We compared the performance of three vegetable production systems using one variety each of tomato ‘Money Maker’ and capsicum ‘New Ace’ in two hot and seasonally dry lowland locations of Central Province, Papua New Guinea. The three systems used were Traditional farmer’s practice (TFP), improved production systems (IPS) and commercial high input practice (CHIP). TFP was based on traditional techniques using local knowledge and system descriptions from other earlier work; IPS supplemented the traditional practice with low cost technologies and practices expected to produce high returns and; CHIP employed techniques and technologies likely to be obtainable by few farmers due to high fixed and working capital requirements and other barriers. In the traditional system pest and disease infestation were high, and responsible for lower fruit quality and yield than In IPS and CHIP. IPS produced crop yield and quality comparable to or better than that of CHIP, indicating that the use of additional low cost technologies and practices in the TFP may enable higher production and create opportunities for smallholder farmers to increase their disposable cash income. The results are discussed in context of the Improved Practice vegetable production system being adopted by smallholder farmers and community cooperatives in the Central Province, Papua New Guinea, and how these improved systems should be able to contribute to vegetable supplies for major local markets, especially Port Moresby.
