“…In terms of the weed flora associated with quinoa crops, seed yield in conventional tillage systems was found to be 5-13% higher than that under minimum tillage, likely due to the lower weed density and biomass (Kakabouki et al, 2015). In addition, the density of perennial weeds, such as purple nutsedge (Cyperus rotundus L.), and the density of small-seeded weeds, such as redroot pigweed (Amaranthus retroflexus L.) and common purslane (Portulaca oleracea L.), were significantly lower under conventional tillage than under the minimum tillage system.…”

D.J. Bilalis, I. Roussis, I. Kakabouki, and A. Folina. 2019. Quinoa (Chenopodium quinoa Willd.) crop under Mediterranean conditions: a review. Cien. Inv. Agr. 46(2): 51-68.Quinoa is a pseudocereal crop that is well adapted to a wide range of climatic conditions and has significant potential for increased production as a new crop in the Mediterranean region and in other parts of the world, including northern Europe, North America, Asia, and Africa. Because of its exceptional nutritional properties, quinoa is highly appreciated among humans as well as in animal nutrition for feeding both ruminants and nonruminating animals. Data obtained from several studies conducted in Greece, Italy, and Turkey demonstrate the high nutritional and functional potential of quinoa. Nitrogen fertilization has a positive effect on the growth and grain yield of quinoa crops. The biomass has high crude protein and low fiber and is competitive with alfalfa. The assessment of quinoa saponin content is of great importance for the industry. The highest saponin content and yield have been found under organic cropping systems. Oat, bean, and duckweed plants have a great phytotoxic response, especially to the inflorescence tissues of quinoa, confirming the potential allelopathic activity of this promising crop. The major part of the root system is concentrated in the upper 0-30 cm of the soil, and the root length density and root mass density increase with increasing applied nitrogen. In conclusion, quinoa may be suggested as a new alternative crop for semiarid and arid Mediterranean conditions affected by multiple abiotic stress factors because of its stresstolerant characteristics, adaptability to several agro-ecological conditions, and nutritional and economic value.

“…Cardina et al (2002) reported that in moldboard plow plots the densities of Amaranthus retroflexus and Veronica arvensis were both lower compared to no-tillage plots. Kakabouki et al (2015) indicated that weed biomass and density in quinoa crop were influenced by the different fertilization and tillage treatments with tillage effects being species dependent. Similarly, total weed coverage and perennial coverage in reduced tillage treatments were two to three times greater compared with conventional treatments (Sans et al, 2011).…”

“…At the same time, soil N fertility was considered to have effects on weed seed mortality for some specific weed species, such as Abutilon theophrasti, Ambrosia trifida, and Eriochloa villosa (Davis, 2017). On the other hand, Kakabouki et al (2015) mentioned an increase in TABLE 2 | Indicative response of conservation and conventional tillage practices on weed abundance and diversity.…”

Weeds pose a major threat to world agriculture by reducing detrimentally crop yield and quality. However, at the same time, weeds are major interacting components of the agroecosystems. Abundance and diversity of weeds vary significantly among the several communities. In order to evaluate each community's structure and the interactions among them, several population indices are used as key tools. In parallel, various cultivation and land management strategies, such as tillage and fertilization, are commonly used in terms of integrated weed management. Estimating the response of weed species on those practices is crucial for both biodiversity maintenance and alternative weed control methods. Many experiments have confirmed the fundamental role of tillage intensity and nutrition supply in weed species' abundance and diversity. For instance, in some studies, the abundance of perennial weeds was doubled under reduced tillage intensity. In addition, higher values of Shannon-Weiner and Pielou indices were reported in the PK fertilization treatment compared to the control and NK fertilization treatments. The objective of this paper is to provide a brief overview of the key results of these experiments and summarize the part of the literature related to the effect of tillage systems and fertilization on weed species abundance and diversity. Such knowledge could contribute to the sound design and implementation of integrated weed management programs which in turn may lead to a decrease in the density of serious and noxious weeds and an increase in the overall balance of agroecosystems.

“…Furthermore, it was observed that Simpson index was dominant in cattle manure and compost treatments. Several studies reported the increase of weed emergence in manure because some weed seeds remain viable in the manure (Sary et al 2009;Monaco et al 2002, Bilalis et al 2012Kakabouki et al 2015). Even weed emergence may be attributed to the germination enhancement of weed seed already in the soil, some of seed come from weed grazed by cattle (Kakabouki et al 2015).…”

Nevertheless, rainfall and some other environmental factors, such as mean annual temperature may also affect the structural variability of the weed community (Tang et al 2014).…”

Weeds are among the most harmful factors limiting crop production in savannah zone of Africa. However, they are crucial for biodiversity and ecosystems sustainable management. A field experiment was conducted in savannah zone of Senegal to determine the effect of organic and mineral fertilization on weed flora in peanut crop. The experiment was laid out in randomize complete block design with four replicates and four treatments (Control, Cattle manure, Compost, and Mineral fertilizer). Our findings show that weed density was not significantly affected by the type of fertilization. However, dry matter of grasses and broadleaf weeds was significantly affected by the treatment respectively in forty and sixty days after treatment. The highest dry weight of grasses was observed in forty days after sowing in cattle manure treatment followed by inorganic fertilizer with respectively 23.7 and 15.2 g/m 2. In sixty days after sowing, the highest dry matter of broadleaf weeds was recorded in cattle manure treatment with 4.5 g/m 2. It was noticed that Digitaria horizontalis and Mesosphaerum suaveonlens were the dominant species in all treatment. The biodiversity indices were not significantly influenced by the type of fertilization but the highest values of Shannon-Webber and Simpson indices was recorded in cattle manure treatment. Moreover, the linear correlation between grain yield and diversity indices revealed that Shannon index is highly correlated with the peanut yield.
