Grains of wheat crop gathered from five fields harvested by combine (class 520L) style al El-jabal Al-Akhadar during 2016 season. Each sample were 1kg represent each field were screened by mesh 2mm. 5gr from each screening replanted in a pot 3L capacity filled by organic soil and irrigated as needed. The study was designed by RCBD with 5 replicates.
Results revealed significant c4 saddling pot; convolvulus a ravens (23.4 Seedling/pot) Brassica compestris (18.2 Seedling/pot) Medic ago polymorpha (21.8 Seedling/pot and fumaria deusi flora plastochrom inclex , PI) recorded significant affect, (P<0.01). Serial a ffect were carvensis <M polymorpha <B. composters <L escolenta <F. densiflora based on the mesh were 2, 3, 5, 6 and 7mm of that species respectively weeds species exhibited significant differences of biomass (P<0.01). Greatest 50.53g/pot of B. compestris comparing & the least 13g/pot from F.densiflora. This study showed that if the field infested by such species the harvested gracias needed & rescreening when that grains used in shedding & avoid multiplications of such species in the field.
