“…Rapid soybean growth early in the season as indicated by taller plants is common in the presence of weeds (7) or non‐coated RI soybean (16) when light is reduced. However, all RI plants were shorter than FS soybean at harvest ( visual observation ), which was consistent with other researchers (4,8,9,17). Height of 5143 NC was 1 to 5 inches greater than 5143 ITC for FS and RI soybean, while C4444 SK was slightly taller than non‐treated C4444 in RI soybean at Novelty in 2003, FS soybean at Novelty in 2004, and RI soybean at Albany in 2004.…”

“…Soybean are seeded into standing wheat before harvest which allows the beans a longer growing season. Researchers have evaluated RI soybean in the southern United States (12,17), Kansas (4), Missouri (13), Illinois (3,8,9), and Nebraska (11). In the Upper Midwestern United States, researchers evaluated RI to allow consistent DC production to move farther north.…”

Soybean seeded [Glycine max (L.) Merr.] early into standing wheat (Triticum aestivum L.) using relay intercropping (RI) and seed‐coat technology may reduce mechanical damage and soybean interference to wheat. Field research at Novelty from 2003 to 2005 and Albany in 2004 evaluated effects of seed coat technology on wheat and soybean response, and gross profits of RI soybean using seed coat technology compared with selected full season (FS) wheat or soybean and double crop (DC) wheat‐soybean. Wheat grain yield in the absence of soybean was 10 bu/acre greater in narrow (7.5‐inch) than wide (15‐inch) rows. Relay intercropped Intellicoat (ITC) treated 5143 soybean delayed germination and increased 15‐inch wheat grain yields 8 bu/acre compared to non‐coated (NC) 5143. At Novelty, RI 5143 ITC yield was similar in all three years and 7 bu/acre greater at Albany than 5143 NC. In 2005, dry conditions in mid‐ to late June reduced RI stands and yields compared to DC soybean at Novelty. Double‐cropped 5143 NC soybean had greater gross profits than RI 5143 ITC when wheat and soybean prices were high. However, RI 5143 ITC gross profits were greater when soybean prices were high and wheat prices were low. The RI system using ITC maintained soybean yields and did not reduce wheat yields due to mechanical damage or soybean interference compared to non‐coated or fungicide‐only coating.

“…In the present study, relay‐cropped soybean yields were on average 58 to 83% of that for the full‐season monocrop control and were greater than those for double‐cropped soybean. Although relay‐cropped soybean was planted near the same time as the monocrop soybean, the lower yield in the relay treatment was likely due to the competition of camelina for light, nutrients, and soil moisture during early vegetative growth of soybean, which has been demonstrated by others for soybean interseeded with wheat (Wallace et al, 1992). When averaged over both years of the study, relay soybean out yielded the double‐crop soybean by 33 to 70%.…”

Dual Cropping Winter Camelina with Soybean in the Northern Corn Belt

2014

Sustainably balancing biofuel crop production with food, feed, and ber on agricultural lands will require developing new cropping strategies. Double-and/or relay-cropping winter camelina (Camelina sativa L.) with soybean [Glycine max (L.) Merr.] may be a means to produce an energy and food crop on the same land in a single year. A study was conducted between 2009 and 2011 in west central Minnesota to evaluate yields, seed quality, economics, and within-eld energy balance of winter camelinasoybean double-and relay-cropping systems compared with a conventional monocropped full-season soybean. Systems included methods to hasten camelina harvest (e.g., swathing and desiccating) to promote early soybean growth. Camelina seed yields were una ected by cropping system and ranged from 1.1 to 1.3 Mg ha -1 . Relay-cropped soybean yields were greater than doublecropped soybean and were 58 to 83% of that for the monocropped control. Seed oil and protein content of double-and relaycropped soybean were comparable to their monocropped counterpart and combined seed oil yield for the dual crop systems was as much as 50% greater. Net economic returns for the relay-crop treatments were competitive with that of the full-season soybean. Moreover, net energy of the relay-crop treatments was generally as high as the sole soybean crop, but energy e ciency (outputs/ inputs) was less due to greater inputs. Results indicate that dual cropping of winter camelina with soybean is agronomically viable for the upper Midwest and might be an attractive system to growers seeking a "cash" cover crop.

“…soybean) into an earlier-planted crop (e.g. wheat) before the first crop is harvested is often termed a relay planting or relay intercropping system (Wallace et al, 1992). Monocropped plots were tilled the preceding fall in the same way as the double-cropped plots.…”

“…as a consequence, may be a viable management option for double-cropping in northeastern Mississippi (Wallace et al, 1992). A second common type of interaction, between cropping system and soybean row spacing, occurred six times, mid-season or later in 1982 and 1983 and early-season in 1984.…”

Cropping system influences on extractable water for mono- and double-cropped soybean

For rain-fed agriculture in the southeastern United States, efficient soil water use when doublecropping is essential. Water use by soybean [Glycine max (L.) Men.] following winter wheat (Triticum aestivum L.) is, however, poorly documented. Winter wheat may deplete soil water, thus limiting subsequent soybean yield. Cropping system variables, such as soybean planting date and row spacing, may also affect water use. Therefore, a 4-year field experiment in northeastern Mississippi was conducted on Leeper ( Vertic Haplaquept) and Catalpa (Fluvaquentic Hapludoll) silty clays. The objectives were to (1) determine the influence of soybean planting date, cropping system (monocropped versus double-cropped), and row spacing on extractable water ( similar to available water) for soybean, and (2) identify a production system to improve the use of extractable water over a growing season. In mid-to late-May ( the first soybean planting date), "Centennial" soybean in 38-or 76-cm rows was planted either between rows of standing wheat or in bare (monocropped) plots. After the wheat was harvested and the straw chopped, soybean was planted into bare soil or planted no-till into wheat stubble in mid-June for the second planting and in early July for the third. Soil water content was measured with a neutron probe from soybean emergence to maturity. Differences between each water content profile and a dry profile ( constructed using the lowest recorded water content at each depth) were regarded as extractable water. Neither soybean planting date nor cropping system, as a main effect, exerted much influence on extractable water for soybean. As interacting factors later in the season, however, they were important. Plots with soybean in 38-rather than 76-cm rows contained more extractable water throughout the 1982 and 1983 seasons, and yielded over 9% more seed. Canopies closed about 20 days sooner with narrow rows than with wide rows. These full canopies protected and shaded the soil surface, probably reducing crusting and decreasing water losses by evaporation. We concluded that double-cropped soybean in 38-cm rows planted either into standing wheat in late May or into wheat stubble not later than mid-June utilized extractable water efficiently in silty clay soils in northeastern Mississippi.
