In field experiment at Sahiwal, Pakistan conducted during winter 2006, the effect of plant spacing 15cm, 22.5cm and 30cm on the yield of three recently approved varieties of cotton CIM-496, CIM-534 and MNH-786 was investigated. Effect of cultivars and different plant spacing was significant in yield and yield components except in quality parameters like Ginning out turn. Statistically same seed cotton yield was produced by CIM-496 (2488 kg per ha) and MNH-786 (2400 kg per ha) while minimum yield was produced by CIM-534 (2109 kg per ha). Plant height, number of sympodial branches per plant, monopodial branches per plant, number of bolls per plant and average boll weight was significantly higher in CIM-496. Significantly maximum seed cotton yield was obtained when crop was sown at 22.5 cm plant spacing.
