Abstract only
Chickpea is an important source of protein in many developing countries in different parts of the world. In Turkey, it is the most important grain legume crop grown under diverse agro-climatological conditions in various parts of the country. The yield of chickpea is about 1000 kg/ha and its increase is hindered by various biotic and abiotic stress factors. Amongthe biological constraints, ascochyta blight (Ascochyta rabiei) is the most important disease, determining the production practices (Dusunceli et al., 2003). The disease can occur in all parts of the country, and in humid springs it can cause total yield losses to susceptible cultivars. Although seed treatments and foliar sprays may reduce the disease severity, fungicide application is not practiced due to a number of disadvantages. Therefore, development of alternative methods for the disease control is essential. This initiative has been designed to develop non-chemical integrated disease management (IDM) procedures for application in the Central Anatolia. The studies have been carried out at the research farm of the Central Research Institute for Field Crops (CRIFC) in 3kizce, Haymana (1050 m) 45 km to south-west of Ankara, Turkey. The components of the study included screening of germplasm for resistance to develop ascochyta blight resistant cultivars, iden- tification of appropriate soil tillage methods to reduce the effect of diseased plant debris in disease development, determination of the most appropriate sowing date for the recommended cultivars to avoid disease occurrence and establishment of a disease management protocol. The study facilitated determination of level of resistance of the registered cultivars and ger- mplasm developed under the chickpea-breeding programme of the CRIFC. The study also showed the importance of deep tillage for the burial of diseased plant debris and advantages of use and early sowing of cultivars with resistance to ascochyta blight, as well as disadvantages of use of susceptible cultivars and late sowing. Through the study, essential non-chemical procedures have been identified for the establishment of an efficient integrated disease management protocol for controlling Ascochyta rabiei in chickpea. The study has been supported by the European Union ( contract CA4-CT -2000- 30003).
