It helps to enhance production without adding much to the extent of land under cultivation. Area under rice in Kerala fell from 2.34 Lakh hectares in 2009-10 to 1.99 lakh hectares in 2015-16, the production corresponding to the above period registered a reduction of only 0.49 Lakh tones. Availability and access to quality seeds is one of the important aspect in maintaining at least the current level of production of rice in the state. Hence the present study was carried out to document the major rice seed supply chains in Kerala and to assess their economic performance, to elucidate the demand - supply gap in rice seed production and to conduct a SWOC analysis of the rice seed market in the state. The study was conducted in three major rice growing districts in Kerala viz., Palakkad, Alappuzha and Thrissur. From each district one block having maximum area under rice cultivation was selected and from each block two panchayaths were randomly selected. Primary data collection was done from 60 rice farmers and 60 rice seed growers in the selected panchayaths. Relevant data were also collected from Kerala State Seed Development Authority (KSSDA), Kerala Agricultural University (KAU) research stations and National Seeds Corporation (NSC). Rice seed supply chains in Kerala could be broadly classified into formal and informal system. The informal system constitutes farm saved seed and seed exchange among farmers, friends and relatives. The formal rice seed supply system constitutes institutionalized rice seed supply mechanisms. Major formal rice seed supply chains identified were KSSDA rice seed supply chain, KAU rice seed supply chain and NSC rice seed supply chain. Economic performance of rice seed production under the identified supply chains was analyzed using Commission on Agricultural Costs and Prices (CACP) cost concepts and Benefit Cost Ratio (BCR). BCR of rice seed production in KAU research farm was 0.76 followed by 0.89 for KSSDA and 1.04 for participatory rice seed production in KAU. Seed production systems in KAU research farms and KSSDA was found to be economically inefficient as indicated by the BCR values. Demand- supply gap in rice seed production was worked out as the difference between the quantity of high yielding variety seed required for the area reported and the quantity of seeds distributed through the formal supply chains. The demand supply gap over the years (2012 to 2016) ranged from 30 per cent to 50 per cent of the total demand indicating that 50-70 per cent of total rice seed demand was met through formal rice seed supply system. KSSDA was found to be the major source of rice seed supply (88.97 per cent) followed by NSC ( 8.57per cent) and KAU (2.46 per cent). Constraints faced by rice farmers in access to quality rice seed was analyzed using Garrett ranking technique. Timely availability of rice seed was the major constraint followed by poor rice seed quality. Analysis of constraints faced by seed growers have shown that lack of timely procurement and payment was the major constraint. Strengthening of seed production system with establishment of separate seed certification agency and sufficient seed storage and processing facilities at seed growers’ level was suggested.ennullThesis
