“…Bosnic and Swanton (1997) reported that barnyardgrass at 39 plants m −2 reduced corn yield by 14% when they emerged at the 3‐leaf corn stage as compared with 4% at the 7‐leaf stage. In Michigan, Fausey et al (1997) reported that corn grain yields were reduced by up to 14% by 13 giant foxtail plants m −2 germinating 2 d after corn emergence.…”

sufficiently to survive the winter. Cover crop residue can modify the conditions under which weeds germinate Cover crops often reduce density and biomass of annual weeds in or regrow in the spring. Such effects could be due to no-till cropping systems. However, cover crops that over-winter also changes in soil temperature, increase in soil moisture, have the potential to reduce crop yield. Currently, there is an interest in annual medics (Medicago spp.) and other annual legumes that release of allelopathic chemicals, and physical impediwinter-kill for use as cover crops in midwestern grain cropping systems. ments to weed seedlings (Facelli and Pickett, 1991; Teas-A 2-yr study was conducted at East Lansing and the Kellogg Biological dale, 1996; Teasdale and Mohler, 1993).

“…Knake and Slife (1962) reported 25% yield loss caused by more than 150 giant foxtail plants m-1 row across 3 yr in Illinois. Giant foxtail at greater than 100 plants m-1 row resulted in 40% yield loss in Michigan (Fausey et al 1997). In contrast, Langton and Harvey (1994) reported that 168 giant foxtail plants m-1 row did not cause yield loss in an experiment in Wisconsin.…”

Variation in interference relationships have been shown for a number of crop-weed associations and may have an important effect on the implementation of decision support systems for weed management. Multiyear field experiments were conducted at eight locations to determine the stability of corn-foxtail interference relationships across years and locations. Two coefficients (IandA) of a rectangular hyperbola equation were estimated for each data set using nonlinear regression procedures. TheIandAcoefficients represent percent corn yield loss as foxtail density approaches zero and maximum percent corn yield loss, respectively. The coefficientIwas stable across years at two locations and varied across years at four locations. Maximum yield loss (A) varied between years at one location. Both coefficients varied among locations. Although 3 to 4 foxtail plants m−-1row was a conservative estimate of the single-year economic threshold (Tc) of foxtail density, variation inIandAresulted in a large variation inTc. Therefore, the utility of using common coefficient estimates to predict future crop yield loss from foxtail interference between years or among locations within a region is limited.

Maize - Production and Use

Maize is a widely grown cereal after rice and wheat and contributes almost 5% to the global dietary supply. In the Eastern Gangetic Plains (EGP) including India, Bangladesh, and Nepal, maize is an emerging cash crop, because of its high yield potentiality and also the favorable climatic conditions which allow maize production round the year. In Bangladesh, area and production of maize are escalating due to the increasing demand for poultry, livestock, and fish feed, and fodder for animals and starch industries in the region. Presently, more than 90% of maize is planted by manual dibbling following 5-6 intensive tillage, which increases the cost of cultivation. The conservation agricultural (CA)-based new agricultural practices could overcome those above challenges. CA is cost-effective and environmentally friendly; however, weeds are one of the key challenges in the system. The chapter described the uses of herbicides in different ways of combinations to make effective weed control in CA-based maize to achieve potential production and profits by reducing the intensive pressure of manual weeding. The efficient and right use of pre-plant/sowing, pre-and post-emergence herbicides and their combination may be the best way for effective control of weeds in maize production.
