AbstractThis research was conducted to study the effect of alfalfa Medicago sativa residues (shoot) on germination and growth of two legumes species Vigna unguiculata and Cicer arientinum . Laboratory results showed that the aqueous extract of the residues at the concentrations5,10,15,20,25% w:v caused significant reduction in seed germination and seedling growth of the two legumes as compared with distilled water ,the less germination was recrded 32% at the concentration 25%in Cicer arientinum seeds also the less plumule and radical length recorded as 0.23,0.10cm in Cicer arientinum at same concentration.
The results of green house experiment showed inhibition in seed germination and growth of the two legumes growing in the soil containing alfalfa residues added at the ratio 10%w:w and incubated for (0,1,2) weeks as compared with control (without residues) ,the less germination recorded as 65% in Cicer growing in the soil containing resdues zero incubation.
Keywords:Allelopathy,alfalfa, Cicer arientinum, Vigna unguicula.
