- Abstract
Field tests were directed to test the allelopathic capability of two sunflower (Helianthus annuus L.) Asgria and fire cultivars on sidekick weeds and weeds developed in expansive bean (Vicia faba L.) edit and to decide the genetical bases of allelopathic qualities in the test cultivars. The principal explore was directed to test whether the variety in weed populace and biomass between the stands of Asgria and fire sunflower cultivars, which was seen in the field, was because of contrasts in their allelopathic potential. Results uncovered that the asgria cultivar essentially stifled thickness and dry weight biomass of friend weeds over the fire cultivar by 39.6 and 58.7% separately. The second field test was led in the field to test the impacts of buildups of tried Sunflower (Helianthus annuus L.) cultivars on weeds developed in expansive bean (Vicia faba L.) field and development and efficiency of wide bean edit. The outcomes demonstrated that weed thickness decreased by 35.8 and 54.7% of control by consolidating asgria buildup at rates of 3 t ha-1 and 6 t ha-1, individually. While the diminishments were 20.8 and 48.8% of control by fusing of previously mentioned buildup rates of fire cultivar. Mix of half full rate of Trifluralin herbicide and sunflower deposits at 6 t ha-1 fundamentally decreased weed dry weight by 62.8 and 41.9% contrasted and control, separately in Asagri and Flame The lessening in weed thickness stayed higher by asgria than by fire buildups. Over the ground biomass of weeds was likewise lessened fundamentally by fuse of buildups of both sunflower cultivars and the diminishment expanded with the expanded deposit rate; be that as it may, asgria was the most weed biomass smothering cultivar contrasted with fire cultivar. Be that as it may, the concealment of weed populace and dry weight biomass was additionally enhanced when the plots were treated with half of named rate of herbicide and corrected with sunflower buildups. Combination of lessened herbicide rate and sunflower deposits at 3 t ha-1 and 6 t ha-1 brought about more weed concealment than sole use of the regarded sunflower buildups. The outcomes likewise uncovered that weed concealment was specifically converted into yield of expansive bean. Use of Trifluralin herbicide at half rate in plots altered with sunflower deposit at rates of 6 t ha-1 brought about comparative organic and grain yields, number of spikes per plant, number of grains per spike and collect record was accomplished by the name herbicide rate treatment. Greatest yield was acquired in plots got asgria deposit at 6 t ha-1+50% of mark rate of trifluralin in asgria cultivars buildups took after by plots revised with asgria deposit at 6 t ha- 1 the previously mentioned rates.
