Yield and Economics of Dual Purpose Barley as Influenced by Various Nitrogen Dose and Seed Rate

Abstract

A field experiment was carried out during Rabi season 2019-20 at wheat and barley section research area of CCS Haryana Agricultural University, Hisar. The experiment was comprised of three nitrogen doses (N1-60, N2-75 and N3- 90 kg N/ha) as main plot treatments and four seed rates (S1- 87.5, S2- 100, S3- 112.5 and S4-125.0 kg/ha) as sub plot treatments. With four replications, experiment was laid out in split plot design. Based on the research investigation, it was found that nitrogen dose and seed rate both had significantly influenced the yield attributes and yield  of dual purpose barley Among nitrogen doses, 90 kg/ha being at par with 75 kg/ha recorded significantly higher grain yield (4895 kg/ha), biological yield (12220 kg/ha) and green fodder yield (3706 kg/ha) which were 9.7, 12.0 and 15.1 percent higher than nitrogen dose of 60 kg/ha, respectively due to higher  yield attributes  i.e. number of effective tillers (85.08), number of grains per spike (44.15), number of spikelets per spike (23.10), spike length (7.47) and test weight (37.82) with nitrogen dose 90 kg/ha which were 8.5, 5.1, 7.9, 11.4 and 4.8 percent higher than nitrogen dose of 60 kg/ha, respectively. Among seed rates, 125.0 kg/ha closely followed by 112.5 kg/ha recorded significantly higher effective tillers (85.11), grain yield (4922 kg/ha), biological yield (12181 kg/ha), green fodder yield (3729 kg/ha) which were 8.0, 11.0, 11.8 and 16.7 per cent higher than seed rate of 87.5 kg/ha, respectively.
