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.

    Groundwater irrigation: management, adaptation and economic costs under declining resource conditions
    (Department of Agricultural Economics, College of Horticulture, Vellanikkara, 2017) Seenath Peedikakandi; KAU; Indira Devi, P
    Groundwater is the major source of domestic use and irrigation in Kerala, accounting for 39 per cent of net irrigated area. Irrigated agriculture in the state shows continuous increase over years. At the same time Kerala is reported as third among the states with highest depletion of groundwater. This situation poses challenges in agricultural production. The study ‘Groundwater irrigation: Management, adaptation and economic costs under declining resource conditions’ was undertaken, in this background. The objectives of the study were to analyse the extent of decline in groundwater resources and farmers’ understanding of the same, to analyse the extraction practices, management and economic efficiency of groundwater irrigation and coping (short term) and adaptation (long term) strategies towards management of groundwater decline and the economic cost of adaptation strategies. The study was conducted in Palakkad district of Kerala. Based on the stage of ground water development, three Block Panchayats viz., Chittur (over exploited), Malampuzha (critical) and Pattambi (semi-critical) were selected for the study. 50 Open Well (OW) irrigated and 50 Bore Well (BW) irrigated farms from each BP were randomly selected from the Grama Panchayats (GPs) where observational wells of the GWD (Ground Water Department- Kerala) are situated. Primary data was collected from the sample farms through field visits using pre-tested structured interview schedule and through direct observation. PRA (Participatory Rural Appraisal) was also conducted in each BP to draw the time line of changes in ground water status and social perceptions. Secondary data on monthly water levels of Groundwater Monitoring Wells (GMWs) maintained by GWD (Palakkad),rainfall data and published reports were used for the study. Statistical tools like descriptive analysis, regression and Stochastic Frontier Function were employed for analysis of the data. In most of the GMWs in the study area, the Water Level from Ground (WLG) has been declining over the years. The trend was more predominant during early summer (Dec.–Jan.) in Chittur and Malampuzha and in late summer in Pattambi BP. Regression analysis showed that WLG was significantly influenced by one year lagged rainfall in Chittur and current year rainfall in Malampuzha and Pattambi. The average well density was 205/km2 with highest in Pattambi. Density of defunct wells was highest (45/km2) and the average functional age of bore wells was lowest (7 years) in Chittur. The depth of well was highest in Chittur where bore well depth (136 mbgl- meters below ground level) was double than that of Pattambi. Coconut based cropping system was prevalent in most of the farms except in Malampuzha where paddy was the major crop. Flood, basin and sprinkler irrigations were found to be more common in Malampuzha and Pattambi BPs, while drip irrigation was prevalent in Chittur. Cost of irrigation in Chittur was about Rs. 29,000/ha/year which accounted for 37 per cent of cost of cultivation. Annual net return per ha. of farm was lowest (Rs. 17,640/-) in Chittur due to low cropping intensity. Stochastic Frontier Analysis indicated that mean economic efficiency was high (99.9%) in Chittur as most of the farms were functioning along the cost frontier. The variability among the farms in Chittur was low. Respondents opined that groundwater is declining over the years irrespective of the region. It has been so, for more than a decade in Chittur affecting socio-economic well-being of farmers. They attributed intensive extraction through bore wells and low rainfall as the major reasons for the decline. Farm level adaptations to water scarcity are classified under ‘supply management’ (methods that facilitated increase in quantity of water available for irrigation) and ‘demand management’ (methods that tried to use the water effectively through minimizing the use) strategies. The supply management strategies were mainly exploitative in nature which included digging new bore well (52-58%), improved draft technology with compressor pumps (58%), taking pits for water conservation (7%), coconut husk burial (12%), coconut leaf mulching (18%) and dependence on water markets (8%). Digging new bore well was the most common supply management strategy in Chittur which is highly capital intensive. The average cost amounted to Rs. 8,520/ha/year. Intensive extraction was done by excessive use of subsidized electricity. Adoption of drip irrigation (60%) was the most widely practiced demand management strategy which cost about Rs. 22,000/ha/year. Cropping pattern change from paddy and sugarcane to coconut was also observed. About 18 per cent of the land area in Chittur was kept fallow due to water scarcity. The study brings out results that suggest policy interventions in regulating bore well digging and revisiting the power subsidy system. In Chittur area, where the rainfall is scanty, extension of the Right Bank Canal of the Chittur River irrigation project is the most feasible solution. Taking up on-farm research trials in the area to suggest efficient farming systems and practices may also be done. Simultaneously water resource conservation strategies are to be popularized through awareness creation, capacity building programmes and subsidy support.

    Supply chain analysis of marine fish marketing system in Kerala
    (Department of Agricultural Economics, College of Horticulture, Vellanikkara, 2017) Jeyanthi, P; KAU; Jesy Thomas, K
    Fisheries is a major allied sector of agriculture contributing about 0.8 per cent to the Gross Domestic Product (GDP) and 5.15 per cent to agricultural GDP in India. Marine fisheries supports around 10 million people providing livelihood and employment directly or indirectly. Fish also provides more than one billion people living below the poverty line with most of their daily animal protein requirement globally. Kerala is a state known for its fish consumption which is more than four times the national average. However, the marine domestic fish marketing system faces several challenges in the process of distributing fish from the producer to the consumer. The study was conducted in Kerala state, which is the fourth largest fish producer in the country, and covered coastal and land locked (non-coastal) regions. The objectives of the study were to identify the supply chain of selected fish species, to assess the structure and performance of domestic fish markets, to examine the market integration and price transmission among the markets and to assess the consumer perception and suggest policy guidelines for improved fish marketing in Kerala. Two coastal districts viz., Ernakulam (E) and Kollam (K) and two land locked districts, Idukki (I) and Pathanamthitta (P) were selected and data was collected using simple random sampling from various marketing functionaries (producers, wholesalers, retailers and consumers). Since the species composition of marine fish landings is varied, the study focused on four high value (seer fish, shrimp, pomfret and tuna) and four low value but commonly consumed fish species (sardine, mackerel, anchovies, threadfin bream). Supply chain of the selected fish species was identified using the framework of Feller et al, 2006. Market performance of producers, wholesalers and retailers were assessed using Data Envelopment Analysis. The co-integration test was used to analyses the market integration of selected market pairs. Conjoint analysis was used to determine the attributes responsible for their fish purchasing behaviour. The constraints faced by the market functionaries were ranked using Rank Based Quotient. The generic supply chain of fish identified involved the auctioneer, wholesaler, retailers, secondary retailers, between the producer and the consumer. This is almost similar to the supply chain of other perishable like fruits, vegetables and flowers. The supply chain for sardine, tuna and thread fin bream also involved extra nodes in their supply chain due to industry specific demands like feed and other specialized products. The market structure of domestic fish markets was not efficient. The main reason being lack of infrastructure such as cold storage, well planned display and assemblage platforms, potable water and weighing balance. Market performance of producers was measured at the five landing centres in Ernakulam and Kollam and it was observed that only one market was efficient in each of the districts. It was revealed that the nature of inefficiency was due to scale rather than technology. In both Ernakulam and Kollam, only one wholesale market each was efficient and all other markets showed high technical efficiency i.e., above 0.80. In both wholesale and retail markets, the technical efficiency was relatively low in Idukki and Pathanamthitta with it being least in Idukki. It was revealed that the markets in the coastal regions showed relatively high technical efficiency than the land locked regions because of the higher volumes handled in the markets due to proximity with the landing centres, viz, the primary production centres, which is not so easily accessible to the land locked districts. Among wholesale markets, one market pair in Ernakulam, one in Idukki and one in Pathanamthitta showed co-integration and among retail one each in Ernkulam and Pathanamthitta showed co-integration. This indicates that in these markets there is a possibility of long run equilibrium in prices. The existence of low short run market integration (SRMI) at both wholesale as well as retail market levels was observed among the co-integrated market pairs. Consumer preference was for fresh fish in all the four districts studied in cleaned and cut form from retailers, wholesalers or wholesaler-cum-retailer. Sardine was the most preferred species in both coastal and landlocked regions of Kerala with more than 75 and 72 per cent of respondents, respectively, consuming it daily. The relative importance of attributes that consumer in Ernakulam and Kollam looked at while purchasing fish was fish species in fresh form and income. In Idukki and Pathanamthitta, availability and income were the relatively important attributes. Based on the pooled response of market functionaries in the selected districts the domination of middlemen was the major constraint for producers, wholesalers and retailers. Safety and quality of fish was the major constraint of consumers. The studies on efficiency of fish supply chain in line with the changing consumer preference are the future line of work towards sustainable fisheries development.
