| Abstract | The study was conducted in the glasshouse of the Faculty of Agriculture, University of Khartoum, to evaluate various cultural practices on the development of Rhizoctonia diseases of potato (Rhizoctonia solani Kuhn) during the season 1998/1999. Four cultural practices were applied on two commercial cultivars of potato using factorial design. These treatments were: soil amendment with organic manure, soil exposed to sunlight (solarization), soil flooding and then exposed to sunlight and soil flooded and planted when dried. In the first three treatments, soil was left fallow for 12 months before the planting of potato. Yield reduction due to the soil infestation by the pathogen was 63.96%. The influence of two treatments was significant, particularly in disease suppression and subsequently in improvement of the final tuber yield. Cow manure amendment reduced the sclerotia formation in yielded tubers by 17.04-21.48%. The tuber yield was also improved more than twice as much as using this soil amendment. The practice of soil flooding and exposing to direct sunlight also gave significant results. The ineffective treatment was the soil flooding and planting when dried (without fallow and solarazation). These perspectives have a significant value in the implementation of the disease control especially in Sudan. |
