established pathogen on leaves. When fungicides were applied one day after inoculation there was complete control of the disease on stem. While the control was not complete when it was applied two days after inoculation. All the fungicides except Dithane M-45 completely checked the development of the disease when they were drenched in soil.

Studies on the control of bacterial wilt of tomato with reference to organic soil amendments and chemicals
(Department of Plant Pathology, College of Agriculture, Vellayani, 1977) Jayaprakash, M G; KAU; Rajan, K M
The pot culture and field experiments were conducted to assess the effort of organic soil amendments and chemicals on the incidence of bacterial wilt of tomato. The population dynamics in relation to the causal organism, total fungi, bacteria and actinomycetes were also studied. Theresult of the investigation revealed that organic materials did not chook the disease incidence to a satisfactory level . However , the application of organic material followed by the treatment with chlorotomycin and streptocycline gave a satisfactory control of the disease.

Studies on the effect of fungicides and silica in the control of sheath blight of rice caused by Corticium Sasakii (Shirai) Matsumoto
(Division of Plant Pathology, College of Agriculture, Vellayani, 1975) Mathai, G; KAU; Paily, P V
A field experiment to determine the effect of two fungicides under three levels of silica on the incidence and intensity of sheath blight of rice was conducted at the Agricultural College Farm, Vellayani during the crop season February to May 1974. The fungicides, hinosan and dithane M-45, were effective in reducing the intensity, per cent infection and rate of spread of the disease and thereby increasing the yield. Among the fungicides tried hinosan was significantly superior. Application of silica was found to have significant effect in reducing the intensity of the disease on the 75th day. However, the per cent infection, rate of spread and the intensity on the 85th day indicated that the effect of silica in imparting resistance to infection by the pathogen was not significant.

Studies on the leaf spot and post harvest diseases of banana, and their control
(Department of Plant Pathology, College of Agriculture, Vellayani, 1977) Suharban, M; KAU; Paily, P V
Varietal susceptibility of different cultivars to the leaf spot diseases of banana was studied in an existing plantation, consisting of 18 varieties in the Instructional Farm, Vellayani. It was found that Robusta and Chakkarakeli were the most susceptible while Venattumonthan and Mass being the least susceptible. Different types of leaf spots viz., Cordana leaf spot, Deightoniella leaf spot, Helminthosporium leaf spot, Septoria leaf spot and Cercospora leaf spot were studied, and the fungi associated with them were also isolated, Growth and sporulation of all these fungi were studied in different media. Power oil was observed to be the best fungicide eventhough there was no significant difference between power oil, Difolatan and Bavistin in the fungicidal control of leaf spot diseases. It was found that carbondioxide does not have any role in enhancing the keeping quality. Both partial filling and complete filling of the gas were seem to enhance deterioration. When higher concentrations of benomyl were tried it was found that 600 ppm was superior to all other treatmentsIn 500 gauge polythene bags. Eventhough different fungicides like Bordeaux mixture, benomyl and lime water were tried in different gauges of polythene bags viz., 150, 200, 250, 300, 350, 400, 450 and 500, 600 ppm benonyl in 200 gauge polythene bags was found to be the best in preserving the fruits followed by lime water, and Bordeaux mixture
