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.

    Crop weather relationship in okra
    (Department of Agricultural Meteorology, College of Horticulture, Vellanikkara, 1999) Kavitha, S; KAU; Kesava Rao, A V R
    CROP WEATHER RELATIONSllP IN OKRA (Abelmoschus esculentus [L.} Moench), VARIETY 'ARKA ANAMIKA' The experiment was conducted during 1998-1999 at the College of Horticulture, Vellanikkara to find out the crop weather relationships of okra, 'Arka Anamika'. The experiment was laid out in randomised block design with three replications. The treatments consisted of twelve monthly sowing, starting from 21 st April 1998 to 21 st March 1999. Observations on morphological, phenological and yield attributes were recorded during the course of investigation. The daily values of weather elements viz., rainfall, number of rainy days, maximum and minimum surface air temperatures. bright sunshine, mormng and afternoon relative humidity, pan evaporation and wind speed were collected from the Principal Agricultural Meteorological Station, College of Horticulture, Vellanikkara, to work out the crop weather relationships of okra. March, April and September sown crops were significantly superior in terms of fruit yield per plant, number of harvests and crop duration. April sown crop was also superior in plant height, number of nodes on mainstem, and number of primary branches. The fruit yield was significantly associated with the plant height, number of nodes on main stem, number of primary branches, number of harvests and duration of the crop. A multiple regression equation was worked out for predicting fruit yield based on plant characters and it is as follows: Y = 3.08 XI + 11.15 X2 - 210.14 (R2 = 0.94) Where, XI is the duration of the erop in days, X2 is the number of harvests and Y is the yield per plant (g). Based on the association between weather elements and crop yield of okra, a multiple regression equation was worked out and given below: Y = 50.7 XI - 28.69 X2 + 16.11 X3 - 0.058 X4 - 456.29 (R2 = 0.76) Where, Y = yield per plant (g), X, - Minimum temperature (OC) during vegetative phase (6,h to 7th week after sowing), X2 - Maximum temperature (OC) during reproductive phase (6th to 9th week after sowing), X3 - Bright sunshine (h per day) during vegetative phase (4th to 6th week after sowing) and X.4 - Rainfall (mm) during vegetative phase (5th to 6th week after sowing).
