Study Notes
Vegetable Crops Production and Management
- Vegetables are plants used as food, including fruits, seeds, roots, tubers, bulbs, stems, leaves, or flower parts.
- Some vegetables are annuals, biennials, or perennials.
- Herbaceous plants have no persistent woody stems.
- Vegetables are diverse in their growth habits (viny, shrubby, or tree).
- Harvested fresh when moisture content is high.
- Vulnerable to damage and cannot be stored long.
Importance of Vegetable Crops in Ethiopia
- Key vegetables in Ethiopia: pepper, Ethiopian mustard/kale, onion, tomato, potato, chili, carrot, garlic, cabbage, green beans, and peas.
- Many smallholder farmers and large-scale commercial producers are engaged in production.
- Smallholder farms average 0.9 hectares.
- Primarily for own consumption, but commercial farms are for the market.
- Significant export to multiple countries.
- Key exported vegetables: tomatoes and chili.
Environmental Factors Influencing Vegetable Production.
- Climate (temperature, light, precipitation).
- Soil (chemical, physical, nutritional status).
- Topography.
- Biotic factors (insects, diseases, weeds).
Temperature Significance in Vegetable Growth
- Affects all steps in plant growth (photosynthesis, respiration, transpiration, germination, and flowering).
- Temperature impacts crop type and yield.
- Vegetable crops have temperature ranges (min, max, and optimum) for successful growth determined by origin region.
Water Importance in Crop Production
- Water is vital for germination and growth of crops.
- Essential for photosynthesis, cell division and maintenance of turgidity.
- Water shortage during critical stages of vegetable growth (early growth stages, flowering, seed setting) negatively affects yields.
Light Significance in Vegetable Production
- Light is crucial for photosynthesis.
- Plants grown in full light are more vigorous, with higher chlorophyll amounts and photosynthetic activity.
- Plants in low light conditions have lower chlorophyll amounts.
Humidity's Impact on Vegetable Production
- High humidity often linked to crop disease and pest incidence.
- Affects plant transpiration, carbon dioxide uptake, and oxygen diffusion through stomata.
- High humidity can cause increased germination of certain fungal species, damaging plant growth.
Altitude and its Effect on Vegetable Production
- Altitude affects temperature and rainfall.
- Increase in altitude correlates to a drop of 0.6 °C in temperature per 100 m elevation.
- This variations in temperature and water requirements is crucial for determining which vegetables will thrive successfully.
- Highlands in Ethiopia are beneficial for producing vegetables with lower temperature demands.
Soil Factors in Vegetable Production
- Soil type affects water storage, drainage, and nutrient levels.
- Soil type dictates whether or not a vegetable crop will grow effectively.
- Compaction and drainage are essential and must be considered before planting.
- Compaction decreases oxygen availability (and water storage).
Classification of Vegetable Crops
- Vegetables are classified according to their roots, leaves, or stems (consumed for food).
- Categorized as:
- Root vegetables (carrot, garlic, radish, cassava, sweet potato)
- Leafy vegetables (spinach, lettuce and cabbage)
- Flower vegetables (cauliflower, broccoli)
Types of Vegetable Production System
- Gathering wild vegetables.
- Growing vegetables within cereal crops.
- Home gardening.
- Commercial vegetable production.
Principles of Vegetable Crop Management.
- Site selection and management.
- Sustainability management.
- Planting material and its adaptation to local conditions.
- Integrated crop management, avoiding dependence on chemicals to control crop pests and diseases.
- Implementing crop rotation in order to improve disease and pest control.
- Water management
- Quality management
- Importance of maintaining soil quality to achieve high yields and quality coffee.
Factors Influencing the Quality of Fruits During Harvest and Post-harvest
- Maturity and correct harvesting time are crucial.
- Handling fruit during harvest and transportation is essential to maximize quality.
- Proper storage and packaging methods reduce post-harvest losses.
Floriculture and Landscaping
- Floriculture is the cultivation of flowering or decorative plants.
- Important flowering crops in Ethiopia: roses, poinsettias, lilies.
- Commercial benefits to Ethiopia: suitable climate and adequate resources.
Root and Tuber Production Management
- Root crops and tubers: underground portions of vascular plants primarily serving as storage organs for nutrients, e.g. beet, carrots, parsnips, cassava, potato, sweet potato and yams.
- Root/tuber crop classification (FAO methodology for categorization.
- Importance of root and tuber crops.
- Potential issues (e.g. diseases/pests).
- Considerations in selection for suitable cultivation types (e.g. drought-resistant crops).
History and Origin of Coffee, Tea and Spices
- Coffee: originated in Ethiopia, with Kaldi's goats leading to the discovery of its stimulating properties. Key coffee types: Arabica, Robusta, and Liberica.
- Tea: originated in China, though now cultivated in various Asian and African countries.
- Spices are aromatic parts of plants used for flavor and coloring.
- Production status and economic importance of these crops.
Propagation of Coffee and other crops
- Coffee Propagation: seed and vegetative methods are prevalent, like cuttings and grafting.
- Tea Propagation: also via seeds, but vegetative methods are most common.
- Important propagation considerations (e.g., cutting, seed processing, planting techniques).
Field Establishment and Management Practices for Coffee
- Land preparation for coffee plantations is essential and must be prepared at least one year in advance of planting.
- Important methods (e.g., hole preparation, soil mixture).
- Field management (e.g. weed control, crop protection, water management and fertility).
