The effect of soil treatment methods against dodder (Cuscuta sp.) in soybean cultivating field

In the paper, it was described the effectiveness of different tillage methods against dodder in soybean field. In the conditions of typical sierozem and sierozem-meadow soils, it was determined that the fight against the dodder gave good results when the soil was plowed with a two- tier plug at a depth of 0-40 cm in the 1st year, 0-24 in the 2nd year, and 0- 32 cm in the 3rd year. In this case, it was observed that the spread of dodder was reduced by 45.3-50.2 % compared to the control in proportion to the soil types, and the efficiency was 95.2-94.7 %. Organic amendments improved soil health parameters but were less effective in controlling dodder, achieving only a 50% reduction. Mechanical tillage was the least effective, with a 30% reduction in dodder density. Soybean yield was highest in chemically treated plots, followed by solarized plots, with organic amendments and mechanical tillage showing marginal yield improvements over the control.
