2016-2017 Winter Canola Performance Trials

Production Season

The 2016-2017 production season was full of mixed growing conditions, therefore crop performance winter canola across Oklahoma was mixed. This was the first year since the historic drought that canola growers throughout the state were faced with several canola production challenges. Throughout the season, the crop was rated as good to poor, depending on time of year, planting date, management and location.


During planting, growers that planted early were able to get the crop emerged and begin early growth very quickly following planting. This was a result of adequate soil moisture and timely rainfall events, paired with mild temperatures during the end of September into early October. Growers that planted during the last week to 10 days of September or early October were met with several challenging conditions that limited the number of acres that were successfully established during this period. Dry conditions in portions of the state limited growers’ ability to plant in a timely manner, while other areas of the state had adequate moisture at planting and received heavy rainfall events following planting. The latter resulted in several fields being drowned out or severely crusted, which limited overall emergence or resulted in very uneven emergence across the field. Many of these growers had to replant in mid- to late October, which is later than OSU recommends.


After planting, optimum growing conditions were present from October through late November to early December. This resulted in excessive vegetative growth for the early planted canola, with many reports of two- to four-foot canola and some canola attempting to bolt prior to the first major freeze event. For those that planted late or had to replant into later October, this provided adequate time for the canola crop to mature, as well as set enough leaves and roots to aid in over-winter survival. The first major freeze event for most of Oklahoma occurred in late November or early December. While most of the state did receive adequate chilling days prior to this first freeze, many of these days were interspersed with very warm conditions, thereby not allowing the canola plant to adequately harden-off or prepare for winter. A heavy freeze event occurred in mid-December in which several locations across Oklahoma reached temperatures below 0 F, with several locations reported -20 F. Additionally, in many areas, soil moisture was limited at the times of these freeze events, which increased the level the damage typically resulting in higher winterkill events than if adequate soil moisture had been present. These heavy freeze events caused a high amount of winterkill issues across the state, with many producers reporting more than 50 percent winterkill. This was especially true on fields planted in early September and had excessive vegetative growth. Winterkill was not seen as prominently in fields that had been replanted or were planted during the mid- to late October period.


Spring green-up occurred much earlier than normal with many locations around the state starting to see regrowth in late January to early February. This resulted in many producers not being able to make timely fertilizer or herbicide applications prior to the bolting stage. Due to the winter freezes and the early spring, many plants started bolting with little to no additional leaf growth. As most photosynthesis still occurs in green leaves during the bolting and early flowering stages, many of these plants appeared stressed during early reproductive stages. This resulted in many plants only reaching 2 to 3 feet tall prior to flowering. With little leaf material prior to flowering, weed control became an issue in many locations with warm conditions paired with timely rainfall events.


Temperatures cooled during the months of March and April and above-average pod filling conditions existed. During this time, the crop appeared to improve with increased number of lateral branches producing very large racemes and pods. While the crop reached reproduction earlier than normal, the crop matured at or near the normal timeframe. Growers experienced near perfect swathing conditions with good drying conditions at and near swathing due to the increased number of lateral pods. However, as swathing continued across the region, high temperatures and high winds lead to rapid drying and resulted in swathed canola reaching full dry-down in as little as three to five days. This potentially contributed to some pods having shrunken or smaller seeds than expected. At harvest, yields varied greatly. Several growers reported much lower yields than expected and in previous years.


In addition to environmental conditions possibly decreasing the yield potential, higher than average pest pressure potentially decrease yields. High lepidoptera pressure occurred throughout the fall. Most producers had increased pressure from armyworm in the early part of the fall, with increased diamondback moth larva during late fall and early winter. Due to weather and application cost, many producers were not able to adequately control these pests, which caused significant damage. Pest pressure continued throughout the spring. In late winter and early spring, lepidoptera pressure continued, mostly as diamondback moth larva and armyworm. If left untreated, pest pressure was high enough to terminate the crop in many areas. For many growers, insecticide treatments proved ineffective. It is unsure if this was a misapplication, poor conditions at application or resistance issues. As the canola progressed further into early flowering and early pod development, green peach aphids and cabbage aphids increased pressure through much of the state. While these initially started as isolated incidences, more wide-spread pressure resulted.


Overall, the year was mixed for canola producers throughout the state, with many growers having higher or substantially lower yields than previous seasons. For many growers throughout the state, the cost of growing canola increased with the elevated pest pressure they were faced with throughout the fall and spring. On a brighter side, many producers throughout the region noted the wheat following last season’s canola was noticeable higher yielding. This has increased the interest in canola throughout the state, and several growers are planning on continuing with the crop for the foreseeable future.

 

Interpreting the data

Details of establishment and management of each test are noted above the production tables. Least significant differences (LSD) for yield are listed at the bottom of the summary tables at the beginning of the document. Differences between cultivars are significantly different only if they are equal to or greater than the LSD value. If a given cultivar out-yields another cultivar by as much or more than the LSD value, then we are 95 percent sure the yield differences are due to actual differences, with only 5 percent probability that the differences are due to chance alone. For example, if cultivar X yielded 500 pounds per acre more than cultivar Y, then it is significantly difference only if the LSD value is 500 or less. If the LSD value is 501 pounds per acre or greater than we are less confident that cultivar X outperformed cultivar Y under the conditions of the test. Additionally, in the summary tables, the highest yielding cultivar is bolded and all cultivars that are not significantly different than the highest yielding cultivar are highlighted.


The results of these tests should be representative of what would occur throughout the state, but are more indicative of the environmental conditions and management practices similar to those under the testing conditions. This is due to the amount of influence that soil type, winter conditions, soil moisture, diseases and insects can play on yield.

 

Methods

All test locations contained both conventional and glyphosate-resistant cultivars. Plots were 5 feet wide by 20 feet long and seeded at the rate of 3 pounds per acre. All conventionally tilled plots were planted at 7.5-inch spacing, indifferent of tillage practices under the trial. Soil sample results are indicated on each table. All pest management practices were carried out in accordance with Oklahoma State University Cooperative Extension Service recommendations. Entire plots were either swathed and harvested or directly harvested (indicated on each table) at maturity.
