Farmers involved in testing improved varieties can be quick to see and take up possibilities. Hill farmers in India and Nepal given improved maize quickly chose those that fitted into empty niches in their traditional farming systems. In western India they chose maize suited for intercropping with horsegram. And in Nepal, subsistence farmers took the new varieties and intercropped them with finger millet in terraced agroforestry systems. Previously, farmers could do little with obsolete varieties - between 11 and 27 years old - that gave poor yields and didn't fit their farming systems. Now, nearly all farmers who have access to seed of improved maize choose to use them to boost production of food and fodder in various ways. The seed is also spreading through self-help groups and from farmer to farmer. Project Ref: PSP09:

Maize varieties identified through participatory varietal selection (PVS) for western India and mid-hills of Nepal. These are JVM 421 varietyfor western India and Manakamana 3 forthe mid-hills of Nepal (Table 1). Both of these open-pollinated varieties were introductions from the International Maize and Wheat Improvement Centre (CIMMYT). Variety JVM 421 is a derivative of ZM 421 from CIMMYT Zimbabwe and Manakamana 3 is from Population 22 of CIMMYT, Mexico. These varieties were given to farmers for testing because they had traits that farmers had specified as desirable. Table 1. Description of maize varieties identified by PVS in India and Nepal
Maize is the most important crop of the hill districts of western Indian Gujarat, Rajasthan and Banswara. Surveys conducted by GVT showed that the adoption of improved cultivars of the major crops including maize was extremely low (Joshi and Witcombe, 1995; Witcombe et al., 2003). Similarly, maize is by far the most important cereal in the subsistence agriculture of the middle hills of Nepal (Tiwari, 2001). Both in India and Nepal, farmers largely grew old and obsolete varieties that gave low yields. In India, Witcombe et al. (1998) found that the average age of maize varieties was 27 years in MP, 20 years in Gujarat and 11 years in Rajasthan. In Nepal, Population 22 was tested in formal coordinated trials from 1995 to 1999 but was not released because of its late maturity. When tested in PVS trials it was found to be the most preferred by farmers of the mid-hills who intercropped maize/finger millet in terraces that had trees on the margins (Tiwari, 2001). This demonstrated the value of involving farmers by using PVS.
The main commodity is the maize grown in the semi-arid tropics in India and semi-arid rainfed mid-hill farming systems of Nepal. The maize variety in India is better for intercropping with legumes such as horsegram(PSP08 on intercropping of maize with improved horsegram; and PSP14 on improved horsegram better adapted to intercropping). The maize variety in Nepal is better for cropping where there are multipurpose trees on the terrace bunds that shade the crop. The process of participatory varietal selection can be applied to all major crops.
The introduction of new varieties of maize in the rainfed conditions can be linked with the rainfed rabi fallow projects (PSP01 and PSP35) where the maize varieties can be followed by the cultivation of pulses. It can combine with the seed priming (PSP28 and PSP30). The maize variety in India is more suitable for intercropping with horsegram(PSP08 and PSP14). The maize variety in Nepal can be combined with Agroforestry systems where multipurpose trees are grown on terrace bunds and with improved finger millet. Since farmers evaluate varieties for all traits including fodder quantity and quality then clustering with improved livestock nutrition would be synergistic. In PVS, the new intervention is a crop variety which can combined with the testing of other interventions that are synergistic with new crop varieties, i.e., crop protection and improved crop agronomy interventions. Clustering can be done with the following RNRRS outputs:
How the outputs were validated: In PVS, validation is always by the first of the end users of a new variety – farmers - in on-farm participatory trials with participatory evaluation using a mother and baby trial design (Witcombe 2002). With Nepal as an example, the mother trials involved matrix ranking for many traits by farmers in focus group discussions (FGDs) at about 80 days after sowing, approaching harvest, and 3-4 months post-harvest. Focus groups of 5-8 farmers (male and female) ranked the varieties for each trait separately and overall. In post-harvest FGDs, farmers evaluated characteristics such as shelling percent, grit to flour ratio, taste, susceptibility to stored grain pests and market value. The trials were replicated to provide tests of statistical significance. The on-farm trials and on-station trials were done by many organisations (Table 2 and see "Who are the Users"). Additional on-farm validation involved informal research and development (IRD) where many farmers were given a small quantity of seed for growing alongside their local control without collection of formal data. The new varieties yielded much more grain than the local varieties (up to 52%) in both research station and on-farm trials (Tables 3 and 4) and they also excelled for other traits (Table 5). Table 2. How the varieties were tested from 1995 to 2005

Who are the Users? In both India and Nepal farmers do not have to change how they grow these maize varieties as they do not require any special cultivation practices. The users are male and female farmers who are from all social groups representing resource-rich, resource-medium and poor farmers. In western India, farmers use JVM 421 as one component of the maize farming system. It is of longer duration than other varieties such as GM-6 so it is preferentially grown on the better soils in the lower lands. Consequently it does not occupy a very large proportion of any individual farmer’s land but will make a disproportionately large contribution to total maize production. It is grown for grain, for home consumption and for sales, and for its high quality stover. Some of the grain will be kept for resowing. In Nepal, farmers of these complex hillside farming systems needed more varieties to fit all of the niches and to satisfy their multiple needs for grain and fodder. Manakamana-3 was tested in the formal trials system of Nepal from 1995 to 1999 but was not identified for release because of its late maturity. However, evaluation by farmers in PVS trials from 1999 to 2001 revealed that farmers did not perceive late maturity to be a problem as there is no possibility of a following crop in the same year. They traded off any possible disadvantages of the late maturity of Manakamana-3 against its higher grain yield, shade tolerance and other useful traits. Where the outputs have been used: The outputs are being used in the rainfed semi-arid agricultural system in India and Nepal. The outputs are being used in India in the three western states of MP, Rajasthan and Gujarat in the better lands of the hilly districts of Jhabua and Ratlam (MP), Panchmahals (Guj) and Banswara (Rajasthan). It is certain that JVM 421 is adapted to maize growing areas outside of these districts and likely that seed has been distributed there but no assessments have been made. In Nepal Manakamana 1, is released for the mid-hills of the eastern, central and western regions at 1000 to 1700 m altitude. Following dissemination programmes, is now being used by hill farmers in more than 20 districts of Nepal. Scale of Current Use: The scale of the current use can be extrapolated from the scale of promotion activities. Participatory assessments show that both JVM 421 and Manakamana-3 are adopted by most (90% or more) of the farmers that have access to seed. The amount of seed that has been distributed is large and it has been to many farmers. Given that farmers also distribute seed of these varieties once they have sufficient for resowing for themselves the spread is larger than the seed supply. The complicating factor in describing the usage is that as an open-pollinated variety is grown from year to year it is progressively less pure because of cross-pollination to other varieties. The scale of the promotion (as an indicator of usage) is described here for JVM-2 and for Manakamana-1 under Promotion of Outputs. India Seed production was undertaken by JNKVV and GVT from 2002 to 2006. JNKVV produced seed on the research farm and GVT the self-help groups of farmers (Table 6). By 2006, the total coverage by JVM 421 from seed distributed by GVT and JNKVV was sufficient for about 400 ha. Over 100 farmers had received seed directly from the two institutions in Gujarat, Rajasthan and MP but many more farmers would have received seed in the farmer-to-farmer distribution. Further seed production is being undertaken in the rainy season of 2006 sufficient for sowing a further 200 ha. Table 6. Quantity of seed of new variety JVM 421 by GVT west to GOs, NGOs and farmers
Policy and Institutional Structures, and Key Components for Success: Western India: The promotion of varieties in these poor parts of western India has been inefficient as the areas are remote, the purchasing capacity of the farmers is low, and the demand for seed unpredictable because it varies with the rains. Farmers also have limited access to the government extension services. They should visit the local farm science centre (KVK) but few farmers have the resources to do so. Front line demonstrations by Departments of Agriculture are few and conducted in more favourable agricultural environments. Hence, the main activities for dissemination of seed have been through projects such as the western India rainfed farming (WIRFP) which has now completed. Ongoing projects include the Madhya Pradesh Rural Livelihoods Project (MPRLP) and Poverty Initiative Programmes (DPIP), National Watershed Programme, Community Resource Centres under District Rural Development Agency. Also some NGOs such Action for Social Advancement (ASA), PRYAS, SAMARTHAN. They have collaborated with GVT in supplying seed of maize varieties. Nepal. The dissemination of Manakamana 3 has been done through the Nepal Agricultural Research Council (NARC) Agricultural Research Stations such as Pakhribas, Kabre, Dailekh and Lumle; through the National Maize Research Programme, Rampur; the Hill Maize Research Programme (HMRP), CIMMYT, Kathmandu; the District Agriculture and Development Offices (DADOs); and partner NGOs such as TUKI Association, Sindhupalchwok, LI-BIRD, FORWARD, CEPRED, TTRI, ABTRACO, CAERD, DOS-Gorkha. Of these the HMRP is perhaps the most important and has provided a platform to spread the variety to more than 20 districts in the mid-hills and have an influence in promoting community-based seed production (CBSP). Policy: In India, the seed production of maize varieties takes place on the basis of assured, written orders (indents). Unless there is an indent for seed GOs will not produce it. This applies rigorously for breeder seed and to a lesser extent for certified or truthful seed. Seed production of JVM 421 has been limited because indents have not been received from the department of agriculture in the state who, in turn, are not fully aware of the variety. Thus there is an inadequate linkage. Although the situation is similar in Nepal there is a closer linkage between the District Agricultural Development Officers with farmers and then with NARC that provides a better assessment of demand. How well the demand is translated into demand will vary. Capacity strengthening: To promote adoption of new varieties to any significant level improved capacity in the following areas are required:

Potential Barriers Preventing Adoption of Outputs: A barrier is a lack of a sustainable seed supply system for open-pollinated varieties of maize in India and Nepal. In Nepal such a system faces even greater challenges because the mid-hill regions are remote and the terrain does not allow large weight and volume of seed to be economically transported over even relatively short distance. The public sector, particularly in India, has suffered from the vicious circle of a lack of demand resulting in lack of seed production resulting in lack of demand because demand can only come if farmers have seen the variety. The process has to start with extension by the departments of Agriculture who demand seed for this process. However, there is a disconnect between extension and research. One possibility is an increased role for the private sector. However, for the formal private sector there is the problem that investment in more favourable agricultural areas (irrigated areas in India and the terai in Nepal) and hybrid seeds. The other private sector is the farmers themselves. In India, working in a poverty-focused approach by establishing groups within villages has been fraught with problems caused mainly by the low and erratic productivity that varies with the rains along with poor access to markets. In India, there is a need to establishing groups in more favourable areas that are not too remote from the target areas and where emphasis is placed on training in commercial matters relating to the seed business. In Nepal, erratic production (and erratic demand) is less of a problem as the rainfall is higher but the need for decentralisation is far greater because of difficulties of transportation. However, the motivation to produce quality seed of the staple crop maize is probably higher and mountain communities in Nepal are used to cooperative efforts in, for example, the management of community forests. How to Overcome Barriers to Adoption of Outputs: The most important changes vary with the situation. In India awareness raising to create demand is the most important, while in Nepal it is approaches to community –based seed production. In India, awareness needs to be raised at all levels (State Agricultural Universities, NGOs, Departments of Agriculture and the private sector) about the JVM 2 (and other new maize varieties such as GM-6). Generally the awareness of new varieties takes a long time to reach the stakeholders. In both India and Nepal steps have been taken to try and produce seed on the scale that is demanded. Lessons need to be learnt from these experiences (such as, in India, not attempting to have a poverty-focused approach to seed production in poor villages where seed cannot reliably be produced in drought years). Such lessons have to be applied but also modifications need to be tested to add to these lessons (see PSP36). Suitable modifications, when soundly based on lessons from current initiatives, could add great value. All this requires a fundamental change in seed-production based development by placing as much emphasis on monitoring and evaluation for lesson learning as for the seed production itself. This has proved to be difficult as development-oriented NGOs are more concerned with the results than the process. Lessons Learned: Using Rogers (2003) diffusion of information as a framework for the lessons learnt:
Hence, the provision of a sustainable seed supply and the changing of mindsets of researchers and extensionists are the most important factors in getting this research into use. Poverty Impact Studies: Very little impact assessment has been done, so far, on these varieties. There is some information on the impact of ZM 421 (JVM 421) in the publication below. Yadavendra, J.P. and Witcombe, J.R. 2006. The impact of new maize and rice varieties on the livelihoods of poor farmers in marginal agricultural areas of western India. Paper presented in International Symposium on Participatory Plant Breeding, 17-19 June 2006 at M.S. Swaminathan Research Foundation (MSSRF), Chennai. How the Poor have Benefited (including gender and other poverty groups): The target farmers were the indigenous, resource-poor farmers who benefited the most from the adoption of these PVS varieties. Farmers’ perceptions for JVM 421 in India showed that significantly more farmers preferred it for higher grain yield, higher fodder yield and good eating quality (Fig. 1) over the local variety. The farmers’ local check varied from place to place and more farmers perceived JVM 421 to be later maturing. The 20% who felt it to be earlier maturing were probably comparing it to a very late maturing local variety.
Fig. 1. Farmers’ perceptions for JVM 421 relative to the local checks in Western India - MP, Raj and Guj (left). It can be compared to GM-6 (right). ZM-421 can be seen to have a higher grain and fodder yield than GM-6 and to be a later-maturing option that is more adapted to better fields.
Fig. 2. Farmers' perceptions of Manakamana 3 compared with Manakamana at the post-harvest stage (mean over 1999 and 2000) traits. Farmers' perceptions as to whether the test varieties were better or worse than the local variety are indicated by lines in percent. The shorter the line, the more similar the variety is to the local variety. In focus group discussions male and female farmers were in a good agreement to rank Manakamana-3 as first over years and locations in Nepal. At the pre-harvest stage farmers liked Manakamana-3 for its shade-tolerance, longer ears, taller plants, lodging resistance, stay-green characteristic and better fodder quality, and resistance to foliar diseases particularly turcicum blight. At the post-harvest stage Manakamana-3 was rated better for shelling per cent, cob size, grain size and quality, cooking quality and lower susceptibility to stored grain pests (Fig. 2). The impact of Manakamana 3 on the livelihoods of farmers is yet to be documented. However, farmers report that the yield benefit from Manakamana 3 is between 20-50% over the local variety depending on location. Farmers perceived that food availability had increased from 3 months to 4-5 months with the adoption of Manakamana-3. The yield gains from the new varieties showed that the participating farmers benefited from the new varieties given in PVS. The most important aspect is the better performance of new varieties in rainfed conditions of farmer fields where these varieties were more drought tolerant. Substantial increase in yield and fodder for the rainfed and small holders has great implications on the livelihoods of poor people. The increased yields reduced poverty and increased food security and purchasing power of the participating farmers who had improved their living standards by using additional incomes from increased yields.
