Abstract

Animal husbandry occupies an important role and there is a big gap between demand and supply of forage. As the problem of the supply of feed and forage has become so serious due to the increasing number of animals and the limited land resources, and the expense of feeding makes up around 65-70% of all livestock production. So, keeping these things in view a field experiment was conducted 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. Experiment was laid out in split plot design with four replications. The goal of this study was to look into how the nitrogen dose and seed rate affect growth of dual-purpose barley. Based on the research investigation, it was found that nitrogen dose and seed rate both had significantly influenced the growth of dual purpose barley. Among nitrogen doses, 90 kg/ha being at par with 75 kg/ha recorded significantly higher plant height, dry matter accumulation, crop growth rate and leaf area index (2.64) at all stages of crop growth than nitrogen dose of 60 kg/ha, respectively. Progressive increase in the days taken to booting, heading and maturity was recorded with increase in nitrogen doses from 60 to 90 kg/ha. Among seed rates, 125.0 kg/ha closely followed by 112.5 kg/ha recorded significantly higher plant height, dry matter accumulation, crop growth rate and leaf area index (2.85) at all stages of crop growth than seed rate of 87.5 kg/ha, respectively. Significant increase in plant population was recorded with increase in seed rate from 87.5 to 125.0 kg/ha.

Conclusion

Based on field research experiment, it is concluded that increasing nitrogen dose from 60 to 90 kg/ha progressively increased growth of dual purpose barley but delayed maturity. Among seed rates, 125.0 kg/ha closely followed by 112.5 kg/ha recorded significantly higher plant populations, plant height, dry matter accumulation, crop growth rate and leaf area index at all stages of crop growth than seed rate of 87.5 kg/ha, respectively. So, to obtain higher growth for dual purpose barley (green fodder cut at 55 DAS and left after that for grain production), variety BH 946 should be sown using optimum seed rate of 125.0 kg/ha and nitrogen dose of 90 kg/ha.
