Create a chart comparing the efficency and suitability of different irrigation methods for vegetable crops.
Irrigation Method | Water Use Efficiency | Suitability for Vegetable Crops | Advantages | Disadvantages |
---|---|---|---|---|
1. Flood | Low | Onion, garlic, pea, spinach, coriander, fenugreek and amaranthus | Applicable to leveled soils, low operational cost using gravity, no need for skilled labor, and no specialized equipment required. | Unscientific method with high water loss, uneven water distribution, increased weeds, nutrient loss, and unsuitable for certain crops. |
2. Border | Low | All vegetable Crops | Easy to prepare, operate, and maintain; suitable for irrigating crops on steep slopes using small strips. | Needs flat land, high water flow, not suitable for sandy soil, and requires proper drainage to prevent waterlogging. |
3. Check Basin | Moderate | Bitter gourd, bottle gourd, ridge gourd, melons, etc. | Suitable for irregular fields with high water application and distribution efficiency. | Requires proper leveling, more labor, hinders farm machinery use, and not suitable for waterlogging-sensitive crops. |
4. Furrow | Moderate | Tomato, brinjal, potato, chili, radish, carrot, cauliflower, etc. | High water efficiency, fewer weeds, low cost, easy to use, less labor, low evaporation, and suitable for most soils. | More labour needed, hinders machinery, and not suited for sandy or uneven land. |
5. Sub-surface | Moderate | All vegetable Crops | Less water loss, no interference with farm work, and easy water level control. | High installation cost, hard to find leaks, costly repairs, and not suitable for crop germination irrigation. |
6.Sprinkler | High | All vegetable Crops | Works on uneven land, saves water, supports farm tools, allows input use, covers more area, and protects from frost. | High cost, affected by wind, unsuitable for salty water, needs skilled labor, and not ideal for tall, widely spaced crops. |
7. Drip | Very High | All vegetable Crops | Saves 40–60% water, boosts yield, reduces weeds and labor, delivers fertilisers to roots, and suits hilly areas. | Very costly, needs regular care, requires technical skill, and not suitable for salty water or soil. |
