Old Rotation Study – Swift Current, Saskatchewan
The “Old Rotation” experiment was initiated in 1966 at the Agriculture and Agri-Food Canada Research Centre at Swift Current, Saskatchewan. The overall objectives were to evaluate the influence of rotation length, fallow substitute crops, and nitrogen (N) and phosphorus (P) fertilizers on crop yields, grain protein, N and P uptake, moisture conservation, nutrient use efficiency, incidence of di...
متن کاملNew Rotation Study – Swift Current, Saskatchewan
The “New Rotation” experiment was initiated in 1987 at Swift Current, Saskatchewan. The objectives were to evaluate, under conservation tillage management, the influence of crop and rotation type on crop productivity and grain quality, incidence of plant diseases and weed populations, a suite of soil and environmental parameters, economic performance and energy use efficiencies. The study provi...
متن کاملModification of a Self - Propelled Rotary Mower for Wheat Forage Harvest
Many field experiments require the collection of forage yields in addition to grain yield (small grains). ln smal! plot research, mechanized grain harvest is common. However, forage harvest is often accomplished by hand which is time consuming and labor intensive. Sample heterogeneity increases when forage harvest is obtained by hand. The objectives of this study were to construct a mechanized ...
