Özet
Increasing of cotton production and yield is very important for developing countries,because cotton is a raw material for textile industry.For this, it should be used the beneficial effects of suitable irrigation, fertilizing, and crop production techniques.Some of the production techniques increasing cotton yield, lint quality and decreasing production costs are, cotton production from seedlings, twin rows sowing technique, sowing to a stand, sowing under the plastic mulches, and fluid drilling of pre-germinated seeds.The purpose of this research are, a) the production possibilities of main crop cotton established from seedlings and established from single row and twin rows sowing techniques, and b) the production possibilities of second crop cotton directly from seeds or from seedlings.The research results about the main crop cotton showed that transplanting of seedlings had the potential to increase the yield and early-maturing though the effects were not significant.However, crops established from seedlings gave 14.37 percent higher earliness than crops established from seeds sown in a single row (conventional sowing).On the contrary, the earliness was equal in transplanted and twin rows drilled plots.The production techniques did not affect the lint quality, significantly.In the condition of Aegean Region, degree of boll opening of transplanted second crop cotton was 90.9 percent at the end of September.It could be produced the second crop cotton by transplanting at 90.9 percent boll-opening in Aegean region.Second crop yield obtained from drilled plots was found unsatisfactory, because the earliness (boll opening) was 12.84 percent.Yields of main crop cotton established from seedlings was 5,543 kg ha -1 averaged over second crop yield (only transplants, 3,966 kg ha -1 .Second crop cotton produced directly from seeds decreased dramatically because of the harvest delay.Transplanting of cotton seedlings provide about 15-30 days advantage.Earlier growth means earlier harvesting.Earlier cotton harvesting provides the opportunity to harvest the quality seed cotton with higher first-hand picking efficiency.
