Yield and yield components, and protein content of chickpea (Cicer arietinum L.) were compared in traditional and organic production systems since organic farming has many advantages on environment, animal and human health over traditional production systems. In the study, organic production system, green manure, farmyard manure and effective microorganisms and their combinations were tested as six treatments. Seed yield and some yield components were found higher in the traditional production system than those of organic production systems. The highest protein content was obtained in green manure and farmyard manure applications. Among the organic production systems, green manure and farmyard manure applications could be strongly recommended for organic chickpea producer since the highest seed yields with 2729 in 2007 and 3838 kg ha(-1) in 2008 were found in green manure + farmyard manure treatment among the organic production systems.
