Abstract
The experiment was carried out in the field of AL- Musaiab Technical Institute for the years of 1997/ 1998 , to study the influence of some herbicides and hand weeding on the yield and yield components of ground nut . Treatments included hand weeding , Triflian ( Trifluralin ) 48% ( 600cm3 / D ) preplanting , Fusilade ( Fluazifop – butyl ) 25% ( 500cm3 /D ) post emergance , Triflian 48% ( 600cm3 /D ) preplanting and Fusilade 25% ( 500 cm3 / D ) post emergance , Triflain perplanting and fusilade twice ( The first was post emerganc and the second after one month ) and control , complet randomized block design was used .Result of this study indicated that the effect of the herbicides used on the annual narrow and broad leaves weed such as Echinochola , colonum . setayia , glauca , Dactyloctenium aegyptium , Amaranthus reteroflexus , portulaca , oleracea . Fusilade was highly effective on Cynodon dactylon and Cyperus rotundus . But use of herbicides did not show any effect on convolvulus arvensis . The treatment of herbicides and hand weeding had significant effect on the number of pod / plant , seed number / plant , weignt of 100 seed , yield of seed kg/ha . The best treatment was hand weeding and the use of Triflian preplanting and Fusilade post emergance , with regrard to all characteres of ground nut .
