The effects of N (0, 40 or 80 kg/ha through urea) and P (0 or 20 kg/ha through single superphosphate) application on the performance of E. frumentacea cultivars (ER 64 and ER 72, and KI as the control) were studied in Udaipur, Rajasthan, India, during the kharif of 2004. ER 72 registered the greatest plant height at 40 days after sowing or DAS and harvesting stage or HS (78.3 and 102.60 cm, respectively); number of tillers at 40 DAS and HS (35.92 and 34.71/m row length); dry matter accumulation per plant at 40 DAS, 60 DAS, and hs (6.12, 10.39 and 18.26 g); grain weight (4.33); 1000-grain weight (3.58 g); grain yield (16.55 quintal/ha); and straw yield (62.49 quintal/ha). N at 40 and 80 kg/ha resulted in the greatest plant height (103.48 and 105.21 cm at HS), number of tillers (34.81 and 36.32/m row length at HS), dry matter accumulation (18.53 and 18.77 g per plant at HS), number of panicles (30.43 and 30.91/m row length), grain weight (4.35 and 4.48 g), 1000-grain weight (3.61 and 3.72 g), grain yield (16.64 and 17.00 quintal/ha) and straw yield (62.38 and 64.00 quintal/ha). The application of P enhanced plant height (106.20 cm at HS), number of tillers (36.29/m row length at HS), dry matter accumulation (19.10 g per plant at HS), number of panicles (31.47/m row length), grain weight (4.50 g), 1000-grain weight (3.78 g), grain yield (17.39 quintal/ha) and straw yield (65.24 quintal/ha). [1 quintal=100 kg].
