Duck production on croplands under zero-tillage management : final report / Wayne F. Cowan.

TextPublication details: Winnipeg, MB : 1978. Ducks Unlimited Canada,Description: 51 p. : ill. , maps ; 28 cmSubject(s): Online resources: Abstract: Duck nest densities and success rates on croplands under zero-tillage were studied in 1977 and 1978 to test the theory that duck production could be increased over that on farms under conventional tillage management. The improvement would be realized, theoretically, by the retention of a relatively unaltered nesting substrate (standing stubble)throughout the nesting season, reductions in nest destruction by farm implements, and reduced predation due to dispersal of nest sites. Three paired study plots varied in size from a quarter-section to a section of land, each composed of a zero-tillage farm (experimental) and a conventional farm (control). Nests in fields and native cover were located by flushing setting hens by means of truck and rope drags,beat-outs, and dogs, and by accompanying farming operations in fields.All nests were protected from destruction by implements during seeding activities.
