This paper reports on three experiments evaluating Japanese tomato varieties for use in Indonesia. The experiments evaluate these varieties based on yield comparisons with the standard Indonesian variety, fruit characteristics for fresh and processing and seedling growth using three low cost, locally sourced seedling raising media. Results of each experiment are reported and discussed separately. The paper details the yield differences and summarises fruit characteristics including discussion of suitability for fresh or processing sectors.

This study reports on the effects of different growing practices and aspects on True Seed Shallot (TSS) production in Java. The study comprises a range of experiments which are listed in the introduction. These encompass early sowing and transplanting, optimal nitrogen fertilisation, optimal plant density, seed efficiency, optimal age and nitrogen status of nursery, TSS under insect nets and bulb storage quality. Each experiment is briefly reported in a separate section and comprises methodology, results and discussion.

Traditional Indonesian shallot production is based on seed bulbs but True Seed Shallots (TSS) could improve competitiveness of the industry. This study assesses numerous factors such as, seed raising mixtures, sowing depth and furrow fill, productivity comparison of TSS cultivars and seed bulb cultivars, plant density and nitrogen fertilisation, for their impact on shallot growth and production. Each experiment is reported on and discussed separately.

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 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.

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.

This report identifies intervention opportunities to strengthen the performance of the vegetable sub-sector in Eastern Indonesia. The research is based on field observations, interviews with value chain participants and consultation with other stakeholders in West Java, East Java, Central Java, Bali, South Sulawesi and North Sumatra. The report contains a summary of the vegetable sub-sector and an outline of private and public sector roles.

This paper provides a useful overview of government policies and regulations relating to the seed industry covering the early stage of the formal seed industry, seed trade, seed certification, crop varieties protection and seed producer's registration. Seed policies are generally renewed by the government along with progress in the seed industry. The paper also assesses the conduct of the National Seed Agency and its related institutions in controlling production and marketing of corn seed in East Java.

Maize yields in West Timor average around 2 t/ha, but have the potential to reach more than 4 t/ha with improved varieties, agronomy and nutrition. This paper explores the agronomic and physical characteristics of West Timor's landrace maize and production systems to determine the best approach for improving maize production and yield in West Timor. The research trials five maize varieties—three West Timor landrace populations and two open pollinated varieties—and grows them in the villages of Benlutu and Mnelalete in East Nusa Tenggara.
