Two field trials were carried out at Sakha Agricultural Research Station during 1995 and 1997 seasons, using the new cotton cultivar Giza 89 which was planted on ridges 60 cm x 20 cm/one side, 60 cm x 25 cm/one side, 90 cm x 20 cm/two sides and 90 cm x 25 cm/two sides as main plots and received three N levels 40, 60 and 80 kg/f. as sub-plots. Combined data revealed that growing cotton plants on ridges 60 cm at one side (low stands) increased final plant height, number of monopodia and sympodia, lateral root ranks, root volume, additional fruiting branch bolls, retained bolls, fruiting sites, earliness %, open bolls, boll weight and seed cotton yield, while it decreased numbers of aborted sites, first sympodial position, percentage of bolls on monopodia, uno­pen bolls and percentage of plant losses at harvest, compared with planting on ridges 90 cm at both sides either at 20 or 25 cm hill spac­ing. Nitrogen application up to 80 kg/f. induced maximum values of final plant height, number of both monopodia and sympodia, aborted sites, additional fruiting branch bolls, retained bolls, fruiting ites, first sympodial position, percentage of bolls on monopodia, unopen bolls and boll weight. Adding 60 kg N/f. resulted in higher number of open bolls and seed cotton yield (Kintar/f.). N application had no influence on num­ber of lateral root ranks, root volume and percentage of plant losses at harvest. The interaction between sowing pattern and N level had insig­nificant effect on all traits studied in this study.
