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)] to study the effect of Effect of different establishment techniques and planting geometry on uptake of nutrients and soil fertility status after harvest of sugarcane at Experimental block, Agricultural Research Station, Dhadesugur which falls under Northern Dry Zone of Karnataka (Zone-III) during 2016-17. Planting of two eye budded setts with dual row planting of sugarcane recorded numerically higher N and K uptake (337.4, 79.1 and 341.6 kg ha-1, respectively) followed by two eye budded setts with paired row planting (308.9, 72.4 and 310.1kg ha-1, respectively) and two eye budded setts with wide row planting (289.5, 69.1 and 297.7 kg ha-1, respectively). Lower uptake was noticed in three eye budded setts with normal row planting (221.3, 54.6 and 240.3 kg ha-1, respectively). Under different establishment techniques and planting geometries, growing sugarcane did not significantly influence the available soil nutrients at harvest. However, three eye budded setts with normal planting recorded numerically higher N, P and K availability followed by chip bud setts with wide row planting. Lower N, P and K availability was recorded in two eye budded setts with dual row planting.
