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.

    Evaluation of bush dolichos bean [Lablab purpureus (L.) sweet] for yield and quality
    (Department of Vegetable Science, College of Agriculture, Vellayani, 2021) Maneesha, P K; KAU; Sarada, S
    The present investigation entitled “Evaluation of bush dolichos bean [Lablab purpureus (L.) Sweet] for yield and quality” was conducted at the Department of Vegetable Science, College of Agriculture, Vellayani, from June 2019- December 2020 to evaluate the adaptability of bush dolichos bean in Kerala based on growth, yield and quality. The experimental material consisted of 25 bush dolichos bean genotypes. The experiment was laid out in RBD with two replications. Analysis of variance revealed significant differences among the twenty five genotypes for all the characters studied. Among the genotypes, HA- 4 recorded the highest plant height of 65.75 cm. The variety HA-3 recorded the highest plant spread of 48.95 cm. The highest number of primary branches plant-1 was recorded by HA-4 (5.70), Arka Jay (5.65) and HA-3 (5.55) were on par with it. HA-4 recorded the highest leaf area of 13.35 cm2. Earliest flowering was observed in the genotype VRBSEM- 15 (22.95 days), while first flower appearance was late in HA- 4 (67.00 days). Fifty percent flowering was earliest in VRBSEM- 15 (25.95 days). The highest number of racemes plant-1 was recorded in HA-4 (6.46) and the longest raceme in the variety Arka Jay (34.35 cm). Arka Sambram was the earliest to harvest (61.30 days) followed by Arka Soumya (61.80 days), which were on par. The highest per centage of pod setting was recorded in HA-4 (14.85) followed by HA-3(14.50), which were on par. Co (Gb) 14 recorded the highest pod length (10.63 cm), pod girth (2.60 cm) and pod weight (6.75 g). Among the twenty five genotypes, nineteen genotypes exhibited light green pod colour, five dark green pod colour and one reddish green pod colour. The highest number of pods plant-1 was found in HA-4 (47.75). The seed colour of eleven genotypes was red, eight pale white, three white, two black and one light brown. The highest number of seeds pod-1 was in Co (Gb) 14 (4.35), which was on par with Arka Jay (4.25) and VRBSEM- 8 (4.25). Co (Gb) 14 recorded the highest weight of 100 seeds (35.45 g). The highest yield of 152.87 was recorded by Co (Gb) 14 which was on par with Arka Jay (148.82g) and HA-4 (148.52g). The highest yield plot-1 of 3.057 kg was recorded by Co (Gb) 14. Two genotypes, viz., Arka Jay (2.976 kg) and HA-4 (2.970 kg) were on par with it. Co (Gb) 14 recorded the highest crude protein and fibre content of 21.40 and 2.050 per cent respectively. The cooking quality of all the twenty five genotypes were found to be good. Incidence of leaf webber and anthracnose disease was noticed. High phenotypic and genotypic coefficients of variation (PCV and GCV) were observed for the characters like days to first flowering, pod setting, pod length, pods plant-1, yield plant-1, yield plot-1 and fibre content. High estimates of heritability coupled with high genetic advance as per cent of mean were recorded for the yield components. Yield plant-1 had a significant positive correlation at genotypic and phenotypic level with raceme length, plant height, pod length, primary branches plant-1, number of racemes plant-1, plant spread, days to first flowering, pod girth and pod weight. Path coefficient analysis revealed that raceme length (0.9760) exerted the highest positive direct effect on yield plant-1 followed by number of racemes plant-1, primary branches plant-1, plant height, pod girth and pod weight. The genotypes were ranked based on selection index score considering the characters viz., plant height, primary branches plant-1, number of racemes plant-1, raceme length, pod girth and pod weight. HA-4 recorded the highest selection index score of 136.72. Based on the mean performance of the genotypes for various characters and selection index score, the top ranking genotypes HA-4, Co (Gb) 14 and HA-3 were found suitable for growing under Kerala conditions.
