Response of Asparagus to Applications of Simulated Vegetable-Processing Waste Water1

  1. George A. Pearson2

Abstract

Abstract

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.
