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.

    Performance of greengram (vigna radiata( L.) wilczek) cultivars under different tillage methods
    (Department of Agronomy College of Horticulture, Vellanikkara, 2018) Abid, V; KAU; Bindhu, J S
    An experiment entitled “Performance of greengram (Vigna radiata (L.) Wilczek) cultivars under different tillage methods” was undertaken to study the response of selected greengram cultivars under different tillage methods and to identify the most economical combination of cultivar and tillage. The experiment was conducted during the period from December 2017 to March 2018 at Agronomy Farm, College of Horticulture, Vellanikkara. Split plot design was adopted with three replications. The main plot treatments were four tillage methods viz., M1 - minimum tillage (primary tillage only), M2 - minimum tillage followed by pre-emergence application of pendimethalin @ 1 kg ha-1, M3 - minimum tillage followed by post-emergence application of imazethapyr + imazamox @ 80 g ha-1 at 20 DAS and M4 - conventional tillage (Primary and secondary tillage) followed by two hand weedings at 15 and 30 DAS. Sub plot treatments were four cultivars; V1 –CO 6, V2 –CO 7, V3 –CO 8 and V4 -VBN (Gg)2. The growth attributes of greengram (plant height, number of branches and leaf area) at flowering and at harvest stages were influenced by tillage methods. Higher values were observed in minimum tillage followed by application of herbicide imazethapyr + imazamox @ 80 g ha-1 at 20 DAS and the lowest in minimum tillage. Among the cultivars, CO 8 and VBN (Gg)2 had recorded higher growth parameters. The physiological parameters, CGR, LAI, LAD and number of nodules per plant also varied with tillage methods and cultivars. The results revealed that yield parameters as well as yield were influenced by tillage methods and cultivars. Minimum tillage followed by application of imazethapyr + imazamox @ 80 g ha-1 at 20 DAS resulted in higher number of pods and number of seeds per pod and was at par with conventional tillage method. Among the cultivars, higher values of yield components were recorded in CO 8 followed by VBN (Gg)2. Minimum tillage followed by application of imazethapyr + imazamox @ 80 g ha-1 at 20 DAS recorded higher seed yield (748 kg ha-1) which was at par with conventional tillage. This was 102 per cent higher than yield from minimum tillage. The cultivar CO 8 recorded the highest seed yield (736 kg ha-1) and differed significantly from other three cultivars. All cultivars performed better under minimum tillage followed by application of imazethapyr + imazamox @ 80 g ha-1 at 20 DAS and conventional tillage followed by two hand weedings at 15 and 30 DAS. Among the interactions, the cultivar CO 8 in minimum tillage followed by imazethapyr + imazamox @ 80 g ha-1 recorded higher seed yield (942 kg ha-1) and it was at par with conventional tillage. The results revealed that weed density and dry weight varied with tillage methods but not with cultivars. The weed density was lower in conventional tillage method which was at par with minimum tillage followed by herbicide sprays. The soil nutrient status was not influenced by the cultivars. Among the tillage methods, minimum tillage method recorded higher values of available nitrogen, phosphorus and potassium after the experiment. The nutrient uptake was higher in minimum tillage followed by post emergence application of imazethapyr + imazamox @ 80 g ha-1 at 20 DAS. Economic analysis revealed that cultivar CO 8 grown under minimum tillage followed by imazethapyr + imazamox @ 80 g ha-1 at 20 DAS (M3V3) recorded the highest gross returns and benefit - cost ratio. Greengram cultivar CO 8 (V3) grown under minimum tillage method followed by post emergence herbicide spray of imazethapyr + imazamox @ 80 g ha-1 at 20 DAS (M3) can be recommended for summer rice fallows considering the yield and profitability.
