Efficieny of Vegetables
One factor to consider when planting and growing vegetables is the amount each plant will yield. Some plants, such as tomatoes and basil, yield a larger amount than others, while certain squash and melons yield a small amount per square foot. Of course, with melons and pumpkins producing larger fruit, this is somewhat proportional. Nevertheless, the National Garden Bureau rates all common crops on a scale of one to ten on efficiency, or the amount of fruit a plant yields per foot. When planning your garden, this will help you decide the amount of plants you’ll need and which plants would suit your needs. No plant is a perfect ten, but here are ratings for all basic vegetables:
- Tomatoes – 9
- Green onions – 8.2
- Leaf lettuce, turnips – 7.4
- Summer squash – 7.2
- Onions with bulbs, peas – 6.9
- Beans, grown on a pole – 6.8
- Beets – 6.6
- Carrots; beans, grown in a bush; cucumbers – 6.5
- Sweet peppers – 6.4
- Broccoli, Swiss chard, kohlrabi – 6.3
- Mustard greens, spinach – 6.2
- Lima beans, radishes – 6.1
- Cabbage – 6
- Leeks – 5.9
- Collards – 5.8
- Okra – 5.7
- Kale – 5.6
- Cauliflower, eggplant – 5.3
- English peas – 5.2
- Brussels sprouts, celery – 4.3
- Melons, winter squash – 3.8
- Pumpkins – 1.9
