“…Protein content was not affected by weeds or weed control methods in soybean (Abusteit, 1993;Chhokar et al, 1995) and wheat (Troccoli et al, 1997). Kayan and Adak (2006) did not demonstrate any significant effect of weed control methods on protein content in chickpea, and Mason and Madin (1996) mentioned that the effects of weeds on grain protein in wheat appeared to be complex and depended on the competition between crop and weeds for N and water at the end of the season. In these experiments with quinoa, there was a significant negative effect from weeds on protein content.…”

Weeds, with their negative influence on both yield and quality, constitute a major problem in the organic production of quinoa, a potential new seed crop for protein feed and human consumption in Europe. To attain effective weed control, mechanical weeding strategies, such as weed harrowing and inter-row hoeing, were studied. Weed harrowing operates over the entire plot with flexible tines, affecting both crop and weeds, whereas inter-row hoeing is performed between the rows, aiming only at the weeds. The study showed that both hoeing and harrowing reduced the quinoa density in one out of two years, whereas there was no effect on quinoa density in the other year. Yield was increased by both methods, but hoeing increased yield more than harrowing due to better weed control. Regression analysis showed that crop yield was related to weed dry matter and showed no indications of higher crop damage associated with weed harrowing. Protein content was low when weeds were not treated, and increased significantly when weeds were controlled. As a conclusion, inter-row hoeing was more efficient than weed harrowing with respect to weed control; however, weed harrowing should be optimized in future trials in narrow row spacing systems, and the results indicate that weed harrowing can be used as a supplement to inter-row hoeing.

“…Growth type and lifetime vary among weed species, so weed management program must be commensurate with the biological traits of weeds in the elds to achieve effective weed control (Kayan and Adak, 2006). On the other hand, in a weed community assemblage not all weed species are detrimental to crop yield and even some weeds species may have bene ts.…”

To evaluate the impacts of weed communities on chickpea yield (Cicer arietinum L.), an on-farm survey was conducted with a sampling from 85 dryland chickpea fields in a rural district, western Iran. The results showed that chickpea yield tended to decrease with increasing weed density and canopy cover as indicated by a polynomial response. Increasing weed density from 0 to 50 plant m-2 reduced the chickpea yield by 36.73% at the four to seven-leaf stage of chickpea. In addition, increases canopy cover from 0 to 55% caused chickpea yield loses by 41.70 g m-2 at the early podding stage of chickpea. Weed diversity and evenness had a positive effect on chickpea yield. Wild safflower (Carthamus oxyacantha M. Bieb.) and chicory (Cichorium intybus L.) were the most predominant weeds with a significant negative correlation with chickpea yield, weed evenness and diversity. Some weeds, such as licorice (Glycyrrhiza glabra L.) had a negative correlation with chicory and wild safflower and a positive correlation with weed diversity and evenness. In addition, there was a positive relationship between density and canopy cover of licorice and chickpea yield, weed diversity and evenness.
