Abstract

Two field experiments were carried out at El-Gemmiza Agricultural Research Station , El- Gharbiya Governorate Egypt, during  2010 and 2011 seasons to study the effect of power – I foliar spraying at three  concentrations  ( 1 cm3, 2 cm3 and 3 cm3 / liter water ) once ( at squaring stage) or twice ( at squaring and start of flowering or at start of flowering and full flowering stages ) comparison with untreated plants on growth, yield and yield components and some of chemical as well as technological characters of Giza 86 cotton cultivar. The results could be summarized as follow :- 1-Power–1 treatments significantly increased leaf chlorophyll a, b and total chlorophyll contents in both seasons, in favour of applying power – I at the rate of 2 cm3  / liter twice ( during square  and  start of flowering ) 2- Spraying power – I at any rate significantly decreased leaf reducing and total soluble sugar, while non-reducing sugars and N, P and K contents were increased with all power I treatments as compared with untreated plants in both seasons. 3- Applying power – I at the high rate (3 cm3 / liter water) twice ( during squaree and start of flowering stages ) gave taller plants with high number of fruiting branches per plant as compared with the other treatments. 4- Power – I at the rate of ( 2 cm3 / liter water) twice ( during square and start of flowering stages) gave the most significant increase in number of flowers and open bolls / plant in the first season, while at 3 cm3 / liter gave the highest number of flowers and open bolls / plant in the second season. 5-  All treatments with power –I increased boll setting percentage and decreased boll shedding percent in both seasons. 6- Power –I at all rates during growth periods significantly increased boll weight, seed index, earliness and seed cotton yield / fed. in both seasons as compared with control. 7- Lint % and fiber properties ( pressely index and micronaire value ) were  not   significant in both seasons.
