I. INTRODUCTION
Vegetables: crops which cannot lack and be replaced in daily diet of human.
Vegetables provide lots of vitamins, proteins, lipids, minerals and photochemicals… that other foods cannot be replaced
Vegetables are plants with high economic efficiency The area and production of vegetables in the worldwide and
Vietnam have continued to increase

NUTRITIVE VALUE IN TOMATOES
Vitamins: Carotenoid ( 1-2 mg%), C (20-40 mg%), B1 ( 0.08-0.15 mg), B2 (0.05-0.07 mg), PP (0.5-1.65 mg).
Minerals: K (114-207 mg%), P (23-36 mg), Na (8-45.8 mg), Ca (7-20 mg).
Carbohydrate: 50% of dry matter, 2-4% of fresh weight. Organic acids: citric acid, malic acid occupy 12-13% dry matter, 0.4-
0.6% of fresh weight. Lipids occupied 24% of seed weight. Tomatoes can be eaten by cooked or raw.

Dang Xa is a commune in Gia Lam district where the natural area is 587 ha, occupying 486 ha of arable land.
Dang Xa has favorable geographical location, infrastructure and natural conditions for tomato production.
However, actual production of tomatoes here still faces to many difficulties such as fragmented and small producing state, do not follow regulations, consumer heterogeneity and uncertain.
From the above situations, we carried out the research : “Production and consumption of tomatoes in Dang Xa - Gia Lam – Ha Noi”.

II. PRODUCTION AND CONSUMPTION OF TOMATOES
2.1. Soil type and cultivation techniques.
+ Dang Xa commune soil mostly is sandy loam
+ Before planting farmers must clean weeds and plow carefully
+ After making soil small, make the planting beds, then mix manure and phosphorus (or NPK) into the soil, after that put into each plant hollow
13
Make the planting bed:
- In rainy season: narrow and high bed with bow-shape
0.7 – 0.8m wide, 30-35cm height
- In dry season: wide and flat bed with sag shape
1 – 1.2m wide, 20 – 25cm height, furrow 30 – 35cmSpacing: - row-row: 70cm
- plant – plant: 55 – 60cm Plant populations: 1000 – 1200 plants/sao

2.2.Growing season: + Summer – Autumn: May - Jul. + Early Winter – Spring : Jul. - Sep. + Mid Winter - Spring : Sep. - Nov. + Late Winter - Spring : Nov. - Jan. + Spring – Summer : Jan. - Apr.
16
2.3. Crop rotation formula:
+ Formula 1: Cabbage (Oct. – Feb.) – Tomato (Feb. – Jun.) – Yard – long bean (Jun. – Oct.)
+ Formula 2: Sweet potato (Jan. – May) – Soybean ( May – Aug.) – Tomato (Sep. – Dec.)
17
2.4. Fertilizer Applied amount per 1 sao: manure, 3- 4.5kg P, 5.2- 5.6kg
N, 5- 5.6kg K Basal application: 100% manure+ 100% phosphorus
fertilizer (compost or NPK), fertilizers are spread on the soil of bed.
Top dressing: applies N, K in 3 – 4 times during main growth stages. Each time includes 1.3 -1.4kg N ; 1.25–1.4kg K
- First application: 10-15 days after transplanting.
- Second application: starting to flower.
- Third application: flowering and fruit setting.
- Last application: after first harvesting.
18
2.5. Watering.
- After planting, farmers watering tomatoes in the morning or afternoon
- Watering should be frequently and throughout.
- Farmers can combine with fertilizer application.
- Furrow irrigation should be applied in critical periods (flowering and fruiting stage).
- Overall the canal and ditch system in the local are still low
- In winter, lack of water to irrigate vegetables, therefore should upgrade to the irrigation system adjusted to suit the amount of water needed.
19
2.6 Weeding, break and turn up the soil
+ Farmers in the local knew the importance of weeding, cultivating.
+ Break and turn up the soil: usually 2 times before staking.
- First time: After planting about 10-12 days, when the trees are rooted, combined with weeding and first top dressing.
- Second time: about 1 month after planting.
20
2.7. Pests and diseases
a. Pests:
- Leafminer: occurs early in the fruiting period, defoliation can reduce yield and fruit size and expose fruit to sunburn
- Fruitworms: consume the tomato’s interior and leaves, a cavity filled with fluid and droppings. The tomato quickly decays and rots.
- Thrips: feed on the lower surface of leaves, buds, flowers and fruits; also are vectors of the tomato spotted wilt virus.
- Whiteflies: Leaves may dry out and turn yellow, and tomato growth will be stunted.
21
b. Diseases:
- Bacteria wilt: Affects to all stages but most serious during reproductive stage and fruiting stage.
- Late blight: can infect and destroy the leaves, stems, and fruits tomato plants.
- TYCLV: can be easily recognised when tomato plants are infected at the seedling stage. TYLCV causes severe stunting of young leaves and shoots.
- Powdery mildew: White, powdery spots appear on leaf surfaces, spreading to cover leaves and even stems. The leaves will then turn yellow, die and drop off. Plants will have a lower yield and shortened fruiting season. The fruits have less flavor than healthy fruit.

METHODS TO CONTROL
Farmers early detect these diseases and find the appropriate control methods.
Limit using of chemicals pesticides as drugs can kill natural enemies that are useful in crop fields.
Farming practices to remove crop residues after harvesting
Plowing soil deeply (10-15 cm), exposed to the sun from 10-15 days before planting
Farmer should do seed treatment before sowing and watering to avoid harmful moisture for the roots.
Applying crop rotation and thinning
25
HARVESTING AND CONSUMPTION Harvest at right maturity and at right time Pick fruit carefully to avoid mechanical injury Productivity: >3kg / plant. After harvesting, tomatoes are sold out to traders at the farm or
retail markets, no seeds remain for next season. Price fluctuates from 5000 – 9000 VND/kg Mid Winter-Spring: harvest on the Lunar New Year period so price
in this growing season is the highest reaching 15,000 VND / kg.

3. ADVANTAGES AND DISADVANTAGES IN PRODUCTION
1. Advantages:
- Farmers in Dang Xa: a long tradition of growing vegetables, many experiences in production, and hardworking.
- Soils with a light mechanical is advantaged for the cultivation
- Demand of vegetables is increasing.
- Location of tomato production has convenient transportation
- Dang Xa commune is located in the suburban of Hanoi to provide tomatoes consumed within the city and surrounding areas.
28
2. Disadvantages:
- Natural disasters: such as hurricanes, floods, frost, fog...
- Farmers are dependent on weather conditions
- Awareness of farmers is limited about fresh vegetables issues,
using pesticides indiscriminately
- Capital of households is limited.
- Lack of good quality seeds.
- Plant structure is unsuitable
- Lack of uniformity, specifically each household plants different
crops on the same 1 unit area leads to considerable care,
technical progress can not be applied simultaneously.
29
4. SOLUTION CONTRIBUTE FOR DEVELOPMENT
Farmers should focus on the investment for techniques, resulting in a brand safe vegetables for consumers to know and trust.
Open technique training programs to help farmers access to scientific and technical progress and apply in production.
Government should increase investment on financial inputs to farmers so they can invest for their production.
30
Dang Xa is conveniently located in the transport and consumption of vegetables in the Hanoi area so should actively find markets for farmers.
Applying the technical equipment: house roof, low arch or specialized nets.... which are cheap materials, suitable conditions of each household.
Updating good varieties, suitable with the natural conditions of the area.
Constructing of infrastructures such as irrigation systems, roads…
31
IV.CONCLUSIONS
Natural conditions, socio-economic, market demand etc. in Dang Xa commune, Gia Lam, Ha Noi are quite favorable for development of vegetable production in general and tomatoes production in particular.
Price of tomatoes in still unstable Production system stops at small, unbranded household level
which limits the prestige and consumer markets.
32
SUGGESTIONS
The solutions to developed vegetable production, especially the production of safe vegetables should be implemented uniformly: management agencies to organize production and supply.
Raising proficiency, technical to farmer by opening the technical training on vegetable cultivation…
Using the technical methods for safe vegetable production to improve quality, productivity and income for farmers.
Building the storehouses for storage equipments of agricultural products in the local.
