A summary of placement and fall versus spring application of nitrogen fertilizers
In 52 field experiments since 1973-74, the yield of barley grain without N averaged 1570 kg/ha, but the yield was increased by fall and spring application of incorporated urea (56 kg N/ha) to 2540 and 3470 kg/ha, respectively. ...
Fire and iron: tools for disease management?
Large volumes of crop residue are often managed using tillage or burning. This study examined the effect of these practices on diseases of barley [leaf spots, Pyrenophora teres Drechsler and Cochliobolus sativus (Ito & ...
Management for optimum yield of open pollinated and hybrid canola
Newer open pollinated (O.P.) and hybrid canola varieties provide higher yield potential but the management strategies necessary to achieve optimum yield are not well understood. To better understand the levels of inputs ...
Potential for wind erosion in alternative cropping systems
The potential for wind erosion in agricultural soils is a function of the distribution of aggregates at the surface, soil structure and moisture, and crop residue. These properties were measured in a cropping systems study ...
Early supplies of available nitrogen to the seed-row as affected by fertilizer placement
A field experiment was conducted at Star City, (legal location SW6-45-16-W2); Saskatchewan, Canada from May to June 2000, to measure N and P supply rates from fertilizer band to canola seed row. Ion exchange resin membrane ...
