The effect of deferent level of nitrogen fertilizer on yield and quality of deferent cultivars of sugarcane (succharum officinarum L)

Abstract

Five cultivars of sugarcane (succharum officinarum L.) (CO331, mission-1, CP52, CO976 , CP68) were planted at sugar production company south Missan, to investigate the response of four levels of nitrogen fertilizer (zero, 80, 160, 240 KgN/ha). The experiment design where R.B.C.D with four replication treatment arrangement were in split plots, this results indicated that the cultivar CO331, gave the highest rate of plant height (156.25 cm) , weight of stem (1420 gm), weight can yield (114.28 t/ha), sucrose yield (4.2 t/ha) , % drix of juice 6.31 % , and proportion of fiber (13.65 %) while the interaction between the cultivars and nitrogen fertilizer, gave the CO331 and 240 kgN/ha highest rate of weight stem (1643 g), weight can yield (133.32 t/ha), sucrose of yield (16.97 t/ha) proportion of sucrose and proportion of fiber (13.9 %).
