Despite its long history of production and its various uses in the socio-economic setting of the traditional farmers in the highlands of Ethiopia, the productivity of noug (Guizotia abyssinica Cass) is so low, about 340 kg/ha. Sowing dates between late June to early July for the higher altitudes (above 2000 m), and mid to late June for the lower altitudes (below 2000 m) areas in the central zone; mid July for western and southeastern zones; and early to mid July for the northwestern zone were found optimum for the production of late maturing noug type. A range of seed rates had little or no effect on the optimum sowing dates, however, with delayed sowing, higher rates, 10-15 kg/ha are required. Harvesting at three weeks after 50 per cent petal drop minimizes seed loss. Cropping sequence studies confirmed that noug is a good precursor for cereals. The cultivars available to date have photosynthetically less efficient plants whereby some of the lower leaves behave like potential sinks at the time of high demand for assimilation.
