Late Season Sugarcane Genotype as Affected by Irrigation Water Deficit at the Yield Formation Stage in Ferké, North-Eastern Ivory Coast

In order to evaluate sugarcane growth and yield response to irrigation water deficit imposed during the yield creation stage, a field trial was conducted in Ferké 2 Sugar mill plantations in northeastern Ivory Coast. The first ratoon harvest was a non-flowering late-season sugarcane cultivar (Co957). The study used a randomised complete block design with four water shortage treatments in three repetitions. It was discovered that the ideal water deficiency was 20% of typical watering treatment. That treatment resulted in a water use efficiency of 7.9 kg cane/m3, or 0.98 kg sugar/m3. A protracted dry season occurred during the yield formation stage, resulting in lower crop growth rates (0.2-0.4 cm/day) and cane yields (24.5-78.4 t/ha). Cane juice quality was notably excellent on the variety employed, which performed moderately under Ferké 2 farming settings, in keeping with the prevailing climatic circumstances.
