Due to plants cannot relocate, they adopt allelopathy as a survival strategy when environmental conditions are unfavourable. This ecological phenomenon consists of releasing chemical compounds into the environment that can positively or negatively affect the growth and development of neighbouring plants. One of these chemicals is L-Dopa (L-3,4-dihydroxyphenylalanine), which is not an amino acid and is mostly in mucuna and broad bean plants. Weeds are an important problem in regions like Samsun, where winters and springs are rainy and warm. However, the broad bean has less weed density than other plants. This study was planned to determine the relationship of this situation with the L-Dopa production feature of broad beans. In the experiment, Lara variety, 5 different treatments (weedless control, weed control, 1 time hoe, 2 times hoe, 3 times hoe) were used in a randomized block design with 3 replications. Sowing was done on November 3, 2022, with 50 cm row spacing. One week after the last hoeing (April 4, 2023), samples were taken from the roots and stem parts of the plants for L-Dopa analysis. Both fresh pod and dry seed observations were made in the plots. In the observations, weeds belonging to other families (Veronica sp, Scandix pecten-veneris, Lupinus sp, Cirsium arvense, Fumaria officinalis etc.) were more common than grasses. It has been determined that the plant height is 99-131 cm, and it is the longest in weed control. The fresh pod yield was between 5186-7504 kg per decare, and the highest was obtained from the weedless control, the dry seed yield was between 375.9-481.5 kg, and the highest in hoeing 3 times. L-Dopa analyses are not yet complete.
