Full TextAbstract
The effects of various fertilizers and different compost extracts on crop health and tomato yield were studied in the field in 2004-2005 in two locations in Iran. Treatments included different fertilizers (cattle, sheep and chicken manures, green-waste and house-hold composts and chemical fertilizers) and five aqueous extracts (from cattle manure, chicken manure, green-waste and house-hold composts and water as control). The effect of fertilizer type on tomato yield was significant in both locations (P<0.05). Organic fertilizer use did not obtain higher yields compared to using chemical fertilizer. Generally, chicken manure and green-waste compost led to the highest and lowest tomato yield among different organic fertilizers, respectively. The effect of aqueous extracts was not significant on either crop health or tomato yield with these results were being very limited and inconsistent. Improved efficacy of acceptable alternatives to agrochemicals, especially in organic farming, is required.
