Comparison of sesame and lentil susceptibility to soil residual effects of total, apirus, and atlantis

ABSTRACT - This research was conducted in order to study the sensitivity of sesame (Sesamum indicum L.) and lentil (Lens culinaris L.) to soil residue of three herbicides, including total, apirus, and atlantis under greenhouse conditions. The experimental design was a completely randomized design in a factorial arrangement with three replications. The stem and root length as well as stem and root dry weights were measured regarding both crop species. It was observed that the highest level of atlantis residue reduced the sesame stem length up to 91.61% compared to control. This herbicide decreased the sesame stem dry weight up to 89.93% compared to control plots, which was significantly higher than reduction caused by total and apirus. The maximum (76.67%) and minimum (53.13%) reductions were recorded in the lentil stem length compared to control plots by atlantis and total, respectively. Furthermore, the values of GR50 for sesame were significantly lower than those of lentil against the application of total, apirus, and atlantis, which were 0.5, 0.51, and 1.1 g ha-1, respectively. Generally, sesame showed a higher sensitivity than lentil versus the application of total, apirus and atlantis. Therefore, utilization of sesame could be more effective tool compared with lentil in the bioassay studies.
