Total land area and cultivation
Rice cultivation 54% (2,650,995ha)
Fruit production was 89,981 ha.
Vegetable was 42,360 ha.
The flower land area in Cambodia in Non :
- We have a little plant in a round house
- Most of flower import from out side the country
- The use of flower in Cambodia for many possible ways advantage like:
Decoration, Using at wedding ceremony, Providing to the god in the Pagoda, any
celebration, souvenirs, and love.
- The flower import by the private business is the plays full role in the present.
- And now Cambodia just little a new technology of this field like grafting : bring of

Introduction
The 3 main objectives of applying postharvest technology to harvested fruits and vegetables are:1. to maintain quality (appearance, texture, flavor and
nutritive value)2. to protect food safety, and3. to reduce losses between harvest and
consumption.

Postharvest Handling
• Farmers deliver produce to collection centre
• Produce is dispatched to Packing House
• Produce is cleaned, trimmed, sorted, packed and randomly tested for chemical residue
• Handling is according to GMP and HACCP standard
• Heat-sensitive produce stays in ‘cold chain’
![Page 15: 24 provinces/towns 185 districts 1,621 communes over 13,000 villages Total population over 14 million Country Profile](https://reader030.vdocuments.net/reader030/viewer/2022032701/56649c9b5503460f94958846/html5/thumbnails/15.jpg)

Principal causes of postharvest losses and poor quality
The most common causes of postharvestlosses in developing countries continue are:• Rough handling • Inadequate cooling and temperature
maintenance• Lack of sorting to eliminate defects before
storage• The use of inadequate packaging materials

Step related to contaminate
• Pre-harvest conditions• Pre-harvest handling• Packing/packaging• Transportation• Retail handling• Consumer handling

Sources of Contamination• Rain• Irrigation water• Soil• Physical handling• Field storage• Washing• Packing• Transportation• Handling at the retail shop• Handling by the consumers
![Page 20: 24 provinces/towns 185 districts 1,621 communes over 13,000 villages Total population over 14 million Country Profile](https://reader030.vdocuments.net/reader030/viewer/2022032701/56649c9b5503460f94958846/html5/thumbnails/20.jpg)
Methods to reduce or eliminate contamination
• Avoiding physical contact at harvest.• Avoiding using contaminated water or reusing
water.• Treating the fruits or vegetables with ozonate
or chlorine water. • Cleaning the packing containers with bleach if
it is reused. • Avoiding exposure to high temperature.

• Cleaning the trucks with bleach.• Packaging the fruits and vegetables to avoid
physical contact. • Reduce water loss• Preventing handling of produce by the
consumers• Cooling/refridgeration /cold storage• Waxing and treating with fungicides• Irradiation

• In many, but not all, Asian countries, the standard of retail markets is very poor.
• Problems in markets include:– Poor sanitary conditions. Arrangements for waste
disposal are frequently inadequate.
Factors affecting quality and safetyof horticultural products in retail marketing
![Page 24: 24 provinces/towns 185 districts 1,621 communes over 13,000 villages Total population over 14 million Country Profile](https://reader030.vdocuments.net/reader030/viewer/2022032701/56649c9b5503460f94958846/html5/thumbnails/24.jpg)
–Washing. water used should be clean and be changed frequently.– Fungicide and insecticide application. Farmers
and traders sometimes spray insecticides directly on to fruits and vegetables to keep insects off the produce.

–Ripening. In Cambodia and some countries still use calcium carbide to ripening of bananas and mangoes, although in India it is technically banned as it contains impurities, including arsenic hydride. Much ripened fruit has an unsatisfactory flavour or aroma because it has not reached maturity before harvest, eg. Tomato.

– Exposure of produce to ambient conditions. Markets in many countries lack shelter and produce is exposed to direct sunlight and rain. Temperatures of the display tables or refrigerated supermarket displays should be suited to the commodity on sale. For example, while peppers and tomatoes look pleasing when displayed with lettuce, peppers and tomatoes are chilling sensitive, while lettuce is not, so that peppers and tomatoes will be spoiled.

– Poor packaging materials and practices. Produce is often moved between markets using second-hand packaging.
– Sorting and trimming. At wholesale and retail stages trimming of leafy vegetables is carried out. Sorting and trimming is frequently done on the ground, in the sunlight.

- Retail display on the ground. Even in those that do have good facilities retailers sometimes prefer to display their produce exposed on the ground, in areas that they believe attract the most customers.

–Handling by retailers and consumers. Many retail markets lack toilets or suitable washing facilities, leading to poor hygiene for traders. Produce on display is often picked over by consumers. This can lead to bruising and contamination of the produce.

StorageIn Cambodia generally improper storage fruits and vegetables.

Transportation in CambodiaIn Cambodia generally there is no standard transportation for transporting fruit and vegetable such as vehicle (van, truck, taxi), boat, motorcycle, bicycle, horse cart.

Problems and Challenges • Small scale production & lack of irrigation system• Seasonality produce• No application of postharvest and technology • Lack of credit or microfinance (saving group)• Competition with import product (price and quality)• Disperse production• Less processing • Lack of market information (farmer)• Market for agriculture is limited which is a serious threat for
investor• Producer s’ education limited on agricultural production• Late of improvement of new technologies in product system
![Page 33: 24 provinces/towns 185 districts 1,621 communes over 13,000 villages Total population over 14 million Country Profile](https://reader030.vdocuments.net/reader030/viewer/2022032701/56649c9b5503460f94958846/html5/thumbnails/33.jpg)
Opportunities
• High domestic demand though expensive• High demand for agriculture quality product at the
local and international market• Abandon land• Development of technologies of product system as well
as postharvest technologies and food processing• High potential in agriculture base on resource, climate
and adapting climate change• Productivities increasing by enlarge of product area
through land concession for agricultural investing• Human resource development• Have many stakeholders involve
![Page 34: 24 provinces/towns 185 districts 1,621 communes over 13,000 villages Total population over 14 million Country Profile](https://reader030.vdocuments.net/reader030/viewer/2022032701/56649c9b5503460f94958846/html5/thumbnails/34.jpg)
Opportunities
• Enlargement of production areas• Government policy support and priority • Increase linkage among public, private sector
and NGOs in extension• Decentralization and de-concentration policy
and process.• Availability of promising technologies within
Cambodia and outside.
![Page 35: 24 provinces/towns 185 districts 1,621 communes over 13,000 villages Total population over 14 million Country Profile](https://reader030.vdocuments.net/reader030/viewer/2022032701/56649c9b5503460f94958846/html5/thumbnails/35.jpg)
Conclusion and Recommendation• Bargaining power of the Cambodia farmers/growers is still
very low• Poor marketing information system• Less working capital for all actors in the supply chain• No subsidy, high risk, little intervention• Marketing share for farmers is still low• Upland crops and vegetable crops draw less attention than
rice crop• Stakeholders must be trained and be made aware of these
changes in order to participate effectively in fresh produce supply chains.
![Page 36: 24 provinces/towns 185 districts 1,621 communes over 13,000 villages Total population over 14 million Country Profile](https://reader030.vdocuments.net/reader030/viewer/2022032701/56649c9b5503460f94958846/html5/thumbnails/36.jpg)
Conclusion and Recommendation• Stakeholders must be cognizant of environmental issues in
selecting packaging options• Contract farming is increasing and has to be supported• Should promote the drying machine service and postharvest
technology for vegetables crops• Improve coordination and dialogue between the government
and the private sectors• Reduce as much as possible the processing and transport cost • Governments should pay more attention to pesticide ,
microbial and parasitic contamination issues. Ways of reducing such contamination need to be identified and information widely to farmers and traders.
• Further research on the causes of contamination during production and marketing is recommended.
