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.

    Response of banana Musa (AAB) 'Nendran' to nutrient sources
    (Department of Fruit Science, College of Agriculture ,Vellanikkara, 2021) Manohar Lal Meghwal.; Jyothi, M L; KAU
    anana is the leading tropical fruit in the world market today with a highly organized and developed industry. Banana having a root system spread in the top 60 cm soil, is heavy feeder of nutrients and requires large quantities of nutrients for its growth, development and yield. Nutrient removal from soil by crops must be replenished. Under good management conditions and adequate supply of biofertilizers and organic manures, the nutrient removal can be replenished and soil physical, chemical and biological properties can be improved. Organic and inorganic sources of nutrients have significant influence on fruit quality and soil characteristics. The current agricultural policy emphasize a shift towards safe agricultural practices for which organic management is the best option. However the crop behaviour under organic and inorganic management needs elaborate studies. Hence the research entitled ‘Response of banana Musa (AAB) 'Nendran' to nutrient sources was formulated to elucidate response of banana in terms of growth, yield and quality to nutrient sources and to compare the fruit quality of banana grown under organic and conventional systems in farmer’s field. The study revealed that vegetative growth of Musa Nendran banana was not influenced by different sources of nutrients in early stage in both the years but later differences were recorded between the treatments. Plant height, number of leaves and pseudostem girth showed significant differences from 90 DAP. At bunching stage plant height and pseudostem girth were higher in organic treatments. There was significant difference in pseudostem girth between the treatments throughout the growth stage of Nendran banana. Among the treatments, T8 resulted in better growth of plants. Leaf characters like number of leaves and leaf area index were not influenced significantly between organic and integrated nutrient management. Early leaf production was also noticed in treatment T8 as indicated by the observations on phyllocron. Growth was delayed in control where no manures and fertilizers. In general more number of leaves per plant and lesser duration for leaf emergence was recorded in both the years in organic treatments. Chlorophyll production in the index leaf of banana was influenced with organic and inorganic nutrition. Chlorophyll a, b and total chlorophyll in the index leaf were distinctly higher in treatment T8 (fertigation with FYM) which was on par with treatments T3 and T5 where organic manures alone were applied. Early flowering and early harvesting were observed in organic treatments. Higher total biomass production was recorded in organic treatments. Yield and yield attributing characters like bunch weight, number of finger, finger weight were highest in treatments with organic sources of nutrients. The mean bunch weight was influenced significantly by organic and inorganic sources of nutrients. Fertigation with organic sources of nutrients resulted in the production of heavier bunches in both years. Maximum bunch weight was recorded from treatment T8 which was on par with other organic treatments as well as integrated management with fertilisers applied as fertigation as well as based on soil test results. No significant variation was observed between treatments on number of hands per bunch and finger characters like finger length and girth. Peel thickness of fruits were not significantly influenced but the pulp to peel ratio was significantly influenced by the treatments. Pulp to peel ratio was higher in all treatments other than T1 and control where T1 is the POP recommendation for TC banana under integrated nutrient management. Yield per plant was positively correlated with available N, P, K, Calcium, magnesium, sulphur, Zn, Cu, B, content of the soil. Yield was also positively correlated with soil properties like pH, organic carbon content, CEC, Bulk density, and Dehydrogenase enzyme activity. Higher biomass production was recorded in plants that received nutrients from organic sources compared to integrated nutrient management and control. Shelf life of fruits were improved in organic treatments. Fruit quality parameters like TSS, Total sugars, ascorbic acid and β carotene of ripe banana fruits were improved in organic treatments compare to inorganic system. Sensory score of ripe fruits and fruit chips were maximum in organic treatments. The taste of ripe banana fruits was improved in plants grown under organic treatments. Fertigation with organic manures (T8) resulted in improved fruit quality of Nendran banana in both the years. Different soil physical and chemical properties also improved when nutrients were supplied through organic sources. Soil pH, electrical conductivity, organic carbon content, cation exchange capacity, available, N, P, K, Mg, Iron, Copper, Zinc, Mn and boron were better in soils receiving organic manures alone. Similarly the soil biological properties like dehydrogenase activity, nitrogenase activity, microbial biomass carbon, and viable counts of total fungi, bacteria and actinomycetes were better in organic treatments. Bulk density of soil was low in soils receiving organic manures alone compared to integrated nutrients. Total uptake of nutrients in organic and integrated nutrient management system was compared. Uptake of N, Ca, S, Fe, Mn, Zn and Cu was higher in organic system of cultivation of banana compared to integrated system. Higher benefit cost ratio was recorded banana grown in organic system. The study revealed that organic sources of nutrients improved soil properties and thereby improved growth, yield and quality of banana.
