“…Conversely, canola performs best during mild winters (Oplinger et al., 1989). In a 2021 national survey, winter canola had medium to high winter survivability at all locations below 39°N latitude (Secchi et al., 2021), which includes the Mid‐South. Heat stress during bloom resulting in yield losses (Morrison & Stewart, 2002) is more likely problematic for Mid‐South canola production.…”

Winter oilseeds are cool season Brassica crops currently being grown in the upper Midwest and North-West of the United States. They have the potential to function as dual crops when grown in rotation with corn, soybean, and small grains. They provide many of the benefits of typical cover crops over winter, with the added benefit of extra revenue to growers who sell the seeds for uses such as biofuel, industrial products, human consumption, or animal feed. This review gathers current agronomic and industrial use information about canola (Brassica napus L.), camelina [Camelina sativa (L.) Crantz], and pennycress (Thlaspi arvense L.). Currently, most research involving these crops is specific to the Midwest. This review also poses questions regarding how these crops could be adapted to grow in the Mid-South, with further research being necessary in several areas before promoting adoption in the region.

“…It has been noted that some B. napus cultivars can survive short-term temperatures as low as −19 ˚C, but only if adequate stand acclimation is achieved; however, cold hardiness varies among cultivars (Waalen et al, 2011). Secchi et al (2021) determined that the number of days between −10 and −15 ˚C, the number of days with temperatures moving above and below freezing, and the wind chill temperature were important factors in determining winter mortality in winter canola. They also concluded that areas between 35 and 40˚N latitude may have winter mortality issues.…”

Winter canola (Brassica napus L.) production has increased in the United States over the past several decades; however, there is little research in the southeastern United States on its agronomic production and growth characteristics under different nitrogen (N) fertilizer rates. The objectives of this study were to determine the effects of N rates on winter mortality, yield, oil and protein content, and seedpod shatter resistance across cultivars. Canola was grown in a randomized split complete block design with four replicates under five different N rates (0, 56, 112, 168, and 224 kg N ha−1) with four different cultivars (Hekip, Inspiration, and Edimax CL or Phoenix CL). Seed yield was very low for the 2017–2018 season, likely due to extreme cold conditions in winter and/or frost at flowering. There was high winter mortality during this period, but Edimax CL had significantly lower mortality (79.7%) than Inspiration (85.7%) and Hekip (83.9%). In the following year, more mild temperatures led to low mortality and greater yields, where rates of 112, 168, and 224 kg N ha−1 had the greatest yields (1,612–1,857 kg ha−1) with no significant differences according to cultivar. In 2018, shatter resistance was greatest for the rates of 112, 168, and 224 kg N ha−1 and was positively related to N rate. Across both years, Inspiration had greater shatter resistance. In 2019, the lowest N rate (0 kg N ha−1) and Phoenix CL had significantly greater oil contents (48.4 and 47.3%, respectively), whereas the highest N rate (224 kg N ha−1) with no particular cultivar had a significantly greater protein content (21.0%).

“…Significant changes in these variables can suppress or enhance the advantages of technological advances or improved management. Temperature and precipitation are the most studied variables regarding weather/climate and crop relationships (Kukal & Irmak, 2018; Leng & Hall, 2020; Ray et al., 2015; Secchi et al., 2021; Simmonds et al., 2013).…”

Abnormal ear development in corn: Does hybrid, environment, and seeding rate matter?

et al. 2023

Corn (Zea mays L.) yields have increased in the United States since the 1930s and in other parts of the world since the 1950s and 1960s because of improvements in agricultural management and genotypes. Despite these increases, production concerns still exist. In July 2016, abnormal ear development (multi-ears per node, barbell-ears, and short-husks) was reported in cornfields that extended from the Texas Panhandle to eastern Colorado and east through Kansas, Nebraska, Iowa, and Illinois. Surveys in Nebraska farmer fields revealed significant productivity losses due to the issues, but little was known about the underlying causes. A research study was conducted in four Nebraska fields during the 2018 and 2019 growing seasons. The research investigated the effects of hybrids, environments, seeding rates, and their interactions on abnormal ears. Eight hybrids, eight environments, and five seeding rates were studied. About 63,500 plants were individually assessed at or after the dent stage (R5). Grain yield ranged from 4.3 to 20.1 Mg ha −1 . In 2018, about 5% of ears were abnormal; in 2019, about 11%, if combined, about 8%. Higher-yielding hybrids were associated with lower percentages of abnormalities. Hybrids, environments, and seeding rates influenced the occurrence of abnormal ears. In most cases, abnormal ears had lower heights in the canopy, suggesting that primary ear loss may be a factor. The results reinforced the overriding hypothesis that ear abnormalities result from environmental, genetic, and management interactions. Depending on the environment, selecting certain hybrids with optimum seeding rates could help mitigate the occurrence of abnormal ears.
