“…It has been found that plant residue management can regulate the diversity and composition of the weed population by introducing qualitative and quantitative changes [138,139]. Residual CCs in the form of dead mulch change soil properties, which can impact weed control by affecting the survival, dormancy, predation, and long-term viability of weed seeds [140,141]. As dead mulch, legume CCs shade the surface of the soil and thus capture solar radiation.…”

Legume Cover Crops as One of the Elements of Strategic Weed Management and Soil Quality Improvement. A Review

The benefits of conservation practices increased the interest of farmers in the cultivation of cover crops (CCs). This review aims to present and analyze the state of the art on the cultivation of legume CCs, including their importance in protecting crops against weeds, as well as their effects on organic matter and nitrogen content in the soil, physical and biological properties of the soil, and its erosion. The multi-purpose character of legume CCs is visible in their positive effect on reducing weed infestation, but also on the soil: reducing its compaction and erosion, improving its structural and hydraulic properties, increasing the content of organic matter and activity of soil microorganisms, or increasing its nitrogen content due to symbiotic N2 fixing. This review demonstrates that a wider use of legume CCs in organic farming is needed. The benefits of legume CCs for successive crops in these cultivation conditions, both in terms of inhibiting weed populations and improving fertility and soil properties, also need to be identified. Further research is also needed to determine the potential impact of legume CCs on the improvement of the quality of degraded soils, or those with less favorable physicochemical properties.

“…The highest suppression of weeds was recorded in the wheat field as a result of sunflower residue incorporation because of the release of allelochemicals as well as the reduction of light penetration (Reberg-Horton et al, 2005;Alsaadawi et al, 2007). Crop residues may change the frequency and distribution of weeds, and they suppress weed emergence and weed growth (Essien et al, 2009;Khaliq et al, 2015). Previously, Zaji and Majd (2011) showed that the fresh and dry weights of different weeds biota viz.…”

“…They provide nitrogen through release into the rhizosphere of the tested crop plant. Through the application of residues as a biological weed management strategy, it immobilizes nitrogen, which may decrease the immediate supply of nitrogen (Khaliq et al, 2015). However, at later stages of crop growth, the availability of nitrogen was enhanced through mineralization, proving that the prolonged supply of nitrogen is a continuous source of nutrition for the test crop as well as the next crops.…”

“…Allelopathic crops have strong potential for the development of cultivars that are highly weed-suppressive (Weston and Duke, 2003). Incorporation of allelopathic crop residues suppressed weeds through physical hindrance or by posing chemical (allelopathy) effects and improved soil health (Khaliq et al, 2015). Crop residues are good sources of nutrients and the primary source of organic material added to soil.…”

Sunflower Residue Incorporation Suppresses Weeds, Enhances Soil Properties and Seed Yield of Spring-Planted Mung Bean

Continuous and excessive use of herbicides to control various weed biotypes is posing severe threats to soil and human health. Nevertheless, the strategy of using allelopathic crop residues and water extracts for weed control seems to be a sustainable and friendly option to reduce dependence on synthetic herbicides. In addition to controlling weeds, residues of allelopathic crops positively affected soil health. A two-year field study was carried out to examine the impact of sunflower residues on soil properties, weed dynamics and productivity of mung bean. The study was comprised of five treatments viz., control, sunflower water extracts at 10 and 20 L ha-1, and sunflower residues incorporation at 4 and 6 ton ha-1. Results indicated that application of sunflower water extracts reduced weed density by 5-26% and weed dry weight by 9-31%, while sunflower residue incorporation caused 44-57% reduction in weed density and 58-70% reduction in weed dry weight compared with the control. At mung bean harvest, total nitrogen and organic matter in soil were increased by 86% and 74%, respectively, with the incorporation of sunflower residues at 6 ton ha-1 as compared with the control. In case of soil enzymes, alkaline phosphatase and dehydrogenase were recorded at 186 mg NP g-1 soil h-1 and 38 mg TPF g-1 soil h-1, respectively, when sunflower residue was incorporated at 6 ton ha-1. In conclusion, sunflower residue incorporation at 6 ton ha-1 improved soil health, suppressed weeds and resulted in better seed yield (36%) and profitability (339 $ ha-1) of spring-planted mung bean.

“…The main reason might be the severe recourse competition inflicted by weed during the reproductive phase of the crop (Khaliq et al, 2015). Riaz et al (2006) and Khan et al (2007) have also observed less spike length when weeds were interfering with wheat crop.…”

Crop Growth and Yield Losses in Wheat Due to Little Seed Canary Grass Infestation Differ with Weed Densities and Changes in Environment

-Understanding the weed interference with different sowing times of crop is inevitable for forecasting yield losses by weed infestation and designing sustainable weed management systems. A field experiment was carried out to evaluate the effects of sowing dates (20 th November, 10 th December) and various little seed canary grass (LCG) infestation levels (10, 20, 30 and 40 plant m -2 ) on growth and yield of wheat under semiarid conditions. Plots with two natural infestations of weeds including LCG (Unweeded control; UWC) and excluding LCG (UWC-LCG) were maintained for comparing its interference in pure stands with designated densities. A season-long weed-free (WFC) treatment was also run. All the weeds/ LCG infestation levels starting from 10 LCG plants m and UWC were comparable, however, these losses were much greater than UWC LCG. In crux, delay in sowing of wheat not only reduced the crop growth and yield but also enhanced the LCG/weed interference. Furthermore, greater competitive ability of LCG particularly for latesown wheat suggests that it should be controlled in order to provide healthy environment for crop plants.Keywords: interference, little seed canary grass, sowing time, weeds, wheat yield losses.
