Abstract: An experiment were conducted on the effect of colour plastic mulches on plant height, days to fifty per cent flowering, leaf area index under different irrigation levels. The treatments were laid out in split plot design with three replications and a non-mulched treatment as control. The plastic coloured mulches used were white on black, silver on black and black. The irrigation levels used were 60, 80, 100 and 120 per cent ET. The results indicated that the growth components of plant height, days to fifty per cent flowering and leaf area index were significantly influenced by drip irrigation levels. The maximum plant height (125.54 cm), least days to 50 per cent flowering (41.78days), highest leaf area index (3.20)80 per cent ET with white on black plastic colour mulch when compared to other treatments throughout the growing period
