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.

    Development and perfomance evaluation of a tractor powered manure pulverizer cum application
    (Department of Farm Machinery and Power Enginnering, Kelappaji College of Agriculture Engineering, Tavanur, 2020) Sai Mohan, S; KAU; Jayan, P R
    Organic manures such as farm yard manure, green manure etc., when incorporated into the soil not only add nutrients but enriches the soil by the fixation of atmospheric nitrogen. Manures (FYM, vermicompost, edible oil cakes etc.,) are an important resources which provide nutrients that could reduce bagged fertilizer costs and improves the crop growth and performance. A well-managed manure is a valuable resource in providing nutrients for crop production. Use of farm yard manure and other organic manure is the way out to overcome the problems of soil degradation, loss of fertility and soil health. Manual application of manure consumes more time and labour. Therefore, the present study was undertaken to develop and evaluate the performance of a tractor powered manure pulverizer cum applicator. The components of the machine were developed to suit the various dosages of manure without much variation in the distribution efficiency. The actual field capacity and efficiency of manure pulverizer cum applicator was found out to be 0.311 ha h-1 and 86.5 % at a forward speed of 2.0 km h-1, 0.356 ha h-1 and 79.2 % at a forward speed of 2.5 km h-1 and 0.395 ha h-1 and 73.1 % at a forward speed of 3.0 km h-1. Maximum field capacity was noted at a traveling speed of 3.0 km h-1. A larger application rate of 1387.1 kg ha-1 for cow dung, 1624.4 kg ha-1 for goat faecal pellets and 1618.6 kg ha-1 for neem cake was noted at an engine rpm of 2500, forward speed of 2 km h-1 with a field capacity of 0.31 ha h-1. With increasing the forward speed to 2.5 and 3.0 km h-1, field capacity increases but the application rate is decreased. The cost of manure pulverizer cum applicator alone is Rs. 64,000. Cost of operation of manure pulverizer cum applicator as an attachment to tractor as explained in Section 3.4 was found as 583.05 Rs h-1 and 1943.5 Rs ha-1. Cost of manual manure application followed by manure pulverization was 582.7 Rs h-1 and 4662.2 Rs ha-1.
