Abstract

Two field experiments were conducted at research station in Safsaf at EL-jabal Al-Akhdar to study effect plant population: 9.52, 13.33, 20 and 33.33 plant m2 and the effects of weeds cultivation numbers after one month and twice after first and Second month of seeding during the two seasons 2020-2021 and 2021-2022. The study layout in split plot design. population layed in the main plet, and cultivation of the weeds in the Subplots their area 2O4 (8m²), within four replications. The results revealed that, wead dominance efficient of bindweed & wild oat was not affected significantly due plant population (P.D), while significantly affected by weeds. cultivation (WC) in both the two seasons. Similarly in case of value index of weeds in the two seasons. Weed density and relative density as not affected by PD while significant only affected by WC in both first & second season. Covering index MDR) of bind weed and wild oat not affected by PD and significantly affected by WC in the two seasons. Similarly, marga leaf diversity index (Dmg) and Simpson & Shannon diversity index were not affected significantly by PD, while significantly with WC in both first & second season. Weeds dry weight at harvesting were not affected by PD, while affected Significantly by WC in the two seasons
