Sugar cane is one of the most important field crops in the tropics. Sugarcane is grown is not less than 105 countries and presently it covers a total acreage of about 19 million hectares for a world production of approximately 1.3 billion metric ton of cane and 127 million ton of sugar. Sub surface drip irrigation is the most advanced method of irrigation, which enables the application of small amounts of water to soil through the drippers placed below the soil surface with discharge rates. Row spacing has a direct effect on plant population. It plays a distinct role in the amount of solar radiation intercepted and density, hence, crop canopy development which in turn affects photosynthesis and ultimately the dry matter produced by plant. Based on this view, field experiment was carried out at Sugarcane Research Station, Cuddalore to optimize the row spacing and plant geometry for mechanized cane cultivation under sub surface drip fertigation system. Sugarcane variety viz., CoC 24 was in ten row spacing’s of 120,135,150,and 180 cm with each in single side and double side planting treatments were applied. A Randomized block design with three replications was used. Results revealed that widening spaces between rows of sugarcane from 120 up to 180 cm resulted in a significant and gradual increase in bio metric observation and yield parameters. Row spacing at 120 cm with double side planting gave the highest values of cane yield, juice quality and commercial cane sugar. The double side planting registered more tiller population than single side planting. The double side planting registered more cane yield. Among the treatments, the maximum cane yield of 155.35 t/ha was observed in the treatments by the row spacing of 120+40 cm double side planting.
