Weekly in-season progress reports of the Ontario field crop landscape
Corn planting is 20-90% complete depending on the area of the province; provincially planting is estimated at 65%. Some of the early (i.e. April 5-15) planted corn had emerged and the cold temperatures of April 27, 28 & 29 froze the above ground tissue. However, to date, growing point and seed integrity remains high in […]
Freeze injury is a significant concern in the winter cereal crop with the very low temperatures of April 27/28/29. Leaf damage is significant in most fields, but it is head damage that is critical. Split stems in frost prone areas. Heads should be bright green to yellow. Discoloured or water soaked appearance of heads indicates […]
Cool and dry conditions have slowed grass development. Do not start grazing until the grass has the 3rd leaf emerged (a minimum of 7 to 10 cm) and then rotate quickly between paddocks. Management during the first round of rotational grazing can affect the productivity of the pasture for the rest of the summer; do […]
A few fields of soybeans were planted in the province last week. Field conditions were excellent. Little seeding progress is expected this week with cool and wet conditions. Weather permitting it’s expected that considerable acreage will be seeded in the first week of May. This would be ideal for maximum yield potential. When planting soybeans this early do […]
Nitrogen (N) dramatically increases the yield of grass stands, as well as forage protein levels. Optimum rates depend on the cost of N, anticipated value of the hay, thickness of stand, moisture conditions, and whether it is pasture or hay. Good grass stands with less than one-third legume, can generally benefit from at least 70 […]
Depending on the area, 10 to 60% of the corn crop has been planted. Provincially corn planting is estimated at 35%. Soil conditions remain dry and friable in most areas; the lack of soil moisture is an increasing concern and has forced deeper planting especially on light textured soils. Cold temperatures and rain/snow mix has […]
Co-Author: Scott Banks Winter cereals are moving forward slowly with the cool temperatures. Cold nights in low heat unit areas (-5oC) continued to stress the crop and show tip burn on leaves. A few more November acres have been targeted for replant with insufficient stand establishment to qualify for crop insurance. Manganese (Mn) deficiency is […]
There is nothing worse than having cattle to feed and then being caught off guard by low forage yields due to winter injury. If you have not already done so, walk alfalfa fields and dig some plants to assess for winterkill, heaving, frost damage and plant health. Watch for crown and root rots, brownish disclouration, […]
There is a significant increase in acres of new forage seedings. Many forage seedings are already in the ground. Ensure good seed-to-soil contact by preparing a firm seedbed. Forage inventories are exceptionally low for this time of year, with record high hay prices being reported. Frost Damaged Alfalfa: A considerable amount of alfalfa was damaged […]
Winter cereals responded immediately to warmer temperatures and showers over the weekend, regaining good green colour and growth. A few isolated acres in frost prone areas have been killed by frost (a first in my 27 years). Significant varietal differences in frost injury. Whether this will translate into yield differences remains to be seen. Advanced […]
Depending on the area, 5-30% of the corn crop has been planted. Soil conditions have been very good. Cool temperatures (especially at night) in the last week have slowed the emergence process. If drying trends continue growers are advised to be cautious with secondary tillage that is too aggressive (too deep, too many passes) and […]
A few “experimental” fields have been seeded. Although the long term Ontario data shows an average yield gain to early planting there are also increased risks. Over the last 3 years the yield loss associated with delayed planting has been 0.1 bu/ac/day after April 20th. The majority of soybeans should be planted in late April […]
Challenges and opportunities for the 2012 soybean crop Soybean acres continue to increase. Shorter crop rotations will mean soybean growers have to be vigilant in selecting disease resistant varieties, scouting their crop, and applying inputs when required to prevent crop losses resulting from short rotations. Soybean Cyst Nematode (SCN) can become a problem in short […]
Challenging planting conditions could affect crop emergence and early development. Additionally, a significant portion of the corn and soybean acreage was planted with limited opportunity for pre-emergence herbicide application. These factors will increase the importance of early crop scouting and staging to assess stands establishment and determine proper timing of post-emergence herbicide application. Stand Establishment […]
