Biology and Ecology Top of page. Pigweed that emerges after a crop's minimum weed-free period may not reduce the crop's yield, but it should be pulled or cut before flowering to prevent formation of mature seeds. Once the crop is too large to cultivate by tractor, farmers often mow, cut, or pull weeds in alleys to maintain air circulation around the crop, facilitate harvest, and prevent weed propagation. The scientific name of Marijuana is Cannabis. Use slow-release sources of N and other crop nutrients, and avoid broadcast application of faster-release materials like blood meal and bone meal, which can give pigweed the jump on the crop. Polygonum cuspidatum goes by several other common names, including Japanese knotweed and fleece flower. 2003. Guo, P., and K. Al-Khatib. It is often used for slow-starting crops like carrot, beet, and parsnip. Effect of photoperiod on the phenological development of redroot pigweed (, Keeley, P. E., C. H. Carter, and R. J. Thullen.

Decline of weed seeds and seedling emergence over five years as affected by soil disturbances. Amaranthus palmeri is a species of edible flowering plant in the amaranth genus. Watch the crop closely; if a significant amount of pigweed grows with it, terminate the crop promptly when weed flower heads first appear. It is hardy to zone (UK) 4 and is frost tender. Amaranth: From the Greek word for “unfading,” Amaranth are grain-producing plants that have flowers and foliage in a range of colors from reds and purples to golds and greens. Amaranthus albus is a ANNUAL growing to 0.7 m (2ft 4in). Important pigweed species Although flushes of emergence commonly follow seedbed preparation or cultivation, increasing pigweed problems in agronomic crops have been attributed to widespread adoption of no-till and minimum-tillage, which leave recently-shed weed seeds at or near the soil surface (Sellers et al., 2003). Botanical Name of Spices, Common Name of Spices, Family Name of Spices, Part Used As Spice, List of Indian Spices, Names of Spices with Pictures, Hindi Names of Spices, Spices Names in Urdu In taller crops like corn, pigweeds respond to canopy shade by increasing stem growth and deploying leaves higher on the plant, thereby intercepting a larger fraction of available light (Massinga et al., 2003; McLachlan et al, 1993). The common name “Pigweed” is formed by “pig +weed”. However, rapid stem elongation allows pigweeds to escape shading in many cropping situations. Competitive summer cover crops such as buckwheat, sorghum–sudangrass, cowpea, and forage soybean are often used to suppress weeds between spring and fall vegetable crops. The name Portulaca is derived from the Latin ‘porto’ meaning ‘to carry’ and ‘lac’ meaning milk, due to the presence of milky latex in plant. An easy guide to growing PIGWEED WHS naaT i a n Me?

List of Scientific Names of Animals (Bot.) The final flush can also be killed by flame if grass weeds are few or absent. However, in studies conducted on organic (muck) soils in Florida, smooth pigweed and spiny amaranth were less responsive than lettuce to P levels, and a band application of P fertilizer improved the crop's ability to compete against these weeds (Santos et al., 1997; Shrefler et al., 1994). Rapid N mineralization from the all-legume cover crop residues apparently stimulated pigweed germination and growth. The “Cannabis” or “Marijuana” is one of the oldest psychoactive agent used by human race in the history.

However, in upstate New York, 2–4-inch fragments of Powell amaranth inflorescences lying on the soil surface were found to contain black seeds 3 weeks after the weeds were disked down at flowering (Charles Mohler, Cornell University, pers. It has several common names, including carelessweed, dioecious amaranth, Palmer's amaranth, Palmer amaranth, and Palmer's pigweed. Pigweeds typically begin to flower and shed pollen (anthesis) about six weeks after emergence (WAE), although flowers can occur as early as 3 WAE or as late as 9 WAE (Huang et al., 2000; Keeley, et al., 1987; Shrestha and Swanton, 2007).

Garden weeds listed botanically with common names. Although 5–14% of redroot pigweed and waterhemp seeds have survived 9–12 years burial at 8-inch depth in Nebraska (Burnside et al., 1996), others have reported that pigweed seeds are fairly short lived (3–4 years) in the soil in more humid regions such as Mississippi and Illinois (Buhler and Hartzler, 2001; Egley and Williams, 1990; Steckel et al., 2007). (Available online at: Tisler, A. M. 1990. Although stringent weed control for six years can reduce the pigweed seed bank by 99%, relaxing weed control allows seed numbers to recover to near original levels within three years (Schweizer and Zimdahl, 1984).

[1913 Webster] … The Collaborative International Dictionary of … Comparative growth of six, Shrefler, J. W., J. Interference of Palmer amaranth in corn. Because pigweeds produce seed so prolifically, it is critical to minimize the annual seed rain onto the soil. 2007. Pigweed seeds have multiple dormancy mechanisms, so that seeds produced in a given season germinate at different times over the next several years, thereby enhancing the weed's long-term persistence (Egley, 1986). Along with Chloe and Bentley, other botanical names for babies in the US Top 1000 include Aspen, Briar, Daisy, Nash, Oliver, Rowan, Sylvie, and Zaria.
