A Field experiment was carried out in a black clay [the soil was slightly alkaline pH (8.23), low in EC (0.20 dSm-1) and organic carbon (0.43%), low in available nitrogen (166.8 kg ha-1), high in available phosphorus (55.0 kg ha-1) and available potassium (300.5 kg ha-1)] soil to study the growth, sugar yield, quality and economics of sugarcane under different establishment techniques and planting geometries at Experimental block, Agricultural Research Station, Dhadesugur which falls under Northern Dry Zone of Karnataka (Zone-III) during 2016-17. Ten treatments were evaluated in different planting techniques and planting geometries in randomized block design with three replications. Among different treatments Two eye budded setts with dual row planting (30 cm-150 cm-30 cm) was recorded significantly highest sugar yield (15.2 t ha-1), green biomass yield (16.2 t ha-1), number of leaves (20.7 plant-1), leaf, stem and total dry matter production (72.6, 342.1 and 414.6 g plant-1, respectively) and which was on par with Two eye budded setts with paired row planting (60 cm-120 cm-60 cm) and Two eye budded setts with wide row planting (120 cm). The lowest sugar yield (10.4 t ha-1), green biomass yield (11.9 t ha-1), number of leaves (17.0 plant-1), leaf, stem and total dry matter production (61.4, 320.6 and 382.0 g plant-1, respectively) was recorded with Three eye budded setts with conventional planting (90 cm).While brix %, pol %,purity co-efficient % and commercial cane sugar % remained non-significant by different planting techniques and planting geometries. Two eye budded setts with dual row planting recorded higher gross returns (₹ 411493 ha-1) followed by two eye budded setts with paired row planting (₹ 390780 ha-1) and two eye budded setts with wide row planting (₹ 385320 ha-1).
