Abstract :早植,適性な畦幅,深耕,標肥栽培,補植,堆肥施用,除草,培土,鍬によ地際刈り及びかんがい栽培した場合サトウキビの収量形質にどのような影響を及ぼすかについて検討した。その結果,早植区,深耕区,標肥栽培区,補植区,堆肥施用区および潅水区では発芽率及び単位面積当り分けつ数が対照区(バングラディシュにおける平均的農家の栽培の実状に合わせた試験区)より有意に優れていた。原料茎数の最高値は潅水区において得られ(68,900本/ha),次いで早植区が多かった。しかし,収量の最高値は標肥栽培区で得られ(54.00t/ha),対照区より37.80%の増収であった。一方,対照区では最低収量(39.20t/ha)を示した。シュクロース含量は早植区と堆肥施用区の10.90%が最も高かった。また,堆肥施用区では最も高い産糖量(5.83t/ha)を示し,対照区に比べて48.72%の増収であった。以上のように,サトウキビの収量形質は栽培法の違いによって大きな影響を受ける。
Ten agronomical practices such as early planting, optimum row spacing, deep trench, recommended rates of fertilizer, gap filling, use of organic manure, weed control, earthing up, harvesting by spade at ground level and irrigation were compared with control for their effects on yield components of sugarcane. Different practices showed their effects differently in varying degrees. Among them early planting, deep trench, recommended rates of fertilizer, gap filling, use of organic manure and irrigation showed significantly higher germination and tillers over control. The highest number of millable cane (68900/ha) was produced in the irrigated plot, followed by early planting (64300/ha), but the highest yield of cane (54.00t/ha) was produced in the recommended rates of fertilizer treated plot (37.80% yield was increased over control), while the lowest cane yield (39.20t/ha) was obtained in the control plot. Early planting produced cane yield 49.90t/ha (27.30% increased yield over control), followed by irrigation (48.60t/ha), where 24.00% yield was increased over control. The highest sucrose content was found (10.90%) in early planted cane and organic manure applied cane, followed by recommended rates of fertilizer applied cane (10.80%). The recommended rates of fertilizer also produced the highest tonnage of sugar (5.83t/ha, which was 48.72% increased yield over control), followed by early planted cane (5.54t/ha, where 41.33% increased yield was found over control). This investigation indicates that agronomical practices have positive effects on yield components of sugarcane.
