An optimum plant population can maximize the plant output so this field experiment was conducted to know about the Response of different planting density on various genotypes of cotton for yield maximization. In this experiment three cotton genotypes viz. hirsutum cotton (AKH-081), arboreum cotton (AKA-7) and Bt cotton (Balwan), with three plant densities level of 100 %, 150 % and 200 % of normal for respective genotype, were laid out in factorial randomized block design. Bt cotton Balwan recorded higher growth in terms of leaf area, dry matter weight and yield attributes plant-1. Plant height and sympodial branches plant-1 were significantly more with AKA 7. AKA-7 recorded maximum seed cotton yield (1715 kg ha-1) than Bt Balwan (1571 kg ha-1) and AKH 081(1466 kg ha-1). High density planting at 200% of normal density produced maximum seed cotton yield (1802 kg ha-1) at par with 150% of normal plant density (1679 kg ha-1). Normal planting density recorded the maximum harvest index (38.08%) and seed index (7.54) followed by high population densities of 150% and 200%. whereas balwan observed high seed index followed by AKH-O81 and AKA-07. Highest ginning out turn recorded by AKA-07 followed by AKH-O81 and Balwan but 200% planting density reported maximum ginning out turn than 150% and 100% planting density. Increased plant population compensated for fewer yield attributes plant-1 and cumulatively yield output was higher in conventionally close spaced genotype (AKA-7) and with the high density planting system.
