“…In general, early cover crop planting with a late termination date resulted in greater cover crop biomass accumulation compared to a late cover crop planting with an early termination date. These results are similar to previous studies evaluating biomass with different cover crop management strategies ( Mirsky et al 2017 , Webster et al 2016 , Sciarresi et al 2020 , Rosa et al 2021a ). We hypothesized that management strategies that result in greater cover crop biomass would support more arthropod prey resulting in greater arthropod activity.…”

“…Utilizing legumes as part of a mixture in a cover crop can modify starter nitrogen rates and water management in a grass cover crop to grass cash crop rotation could be a viable strategy to reduce the potential for negative impacts on yield ( Clark et al 1995 , 1997 , 2007a , b ). Sciarresi et al (2020) found that in a cover crop-soybean system, the selection of a soybean maturity group could be an option to increase the cover crop growth period for greater biomass accumulation without impacting soybean yield. However, cash crop yield is not the only important profitability parameter that should be evaluated in a cropping system.…”

“…The main plots consisted of four cover crop planting dates and a no-cover crop plot as a check with a split-plot treatment of two cover crop termination dates. Each cover crop planting date was planted based on the harvest date for a range of soybean maturity groups (0.6, 1.8, 2.5, 2.9, and 3.4) that were planted into the main plot in the spring of each year, following the methods described by Scirresi et al (2020) for Mead, NE. Table 1 shows the cover crop planting dates for each growing season.…”

Relative to fallow-cash crop rotations, the addition of a cover crop can contribute to greater plant diversity and has the potential to conserve predatory arthropods. The transition of arthropods from a cover crop to a subsequent cash crop depends on several factors, such as cover crop biomass production and weather conditions. Information about the effect of cover crop planting and termination dates on arthropods in a subsequent corn system is limited. A two-year field study was conducted in Nebraska in 2018/2019 and 2019/2020 to evaluate the impact of cover crop planting and termination dates as a source for arthropods in the subsequent corn. A total of 38,074 and 50,626 arthropods were collected in the first and second year, respectively. In both years, adding a grass cover crop increased predatory arthropods but reduced yield in follow corn crop. Of the arthropods collected, Carabidae and Araneae had greater activity with cover crop biomass increments, whereas Collembola and Acari activity only increased in treatments with little or no cover crop biomass. Insect pest pressure was not significant in any treatment for either year. A cover crop planted in mid- or late-September and terminated at corn planting was identified as the best management strategy to maximize cover crop biomass, increase predator activity, and modify predator-prey dynamics. The results of this study provide growers with a cover crop management strategy to maximize cover crop biomass, beneficial arthropod activity, and potentially minimize insect pest problems; however, corn Zea Mays (L.) grain yield was reduced as cover crop biomass increased.

“…Egli (1993) reported that the yield potential of soybean cultivars is not associated with the growth period indicating that early-maturity cultivars with a shorter growth period can produce similar yield to late-season cultivars. Sciarresi et al (2020) reported that earlymaturity cultivars provide a wider window (up to 11 d) for fall operations such as the establishment of fall-seeded cover crops, application of fall burndown herbicides for controlling troublesome winter annual weeds, and tillage. In the United States, there is increased interest in including cover crops in corn (Zea mays L.)-soybean rotations for reducing soil erosion and nutrient runoff or leaching and improving nutrient cycling and soil moisture capacity .…”

Soybean [Glycine max (L.) Moench.] yield is determined by interactions amongst soybean cultivars' genetic potential, agronomic practices, and environmental conditions. Despite the high adoption of herbicide-resistant soybean cultivars across Nebraska and the United States, the comparative yield potential of non-herbicideresistant ("conventional") cultivars in not well understood. A field experiment was conducted at five locations across Nebraska in 2017 and 2018 to determine the effect of row spacing (15 and 30 in), cultivar maturity group (2.2-2.4 and 3.2), and herbicide resistance traits (conventional, glyphosate-resistant, and glyphosate-and dicambaresistant) on soybean yield. Narrow row spacing increased the soybean yield in three of five research locations. The soybean yield in Auburn in 2017, Albion in 2018, and Cedar Bluffs in 2018 increased by 11.9, 10.2, and 11.4% in narrow compared with wide rows, respectively. Cultivar maturity group and herbicide resistance traits did not affect soybean yield under weed-free experimental conditions. These results suggest that growers could benefit from earlier maturity groups, as they provide an opportunity for earlier harvest, allowing growers to better spread their field activities in the fall. The grain yield potential was similar between conventional and transgenic herbicide-resistant cultivars. Therefore, conventional soybean cultivars can be a viable option when adequate weed management can be achieved through conventional weed management strategies.

“…Earlier reports for this region showed constant maximum yields until a threshold date when yields start to decline (Vitantonio-Mazzini et al, 2021), and our results for MG V matched with the previous ones. In some production systems where sowing date is delayed adapting cultivar choices to lower maturity group has a less detrimental effect on yield (Egli & Bruening, 2000;Sciarresi et al, 2020). In contrast, Grassini et al (2015) found that shortening the crop duration by choosing a shorter maturity group in later sowing dates amplified yield penalties.…”

Sowing date affects soybean biological nitrogen fixation

et al. 2022

In many temperate soybean [Glycine max (L.) Merr.] production systems sowing date expands for several months. Early sowing dates commonly show maximum yields, but their consequences for crop N uptake and biological nitrogen fixation (BNF) are unknown. Our objective was to evaluate the role of sowing date, a major management variable defining soybean yield, on BNF. We hypothesized BNF is maximum at intermediate sowings because BNF is limited by low soil temperatures at early sowing dates and by high soil nitrate concentrations at later sowings. Four genotypes (maturity groups [MGs] IV and V) were tested over a 16‐wk sowing date period, and a N fertilizer treatment at sowing was added in all sowing date by genotype combinations (0 and 100 kg N ha–1). The N fertilization treatment helped to test sowing date effects independently of soil N availability. Seed yield and total N uptake were affected by sowing date and genotype, but not by the N treatment. Both seed yield and total N uptake followed similar quadratic responses, but MG V genotypes maximized yield and N uptake at the earliest sowing while MG IV cultivars maximized both traits at intermediate sowings. However, delaying sowing date always decreased the proportion of total aboveground N that came from BNF (average decline 0.22% d–1). Nitrogen fertilization reduced BNF by 15% across sowing dates and genotypes, with no yield effect. The linear decline in BNF with delayed sowing dates, instead of an optimum response, supports the concept that soil nitrates are the main driver of soybean BNF in this production system.
