An experiment on effect of row spacings and fertilizer levels on yield and popping quality of pop sorghum genotypes was carried out during kharif 2002 at Main Agricultural Research Station, UAS, Dharwad, Karnataka. Of the three genotypes tested, Pudakalakatti out yielded all other genotypes, but Shiggaon produced superior quality pops. Higher grain yield (1410 kg ha-1) and stover yield (23.40 t ha-1) were recorded with 45 cm row spacing followed by 60 cm rows and the lowest values were recorded in 37.5 cm rows. Good popping quality was obtained in medium to wider row spacings (45 cm and 60 cm). Application of 80:40:40 kg N, P2O5 and K2O ha-1 significantly increased the yield attributes, grain yield, stover yield and net returns, whereas the B:C ratio was higher with the application of 40:20:20 kg N, P2O5 and K2O ha-1.
