C. During germination process the appropriate bacterial fertilizers were applied to the
cotton seeds and planted to the appropriate field plots.
3.6 Field experiment
Local cotton variety C-6524 was used in this experiment. The planting density was 60 cm×15 cm. Irrigation, pest
and weed control were carried out on the conventional management for cotton. Conventional mineral fertilizers N,
P, K input rates range from 200; 140; 70 kg·ha
-1

respectively in all plots of the experiment. The parameters of
seed germination, shoot/root fresh and dry weight, plant height, the number of bolls, the cotton yield were
analyzed. The plants were harvested according to their maturity time, and then were used to estimate the yield
based on the plot yield.
3.7 Statistical procedures
Data were tested for statistical significance using the analysis of variance package included in Microsoft Excel 97.
Comparisons were done using Student’s
t
-test. Mean comparisons were conducted using a least significant
difference (LSD) test (
P
=0.05).
