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.

    Influence of different levels of energy on growth performance of crossbred pigs
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 2001) Rekha, P; KAU; George, Mathen
    An experiment was conducted to assess •the influence of different levels of energy on the growth performance of crossbred (Large White Yorkshire x Desi) pigs. Fifteen male (castrated) and fifteen female weaned crossbred piglets with an average body weight of 12.9 kg were divided into three equal groups as uniformly as possible with regard to age, sex and body weight. The three groups of piglets were maintained on three rations with 16 per cent crude protein but differing in their energy content, viz., 2800 kcal (T1), 3000 kcal CT2) and 3200 kcal (TI) of digestible energy (DE) per kg. The average daily gains recorded for the three groups T1, T2 and TI were 262.9, 302.0 and 362.8 g respectively. The cumulative feed conversion efficiencies were 6.0, 5.2 and 4.1 for the groups T1, T2 and TI respectively. The values recorded for TI were higher (P<0.01) than those for T1 and T2. The digestibility coefficients of nutrients except that of crude fibre and crude protein were found to improve with increase in the energy content of the rations. Study of the carcass traits revealed that the body weight at slaughter and dressed weight without head improved as the energy content of the rations increased. However, dressing percentage, carcass length and back fat thickness were not significantly influenced by the energy content of the ration. The cost of feed per kg weight gain of animals was significantly lower (P<0.01) for the dietary treatment T3 compared to that of T2 and Tl, the values being Rs.49.90, 43.30 and 34.10 for Tl, T2 and T3 respectively. The above results indicate that crossbred pigs require 3200 kcal of DE/kg of the ration for better growth performance provided the crude protein level is maintained at 16 per cent.

    Investigations on etio-pathology of vomiting in dogs
    (Department of Clinical Medicine, College of Veterinary and Animal Sciences, Mannuthy, 2001) Muraly, P; KAU; Baby, P G
    The study "INVESTIGATIONS ON ETIO-PATHOLOGY OF VOMITING IN DOGS" was conducted in 20 dogs to evaluate ultrasonography and radiography as diagnostic tools in vomiting dogs; to assess hydration status, electrolyte and acid-base balance in vomiting dogs and to correlate clinico-pathologic findings with radiographic and ultrasonographic changes. Various parameters such as history, physical examination, hydration status, ultrasonography, radiography-plain and contrast, haematology, serum biochemistry, and wherever possible histopathology were studied. Most of the dogs under study had bile stained watery vomitus but dogs with pyloric stenosis had frothy or watery white vomitus. The frequency of vomiting in dogs with gastritis and gastrointestinal (GI) obstruction was two to seven times per day, it was variable in dogs with hepatic and renal disorders, but was associated with food intake in dogs with pyloric stenosis. Physical examination was found useful in dogs with GI obstruction, while it was non-specific in dogs with gastritis and renal disorders. Capillary refill time (CRT) and degree of sunken eye balls were helpful to assess dehydration. Estimation of volume of packed red cells (VPRC) was found beneficial to assess dehydration unless the dogs are anemic. Ultrasonography could not identify any lesions in dogs with gastritis, but was useful to detect GI obstructions due to pyloric stenosis, intussusception and foreign body and to characterise lesions in the parenchymal organs like liver and kidney. While plain radiographs could give indication to possible non-radiopaque GI obstructions, contrast radiography was required to confirm. Radiography could not identify any lesions in dogs with gastritis, hepatic and chronic intestitial nephritis. Hypokalemia with metabolic alkalosis was the significant electrolyte and acid-base derangement in dogs with vomiting due to gastritis and GI obstructions.

    Bionomics and ecological management of coconut eriophyid mite
    (Department of Agricultural Entomology, College of Horticulture, Vellanikkara, 2001) Vidya, CV; KAU; Ranjith, A M
    The bionomics and ecological management of coconut eriophyid mite, Aceria guerreronis (Keifer) was studied under the Department of Entomology, College of Horticulture, Vellanikkara. The preference of mites to bunches of different maturity, symptoms of damage, population dynamics, relationship of mite population with weather factors and the distribution pattern of mites based on plant morphology were considered for the study. Some ecological management practices were also tried along with this. The experiment was laid out as completely randomised design. Mites were absent in male and female flowers and also on buttons of first bunch. Initiation of infestation starts from buttons of second bunch and population increases further and maximum population is noticed in buttons of third and fourth bunches and thereafter it decreases. This is because after fourth bunch, the meristematic tissue becomes necrotic due to feeding of mites and hence mites cannot feed further easily. Traces of population were noticed even on nuts of ninth bunch. Predatory mites were also seen along with eriophyid mites even though they are very negligible. Symptoms of damage were seen outside from second bunch onwards. The symptom initially appears as whitish streak or triangular patch and it increases further in length and breadth and becomes brownish and later necrotic. In some cases, cracks, cuts and gummosis can be seen on the husk. The relationship between surface damage and mite population was worked out. Maximum mite population was noticed when the surface damage was 1-3 and 3-6 cm2 before and after the removal of perianth respectively and the percentage of damage was 1-3 per cent. Mite population was found to vary with different weather parameters. Minimum temperature of current week, current, -1 and -2 fortnights and maximum temperature of -2 fortnight were positively related with mite population. Morning humidity is also positively related with mite population. Mite population was negatively related with wind speed of zero current, current, -I and -2 fortnights. There is no direct relation between mite population and rainfall, number of rainy days, evening humidity and sunshine hours. Mite infestation was irrespective of the height of the palm, crown shape and perianth arrangement. The intensity of infestation varies between each inner tepals. Maximum infestation was under fourth tepal followed by fifth and sixth tepa\. The preference of mites to different portions under each tepal also varies with maximum entry through the 'outer edge' of fourth tepal followed by 'outer edge' of fifth tepal, 'middle' portion of sixth tepal, 'middle' portion of fifth and fourth tepal, and 'inner edge' of sixth and fifth tepa\. Infestation was found to be less in round shaped nuts compared to oval and oblong nuts. Maximum incidence was in green coloured nuts followed by greenish yellow and orange coloured nuts. There was no reduction in mite damage by different water regimes (rainfed, channel and drip irrigated) fertilizer regimes (0.34:0.17:0.68 kg NPK/palm, 0.5:0.32:1.2 kg NPKlpalm and 0.25:0.32:1.2 kg NPKlpalm) micronutrients (MgS04, ZnS04, MnS04, Borax and Micronutrient mixture) and crown cleaning (once and twice in an year).

    Integrated nutrient management in hedge lucerne (Desmanthus virgatus(L.)willed) under rainfed condition
    (Department of Agronomy, College of Agriculture, Vellayani, 2001) Kavitha, G V; KAU; Lakshmi, S
    A field experiment was conducted at the Instructional Farm, College of Agriculture, Vellayani, Thiruvananthapuram, Kerala State to find out an integrated nutrient management technique for Desmanthus virgatus (L.) Willd. under rainfed condition. The influence of chemical fertilizers and biofertilizers on growth parameters, fodder yield, quality of produce, uptake of nutrients, chemical properties of soil and economics was investigated. Three levels of nitrogen (0, 15, 30 kg N ha"), three levels of potassium (0, 20, 40 kg ha") and biofertilizers (Rhizobium, AMF and Rhizobium + AMF) were combined to form twenty seven treatment combinations. The experiment was laid out in split plot design with three replications. Results of the experiment revealed that the chemical fertilizers as well as bioinoculants had significant positive influence on improving the fodder production potential of Desmanthus virgatus. Application of inorganic fertilizers and eo- inoculation of hedge lucerne with Rhizobium and AMF significantly increased the growth parameters namely plant height, length of branches, number of branches and leaf: stem ratio. Highest dose of chemical fertilizers and dual inoculation with biofertilizers registered maximum green fodder yield in all four harvests. Similar results were obtained in the case of dry fodder yield also. Quality parameters of the forage significantly improved as a result of dual inoculation with biofertilizers. Maximum crude protein content was realized with application of highest dose of nitrogen and potassium. The nutrient uptake showed a significant increase with increase in doses of chemical fertilizers. Dual inoculation of biofertilizers significantly increased the uptake of nitrogen, phosphorus and potassium. Combined application of biofertilizers improved the nitrogen and phosphorus status of the soil after the experiment. Highest dose of nitrogen gave the highest soil nitrogen content. Similarly highest dose of potassium recorded highest soil potassium content after the experiment. The physical and economic optimum dose of nitrogen for Desmanthus virgatus was 32 kg ha-I and 31 kg ha-I respectively while that of potassium was 22 kg ha-I, The use of chemical fertilizers and dual inoculation with biofertilizers recorded highest net returns and benefit: cost ratio, emphasizing the need for an integrated approach in nutrient management.
