Two field experiment were earned out during winter seasons 2004/2005 and 2005/2005 In Experimental Station of National Research Center, Shatakan District.
KaIubi Governorate Egypt Th. aim of the study was to examine the response of
wheat cultivar Sakha-93 to 3 weed control treatments and twa sowing methods The
experwnent included 6 treatments which were the Combmations of two sowing
methods 1. In ridges 2. rows and response cf wh.a cultivar Saklia.93 to 3 weed
control treatments lUweeej (control); 2Hand weeding twice at 30 and 60 DAS 3-
Chemical weed control by Panther 55% Sc at post emergence The reatmencs were
arranged in split plot design in four replicates, sowing methods in main plots and weed
controi treaظn an sطo Combined analysis tead for the two seasons,
Data indicated that sowing wheat cv Sakha.93 in ridges surpassed in rows
for no, of tillers spdcesn’; spdc. length . spik. weight, grains weight/spike; gran;
