“…In addition, within agroecosystems, crop residues (e.g., straw mulch) can create a physical barrier and a shading microenvironment for weed suppression in IWM programs [ 4 ]. Before the adoption of reduced- or no-till systems, crop residues were normally burned or buried though deep ploughing in conventional tillage, whereas the widespread adoption of conservation agriculture systems globally has facilitated stubble retention in IWM programs [ 31 ]. Oat ( Avena sativa L.) is a major grain and forage crop, and its stubble (3000 kg ha -1 −8000 kg ha -1 ) is often left in the field after harvest, with oat straw mulch exhibiting a high weed suppression ability [ 32 ].…”

Chenopodium album L. is a troublesome annual species in various cropping systems, and a sound knowledge of the ecological response of C. album germination to environmental factors would suggest suitable management strategies for inhibiting its spread. Preliminary laboratory-based research was conducted to investigate germination and emergence requirements of C. album under various environmental conditions (e.g., photoperiods, constant temperature, salinity, moisture, soil pH, burial depth, and oat crop residue). Results showed C. album seeds were found to be photoblastic, with only 13% germination in darkness. The maximum germination (94%) of C. album occurred at an optimal temperature of 25°C, and the depressive effect of other temperatures on germination was more severe at lower rather than higher temperatures. Seed germination was suitably tolerant of salinity and osmotic potential, with germination observed at 200 mM NaCl (37.0%) and -0.8 MPa (20%), respectively. Germination was relatively uniform (88–92%) at pH levels ranging from 4 to 10. The maximum germination of C. album was observed on the soil surface, with no or rare emergence of seeds at a burial depth of 2 cm or under 7000 kg ha-1 oat straw cover, respectively. Information provided by this study will help to develop more sustainable and effective integrated weed management strategies for the control of C. album, including (i) a shallow-tillage procedures to bury weed seeds in conventional-tillage systems and (ii) oat residue retention or coverage on the soil surface in no-tillage systems.

“…SR (conservation crop plants) was more efficient than IR (conventional), in controlling weeds in first growing season. Zhang et al (2021) demonstrated that a cover crop was more effective in decreasing weed density. Also weed density was more affected by incorporated residues than weed emergence.…”

The weed suppressive potential of three cover crops: two forage hybrids of corn and sorghum and a local population of millet, used in conservation of agriculture was investigated. The allelopathic potential of cover crops was studied based on bio-assays. The effect of three tested crops were used on weed dynamics (weed density, Weed Control Efficiency (WCE). Two types of residues management (TRM) were followed: standing and incorporated residues (SR, IR).Forage residues showed an allelopathic effect on germination and seedlings growth of rye-grass. Sorghum significantly reduced weed density. Incorporated residues method was more effective than standing residues in reducing weed density. Millet residues was more efficient to control weeds whereas corn residues increased weed biomass. Weed Control Efficiency was also influenced by two types of residues management which showed a highly significant interaction with tested crops. Bangladesh J. Bot. 52(3): 845-852, 2023 (September)

“…Up until now, the research within the North China Plain has predominantly centered on investigating the effects of irrigation methods (Pei et al, 2017;Yang et al, 2022), crop residual managements (Zhang et al, 2021), tillage techniques (Liu, Lin, et al, 2023), and carbon footprint (Zhang, Guo, et al, 2023) on the crop yields, with relatively limited attention devoted to the realm of SQ. Consequently, it is anticipated that through a heightened focus on SQ exploration, comprehensive insights into the precise impacts of management strategies across various soil layers through long-term fixed-point experiments may emerge.…”

The North China Plain plays an important role in China's crop cultivation regions, with the wheat‐maize rotation serving as the predominant cropping system. Nonetheless, a dearth of research refers to the impact of tillage and fertilizer employment on soil quality (SQ) in this region. In this study, the primary objective centered on utilizing the soil quality index (SQI) derived from both minimum and total datasets (MDS, TDS) by the linear and nonlinear scoring criteria to assess SQ. The results indicated that there was a significant correlation between wheat‐maize yield and SQI, revealing a significant association between yield and key soil parameters such as bulk density, soil porosity, total phosphorus, alkali‐hydrolyzed nitrogen, available phosphorus and cation exchange capacity at 0–60 cm soil layer. The study identifies that substantially elevated SQI mean values were completely under T8 whose values were 0.980 (linear), 0.672 (nonlinear) under MDS and 0.908 (linear), 0.701 (nonlinear) under TDS at 20–40 cm. Importantly, the annual yields were the highest when the SQI values were the maximum. Furthermore, SQ levels within this locale demonstrate a moderate to highly favorable status, ultimately underscoring the area's propitious conditions for crop cultivation. This research provides indispensable theoretical guidance for agricultural practitioners and offers a foundational framework supporting enhanced yields in local grain crops.
