ABSTRACT
Two filed experiments were conducted at San El- Hagar , El-Sharqia
Governorate ,Egypt in two successive growing seasons of 2015/2016
and 2016/2017 to investigate the effect of some sowing methods
(broadcast and drill ) and some weed control treatments(Thirteen weed
control treatments were used as follows:1- Unweeded (control),2- Hand
weeding once , 3- Granstar ,4-Topik 5- Panter, 6- Ballas ,7- Tournex
,8- Granstar + Panter,9-Topik+panter ,10- Granstar + Ballas,11-Topik
+Ballas,12- Granstar +Tournex and 13-Topik +Tournex ). on associated
weed species and wheat productivity .The obtained results showed that
drill sowing method gave the lowest total dry weight of annual weeds
and the highest number of spikes /m2 , grain weight / spike , grain yield /
feddan and straw yield / fed . Spraying wheat plants with mixed herbicide
from Topik +Tournex gave the lowest total dry weight of annual weeds,
on the contrary, it the highest values of number of spikes/m2, grain
weight of spike (g) , grain yield per feddan (ardab) as well as straw yield
per feddan( ton) . Sowing wheat with drill method and treated with
Topik +Tournex treatment gave the lowest total dry weight of annual
weeds, on the other hand , it gave the highest values of number of
spikes/m2, grain weight of spike (g) , grain yield per fed ( ardab) as well
as straw yield per fed ( ton).
