A Study on the Use of EM Treated Pig Waste Water for Vegetable Growing

Abstract

The study was objected to determine the use of EM treated pig waste water and/or EM treated pig manure as sources of plant nutrients in comparison with chemical fertilizer and EM fermented compost. A series of pot experiments were conducted to evaluate yields and yield components of kale, Chinese radish, chilli and marigold. Expeimental results showed that yields of kale grown with EM treated pig waste water and/or EM treated pig manure were significantly lower than for chemical fertilizer. In chinese radish and chilli, crop yields receiving combination of EM treated pig waste water and EM treated pig manure were not significantly different from those using chemical fertilizer. In marigold, flower weight per plant was higher for EM treated pig waste water than for chemical fertilizer while the yield value for EM treated manure was comparable with that for chemical fertilizer.
