Abstract: Investigation into the effect of different geometric arrangements on morpho-qualitative traits of a cotton cultivar NIAB-86 were carried out at the University of Agriculture, Faisalabad. The geometric arrangement comprised 60, 70, and 80 cm spaced single row and 90, 105 and 120 cm double-row strip plantation. Plant population of about five plants m–2 arranged in the pattern of 90 cm spaced double-row strips with 30 cm space between the rows of strip (30/90 cm) appeared to be optimum for getting good yield of seed cotton. The maximum seed cotton yield of 1693 kg ha–1 was obtained from the crop planted in 90 cm spaced double-row strips against the minimum of 1431 (kg ha–1) in case of 60 cm spaced single-row plantation. However, both fibre length and fibre strength were not affected significantly by the different geometric arrangements.
