Cultivation management

The relative humidity in the center of origin of cumin is rather low. High relative humidity (i.e. wet years) favors fungal diseases. Cumin is especially sensitive to Alternaria blight and Fusarium wilt. Early-sown crops exhibit stronger disease effects than late-sown crops. The most important disease is Fusarium wilt, resulting in yield losses up to 80%.Fusarium is seed- or soil-borne and it requires distinct soil temperatures for the development of epidemics. Inadequate fertilization might favor Fusarium epidemics. Cumin blight (Alternaria) appears in the form of dark brown spots on leaves and stems. When the weather is cloudy after flowering, the incidence of the disease is increased. Another, but less important, disease is powdery mildew. Incidence of powdery mildew in early development can cause drastic yield losses because no seeds are formed. Later in development, powdery mildew causes discolored, small seeds.
