Abstract
The field experiment entitled, “Integrated nutrient management
studies in barley (Hordeum vulgare L.) was conducted during rabi season
of 2004-2005 at Research Farm of CCS Haryana Agricultural University,
Hisar with the objectives (a) to study the effect of different sources of
nitrogen and their integration on growth and yield of barley, (b) to study
the effect of different treatments on nutrient uptake and quality of barley,
and (c) to study the economics of different treatment. The experiment
was conducted with 14 treatments of different nitrogen sources,
Azotobacter, phosphorus solublizing bacteria in randomized block design
with three replications.
The periodic growth parameters (plant height, leaf area index, dry
matter accumulation and tillering) and yield attributes (length of ear
head and number of grains per ear head) increased with increasing dose
of nitrogen with 100 per cent N inoculated with Azotobacter and PSB but
had no effect on test weight. The grain and straw yield increased
significantly by increasing nitrogen dose with 100 per cent inoculated
with Azotobacter and PSB. Nitrogen application and Azotobacter and PSB
had no effect on harvest index. Residual nitrogen in soil increased with
increasing nitrogen dose i.e. 100 per cent inoculated with Azotobacter
and PSB. Nitrogen content in grain and straw increased significantly with
100 per cent inoculated with Azotobacter and PSB. Crude protein content
in grain increased significantly with 100 per cent inoculated with
Azotobacter and PSB. Vermicompost and inorganic fertilizer affected the
malt yield. Higher fertilizer of nitrogen led to significant reduction in malt
yield. Malt homogeneity, bold grain percentage increased significantly
with 100% inorganic fertilizer inoculated with Azotobacter and PSB as
compared to various treatments. Net income increased significantly with
increasing nitrogen dose with 100 per cent inoculated with Azotobacter
and PSB (Rs. 6231ha-1).
On the basis of one year results it may be suggested that barley
crop should be grown by inoculating seed with Azotobacter and
phosphorus solublizing bacteria 60 kg N ha-1.
