Crop rotation and diversification (CRD) are crucial strategies in sustainable agriculture, offering multiple benefits to both farmers the environment. By alternating crops or introducing diverse plant species, CRD practices improve soil fertility, reduce pest populations, enhance nutrient availability. For example, legume-based rotations increase nitrogen levels through biological fixation, reducing need for synthetic fertilizers. Moreover, these promote more efficient water use, reliance on fertilizers minimizing risk of pests diseases. This review synthesizes findings from recent research role enhancing agriculture resilience, highlighting potential contributions towards climate change mitigation adaptation. Specific crop systems, such as cereal–legume temperate regions intercropping maize with beans tropical environments, reviewed provide a comprehensive understanding their applicability different agroecological contexts. The also addresses challenges related implementing practices, market demand knowledge transfer, suggests solutions encourage broader adoption. Lastly, environmental benefits, including carbon sequestration reduced greenhouse gas emissions, discussed, building resilient agricultural systems. Collectively, this paper emphasizes importance methods provides key insights researchers effectively integrate into farming

Growth Competition between Rice (Oryza sativa) and Barnyardgrass (Echinochloa oryzicola) under Varying Mono-/Mixed Cropping Patterns and Air Temperatures

Agronomy, Journal Year: 2024, Volume and Issue: 14(3), P. 574 - 574

Increase in the concentration of atmospheric greenhouse gases significantly contributes to global warming, representing a substantial challenge for crop production. The study was conducted determine growth competition between rice (Oryza sativa) and barnyardgrass (Echinochloa oryzicola) under (i) different cropping patterns (ii) elevated air temperatures phytotrons field condition, at two plant densities (4 16 plants per pot). Rice were planted with varying (rice: mixture proportions); 100:0, 75:25, 50:50, 25:75 0:100. Air maintained as follows: Ambient–A (Control), A +0.8 °C, +1.9 °C +3.4 °C. Plant attributes such height, number effective tillers, shoot dry weight grain yield recorded this rice/barnyardgrass proportions order 100:0 > 75:25 50:50 25:75. highest (37.7 g/pot) monoculture (100:0 rice/barnyardgrass) ambient temperature, whereas lowest (0.3 proportion increase temperature had significant impact on growth, tillers both followed ambient. However, higher negatively affected resulted decrease yield. Barnyardgrass showed characteristics when grown alongside compared monoculture. This indicates that highly competitive interspecific an intraspecific competition. In contrast, grew better than barnyardgrass.

Deciphering the Genetic Basis of Allelopathy in japonica Rice Cultivated in Temperate Regions Using a Genome-Wide Association Study

Rice, Journal Year: 2024, Volume and Issue: 17(1)

Published: March 26, 2024

Allelopathy has been considered as a natural method of weed control. Despite the nature allelochemical compounds studied, little is known about genetic basis underlying allelopathy. However, it that rice exhibits diverse allelopathic potentials across varieties, and breeding for plants exhibiting potential conferring an advantage against weeds in paddy fields would be highly desirable. Knowledge gene factors identification genomic regions responsible allelopathy facilitate programs. Taking existing diversity rice, particularly temperate japonica we conducted comprehensive investigation into determinants contribute to Employing Genome-Wide Association Study, identified four Quantitative Trait Loci, with most promising loci situated on chromosome 2 5. Subsequent inspection genes located within these QTLs revealed associated biosynthesis secondary metabolites such Phenylalanine Ammonia Lyase (PAL), key enzyme synthesis phenolic compounds, two coding R2R3-type MYB transcription factors. The provides useful tool further exploration targeted strategies.

Inductive Effect of Exogenous Abscisic Acid on the Weed-Suppressive Activity of Allelopathic and Non-Allelopathic Rice Accessions at the Root Level

Agronomy, Journal Year: 2024, Volume and Issue: 14(10), P. 2297 - 2297

Published: Oct. 6, 2024

Rice allelopathy is a natural method of weed control that regarded as an eco-friendly practice in agroecology. The root growth allelopathic rice at the seedling stage plays important role its control. Our study characterizes plant hormone promotes growth, abscisic acid (ABA), to explore induction allelopathy. Increasing morphology traits (root length, tip number, and biomass) using different concentrations exogenous ABA resulted increased inhibitory ratios against barnyard grass (Echinochloa crus-galli), both hydroponic experiment pot test. In particular, relative proportion induced total non-allelopathic Lemont (Le) was higher than PI31277 (PI). content phenolic acid, which allelochemical rice, previously reported, significantly elevated exudates PI LE. gene expression levels OsPAL, OsC4H, OsCOL related synthesis were also up-regulated, with regulatory fold PI. OsKSL4 CYP75B4 involved biosynthesis momilactone B tricin. Moreover, low mainly positively regulate OsIAA11, AUX/IAA transcription factor gene, Le. These findings suggest application could enhance weed-suppressive activity cultivars through regulating allelochemicals secreted by roots, providing option for improvement chemical induction.
