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 evaluation of a low cost power operated paddy thresher-cum-winnower
    (Department of Farm Power Machinery and Energy, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 1996) Sureshkumar, P K; KAU; Sankaranarayanan, M R
    Since threshing is labour intensive and involves considerable human drudgery and as the threshers now available are not suitable for small and marginal farmers, a Low Cost Power Operated Paddy Thresher Cum Winnower has been developed and tested. The machine consists of a threshing unit of wire loop cylinder and cover, a winnowing unit, a grain collecting tray, prime mover, power transmission system and the main frame. The power required to operate the machine is taken from a 2 hp electric motor and is transmitted to the cylinder and blower shafts by V- belt and pulley arrangement. Two labourers can hold the crop against the threshing cylinder. The optimum cylinder speed is 400 rpm. The capacity of the thresher at 16.0 per cent moisture content of the crop is 300 hg per hour. Threshing and cleaning efficiencies are 99.25 and 91.82 per cent respectively. Mechanical damage to the grain is negligible. The labour requirement of the thresher cum winnower is two. The cost of the thresher cum winnower was found out to be around Rs 8000.00 and the cost of operation for threshing and winnowing was Rs 8.50 per quintal. An empirical relation between the energy requirement of the thresher and various crop and thresher parameters is P = 931.035 + 4.683 (MC) – 0.462 (PV) – 1.169 (FR) + 8.251 (G/S ratio) The moisture content of the crop and the Feed Rate have statistically significant effect on power Requirement whereas the cylinder speed and Grain/Straw ratio do not have any statistically significant effect.

    Development of a power tiller operated paddy transplanter for conventional seedlings
    (Department of Farm Power Machinery and Energy, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 1995) Prakash, K V; KAU; Sivaswami, M
    Transplanting of paddy seedlings is a very tiresome and labour consuming operation and labour shortage is experienced during planting. As a solution to reduce the high cost of cultivation and labour shortage in paddy transplanting, a power tiller operated paddy transplanter is an essential need of hour. The APAU paddy transplanter was evaluated after rectifying the defects at KCAET instructional farm, Tavanur. Based on the field experiences and considering the all problems in APAU paddy transplanter, an improved version of power tiller operated paddy transplanter was developed and fabricated at KCAET Tavanur and tested during September-October 1994. The convensional root washed paddy seedlings ready to manual transplanting were used. When the power tiller is operated at a forward speed of 1.20 km per hr, the transplanter could transplant 2 to 4 seedlings per hill at a spacing of 100 to 120 mm. The average field capacity was found to be 0.13 ha per hr. A saving of Rs.800 per ha which is 50 per cent and reduction of 296 man-hr per ha which is 92.5 per cent was achieved for transplanting operation alone compared to manual transplanting.

    Design fabrication and testing of a cashewnut decorticator
    (Department of Farm Power Machinery and Energy, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 1993) Joby Bastian; KAU; Jippu Jacob
    A manually operated cashewnut decorticator is designed, developed and evaluated. The major parts are top blade assembly, and linkage assembly, 2-blade bottom assembly, and linkage assembly. The whole assembly is fixed on a work table. The steamed cashewnut is placed manually between the top and bottom blades. Upon pressing the pedal the top and bottom blades slit the two long sides of the nut. The two bottom blades are then opened wide with a cam splitting open the shell in to two halves. The kernel is released from the shell. The efficiency in decorticating is 88 per cent while the percentage of the number of kernels damaged is 12. The capacity of the machine is 900 nuts/h. The important physical properties of nuts were also studied. It is kidney shaped. Its mean size is 32.40 mm long, 24.60 mm wide and 17.60mm thick. The average kernel size is 26.00 mm long, 17.20 mm wide and 12 mm thick. The average thickness of the shell is 3.20 mm. The average weight of the nut is 7.0 g while that of the kernel is 2.1 g. considering its performance the mechanism is sound. It is recommended for further studies and modifications.
