| Abstract | ||||
| Two field experiments were conducted at Ciba-Geigy Experiment Station in Qaha region during 1996. The first was after Berseem crop while the other was after fallow. Pix was effective in limiting plant height and leaf area significantly decreased by any rate or time of application. Number of bolls set, dry weight of stem and branches and roots per plant were increased by spraying Pix. These increases were significantly attained by all treatments which cultivated after Berseem crop or fallow. However squares and boll shedding percentage were decreased significantly by Pix treatments. Seed index, numberr of open bolls, seed index, number of open bolls seed cotton yield/F and seed cotton yield/plant were significantly increased by Pix treatments. Number of intemodes, fruiting branches, lint % and Earliness were not affected by spraying Pix. Atonik foliar application was effective in increasing leaf area, number of boll set, dry weight of shoot, root and leaves, in both experiments significantly. Atonik also increased significantly seed index, number of bolls, seed cotton yield. Boll weight, lint %, and Earliness of yield, were not affected by Atonik treatments. | ||||
