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.
