Common sunflower (Helianthus annuus) and shattercane (Sorghum bicolor) interference in corn

Abstract: Multiple weed species in the field combine to cause yield losses and can be described using one of several empirical models. Field studies were conducted to compare observed corn yield loss caused by common sunflower and shattercane populations with predicted yield losses modeled using a multiple species rectangular hyperbola model, an additive model, or the yield loss model in the decision support system, WeedSOFT, and to derive competitive indices for common sunflower and shattercane. Common sunflower and sh… Show more

“…Emex australis and E. spinosa also significantly differed in interference with wheat. These results are supported by Deines et al (2004), who studied the interference of Helianthus annus and Sorghum bicolor in corn. Multiple species caused 60% yield loss.…”

“…These decisions are based on estimates of weed population size, and the crop yield loss to be caused by that population and the most effective weed control practices to regain potential yield loss (Deines et al, 2004). Extensive herbicide use is one of the major tools for managing weed population and maintaining economical food supply in developed agriculture-based countries.…”

“…To avoid or compensate yield losses, estimation of economic weed population (density) and its management by an effective method are very important in crop production (Deines et al, 2004). In weed management, the importance of weed threshold level is in open sight, because it is very helpful for farmers that use herbicides (Portugal & Vidal, 2009).…”

“…Wild onion is a very harmful and noxious weed in chickpea, wheat, mustard, linseed and lentil in Pakistan and India (Nasir & Sultan, 2004) due to its high competitive ability, greater production of seeds and reproduction potential. It is found in almost 17 countries of the world (Holm et al, 1977). Although competitive effects of A. tenuifolius have been studied in wheat, lentil and mustard, no research has been conducted on its competitive effects on chickpea under rainfed chickpea-chickpea cropping system (Mishra et al, 2006).…”
