Response of Asparagus to Applications of Simulated Vegetable-Processing Waste Water1
- George A. Pearson2
Asparagus (Asparagus officinalis L.) might serve as a cash crop in fields to be used for food processing waste water treatment.
An experiment was conducted to determine the suitability of asparagus in such a situation. Well water and simulated waste waters representative of pea (Pisum sativum L.), green bean (Phaseolus vulgaris L.), corn (Zea mays L.), lima bean (Phaseolus lunatus L.), and steam-peeled sweet potato (Ipomoea batatas Lam.) processing waste waters were applied at rates of 6.4, 12.7, and 19.0 mm/day, 5 days per week. The chemical oxygen demand (COD) values of the simulated waste waters ranged from 534 to 7,144 mg/liter.
Asparagus yield was adversely affected by the highest COD waste water applied at the highest rate only.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
