Última Effect of Amaranthus quitensis on parsley for dehydration yield Agriscientia (Córdoba) Puricelli,E.; Faccini,D.; Constantino,A.; Torres,P.. Weeds are a severe problem in many horticultural crops but information about weed competition on parsley (Petroselinum crispus (Mill.) Nym) yield is lacking. The objectives of this study were to determine the critical period for Amaranthus quitensis Kunth control in parsley and to quantify the influence of A. quitensis density on parsley yield. The critical period was variable between years and weed densities and ranged between 3 and 44 days in duration. In both years, A. quitensis densities of more than 30 plants/m² can account for up to 70 % of yield loss. The results indicate that A. quitensis can significantly reduce parsley yields even at low densities if the weed is not controlled in the appropriate period.

ABSTRACT: The aim of this research was to determine weed interference periods in sugarcane cultivated under the system of pre-sprouted seedlings, taking into account the impact on the final plant stand, and bud yield and stalk yield. In the field, this study used a randomized block design with 14 treatments and four replications. The treatments consisted of periods of control and weed coexistence with the sugarcane crop (cultivar IACSP95-5000): 30, 60, 90, 120, 150, 180, 210 and 240 days after planting. A phytosociological survey was carried out in the experimental area, and the species Merremia aegyptia, Urochloa decumbens and Nicandra physaloides were found to be predominant. At the end of 240 days, regression analysis was performed according to...
