Productivity, Quality and Economics of Dual Purpose Barley (Hordeum vulgare L.) Varieties under Different Nitrogen Scheduling

The experiment was conducted at the Punjab Agricultural University, Ludhiana during 2007-09. The experiment was comprised of two varieties (i.e. RD 2552 and RD 2035) which were kept in the main plots and five nitrogen scheduling of T-1. 1/2N at basal + 1/2N immediate after cut (1/2N+1/2N), T-2. 1/2N at basal + 1/4N after cut + 1/4N after next irrigation (1/2N+1/4N+1/4N), T-3. 1/3N at basal + 1/3N after cut + 1/3N after next irrigation (1/3N+1/3N+1/3N), T-4. 1/3N at basal + 2/3N immediate after cut (1/3N+2/3N) and T-5. 2/3N at basal + 1/3N immediate after cut (2/3N+1/3N) was kept in the sub-plots treatments of split plot design were replicated thrice. Total nitrogen used was 80 kg N/ha. The variety RD 2035 gave numerically higher fodder yield than RD 2552 while reverse is significantly true for grain yield and crude protein. In 2/3N + 1/3N scheduling, the highest fodder yield was recorded was significantly higher than 1/3N + 1/3N+1/3N and 1/3N + 2/3N scheduling but statistically on par with 1/2N + 1/2N and 1/2N + 1/4N+1/4N scheduling. The highest fodder yield recorded in 2/3N + 1/3N scheduling was significantly higher than 1/3N + 1/3N+1/3N and 1/3N + 2/3N scheduling but statistically on par with 1/2N + 1/2N and 1/2N + 1/4N+1/4N scheduling. Highest crude protein recorded in nitrogen scheduling of 1/2N at basal + 1/4N after cut + 1/4N after next irrigation which was statistically on par with 1/2N at basal + 1/2N immediate after cut and 1/3N at basal + 1/3N after cut + 1/3N after next irrigation but was significantly higher than1/3N at basal + 2/3N immediately after cut and 2/3N at basal + 1/3N immediately after cut.
