ABSTRACT.- Cover crops constitute an interesting option for cultural weed control. Expansion of herbicide resistant weeds in Uruguay, has been associated with an increase use of pre-emergent herbicides for their control. Crops residues could decrease their effectiveness. The objective of these work was to evaluate the effect of Avena strigosa straw and moment and amount of rain, in Amaranthus spp. control effectiveness by flumioxazin and sulfentrazone. Two experiments were carried out for each herbicide in pots, in a greenhouse. The design was in randomized complete blocks, with five repetitions and factorial arrangement of treatments. In experiments I, factors were: I) amount of A. strigosa straw (0 and 6 t ha-1); and II) amount of rainfall (20 and 80 mm), for each herbicide. In experiments II, factors were: I) amount of A. strigosa straw (0 and 6 t ha-1); II) amount of rainfall (20, 60 mm); and III) Days between application and rainfall occurrence (1, 7 and 14). Weed emergencies were quantified at days 8, 22 and 39 after rainfall (DAR). Results were independently analyzed using a model with gaussian distribution. Sulfentrazone effectiveness in Amaranthus spp. control was not affected by studied factors. In the case of flumioxazin, straw effect was consistently detected. Amounts of 6 t ha-1 of oat straw reduced Amaranthus spp. control effectiveness of the herbicide. © 2022 Informa UK Limited, trading as Taylor & Francis Group |

Rotatinuous stocking (RN) management is based on animal ingestive behaviour responses, where optimal preand post-grazing sward heights are defined to increase nutrient intake per unit of grazing time. We hypothesized that the optimal sward structure and consequently, a high herbage nutritive value in RN treatment results in a
greater faecal nitrogen (N) excretion by sheep and consequently, a greater faecal greenhouse gas (GHG) emissions compared with the traditional rotational stocking (RT) management, which is based on a maximum herbage accumulation and harvest. Therefore, the aim of this study was to evaluate the effect of two grazing
management strategies (RN and RT) on the amount of dry matter (DM) faecal excretion, faecal N excretion and faecal GHG (CH4 and N2O) emissions from growing sheep grazing Italian ryegrass pastures. In order to evaluate faecal production and N excretion per animal and per ha, a first experiment (1) was carried out: RT - pre and post-grazing sward heights of 25 and 5 cm, respectively and, RN - pre and post-grazing sward heights of 18 and 11 cm, respectively. A second experiment (2) was carried out to measure the CH4 and N2O fluxes from faeces, using the static chamber method. Daily DM faecal and N excretion per animal were higher (P<0.001) in RN compared with RT treatment. However, when considered daily DM faecal and N excretion per ha, results were lower (P<0.001) for the RN than the RT treatment. CH4 and N2O emissions from faeces were higher (P<0.001) in RN compared with RT treatment, both per animal and per hectare. In conclusion, our study showed that the RN grazing management, based on animal behaviour, resulted in a higher daily N excretion per animal and higher CH4 and N2O emissions from faeces of sheep grazing Italian ryegrass pastures. This study contributes to improve GHG national inventories for the subtropical Brazilian climatic conditions, where estimations from CH4 and N2O emissions factors for faeces from growing sheep grazing Italian ryegrass are markedly lower than the values reported by IPCC Default Tier 1.
