ABSTRACT: Nitrogen fertilization plays a very important role
for crop productivity. New developed wheat varieties need proper fertilization
for improved crop productivity. The present study was carried out to quantify,
the effects of nitrogen derived from urea and FYM on the four newly developed
wheat varieties i.e. Siran-2009, Ata
Habib, Janbaz-2009 and Pirsabak-2008 for yield improvement, quality and soil
fertility status. The N treatments were control, 100% of the recommended
nitrogen from urea as well as FYM, and 50% from each source. The experiment was
carried out at New Developmental Farm, Khyber Pakhtunkhwa Agricultural
University Peshawar Pakistan, during Rabi 2011-2012. Results of the data showed
that Janbaz-2009 was more responsive to biological yield (11,011 kg·ha-1),
grain yield (4339 kg·ha-1), and nitrogen use efficiency
(14.8%), whereas Siran-2010 performed better for grain N contents (2.31%).
Plots having both urea and FYM had improved biological yield (11,958 kg·ha-1),
and grain yield (4901 kg·ha-1). Urea application had
improved straw N contents (0.92%) in addition to Mix application of urea and
FYM (0.93%). Mix application of both sources and sole FYM had higher grains N
content (2.25%), whereas control plots in addition to mix application had
improved nitrogen use efficiency (14.8%). Siran-2010 and Janbaz-2009 performed
better in FYM and mix FYM and urea plots for most of the parameters. It was
concluded from the experiment that Janbaz-2009 had improved yield and yield
components, whereas Siran-2010 had improved the grain N content. Similarly, Mix
application of FYM and urea had improved crop productivity, soil fertility and
grains as well as straw N content. Thus wheat varieties Janbaz-2009 sown in mix
FYM and urea is recommended for general cultivation in agro-climatic condition
of Peshawar.
