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 of a machine vision system to identify matured pepper spikes
    (Department of Farm Machinery and Power Engineering, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 2021) Meera, T; KAU; Sindhu, Bhaskar
    Black pepper is a perennial crop and one of the most economically significant spices in India. It has a high commercial value in the market all around the world. Its fruit is harvested, dried and powdered for many cuisines and processed for many value added products. Black pepper is a flowering vine growing up to 4 m in height. The berries turns from green to red on maturity and are harvested when it starts to turn red. For achieving good quality and good sized pepper, it should be harvested at its proper matured state. Farmers for their time saving and due to heavy work intensity, harvest almost all the fruits which are in a range of maturity along with the real matured ones. This eventually affects the crop yield and quality. Hence employing an automated identification system in this case would be effective. An application programme interface was developed for this, using the fruit features like the shape, colour and size. By using the machine learning techniques and computer vision technology, two programmes were developed in python language, one using OpenCV library and Haar Cascade classifier, and other platform with TensorFlow as library and faster-RCNN as classifier. Studies were also carried out to analyse the physical properties of black pepper. Using image acquisition, a dataset was created and was used for training and preparation of both the models. The hardware part of the system comprised of a webcam as sensor, Raspberry Pi processor, a RPI display unit and some accessory parts. The hardware and software parts were installed and assembled, and subjected to performance evaluation. It was revealed that the Tf-RCNN platform had better performance and efficiency. The performance evaluation parameters viz., sensitivity, specificity and accuracy values were 78%, 71% and 75% respectively for the second model. It was statistically verified that there is a significant difference between the two platforms and the second model had better consistency.
