“…Soils used for vegetable cultivation, however, vary greatly with location and cultivation systems. They may vary from rather acid, low fertility soils, low in organic matter, of alluvial origin, such as around Hanoi (Everaarts et al, 2006), to rich, well-drained, neutral soils with high organic matter and volcanic origin as in the highlands of Java (Thrower and Dudal, 1956). Cultivation of vegetables is often on raised beds, to facilitate surface drain-off during heavy rainfall and furrow irrigation during dry periods (Everaarts et al, 2006).…”

“…When deemed large enough, seedlings are uprooted by hand, selected for size and the absence of pests and diseases, and planted by hand in the production field. Field observations in Vietnam show considerable variation in uniformity and quality of transplants (Everaarts et al, 2006). Different sizes or weights of seedlings and different degrees of transplant shock will decrease crop uniformity.…”

A description of the characteristics of vegetable production in tropical Asia is presented. The description is followed by a discussion of the opportunities and constraints of improved non-seed vegetable production technologies. Sowing of seeds and seedling emergence, transplant production, irrigation, mulching, fertiliser use, crop protection and weed control methods, protected cultivation and harvest date planning are discussed in relation to their use and impact. Conditions for successful introduction of new technologies and the role of outside actors are discussed. It is argued that in order to increase the success of adoption of improved technologies, farmers and public and private institutions should work together. With increasing prosperity, the demand for vegetables, especially in the expanding urban areas, will increase, leading to the intensification of production and higher profitability. With better profitability, the application of mulch, drip irrigation, fertigation and protected cultivation will become more common. With increasing production, harvest date planning as related to year-round city market demand, will become essential to improve profitability. It is recommended that, next to the development and introduction of improved production technologies, research and extension on vegetables in tropical Asia, should also focus on methods to improve harvest date planning and year-round supply.

“…Lowlands. The cultivation of vegetables in the November-March season in the lowlands is often practised in rotation with rice during the summer season, resulting in less than optimum conditions for the growth of vegetable crops (Everaarts et al, 2006). This constraint is likely to be alleviated by permanent vegetable cultivation.…”

A discussion is presented about the patterns in the present year-round supply of vegetables to large cities in the Red River Delta in North Vietnam. Especially during the hot summer season, vegetables are supplied from Dalat in South Vietnam or from Kunming Province in China. Generally speaking, importing vegetables from far away areas or foreign countries adds considerable cost to the product, while extensive transportation decreases product quality or limits the number of products that can be supplied. Aiming for more attractive consumer pricing, an increase in product quality and year-round product availability, options are explored for the regional year-round supply of vegetables from North Vietnam itself. The discussion is based on the agro-ecology of vegetable crops, on market opportunities during the year and on environmental considerations. It is argued that most of the vegetables presently available in the Red River Delta can be supplied from areas in North Vietnam itself. Special attention is given to environmental considerations to ensure sustainable production.

“…In the Red River Delta (RRD), Vietnam, vegetables are mainly grown in a rotation with two consecutive flooded rice crops per year [4]. This vegetable production system in the RRD has disadvantages, e.g., seasonality of production and prices [5,6], poor soil conditions for vegetables, and high labor requirement for land preparation [7]. There also are year-round vegetable production systems in the RRD.…”

Performance of Permanent Vegetable Production Systems Designed with the PermVeg Model for the Red River Delta, Vietnam

The aim of the research described was to design permanent vegetable production systems for the Red River Delta in Vietnam. Permanent vegetable production systems better meet the increasing consumer demand for vegetables and may increase farmers’ income. Optimum crop sequences for permanent vegetable production in the Red River Delta were designed with the recently developed model PermVeg. The crop sequences designed were tested in a field experiment from May 2007 to May 2009. The production systems tested were five systems designed according to the scenarios of (i) high profitability, (ii) low labor requirement, (iii) low costs of pesticide use, (iv) high level of crop biodiversity, and (v) low perishable products, respectively. The five systems were compared with the traditional vegetable production system. At local prices, only the high profitability and low labor requirement systems yielded significantly higher profits than the traditional system. At city wholesale market prices, profits of all permanent vegetable production systems were significantly higher than that of the traditional system, except for the low perishability system. Permanent vegetable production systems required more labor than the traditional system. Labor-day incomes of permanent vegetable production systems generally were not higher than those of the traditional system. The labor-day income increased only with the low labor requirement system at city wholesale market prices. The model outcomes correlated reasonably well with the labor requirement and the length in days of production systems in the field. The model poorly predicted profits and costs of pesticide use. We concluded that permanent vegetable production systems can yield higher profits than the traditional system, and can contribute to enhancing employment opportunities and increasing household income.
