Interference of sterile oat (Avena ludoviciana) and Mexican pricklepoppy (Argemone mexicana) in chickpea

Context Knowledge gaps exist for the interference of Avena ludoviciana and Argemone mexicana in chickpea grown eastern Australia.Aims This research aimed to examine effect different levels A. their potential cause yield loss chickpea.Methods Experiments were conducted a randomised complete block design with five weed infestation both weeds (none, low, medium, high, very high) three replications.Key results Infestations at 15 17plantsm−2 caused an 83 48% reduction yield, respectively, compared weed-free situations. Based on regression model, 50% occurred 10 mexicana, respectively. modified hyperbolic maximum seed production level 1plantm−2 was estimated 366 7800seedsm−2, At crop harvest, retention greater than 50 90%, respectively.Conclusions substantial yield. High suggests possibility manage these two through harvest control.Implications The information generated from this study could help strengthening integrated management chickpea.
