| Abstract | ||
| A study was conducted during the Summer Season 2007 at two locations , first one was in the field crop of Department , College of Agriculture – University of Tikrit , where as the second location was Awenat village ( 20 Km South of Tikrit ) .The experiment was carried out to investigate the effects of both , cultivar and plant densities in field characteristic , of Upland cotton plants . The cultivar varieties were ( Lachata , Montana , Nazley 87 , and Stoneville 474 ) . While density levels were ( 133333 , 88888 and 66666 plant h ) . Plant distances used were ( 10 , 15 , and 20 cm ) between one hole and the other , the distance between rows were 75 cm . A Factorial Experiment in a Randomized Complete Block Design ( R . C . B . D ) with three replicates for each treatment combination was used for the statistical handling of the data . Five field characteristic were investigated ( say them ) . The results obtained revealed a significant differences ( p < 0.05 ) between cultivars for all the traits with the exception of the number of vegetative branches plant at the first location ( Al Qadisiya ) .A significant differences between plant densities were found to be evident in plant height in Awenat location , number of vegetative and fruiting branches plant , number of days for first boll opening at both location. Cultivars × plant densities interaction effects were recorded to be significant on most of the traits . Location effects on most of the studied traits with the exception of the number of fruiting branches , days from planting to 50 % flowering percentage , days for first boll opening . | ||
