“…Different seeding rates can impact disease development, yield, and net return of a crop [ 40 , 41 , 42 , 57 , 58 , 59 , 60 , 61 ]. However, there is limited published data on the effects of different seeding rates on SDS development.…”

Three soybean field trials were conducted in Indiana to evaluate the integration of seed treatment, cultivar selection, and seeding rate on sudden death syndrome (SDS) root rot, pathogen load in the root, foliar symptoms, yield, and net return. Two soybean cultivars, one moderately resistant and one susceptible to SDS, were planted at three seeding rates (272,277 seeds/ha, 346,535 seeds/ha, and 420,792 seeds/ha). Fluopyram and pydiflumetofen seed treatments were applied to both cultivars, and the cultivars were then compared with a control. Low foliar SDS disease pressure was observed in our study. Seed treatment with either fluopyram or pydiflumetofen and the use of a moderately resistant cultivar decreased Fusarium virguliforme DNA concentration in the root relative to the control and the use of a susceptible cultivar. Fluopyram significantly reduced visual root rot severity by 8.8% and increased yield by 105 kg/ha relative to the control but was not different from pydiflumetofen. However, pydiflumetofen performed the same as the control with respect to root rot severity and yield. Findings from this study support the use of a seed treatment to protect roots from infection and the use of a moderately resistant cultivar planted at a seeding rate of 346,535 seeds/ha to protect yield and maximize net returns when a field has low foliar SDS pressure.

“…The comparative net economic return (CNER) of each planting date and seeding rate combination was used to evaluate economic gain or loss, compared with a base treatment similar to Rod et al. (2021). In this study, the base treatment was the normal planting date window (May 11 to 31) and a seeding rate of 370,600 seeds ha −1 .…”

Timely soybean [Glycine max (L.) Merr.] planting is ideal for maximizing grain yield. However, weather conditions often limit farmers’ ability to plant timely. The objectives of this study were to (a) measure the effect of soybean planting date and seeding rate on grain yield, (b) identify the agronomic optimum soybean seeding rate (AOSR) (the seeding rate where soybean yield is maximized), and (c) compare the net economic return of the base treatment (10 May to 31 May planting date and 370,000 seeds ha−1 seeding rate) to the other treatment combinations. The experiment was conducted in 2020 and 2021 in Ohio at the Western (WARS) and Northwest (NWARS) Agricultural Research Station with a split‐plot randomized complete block design with four replications. The whole plot factor was four planting dates ranging from 25 April through 1 July, and the sub‐plot factor was five seeding rates ranging from 123,500 to 618,000 seeds ha−1. When water was not limiting, soybean planted in April and May yielded 8 to 26% more than soybean planted late‐June. In general, planting in May resulted in a lower AOSR (247,000 to 303,000 seeds ha−1) compared to planting in June where AOSR ranged from 430,000 to 618,000 seeds ha−1. Comparative net economic return was the lowest (from $‐237 ha−1 to $‐938 ha−1) when soybean was planted after mid‐June at 123,500 seeds ha−1. These findings can help farmers improve soybean grain yield by adjusting their seeding rate based on planting date to maximize profitability.This article is protected by copyright.

“…Partial budget analyses consistent with Kay et al ( 2020) and Rod et al (2021) were used to determine the net economic return of each of the six management treatments for each planting timing in 2018 and 2019. Significant differences among the partial budgets were determined using the "t-test: two-sample assuming unequal variances" function in Excel 2013 (Microsoft).…”

Double-crop soybean [Glycine max (L.) Merr.] production in Kentucky involves planting soybean after soft red winter wheat (Triticum aestivum L.) harvest during June and July. Double-crop soybean yields are lower than full-season soybean yield planted earlier in the spring. This research aimed to determine the effect of seeding rate, seed treatment, and applying foliar fungicide and insecticide at the R3 growth stage at two planting timings on double-crop soybean seed yield, yield components, and seed quality. Field trials were established in Princeton, KY, in 2017, 2018, and 2019 after wheat harvest. Planting double-crop soybean early, after wheat was harvested at 20 to 22% grain moisture, resulted in increased seed yield, seeds ft -2 , and protein concentration compared with double-crop soybean planted later. A seeding rate of 225,000 seeds acre -1 resulted in increased seed yield, seeds ft -2 , and seed protein concentration compared with 150,000 seeds acre -1 . A seed treatment including fungicides and an insecticide did not impact seed yield, yield components, or seed protein or oil concentration compared with no seed treatment. Applying a prophylactic foliar fungicide and insecticide treatment at the R3 growth stage increased seed yield and seed mass compared with an economic threshold application. In addition, the most intensive management (225,000 seeds acre -1 , seed treatment, and prophylactic fungicide and insecticide) yielded ∼25% more than the base treatment and had more seeds ft -2 . The results are the first to indicate the potential for intensive management practices to increase double-crop soybean productivity in Kentucky.
