This book was released on 2015 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is comprised of two studies on the effects of soybean ( Glycine max (L.) Merr.) planting date (PD) and maturity group (MG) selection on producer expected returns. Having to replant soybean after early-season planting because of poor stand establishment is costly for producers. Replanting costs have increased in the last ten years as seed and other input costs for soybean have increased. Using five years of field trial results from two locations in Arkansas, the yield response to early and late season plant population density has been estimated to determine yield and future revenue potential for the purpose of determining whether or not replanting makes economic sense for a producer. Economically derived soybean replanting thresholds, defined as the number of plants at two or four weeks after planting for the initial planting below which replanting makes economic sense, were established for both locations. Sensitivity analyses on soybean price, seed cost, and producer replanting costs were performed to determine their relative importance on replanting thresholds. Deciding to replant earlier than four weeks after planting was suggested as the yield potential of earlier replanted soybean is higher. The replanting threshold counts, however, also need to be adjusted. In the second study, producer return variance or production risk associated with growing soybean of different maturity and at varying times during the planting season was analyzed. An efficient frontier where returns are maximized at varying levels of risk was calculated for a set of nine locations across six states using three years of data from field experiments. Because a producer can freely select what MG of soybean to plant and when to plant, risk return tradeoffs were studied for planting portfolios featuring soybeans from MG III to VI and PD ranging from as early as the beginning of April in some locations to mid-July. The median level of risk between minimal portfolio risk and the risk level of the return-maximizing MG and PD combination was solved for and expected return and risk was compared between the median-risk portfolio and the profit-maximizing portfolio. This comparison provided insight about the relative cost of risk reduction for the nine different locations. Water consumption, price seasonality, and seed oil and protein concentration were considered in the development of return estimates. Because producer planting risk preferences vary, a spreadsheet tool that can solve for efficient MG and PD planting portfolios is envisioned that will allow the parameters of the optimization to be customizable for the producer.

Book Synopsis Identifying Optimal Management Decisions Based on Soybean Planting Date by : Thomas Bernard Siler
Download or read book Identifying Optimal Management Decisions Based on Soybean Planting Date written by Thomas Bernard Siler and published by . This book was released on 2020 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practice of early-season soybean [Glycine Max (L.) Merr.] planting has been increasing in the northern US. However, a wide range of planting dates (PDs) are still implemented due to poor soil conditions, inclement weather, equipment restrictions, crop rotation, and operation size. Information regarding how soybean management decisions should be adjusted based on PD is lacking in Michigan and other northern US regions. This research was conducted to identify how optimal soybean seeding rate (SR), seed treatment (ST) use, and variety maturity group (MG) selection is determined by PD. Field experiments were conducted at two locations in Michigan during the 2018 and 2019 growing season. In the first experiment, soybean was planted at five SRs, between 123,553 and 518,921 seeds ha−1, with or without a ST, on four PDs (late-April to late-June). In the second experiment, six soybean MGs, between 1.0 and 3.5, were planted on four PDs (late-April to late-June). The use of a ST did not improve yield or net returns in this study. When soybean was planted before mid-May, seed yield and net returns were maximized by planting a late MG (≥ 3.0) at a SR between 187,660 and 201,451 seeds ha−1. The optimal SR between the mid-May and early-June PDs was between 220,301 and 265,305 seeds ha−1 and MG selection had less influence on seed yield compared to earlier PDs. When planting was delayed to late-June, using an early MG (≤ 2.5) resulted in the optimal yield and the optimal SR was > 330,000. Results from this study show that soybean yield, quality, and net returns can be improved by adjusting management practices based on PD.
Book Synopsis Corn and Soybean Replant Decisions by : William John Wiebold
Download or read book Corn and Soybean Replant Decisions written by William John Wiebold and published by . This book was released on 1999 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deciding whether or not to replant a sparse stand is one of the more difficult decisions a corn or soybean grower will face. The difficulty of this decision stems from the difficulty of predicting how stand density will be affected by the combination of planting date and changing environmental conditions. This publication will help readers make corn and soybean replant decisions.
