Abstract:
The field experiment was carried out during the period from March to June 2022, with the aim of studying some growth indicators of wild wormwood seedlings Artemisia herba-alba Asso that were collected from Al-Deir area, Alswayda governorate, and cultivated in the village of Sama Al-Baradan in the same governorate, in the monoculture and intercropping with lentils Lens culinaris Medik. The results showed that the indicators of wormwood growth (the length and diameter of the plants) were increased insignificantly in the intercropping compared to the monoculture, but the % dried weight of wormwood decreased insignificantly in the intercropping to 53.1%, while it was 58.5% in the monoculture. As for lentils, the weight of 1000 grains/m2 decreased significantly in intercropping to 210g/m2, while it was 303.3g/m2 in the monoculture, but the harvest index increased insignificantly to 60.7 in intercropping, while it was 59.4 in the monoculture of lentils, and the LER (Land Equivalent Ratio) was 1.42. The experiment showed a potential allelopathic inhibitory effect of A. herba alba on the weeds in the studied area.
