eeds as \7el1 as on yield and on some c:gronomie characters ~ize plant s of th c variety ”knerican-Early”. In
the residual effects of the above herbicides with rate8 on the growth and yield of the succeeding fieldbean crops were a so studiedo
The first ey.periment \las conducted to investigate the of the mentioned four herbicides used indiviicomb~nations compared with hand-hoeing on associated wceds~ The experiment was laid block system and consisted of 15
