- Abstract
Two field trials were performed at Tamiya Experimental Station, Fayoum Govemorate Egypt , during 2012 and 2013 seasons , to study the competitive ability of some maize hybrids in associated weeds by modification of crop density .The experiment included: Three hill distances (25,30and 35 cm apart) on one side of ridge at approximately 28000,23333 and 20000 plants I fed ,Three weed control treatments, one hand hoeing ,hand hoeing twice and the unweeded (control) and Three maize hybrids , i.e. , T.W.C.310, T.W.C.1100 and T.W.C. Nefertiti 3. Results showed that all weeded treatments significantly depressed weed growth comparing to the unweeded one .application of hoeing caused significant increases in plant height, ear height ,number of ear /plant , all ear characters , and grain yield I feddan . Moreover, two hoeing superiored one hoeing in all characters. Each increases in hill distances resulted in increasing - total weed dry weight, ear height, number of ear /plant ,ear length ,ear diameter, grain number I ear ,ear weight, grain weight /ear, 100- grain weight and grain yield I feddan .Neffertiti 3 surpassed other hybrids in all grain characters and grain yield I feddan .While T W C 1100 recorded the lowest values.
