Recently, returning rice straw to soil has become a common problem in wheat production because it causes decreased seedling emergence. Allelopathy is an important factor affecting seed germination. However, the effects of extracts on germination and growth remain unclear. Wheat seeds seedlings were treated with 30 g L−1 leaf (L1), 60 (L2), stem (S1), (S2) sterile water (CK) study allelopathic growth. The α-amylase antioxidant enzyme activities seeds; agronomic traits, photosynthetic indicators, nutrient contents seedlings; phenolic acids determined. Common allelochemicals, including 4-hydroxybenzoic acid, hydrocinnamic trans-cinnamic vanillic benzoic protocatechualdehyde, caffeic syringic sinapic salicylic detected extracts.

Green agriculture faced challenges due to the shortage of efficient cadmium (Cd)-resistant plant growth-promoting bacteria (CdR-PGPB) and their low survival rate activity during application. In this study, a diverse range CdR-PGPB were isolated from rhizosphere soil Desmodium elegans, especially those with high phosphate-solubilizing capabilities (272.87-450.45 mg L

Cadmium (Cd) contamination is a major concern due to its toxicity and bioaccumulation in crops. The study researched the impact of rape (Brassica campestris) cultivation influence straw management on Cd accumulation rice (Oryza sativa L.) under rape-rice rotation system. Field experiments were set moderately Cd-contaminated farmlands, with treatments including removal (NR), return (RR), single cropping (SR). In contrast SR, NR effectively reduced 6.67-19.59% soil available 37.18-39.10% grains during 3 years. Compared RR, SR significantly decreased 17.17-27.78% concentrations 33.30-53.84% grain accumulation. Soil physical chemical properties influenced by return, further affecting mobility. This underscores that can be an effective tactic for reducing improve environment. research provides critical insights into sustainable agricultural practices soils, offering practical solutions mitigating risk rice, while highlighting importance crop rotations.
