Seedling emergence as influenced by aggregate size and bulk density
Producers in western Canada are becoming increasingly interested in conservation tillage. A thorough understanding of how seedlings interact with the soil surrounding them is required to develop criteria for designing ...
Rhizobium inoculant formulation and placement in lentil and chickpea in the semiarid Canadian prairies
Lentil and chickpea are the major pulse crops grown in western Canada, but little is known about the responses of these annual legumes to rhizobium inoculant formulation, placement, and their interaction to fertilizers ...
Nitrogen fertilization of canola and wheat grown on fallow fields
This is the second year of a three-year project to assess N fertilizer needs of canola and wheat grown on fallow fields. The project is being carried out at six sites (three in Saskatchewan and three in Alberta) utilizing ...
Effect of seeding date on yield and quality of winter wheat (cv. Norstar) grown on stubble and chemical fallow in south western Saskatchewan
Winter wheat (cv. Norstar) was seeded at one site (clay loam stubble) in 1984-85, and three sites (clay loam stubble and chemical fallow, sandy loam stubble, and heavy clay stubble) in 1985-86 and 1986-87. Conditions were ...
Where is nitrogen going in long-term cropping systems?
Fertilizer nitrogen use efficiency (NUE) is normally low, and has led to the idea that a large proportion of N applied as fertilizer is lost from the soil. However, N balances calculated for a long-term rotation study at ...
Why are tame hay yields declining in Saskatchewan?
Provincial agricultural production statistics show that grain crop yields have generally increased over the past 35 years while tame hay yields peaked in 1980 and have since been in decline. Weather data from 16 sites ...
