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.

    Pesticide use pattern and monitoring of residues in cardamom in Idukki district
    (Department of Agricultural Entomology, College of Agriculture, Vellayani, 2013) Seena, S M; KAU; Naseema Beevi, S
    The field survey conducted among the farmers of Idukki district revealed that major pest infesting cardamom were shoot and capsule borer and cardamom thrips. For the timely management of these pests, farmers are following strict plant protection measures at an interval of 15 to 40 days with conventional insecticides. Farmers are widely applying heavy doses of chemicals especially the organophosphorus insecticides like phorate, chlorpyriphos, quinalphos, profenophos, methyl parathion and synthetic pyrethroids like cypermethrin and lambda cyhalothrin. Majority of the farmers resort to prophylactic spraying of plant protection chemicals rather than remedial measures. Adoption of IPM strategies are also negligible. Most of the farmers used their own spraying schedules for pest management. The pesticide use pattern in cardamom growing tracts of Idukki district shows that the farmers are applying plant protection chemicals aggressively and the liberal and continual use of pesticides has disturbing consequences on the ecosystem. In multiresidue mehod validation cardamom samples were spiked at five different levels viz. 0.01 µg g-1, 0.05 µg g-1 , 0.10 µg g-1 0.50 µg g-1 and 1 µg g-1 and extraction was carried out using various solvent/ solvent system and the modified QuEChERS method which gave 69.7–110% per cent recovery with RSD < 20 was selected and the same method was adopted for the estimation of pesticide residues from cardamom samples. In order to assess the residue level and to study the extend of contamination due to pesticides in cardamom, samples were collected from the cardamom growing plantations of Idukki district. Three major cardamom growing zones were selected namely Vandanmedu, Udumbanchola and Poopara in Idukki district and ten samples were collected from each location for a period of six months. Data on monitoring of pesticide residues in cardamom samples collected from the study regions for a period of six months revealed varying level of residues of several pesticides. Out of the total 180 samples analyzed, residues were detected in 173 samples and only seven samples were free of residues. Out of the 173 samples detected with pesticide residues, 160 contained multiple residues of pesticides whereas only 13 contained residues of single pesticide. Cardamom capsules contained residues of 16 different pesticide molecules belonging to organochlorines, organophosphates and synthetic pyrethroids. The most common contaminant was quinalphos which was detected in 121 out of 180 samples analysed. Other major contaminants include lambda cyhalothrin (104), cypermethrin (100), chlorpyriphos (87) and profenophos (64). Pesticides detected in cardamom which have no label claim in cardamom include Beta cyfluthrin (5), bifenthrin (3), fenpropathrin (4), fenvalerate (5), lambda cyhalothrin (104), methyl parathion (64) and triazophos (4) . A field experiment was carried out in order to study the curing process on removal of residues of quinalphos, chlorpyriphos, triazophos, cypermethrin, lambda cyhalothrin and imidacloprid. Curing process removed the residues of pesticides at varying levels. Processing factor was worked out for each chemical. Extent of removal of residues as a result of curing were: quinalphos (61.78-67.78%), chlorpyriphos (70.23-76.66%), triazophos (49.62-55.02%), cypermethrin (65.71-67.63%), lambda cyhalothrin (13.15-40.00%) and imidacloprid (75.56-77.32%).

    Standardisation of nutrient and weed management techniques for organic rice
    (Department of Agronomy, College of Agriculture, Vellayani, 2013) Murugesh, M S; KAU; Girija Devi, L
    The present investigation on “Standardisation of nutrient and weed management techniques for organic rice” was conducted at the Department of Agronomy, College of Agriculture, Vellayani, during 2012-2013. The objectives were to standardise the nutrient schedule, spacing and weed management techniques for organic rice and to assess the economic feasibility of the organic package. The experiment was laid out in the field in split plot design with combination of spacing, S (S1-20 cm x 15 cm and S2-15 cm x 15 cm) and weed management techniques, W (W1-stale seedbed and W2-hand weeding) as main plot treatments and nutrient schedule, N (N1-option-1 of the ad hoc recommendation of KAU: FYM 5 t + 800 kg oil cakes ha-1 (1/2 basal + 1/2 top dressing at active tillering stage), N2-option-2 of the ad hoc recommendation of KAU: FYM 1 t + green leaf manure 1t + dual culture of azolla + 2 kg Azospirillum + 2 kg P solubilizing bacteria + 1kg PGPR (mix 1) ha-1, N3-option-3 of the ad hoc recommendation of KAU: 1/3rd RDN as FYM, 1/3rd as vermicompost and 1/3rd as neem cake + 2 kg Azospirillum + 2 kg P solubilizing bacteria ha-1, N4-soil test based application–half as vermicompost and half as neem cake). The KAU Package of Practices Recommendation (FYM 5 t + 90:45:45 kg NPK ha -1) was taken as control. Closer spacing (S2-15cm x 15 cm), hand weeding (W2) and option-3 of the ad hoc recommendation of KAU (N3) significantly influenced plant height and DMP, while closer spacing (S2-15cm x 15 cm) and option-3 of the ad hoc recommendation of KAU (N3) only had significant influence on tiller production and LAI. Stale seedbed (W1) and closer spacing (S2-15 cm x 15 cm) had significant influence on most of the yield attributing characters, while, among nutrient schedule, N3 (option-3 of the ad hoc recommendation of KAU) attributed the maximum for yield contributing characters, but was on par with N4 (soil test based application) and also with N1 (option-1 of the ad hoc recommendation of KAU) for grain yield. The results on weed control revealed the superiority of closer spacing (S2-15 cm x 15 cm) and stale seedbed technique (W1) over others in controlling the weeds throughout the growth stages. However the weed control efficiency was the lowest in conventional (Control-KAU Package of Practices Recommendation) compared to the organic throughout the growth stages. The nutrient uptake was the highest in N3 (option-3 of the ad hoc recommendation of KAU) and the lowest in N2 (option-2 of the ad hoc recommendation of KAU). However, uptake study had also revealed the superiority of conventional (Control-KAU Package of Practices Recommendation) over organic in the uptake of nutrients. The net returns and B:C ratio were the highest in closely spaced plants (S2-15 cm x 15 cm) and in N3 (option-3 of the ad hoc recommendation of KAU). From the study it can be concluded that for realising higher grain yield in organic rice, a closer spacing of 15 cm x 15 cm (S2) is ideal. Any of the two weed management techniques, i.e., either stale seedbed (W1) or hand weeding (W2) can be practiced for controlling weeds. Option-3 of the ad hoc recommendation of KAU (N3-1/3rd RDN as FYM, 1/3rd as vermicompost and 1/3rd as neem cake + 2 kg Azospirillum + 2 kg P solubilizing bacteria ha-1) is the best nutrient schedule for realizing maximum yield from organic rice. The most economic package for organic rice production is the combination of closer spacing of 15 cm x 15 cm (S2), with stale seedbed technique (W1) of weed control and option-3 of the ad hoc recommendation of KAU (N3-1/3rd RDN as FYM, 1/3rd as vermicompost and1/3rd as neem cake + 2 Kg Azospirillum + 2 Kg P solubilizing bacteria ha-1) as nutrient schedule. The organic package was economically significantly superior to conventional package due to the premium price fetched by organic rice.

    Post harvest evaluation of bitter gourd as influenced by growing condition, harvest maturity, prepacking and storage
    (Department of Processing Technology, College of Agricutlure,Vellayani, 2013) Gajanan Baburao, Phuke; KAU; Geethalekshmi, P R
    The present investigation on “Postharvest evaluation of bitter gourd as influenced by growing condition, harvest maturity, prepackaging and storage” was carried out at the Department of Processing Technology, College of Agriculture, Vellayani during 2011-2013, with the objective to determine the stage of harvest maturity and its influence on postharvest life along with prepackaging and storage condition for organically and conventionally grown bitter gourd (var. Preethi) and to develop a postharvest package for extended shelf life with minimum nutritional loss. The experiment was conducted in three continuous phases such as determination of harvest maturity, precooling treatments, prepackaging and storage. Growth and development studies conducted for determining harvest maturity revealed that fruit length, width, weight and flesh thickness increased periodically till 15 days of flowering and percentage of increase was negligible 15 days after flower opening. But conventional fruits recorded higher values for all these physical characters at all the stages of maturity. Considering the development of both external and internal fruit characters, 14 and 15 days after flower opening were selected as optimum harvest maturity for further postharvest studies. Hydrocooling of harvested fruits with 150 ppm sodium hypochlorite was found as the best sanitizing treatment for maintaining the postharvest quality and increased shelf life for both harvest maturities (14 and 15 days) and growing conditions (organic and conventional). Prepackaging and storage trials revealed that prepackaging treatments, growing conditions and storage temperature had significant influence on shelf life and nutritional qualities of fruits. Fruits with 14 days maturity, grown organically, prepackaged in micro ventilated polyethylene and stored under refrigerated condition had resulted in lowest PLW. Nutritional parameters of fruits viz, protein, acidity, fibre, calcium, magnesium, iron and ascorbic acid were analysed before storage and at the end of shelf life. Before storage, none of the factors except growing conditions had significantly influenced the nutritional parameters. Fruits grown conventionally had higher protein and organic fruits exhibited high fibre, Ca, Mg, Fe and ascorbic acid content. Storage studies revealed that refrigerated storage after prepackaging in micro ventilated PE had lower nutritional and physiological changes during storage. From the study it can be concluded that bitter gourd (var. Preethi) fruits can be harvested at 14 days maturity for export and long distance market and 15 days for domestic market grown under both organic and conventional system in order to reduce the postharvest losses. Harvested fruits precooled with water containing 150 ppm sodium hypochlorite, prepackaged in micro ventilated polyethylene and stored under refrigerated condition was effective for extending the shelf life with minimum nutritional loss.
