2013年4月26日 · Have alfalfa field that was sprayed out last fall. It will be ready to seed before other fields. If I put wheat on it, then canola will have to go on canola stubble(would only be 2nd canola in 12 years)

2014年1月11日 · I've been considering using Canola as a cover for Alfalfa too. I've heard that alfalfa seedlings (non RR varieties) are tolerant to glyphosate. Would it be safe to seed RR canola into a dirty field and underseed with Alfalfa, spray twice.

Flax and canola are the preferred companion crops. Seed them in a separate operation, prior to and at right angles to the alfalfa seeding. This method minimizes the competition between the alfalfa and the nurse crop. Another method is to exclude the nurse crop from every fourth or fifth run of your seeder, drilling the alfalfa using only these ...

2014年6月6日 · Their particular setup involves seeding alfalfa with canola, using a triple shoot on the seed drill to seed two rows of canola between every row of alfalfa. Alfalfa has a small seed like canola, and therefore seeding depth is shallow, about one-half to one-quarter inch deep. Alfalfa is seeded in 36 inch rows.

Winter canola (Brassica napus) is used as a break crop in the primarily cereal grain rotations of the Pacific Northwest (PNW). Research over the last 40 years has largely been focused on grain production. However, renewed interest in using canola …

The study started in 2001 when all fields were seeded to canola to assess the spatial variability of yield and provide information required to delineate boundaries. The crop rotations including alfalfa/grass were established in May 2002 with an experimental design based on landform and field analysis. The study was designed with four 16.2 ha

2017年3月25日 · Where alfalfa seed producers can increase their leafcutter population over a season, canola seed pollinators will lose 40 to 50 per cent of the leafcutter population each summer due to the cool, humid microclimate produced by centre pivot irrigation.

2019年10月1日 · Fig. 3 compares the reflectance values of canola (3a), wheat and barley (3b), alfalfa (3c) and newly cultivated fields (3d) show distinctive spectral signatures at different times of crop growth in the blue, green, red and NIR bands.

Canola prefers soils with adequate infiltration and aeration. It is considered moderately tolerant of salt and sodium, tolerating salinity up to 5 to 6 mmho/cm (millimho per centimeter) before yields are reduced, similar to small grains. Canola performs well between pH 5.5 and 8.5 (1).

2019年12月1日 · Potato rotated with alfalfa had the highest energy use efficiency indicators. Longer 3 to 4-yr potato rotations with canola, wheat, or alfalfa are recommended. Crop rotations can be used to optimize energy use efficiency (EUE) by preserving or enhancing optimal fertility and chemical use and reducing greenhouse gas (GHG) emissions.
