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.

    Vegetative propagation of promising jackfruit (Artocarpus heterophyllus Lam.) types
    (Department of Pomology and Floriculture, College of Agriculture,Padannakkad, 2018) Ashok Madala, KAU; Rajagopalan, A
    The investigation on ‘Vegetative propagation of promising jackfruit (Artocarpus heterophyllus Lam.) types’ was conducted at the College of Agriculture, Padannakkad, Kasaragod during the period 2017 - 18 to evaluate the success of epicotyl and softwood grafting in promising types of jackfruit and to examine the variation among jackfruit types with respect to grafting methods. The experiment comprised of five promising types of jackfruits viz., V1 - Varikka - early bearing (KJ 186), V2 - Gumless (KJ 397), V3 - Seedless (KJ 180), V4 - Cluster (KJ 182) and V5 - Muttam varikka (KJ 231) and two method of grafting i.e., M1 - epicotyl grafting and M2 - softwood grafting. The experiment was laid out in factorial CRD with three replications. The different jackfruit types showed significant influence for all the parameters studied except number of branches. Type V2 resulted in earliest sprouting (26.50 days) and maximum sprouting percentage of grafts (41.91 per cent) while type V3 recorded maximum survival percentage (66.94 per cent) and shoot length (8.13 cm). Maximum shoot girth (1.50 cm), number of nodes (7.50), number of leaves (7), length of leaf (12.34 cm) and breadth of leaf (5.64 cm) were observed in type V4. On the other hand, the maximum days to sprouting (30.33 days), minimum sprouting percentage (28.77 per cent), minimum shoot length (6.43 cm) and minimum number of leaves (5.17) were recorded in type V5 while type V1 showed minimum survival percentage (38.89 per cent), shoot girth (1.15 cm), leaf length (8.41 cm) and breadth of leaf (4.22 cm). Among the methods of grafting, the results on percentage of sprouting and survival as well as number of branches were not significant while all other parameters showed significant effects. Epicotyl grafts resulted in early sprouting of buds (26.00 days) and maximum shoot length (7.36 cm) whereas maximum shoot girth (1.36 cm), number of nodes (6.13), number of leaves (6.33), length of leaf (11.16 cm) and breadth of leaf (5.29 cm) were observed in softwood grafts. The interaction of varieties and methods of grafting were significant in most of the characters recorded. Interaction V2 x M1 was found better in early sprouting (24.33 days) and V2 x M2 resulted in maximum sprouting percentage (46.90 per cent) while V3 x M1 gave maximum survival of grafts (86.67 per cent). Hence, for the mass multiplication of Seedless type epicotyl grafting could be adopted and for other types like early bearing varikka, Gumless and cluster, softwood grafting could be practiced.

    Effect of heat stress on the expression patterns of different growth related genes in Malabari goats
    (Academy of Climate Change Education and Research, Vellanikkara, 2018) Angel Sunny, P; KAU; Bagath, M
    The impact of heat stress on growth performance of goats has been established fairly based on changes associated with phenotypic traits. However, not many reports are available on the genotypic traits which get altered on exposure to heat stress in livestock. Therefore, the study is an attempt to elucidate the molecular mechanisms governing growth performance during heat stress in goats. The primary objective of the study was to establish the influence of heat stress on the expression patterns of different growth related genes in Malabari goats. The study was conducted for a period of 45 days in twelve Malabari goats randomly allocated into two groups: MC (n=6; Malabari control) and MHS (n=6; Malabari Heat stress). Goats were stall-fed with a diet composed of 60% roughage and 40% concentrate. All animals had access to adlibitum feed and water and they were fed and watered individually. The MC goats were placed in the shaded pens while MHS goats were exposed to heat stress in outside environment between 10.00 h to 16.00 h. At the end of study period, all 12 animals were slaughtered and their liver tissues were collected for gene expression and histopathological studies. The temperature-humidity-index (THI) inside the shed (74.9) proved that the animals were not stressed while in the outside environment (86.5) the animals were extremely distressed. The hepatic growth hormone (GH), growth hormone receptor (GHR), insulin-like growth factor-1 (IGF-1), leptin (LEP) and leptin receptor (LEPR) gene expression patterns were significantly (P<0.05) lower in heat stress group as compared to the control group animals. In addition, negative correlation (P<0.05) was also established between THI and all the growth related gene expression in the study. The hepatic histopathological section showed more fatty and degenerative changes (P<0.05) in hepatocytes in MHS group as compared to MC group. The study offers the first thorough insight into the expression patterns of different growth related genes during heat stress exposure in goats. Further, the study established GH, GHR, IGF-1, LEP, LEPR genes to be the ideal markers to reflect growth potential in Malabari goats. The findings from this study provide some crucial initial information on how different growth relatedgenes are expressed when Malabari goats are subjected to heat stress. This information might be of high value in assessing the growth performance of goats and may provide useful information pertaining to nutrient supplementation to the heat stressed goats.

    Development and quality evaluation of granular fruit bars
    (Department of Community Science, College of Agriculture,Vellayani, 2017) Meghna, K; KAU; Nirmala, C
    A study entitled “Development and quality evaluation of granular fruit bars” was conducted at the College of Agriculture, Vellayani during the period 2015-17, with the objective to develop granular fruit bars using fruit pulp, grains, nuts and pulses and to ascertain sensorial quality, chemical and nutritional composition, shelf life and consumer acceptability. Papaya, pineapple and other ingredients such as puffed rice, oats, bengal gram dal, ground nuts, dried fruits and Jaggery were purchased from the market. Outer coat of granular fruit bars were developed using pineapple pulp (T1), papaya pulp (T2) and blended fruit pulp (T3). Food adjuncts such as sugar and pectin were added to obtain good texture. Fruit bars were dried in tray drier at 55-60°C. After the development of three fruit bars, TSS was recorded. Drying characteristics like moisture loss, drying time and yield ratio was ascertained. Moisture loss was higher in T1 (Pineapple bar) and low in T2 (Papaya bar). Drying time of T1 (Pineapple bar) was on par with T2 (Papaya bar). Drying time required for T3 (blended bar) was 10.84 hours. High yield ratio (0.81) was observed for T2. The filling for granular fruit bars were standardised using energy sources such as puffed rice, flaked rice and oats. Puffed bengal gram dhal and roasted groundnuts were serve as protein sources. Jaggery was used as the sweetening agent for the product. To standardise granular bar, different combinations of different ingredients were formulated. Sensory quality, nutritive value, chemical score and NDP Cal% of each proportion was computed to identify the best combination. Six treatments were formulated with varying amounts of ingredients ( Rice flakes, puffed rice, oats, Bengal gram dhal, ground nuts, jaggery and osmotically dehydrated jackfruits). Three treatments with appreciable nutrient content, chemical score and NDP Cal% were selected for further study. T1 obtained the highest chemical score of 109.97 followed by T3 (98.65) and T2 (93.72). T1 was observed to have the highest value of NDP Cal% (12.38%) and T2 had the lowest NDP Cal% (9.96%). Based on above parameters T1, T2 and T3 selected for further study. T1 was identified as best formulation with the highest score of 35.30 in sensory evaluation using hedonic rating scale. The formulated outer fruit bar coat was cut into pieces and filled with T1 (30:25:10:5:5:20:5) and pressed into bars and designated as A1 (pineapple coated granular fruit bar) A2 (papaya coated granular fruit bar) and A3 (blended bar coated granular fruit bar.), thus the final products were A1, A2 and A3 GFB (granular fruit bars). The products (A1, A2 and A3) were packed in laminated pouches and stored at ambient condition. Quality parameters such as sensory acceptability, chemical and shelf life of final products were ascertained initially and monthly intervals. Sensory evaluation of final products revealed highest mean rank score for A2. Polyphenol (4.21mg) was higher in A2 and all the other chemical components were higher in A1. TSS recorded for A1 was 78.2°B, reducing sugar (43.02%) and acidity (1.32%). A1 has highest fibre content of 0.46g per 100g. The other nutrients, moisture, protein, carbohydrate, energy and fat content were higher in A3 and was 20.02%, 40.16 g, 115.06 g, 461.0 KCal and 7.71g respectively. A3 had high total minerals (4.5 g) calcium, iron, sodium and potassium and the values were 2.36 mg, 2.52 mg, 635.52 mg and 45.03 mg respectively. High vitamin C content was observed for A 3 (23.38 mg) and high β carotene content was noted for A2 (269.798 μg). Changes in moisture, acidity, sensory appeal and microbial growth if any was recorded monthly. It was observed that there was a gradual increase in moisture and acidity in stored granular fruit bars. A3 showed highest moisture content and A1 showed highest per cent of acidity throughout the storage period. Stored GFB showed gradual decrease in all sensory parameters. Microbial evaluation of GFB, revealed that, no bacterial colonies were seen in (cfu 1×10-7) in dilution initially. Few colonies of bacteria and fungus were seen in first month and number of colonies exceeded the safe limit in second month. Consumer acceptance and preference study among 50 adolescents was rated high for A2. The product cost was computed and it was found to be Rs. 36.63/- for A1, Rs. 18.75/- for A2 and Rs. 31.53/- for A3. GFB were nutrient dense, ready to eat product with fruits, grains and pulses with shelf life of one month.

    Impact of projected climate change on cropping pattern of different agro ecological units of southern Kerala
    (Acadamy of Climate Change Education and Research Vellanikkara, 2017) Sukanya, K S; KAU; Sunil, K M
    Climate change poses an emerging threat to sustainability of social and economic development, livelihoods, and environmental management across the globe. Characterization of the ecosystems using the AEZ concept is a good decision making approach for variety of farming activities performed by the farmers and is a useful tool for the studying the impact of climate change. The objectives of this study are (1) to study rainfall variability and to determine water availability periods of Agro ecological units of southern Kerala under different climate change scenarios. (2) To study the impact of projected climate change on cropping pattern, crop calendar and the possible changes in the water requirements of major cropping systems prevailed in the various Agro ecological Units of southern Kerala. Daily rainfall data for the period 1991-2014 were collected from the India Meteorological Department, Thiruvananthapurm. Weather cock v.1.5 was used for converting the daily weather data into standard week, month and seasonal formats. It is also used to compute PET and Thornthwaite water balances. CROPWAT model was used for the calculations of crop evapotranspiration, crop water requirements and irrigation requirements for the development of irrigation schedules under various management conditions and scheme water supply. The annual rainfall availability in most of the AEUs of Thiruvananthapuram, Kollam and Pathanamthitta districts show a decreasing trend in the projected climate and an increasing trend in Idukki, Kottayam and Alappuzha. The number of annual rainy days generally shows a decreasing trend. The seasonal rainfall of southwest and summer monsoon will show an increase from the current situation where as northeast monsoon and winter will have a decreasing trend. In projected climate of both RCP 4.5 and 8.5 there will be high probability of having reduction in the number of months having the surplus and an increase in the number of deficit. The crop evapotranspiration values of rice based cropping system will show a tendency to increase. In perennial cropping systems of coconut based and rubber the projected crop evapotranspiration will have a reduction from the present situation whereas in coffee based cropping system the ETc will have an increasing trend. The irrigation requirement of all the major cropping systems will increase from the present situation except in the case of rice-fallow-fallow. The length of growing period of the cropping season in the major rice growing areas of different AEUs are getting shorter with slight differences among various agro-ecological units, implying a higher risk of operating under projected climate as per RCP 4.5. The sowing date will be delayed up to three to five weeks. It can be also observed that the crops will have to suffer water stress during the grain filling stage and will be under heavy rains at time of harvest in almost all the considered cases.
