Abstract

The aim of this research is studing three plant densities (one plant in ped ,two plant in ped and three plant in ped ) on the characters for five genotypes of cotton planting in April 2007 in two locations (Hawija and Sherqat) in R.C.B.D design in split plot system , the main plot contains varieties and the sub plot contains number of plants .All the genotypes showed high significance in 1% level except number of fruit branch which showed significantly differences in 5% level .percentage of ginning showed significant
differences in 1% level for the densities of plant .
The interaction between densities and varieties showed highly significant differences for all characters in 1 % level expect weight of the boll weight showed difference in 5% level . Also the results showed that the variety (Dun 1047) highly significant differences in the yield and number of bolls and number of branching in two locations.
The differences were non significant in the interaction (variety X densities ) for the number of vegetative branches and percentage of ginning of the two locations and the number of days of flower opening in Sherqat location .
