The production and use of common vetch has great potential, but the lack of approved
pesticides makes the success of cultivation difficult and unpredictable. The research was carried
out on sandy soil at the Nyíregyháza Research Institute of the University of Debrecen in Hungary
in April 2022. Five different herbicides, pendimethalin, metolachlor, flumioxazin, bentazon in
doses 5 L ha-1
, 1.4 L ha-1
, 0.06 kg ha-1
, 2 L ha-1
, respectively, and imazamox in four different
doses (0.6, 0.8, 1.0, 1.2 L ha-1
) were applied with the consideration of the ranges specified in the
Hungarian legislation. The results showed that the highest NDVI (Normalized Difference
Vegetation Index) values were obtained with flumioxazin compared to the other treatments. The
maximum harvested seed yield (194.1 kg ha-1
) was obtained with the application of flumioxazin
compared to the control treatment (132.5 kg ha-1
). Flumioxazin was also the best as it had the
fewest weeds per plot and the lowest phytotoxicity score. Although pendimethalin approached
the cleaned and harvested average seed yield of the control plots with 121.3 kg ha-1
, it did not
feature prominently in the other indicators. With regard to plant trash after cleaning of vetch seed,
the highest plant trash (179.4 kg ha-1
) was obtained with bentazon. Pendimethalin had the highest
percentage ratio between seed yield ha-1 and plant trash ha-1 (61.8%), followed by flumioxazin
(60.7%). The results also showed that there was a positive correlation between NDVI values and
seed yield and a positive correlation between NDVI values and plant trash, while there was a
negative correlation at the 0.01 level between NDVI values and phytotoxicity.
