Abstract: A field experiment was conducted at Zonal Agricultural Research Station, University of Agricultural Sciences, GKVK Bengaluru during kharif- 2016 and summer 2017 to develop suitable planting geometry and nutrient management practices for maize based intercropping system. The experiment was laid out in a Randomized Complete Block Design with three replications using factorial concept involving different planting geometry, intercrops and nutrient management practices. The results revealed that between the planting geometry, paired row planting of maize (30/90×30 cm) has recorded significantly higher kernel yield (7686 kg ha-1), stover yield (8748 kg ha-1) and total nutrient uptake viz., nitrogen (143.68 kg ha-1), phosphorus (38.43 kg ha-1) and potassium uptake (145.39 kg ha-1). Among the intercrops, kernel yield, stover yield and nutrient uptake were found to be non-significant. Between nutrient management practices, base crop RDF + proportionate RDF for intercrops has recorded significantly higher kernel yield (7452 kg ha-1), stover yield (8950 kg ha-1) and total nutrient uptake viz., nitrogen (143.68 kg ha-1), phosphorus (38.43 kg ha-1) and potassium uptake (145.39 kg ha-1).
