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.

    Standardization of organic nutrient regimes for Anthurium (Anthurium andreanum Lind.) cultivars.
    (Department of Pomology and Floriculture,College of Agriculture, Vellayani, 2011) Jomy, Jacob; KAU; Sabina George, T
    Anthurium andreanum Lind. is cultivated globally for its attractive flowers and foliage. Kerala is identified as one of the most suitable places for growing Anthuriums because of the congenial climatic conditions similar to its natural habitat. For the nutrition of Anthuriums, standardization of eco-friendly organic manures is a felt need of growers. Though several organic nutrient dosages and an integrated nutrient dosage have been found promising for juvenile to mature tissue cultured plants of the Anthurium, these differed in their content of nutrients, constituent organic-inorganic fractions, components and their frequency of application. Refinement of these dosages and formulation of modified organic nutrient regimes consisting of easily available and eco friendly cost effective organic materials were intended in this investigation. Thus, an investigation was conducted at the Department of Pomology and Floriculture, College of Agriculture, Vellayani of the Kerala Agricultural University during 2009-2011 for a period of 18 months. The experiment was in CRD with 12 treatment combinations of 2 cultivars ( Anthurium andreanum cv. Acropolis and cv. Tropical) and 6 nutrient regimes The nutrient supplied under N1 to N4 was 2.15: 1.47: 2.37 N:P2O5:K2O g plant-1 (total per bimonth), and under N5 and N6 was 2.41:4.73:1.89 N:P2O5:K2O g plant-1 (total per bimonth)]. All the treatments were given weekly application of cow dung slurry 0.83 g/ plant. N1 comprised of organic manure mix 12.4 g plant-1 applied weekly (containing coir pith compost, bone meal, neem cake and wood ash) + Cow’s urine 8 ml/plant weekly. Modified organic manure mix 25.96 g plant-1 (containing wood ash, cow dung and bone meal) applied weekly for N2, 51.925 g plant-1 applied biweekly for N3, 103.85 g plant-1 applied monthly for (N4). N5 comprised of organic manure mix 40 g plant-1applied bimonthly (containing leaf compost, coir pith compost, bone meal, neem cake, poultry manure and wood ash) +NPK Fertilizer (18:18:18) @1 g plant-1 weekly. N6 comprised of organic manure mix 40 g plant-1 applied bimonthly (containing leaf compost, coir pith compost, bone meal, neem cake, poultry manure and wood ash) + Organic manure mix (containing cow dung, leaf compost, bone meal, and wood ash ) applied weekly. The first experiment was aimed at standardizing organic nutrient regimes for flower production from top cuttings in Anthurium andreanum cv. Acropolis and cv. Tropical. Vegetative characters such as the total number of newly emerged leaves upto 6, 12 and 18 MAP, annual leaf production, total leaf area at 6, 12 and 18 MAP, mean petiole length at 6, 12 and 18 MAP, mean phyllochron, days from emergence to senescence of leaves, rate of sucker production were found to differ significantly among manurial treatments. A comparative enhancement in vegetative characters such as number of leaves, leaf area, petiole length, annual leaf production and leaf duration, and lesser interval between leaf emergence were observed in plants under N2, N3, N4 and N6. These treatments also recorded greater number of flowers as well as annual flower production per plant, shorter mean interval between flower emergence and lesser days to harvestable maturity of flowers than organic treatment with cows urine weekly (N1) and organic inorganic integrated regime (N5). The manurial treatments of modified organic treatment applied biweekly (N3), monthly (N4) and organic treatment with manure mix bimonthly (N6) increased the length and width of the spathe, greater girth of flower stalk. The vase life of flower were found greater under modified organic treatment weekly (N2), biweekly (N3) and organic treatment with cows urine weekly (N1). Similarly, water uptake was higher in plants treated with modified organic treatment applied biweekly and weekly than under organic inorganic integrated regime. The organic inorganic integrated regime was found to effect in higher N and P content of leaves than all other treatments. Higher K content of leaves was recorded under N3 regime. The second experiment was aimed at standardization of nutrient regime(s) for sucker production and subsequent flower production from basal stem stumps in Anthurium andreanum cv. Acropolis and cv. Tropical. Modified organic treatment applied weekly (N2), biweekly (N3) and monthly (N4) recorded greater total leaf area of shoots from 3 MAP until separation, number and length of roots at separation, total length of suckers and number of leaves at retention and thereafter, lesser interval between leaf emergence and greater longevity of leaves and greater petiole length at 18 MAP, length, number of leaves and mean petiole length of retained suckers at 18 MAP, earlier and greater flower production. Modified organic treatment applied biweekly (N3) also recorded higher total number of suckers and rate of sucker production. Cultivar differences in vegetative and floral characters were found to be distinct in both experiments. In the planted basal stumps of experiment 2, sprouting and sucker development was observed. However, earlier sprouting and development of sprouts into shoots was observed in cv. Tropical than in Acropolis. In Experiment 1, though the treatments N2, N3 and N4 had equal effects on leaf production, total leaf area, flower production and shorter interval between flower emergence, in economic analysis, the treatment expenditure increasing from N4 to N2 can be a limiting factor determining their relative feasibility. The advantages in suckering observed in these cultivars in experiment 2, resulted in greater net value realization of cv. Acropolis under modified organic treatment applied biweekly (N3) and monthly (N4) and in cv. Tropical under modified organic treatment applied biweekly (N3).
