Improving Greenfeed Success When Seeding Late

Annual crops are a late season seeding option when used for livestock feed or ground cover. They can be grazed within four to six weeks of planting thus providing rest and recovery for your pastures or harvested as greenfeed or silage for winter feed. Generally planting prior to July 1 will ensure most crops will reach the optimum harvest stage for greenfeed or silage production. However in the event that you are not able to seed as early as desired, find in the attached article some considerations that will help you improve yields and quality.

There are also multiple articles on MAFRD’s website on greenfeed and annual crops to increase feeding flexibility:

Options for Managing Drowned Out Spots

The following is from an article by Tom Peters, Extension Sugarbeet Agronomist with NDSU & U of MN, published in  North Dakota State University CROP & PEST REPORT July 10, 2014 Issue, with a Manitoba perspective by Pam de Rocquigny, Manitoba Agriculture Provincial Cereal Crops Specialist

If you take a drive across Manitoba, you’ll notice the impact of excessive moisture on crops.  Symptoms of excess moisture can include crop yellowing, hastened crop development such as premature bolting in canola, stunted growth, and in extreme cases crop death in drowned out areas.

What options do producers have to manage these drowned out spots?  Producers should continue to actively manage these areas of fields since they are a perfect environment for weeds to grow without crop competition and potentially will produce tremendous numbers of weed seeds. Left unattended, these spots could dramatically impact weed management strategies for future crops in future years.

So what options does a producer have? Some questions to consider are whether you can reach these spots with equipment such as a rotary mower or a sprayer and what will effectively control the weeds?

  • Mowing is a good option, but in all likelihood, affected areas in fields will need to be mowed on 10 to 14 day intervals to prevent weed seed production.
  • Spray the drowned-out areas of the fields as if you were managing a crop if you are still spraying the field for weeds (if the drowned out spots have dried enough for a sprayer pass of course). If you are spraying only the affected areas, be sure to consider the crop around the drowned out spots to prevent damage to the surviving crop.  And keep in mind any potential crop rotation restrictions to next year’s cropping plans with the product you are using.
  • A third possibility is to plant the drowned-out areas of the field to a cover crop such as a cereal, once again if the area is dry enough to allow a seeder to pass. Cover crops will use excess water in soils and will compete with weeds for light and thus may limit germination and emergence of weeds.

Preparing Unseeded Acres for Winter Wheat

Producers that have been unable to seed an annual crop this spring due to excess moisture conditions may want to consider preparing a portion of their land for winter wheat seeding this fall.

The key to successful winter wheat production is winter survival. The most successful management factor to help ensure winter survival is seeding into standing stubble that will catch and hold snow.  This is something that was evident the spring of 2014 where generally winter wheat seeded into good standing stubble survived the winter better than those fields that had poor stubble and therefore poor snow catch.

The following article was originally written by John Heard, Crop Nutrition Specialist with MAFRD in 2005, then updated in 2011 and now again in 2014.
