SUMMARY
A field experiment was conducted at Research Farm of CCS Haryana Agricultural University, Hisar
(29010’ N latitude 75046′E longitude and 215 m altitude) during 2009-10 and 2010-11. The experiment was laid out in split plot design comprising two varieties (V1–RD 2552 and V2–RD 2035) in main plot and five nitrogen schedules (T1–½ at basal+½ immediate after cut, T2–½ at basal+¼ immediate after cut+¼ at next irrigation, T3–1/3 at basal+1/3 immediate after cut+1/3 at next irrigation, T4–1/3 at basal+2/3 immediate after cut and T5–2/3 at basal+1/3 immediate after cut) in sub plots, replicated thrice. Results revealed that variety RD 2035 recorded with 5.6 per cent green fodder yield, 12.4 per cent grains/earhead, 10.0 per cent grain yield and 9.4 per cent grain equivalent yield higher than RD 2552. Among different nitrogen application schedules, highest green fodder yield was obtained when nitrogen was applied in two splits (2/3 at basal+1/3 immediate after cut) whereas highest grain yields of 44.1 and 47.3 q/ha during 2010 and 2011, respectively, were recorded when nitrogen was applied in three equal splits i. e. 1/3 at basal+1/3 immediate after cut+1/3 at next irrigation.
