Description: Irrigation ditch maintenance studies conducted by the Research Stations at Swift Current and Regina in co-operation with the Saskatchewan Department of Agriculture and Prairie Farm Rehabilitation Act indicate certain advantages of establishing low-growing grasses in ditches that are intermittently wet and dry during the irrigation season. Grasses such as stream bank wheatgrass, Russian wild rye grass, creeping red fescue, and sheep fescue controlled weed growth without impeding water flow. Since the complete cross section of the ditch is seeded, there is no need to treat the banks separately as with sterilants for which only the inside of the ditch below the waterline is treated. Seeding ditches to grasses rather than treating with sterilants overcomes the problems of pollution and potential damage to the crop when using sterilants (Korven 1975). Seeding ditches to grasses is the lowest cost method of irrigation ditch maintenance. Assuming a relatively high seeding cost of $25 per acre (1.6 km of ditch 2.5 m wide) and a stand life of 5 yr, the annual cost would be $5 per acre. This compares to a cost of $25 for burning, $50 for mowing, and $60-$70 for chemical treatments (Korven 1975). The ditches in the study were seeded by hand, which is not practical on a field scale. To gain the advantages of seeding ditches to low-growing grasses it was necessary to develop a grass seeder for irrigation ditches. This paper described the design and performance of the seeder for irrigation ditches.
