This paper had been presented for promotion at the University of Khartoum. To get the full text please contact the other at eltayebnimir@yahoo.comA field experiment was conducted during 2012/2013 at Guneid sugarcane research farm to evaluate the effects of the date of first irrigation on the growth of sugarcane (Saccharum sp.) first ratoon. After harvest of main sugarcane crop, four first irrigation dates (after 3, 9, 15 and 21 days) were applied and arranged in a completely randomized block design with four replications. The plant growth attributes studied were plant height, plant population, stem diameter, biomass fresh and dry weights. First irrigation date had significant effect on plant height, plant population, and stem diameter and insignificant effect on number of leaves/plant and biomass fresh and dry weights. Plant height, plant population and stem diameter were reduced with delayed first irrigation date. Application of the first irrigation after 3 days from harvest was the best date for the start of the ratoon growt
