Abstract

One of the important factors in crop management decisions in order to obtain high YIELD with optimum quality is PLANT DENSITY for different PLANTING DATEs. In order to investigate the effects of delayed PLANTING DATEs and PLANT DENSITY on YIELD and YIELD components in COTTON (cv. siokra), an experiment was conducted in 2002 at COTTON Research Station of Karkandeh-Kordkoy. The experiment was a split-split plot in randomized complete Blok design with four replications. Three PLANTING DATEs (May 15, May 31 and June 22) were allocated to main plotes, two row spacing of 60 and 80 centimeter and three plant distance of 10, 20 and 30 centimeter were levels of second and third factors, respectively. Results showed that with delay in PLANTING DATE, YIELD and number of boll per square meter decreased but boll weight and number of seed per boll increased. Lower number of boll per square meter, more shedding of productive organs and low boll maintenance were the main reasons of YIELD reduction by delayed PLANTING DATEs. The first plating date compared with the second and the third PLANTING DATEs produced 25% and 58% more YIELD, respectively. There was a positive correlation between boll number per square meter and YIELD. Optimum PLANT DENSITY (plant density that had the greatest YIELD) was 13.8 plants per square meter for normal sowing date and 9 plants per square meter for the latest sowing date. For the second sowing date there was no response to PLANTING DATE.
