Effect on growth and yield of wheat varieties under furrow irrigated raised bed system (FIRBS) by different methods of nitrogen placement

A field experiment was conducted during rabi seasons of 2001–02 and 2002–03 under farmers’ participatory research approach at village Khera Murar of Bawal block in district Rewari (Haryana). The experiment consisted of three nitrogen placement methods (N fertilizer applied in furrows only, N fertilizer applied on top of bed only and N fertilizer broadcasting) in main plots and six varieties (WH-147, WH-283, C-306, PBW-343, WH-896 and HD-2687) in sub plots of split plot design having four replications. Application of N on top of bed caused an increase of 12.5 and 28.8 per cent in grain yield, 11.9 and 28.2 per cent in straw yield over broadcasting and application of N in furrows, respectively during 2001–02. Corresponding increases for 2002–03 were 11.5 and 30.3 per cent for grain, 11.2 and 29.2 per cent for straw yield. PBW-343 produced significantly higher grain yield over all other varieties except HD-2687.
