This article identifies and analyses constraints in seed production in Indonesia and describes the major factors that account for the failure to produce quality seed potatoes. The study is based on interviews with staff from government and non-government agencies, farmer-seed producers, farmer cooperative members and end-user farmers. Facilities and techniques used in various stages of seed production and quality control were also evaluated. One of the major problems highlighted by the author is that seed growers claim to sell certified seeds, but they are not actually certified by the government. This has led to a lack of trust by farmers in seed growers and their reluctance to use seeds other than their own, which has in turn created a marketing problem for seed producers. Other constraints highlighted include lack of funding for institutions conducting research and development in potato seed production, limited cold storage facilities, re-introduction of field-grown or net house-grown materials as in vitro without proper procedures, low priority given to potato tissue culture activities, and existing laws that are not conducive to seed production. Overall, the study provides a thorough background to the key constraints in Indonesia's potato seed system.

Farm demand for quality potato seed in Indonesia

sudo — Mon, 09 Feb 2015 09:35:52 +0000

FuglieEtAl(2006) FarmDemandQualityPotatoSeedIndonesia.pdf

One of the major constraints facing crop production in developing countries is a lack of low-cost, quality seed. In this paper, Fuglie et al. present a model of the market for seed, in which clean seed is treated as a capital good providing benefits over several seasons. To determine the farm demand for clean seed, they then apply this model to potato seed in Indonesia. The research uses data gathered from a survey of 182 potato farmers in the major potato growing areas of the country. Findings show that Indonesian potato farmers are well aware of the value of quality seed in potato production, but the high cost (three to four times the price of seed purchased through the informal system) remains a major constraint. Nevertheless, marginal returns to disease-free seed appear to significantly exceed marginal costs, indicating that improving supply of quality seed will contribute strongly to productivity growth in potato. The authors discuss several policy options to encourage supply and utilization of quality potato seed, asserting that the potato seed system cannot be isolated from support for potato breeding and crop improvement generally.

Optimalising potato productivity in Sembalun Highlands, Nusa Tenggara Barat-Indonesia

sudo — Mon, 09 Feb 2015 09:35:52 +0000

HidayaEtAl(2010)OptimalisingPotatoProductivitySembalunHighlandsNTB.pdf

This article presents the findings of a study to help farmers develop optimal potato yields in the Sembalun Highlands—an isolated area of West Nusa Tenggara province without specialist potato support services. The author's assumption was that utilizing a less costly potato system would increase the ability of small farmers to take up potato production. The research was carried out in six farmers' fields involving six farmer-initiated learning groups, who compared the use of superphosphate with local compost. The results show that there was no significant difference in yields using 300 and 600 kg/ha of superphosphate, which produced 33.0 and 33.1 t/ha, respectively. Likewise, there was no significant difference in yield using compost treatments at 3,000kg/ha and 5,000 kg/ha, resulting in 33.0 and 32.7 t/ha, respectively. As a result, farmers can reduce costs and increase income by improving efficiency in input use. An added benefit of this research is the capacity building of local farmers and extension workers, who are now equipped to plan and coordinate simple potato experiments.

This report details the outcomes of work undertaken in West Java, Central Java, West Nusa Tenggara and South Sulawesi to develop potato and cabbage integrated crop management systems, develop and improve farmer access to quality potato seed and build capacity for adaptive research and development. The report details the results from surveys of 80 potato and 50 cabbage crops covering crop agronomy, yield, economics, post-harvest management and potato seed supply, source and quality. It outlines the constraints to potato and cabbage production, with low soil pH being the major constraint. A modified farmer field school participatory technology transfer process facilitated farmer testing of a range of crop management techniques (potato late blight and clubroot management, liming), which is discussed in the report. Soil testing identified the Sembalun Valley as free of potato cyst nematode (PCN) for the potential development of a partial PCN free seed supply using seed imported from Australia. The impact of the project was assessed through farmer surveys, which identified a number of production, financial, environmental, social and gender impacts.

Factors influencing a farmer's decision to purchase seed potatoes in East Java

sudo — Mon, 09 Feb 2015 09:35:52 +0000

AjiEtAl(2001)FactorsInfluencingFarmersDecisionPurchaseSeedPotatoesEastJava.pdf

This article explores the factors that affect a farmer's decision to purchase seed potato in East Java. The research draws on a survey of 209 farmers from three central production areas: Pasuruan, Probolinggo and Batu Malang. Farmers were asked to rate the importance of 34 variables believed to influence a farmer's decision to purchase seed potatoes. The results reveal that the availability of seed at planting time, along with the availability of resources such as land and labour, are the most important factors influencing farmers' decisions to purchase seed. The lack of good quality seed available at planting time means that farmers are often forced to plant whatever seed is available. As a result, farmers typically use their own seed—retaining around 15-20 per cent from the previous harvest—until it degenerates. Only then do farmers tend to purchase improved seed. Given that demand for potato seed in Indonesia outstrips supply, potato farmers still rely heavily on high quality imported seed. However, the high cost of imported seed means that most farmers buy seed from their local supplier that has been multiplied several times.

Integration among regional vegetable markets in Indonesia

sudo — Mon, 09 Feb 2015 09:35:52 +0000

FirdausGunawan(2010)IntegrationAmongRegionalVegetableMarketsIndo_IPB.pdf

In this paper, the authors explore the level of market integration among regional vegetable markets in Indonesia and the movement of prices at the producer and wholesale market levels. Studying price integration among regions is important in order to increase the marketing efficiency of vegetables in the country. The main vegetables included in the study are shallots, large red chilli, potatoes, cabbage and tomatoes. The research uses secondary time-series data from 2001 to 2008 and analyses variables and integration using co-integration analyses. While results from the analyses vary as to whether producer prices do integrate with the reference market, they both indicate that the large red chilli commodity should receive more attention as market efficiency has not yet been reached. The authors suggest that government intervention, especially in the form of pricing policies, is needed both at the producer and consumer level to stabilize vegetable prices in Indonesia. However, the success of this intervention depends heavily on government's understanding of price transmission in the vegetable market. This research makes a solid contribution to this end.
