Abstract: A field experiment was conducted during Kharif 2010 under irrigated condition on red sandy loam soil to study the effect of spacing and nutrient levels on growth, yield and economics of Quality Protein Maize at Zonal Agricultural Research Station, Visweshwaraiah Canal Farm, Mandya. The result indicated that, the maize yield was higher in closer spacing of 45 cm 30 cm (4921 kg ha-1) compared to wider spacing of 60 cm 30 cm (4556 kg ha-1). Among different nutrient levels 125 % RDN recorded significantly higher grain yield (5143 kg ha-1) which was on par with 100 % RDN (4829 kg ha-1) and 150 % RDN (5087.93 kg). Whereas 75 % RDN recorded lower grain yield (3893.49 kg). With increase in nutrient dose from 100 % RDN to 125 % RDN, the grain yield was increased by seven per cent. Significantly higher B: C ratio was recorded with nutrient level of 125 % RDN (2.12) which was on par with 100 % RDN (2.11) and 150 % RDN (1.93). Whereas 75 % RDN recorded lower B: C ratio (1.85). Significantly higher netreturn (Rs.40086 ha-1) was recorded with T3 (45 x 30 cm +125 % RDN) treatment, followed by T4 (45 cm x 30 cm + 150 % RDN) Rs.38770 ha-1 and T2 (45 cm x 30 cm + 100 % RDN) Rs.37305 ha-1. Significantly lower net return was recorded with T5 (60 cm x 30 cm + 75 % RDN) treatment, Rs.25163.
