Abstract:
The present research
was aimed to study the effect of different levels of inorganic
fertilizer N on the yield and yield components of barley varieties at
KPK Agricultural University, Peshawar, Pakistan. The experiment was laid
out in randomized complete block design with split plot arrangements.
Barley varieties (local and sterling) were sown in the main plots
whereas different nitrogen levels (i.e. 0, 20, 40, 60, 80 and 100 kg ha-1)
were allotted to sub-plots. The results showed that different varieties
and nitrogen levels had significantly (p<0.05) affected plant height,
1000 grains weight, grains spike-1, straw yield, grain
yield, biological yield, grain and plant N. Maximum grain spike-1
, thousand grain weight and grain yield was recorded in sterling.
Taller plants, highest biological yield, straw yield, grain and plant N
was observed in local variety. Nitrogen applied at the rate of 60 kg ha-1
resulted in maximum grain spike-1, thousand grain
weight, biological yield, grain yield, grain and plant N.
