RESEARCH ON CULTIVATION POTENTIALITIES OF 'LOCAL KARACADAG' AND 'OSMANCIK-97' RICE VARIETIES IN ORGANIC AGRICULTURAL CONDITIONS

This research was conducted to determine the potentialities of organic rice cultivation in Karacadag region and to set an example for farmers in transition to organic farming. The Local Karacadag paddy the variety grown in the Karacadag region and the Osmancik-97 breeding variety, the most cultivated variety in Turkey, were used as material. The research was carried out in three replications according to the split parcel trial design in random blocks in the 2011-2012-14 rice growing periods on the farmer field in Karahan village of Karacadag region, in Turkey. As a result of the agricultural researches made, organic values showed superior rates compared to conventional applications in terms of the number of days of flowering (92.3 days) and non-fractured rice yield (65.6%). It was observed that regarding the kernel yield in unit area the Karacadag variety was highest at 4 816 kg ha(-1) in the conventional application while the organic application of the Karacadag variety was in second place with 4 179 kg ha(-1). It is concluded that the organic rice farming is thought to be economical when the organic rice in the market is sold with about 30% more the price compared to the conventional rice.
