Wheat residue management options for no-till corn

Abstract: Opoku, G. and Vyn, T. J. 1997. Wheat residue management options for no-till corn. Can. J. Plant Sci. 77: 207-213. Corn (Zea mays L.) yield reduction following winter wheat (Triticum aestivum L.) in no-till systems prompted a study on the effects of tillage and residue management systems on corn growth and seedbed conditions. Four methods for managing wheat residue (all residue removed, straw baled after harvest, straw left on the soil surface, straw left on the soil surface plus application of 50 kg ha -1 N in… Show more

“…Similar results of the percentage of straw removed were found by other authors [32][33][34]. In particular, Bergonzoli et al [34] also found similar effects on machine performance by varying the chaff collection device.…”

“…Swan et al (1996) and Opoku and Vyn (1997) showed similar findings. Differences between the two treatments were more pronounced during the drought in spring of 2001, when soil moisture differences were also greater.…”

“…Since the stem apex (growth point) is below the soil surface up to the V5 vegetative stage (Ritchie et al 1997), which makes young maize plants very susceptible to soil environmental modifications as affected by cover crops. Inadequate soil moisture, low soil temperature, poor maize seed contact with the soil and even adverse allelochemical influences of cover crop residues on young maize plants are the most quoted impediments to early maize growth after cover crops (Campbell et al 1984, Opoku andVyn 1997). In order to determine the benefits of cover crop practices in Indiana, USA, previously conducted research (Ryan 2000) showed that winter wheat might be a promising choice for the cover crop in a 2-year maize-soybean crop rotation, because it is well adapted to local environmental conditions and it can produce beneficial soil physical properties.…”

“…The smaller pieces are more difficult to pick up with the baler. Under Ontario growing conditions, Opoku and Vyn (1997) estimated straw removal with baling at between 50 and 57% from studies conducted over two growing seasons.…”
