The presented study was carried out at Kom-Ombo Agricultural Research Station farm during 2013/2014 and 2014/2015 seasons to determine the role of irrigation systems, seed quality and potassium (k) fertilizer levels in maximizing productivity and water used efficiency of sugarcane crop. The G.T. 54-9 variety (commercial variety) was used. The irrigation systems were alternate and traditional surface systems. Treated with hot water and untreated seeds were the seed quality. The K fertilizer levels were 0.0, 24.0, 48 and 72 kg/fed. The experiment design was randomized complete blocks with three replication arranged in split-split plots system. Plot area was 80 m2.
The results indicated that irrigation of sugarcane crop by alternate system, planting with treated seed and applying 48 kg K fertilizer gave the highest cane and sugar yields in both plant cane and first ratoon crops across the two successive seasons. Otherwise, irrigating of sugarcane crop by traditional surface system, planting with untreated seed without applying K fertilizer recorded the lowest cane and sugar yields in both seasons. Using alternate irrigation system save 5056.13 m3 and 5475.46 m3 in plant cane and first ratoon crops, respectively and greatly improved water used efficiency |
