| Using compounds such as salicylic acid as a plant growth regulator that can help plants against environmental stress is one of the most important and innovative strategies in agricultural science. Also, today, the planting of cover plants in order to reduce the use of herbicides has received a lot of attention. Therefore, cover plants are one of the effective tools in non-chemical management of weeds in sustainable agriculture. Sesame with the scientific name Sesamum indicum from the Pedaliaceae family is one of the oldest oil seeds that mankind has known and used. Therefore, the purpose of this research was to investigate the effect of foliar spraying of sugar alcohols and salicylic acid and types of living mulch on the quantitative and qualitative yield of sesame. Based on this, a factorial field research was carried out in the form of a basic design of randomized complete blocks with three replications in the year 1400 in Sosangerd. In this experiment, the main factor of foliar spraying of anti-stress substances with four levels (sorbitol (concentration 6%), mannitol (concentration 6%) and salicylic acid (concentration 0.08 mM) and non-use (control) was considered as the first factor. And the secondary factor of cover plants included: cowpea, mung bean, purslane and no cover plant (control). The results showed that the effect of foliar spraying and cover plants and their interaction on morphological traits, yield and yield components at the level of 1% significance ¬Dar. The highest amount of investigated traits was observed in the conditions of foliar spraying with salicylic acid, and in the control treatment (without use), the amount of these traits reached their minimum. Among the investigated plants, bean and mung bean plants had the highest yield. This The plants had higher number of capsules, number of seeds per capsule, weight of 1000 seeds, oil percentage, oil yield, seed yield, biological yield and protein percentage. The results of the interaction showed that the most investigated traits were under the conditions of foliar spraying with salicylic. The acid was applied to beans and mung bean and in the conditions of foliar spraying with sorbitol and mannitol to beans. |
