Abstract:
An experiment was carried out by designing randomized complete block with three replications, at the Scientific Agricultural Research Center in Salamieh (Syria) during 2018-2019. We are studied the effect of several rates of the Aclonifen herbicide in controlling the white mustard weed (Sinapis alba L.), and on the formation of bacterial nodes on the roots of lentil crop plants, and its productivity. The results showed that the three herbicide rates (600, 900, 1200 g a.i./ha) of Aclonifen herbicide had controlled white mustard (Sinapis alba L.) and increased the number of bacterial nodes on lentil roots compared to weedy control, with a preference for the highest rate (1200 g a.i./ha) with the highest efficiency (69.2%) according to the dry weight of the weeds, and with the highest number of bacterial nodes (13.3 node/plant). The weed free treatment gave the best weed control and the highest number of bacterial nodes (13.8 node/plant), and the highest biological yield (hay and seeds) of lentil with significant differences compared to other treatments, and increased the productivity of hay and seeds by 8 times compared to the weedy control, followed by the rate (1200 g a.i./ha) of Aclonifen used, with 4 times more for hay and 6 times more for seeds.
Key words: Aclonifen herbicide, white mustard, lentil, bacterial nodes.
