Karacadağ Koşullarında Konvansiyonel ve Organik Çeltik Yetiştiriciliğinin Araştırılması

Organic production is not only sustainable agriculture, but also an alternative production model that aims to produce quality and healthy products. The present work was conducted to define the potentialities as economic of organic rice cultivation. The Osmancık-97 and Karacadağ cultivars, were used in the research. The research was carried out in three replications according to the split parcel trial design in random blocks rice growing periods on the farmer field in Karahan village, in Diyarbakır. According to the results obtained from the research; fertility was 83.5-91.2%, harvest index was 35.7-36.5%, and number of weed varied between 1.94-3.28 number/m². The values of grain yield of the Karacadağ cultivar was 4816 kg ha-1 and 4179 kg ha-1 in conventional and organic conditions while the values of grain yield of the Osmancık-97 cultivar was 3784 kg ha-1 and 3234 kg ha-1 in conventional and organic conditions, respectively. The local variety Karacadağ gave the best results for all the traits tested. Economically, organic Karacadağ application was regarded to be the most profitable method with a net profit of 3761 TL ha-1. Karacadağ variety has proven its adaptability to Diyarbakır ecological conditions. It is concluded that organic production in the region can be increased by using Karacadağ paddy in organic cultivation.
