In Uganda, rice has grown to become an important food security crop and source of cash income for the majority of the rural farming communities across the country. Despite its importance, rice production has consistently remained low averaging 1.5 t/ha under farm conditions. The low production of rice is attributed to a number of production constraints. Therefore the objective of the survey was to ascertain the major production constraints in rice growing in the two sub-counties of Orum and Ogor, Otuke district. A diagnostic survey using semi- structured questionnaires was conducted in the two sub counties between July and August 2010 to gather information on the major production constraints from key informants, opinion leaders, farmers, technical and political leaderships. The findings showed that diseases were the major constraints in rice production accounting to 27% compared to other constraints. The other constraints included insect pests （23%）, weeds （21%）, drought （20%） and low prices （9%）. The major diseases encountered were rice blast （30%）, brown spot （23%）, rice yellow mottle virus （19%）, sheath rot （15%） and grain rot （13%）. Overall, diseases accounted for 79% of the yield reduction in rice. The implication of these findings therefore is that diseases and other constraints in rice production must be adequately identified for easy management to ensure sustainable rice production. More importantly, farmers should be sensitised on disease recognition, means of spread and control.展开更多
