| Abstract: The objective of this work was to evaluate the adaptability of different lettuce (Lactuca sativa) cultivars grown in no-tillage on straw of ruzi grass (Urochloa ruziziensis), as well as its effects on soil temperature and weed control, in successive cultivations in the summer. The treatments were carried out in a randomized complete block design, with four replicates, in a split-plot arrangement (2x4), in which soil management (no-tillage on ruzi grass and convention tillage) was the main plot, and the different crisphead lettuce cultivars (Amanda, Solaris, Vanda, and Vera), the subplots. No difference was observed between cultivars for soil management. No-tillage reduced the soil temperature by up to 3.7°C and weed density by 3.7 times, in... |

| Abstract Background: Allelopathic plants like safflower (Carthamus tinctorius) can be considered as natural herbicides for weeds management in field. But there is not enough research on safflower genotypes allelopathy potential. Objective: So in this study, allelopathic effect of the four safflower genotypes on weeds (Amaranthussp., Hordeum spontaneum), crops (Sesamum indicum, Triticum aestivum) and on autotoxicity of Carthamus tinctorius was evaluated in bioassay using sandwich method. The results can be used in the management of weeds in safflower fields and also in the rotation with other crops. Methods: Two genotypes with high allelopathic potential and two genotypes with low allelopathic potential were selected from forty genotypes of safflower.... |

| ABSTRACT: This study aimed to further explore that if coumarin and lavender’s extract, similar to greenhouse conditions, are phytotoxic towards some plant species under agronomic conditions. Before planting of maize, coumarin at 0, 250, 500, 1,000, 2,000, and 4,000 g h-1 and lavender’s aqueous extract at 0, 1,000, 2,000, 4,000, 8,000, and 16,000 mL h-1 were applied and incorporated into soil at a 3-5 cm depth. The density and biomass of weeds was significantly reduced by applying both compounds. The inhibition ability was also rate-dependent. Although the density and biomass of maize was also decreased at high rates, this crop showed higher tolerant to both compounds that all weeds. |

| Abstract. Pedicularis kansuensis is a dominating poisonous weed, and it might have allelopathic effects on other native grasses in alpine meadows. An experiment was conducted to examine a range of concentrations of aqueous whole plant extracts (25, 12.5, 2.5, 1.25, 0.25 and 0.0 g/L) of P. kansuensis, prepared at the flowering stage on seed germination and seedling growth of two native grasses (Poa pratensis and Elymus nutans). High concentrations of aqueous extracts of P. kansuensis inhibited seed germination and seedling growth of P. pratensis (p< 0.05). Most aqueous extracts of P. kansuensis had a stimulatory (p< 0.05) effect on E. nutans. Our results suggest that the allelopathic ecology of P. kansuensis on other native grasses needs further... |
