Abstract: The present investigation entitled “Effect of Intercropping and Planting Methods on Yield, Nutrient content and Uptake by Sugarcane under Lateritic Soil of Konkan Region” was conducted at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.) during Suru season of 2015. The trial was laid out in a randomized block design. There were seven treatments which were replicated thrice. The treatments mainly comprised of Sole sugarcane with 90 cm spacing (T₁), Sole PRS i.e. 60 x 60 – 120 cm (T₂), PRS + groundnut (T₃), PRS + sweet corn (T₄), PRS + cabbage (T₅), PRS + amaranthus (T₆) and PRS + green gram (T₇). Results revealed that treatment sole paired row planted sugarcane (60 x 60 –120 cm) produced yield as compared to the conventional method of planting (90 cm in furrows) under study. Among the different treatments of planting methods and intercropping systems, paired row planted sugarcane intercropped with green gram recorded highest cane yield (89.03 t ha^-1), highest number of millable canes (78251.67), green top yield (11.66 t ha^-1) and trash yield (9.15 t ha^-1). Under different intercropping systems, the intercrop sweet corn recorded highest yield (8277 kg ha^-1) and sugarcane equivalent yield (146.38 t ha^-1). The nutrient uptake by crop was significant with nitrogen and potassium, but it was non-significant in case of phosphorus uptake. The maximum nutrient uptake recorded when paired row planted sugarcane intercropped with green gram. On the basis of results obtained during study, it can be concluded that the paired row planting method of sugarcane found to be more beneficial and profitable than their conventional planting (90 cm). The combination of sugarcane intercropped with sweet corn in the paired row planted sugarcane (60 x 60 –120 cm) found to be more remunerative followed by sugarcane intercropped with cabbage.
