Abstract:
Improving production
through better agronomic management is
continued to feed ever-increasing
population. The objective of this study was
to quantify the effect of N on maize seeded
in line or broadcasted. Treatments included
four level of urea nitrogen (N), i.e. 0, 60,
120 and 180 kg ha-1 and two sowing
techniques, i.e. drill sowing (improved) and
broad cast (farmer practice). Improved
method of sowing had improved yield and
yield contributing parameters whereas
emergence m-2 and biological yield was
higher in broadcast method of sowing.
Increasing N application had increased
biological yield, number of plants at harvest
and grains ear-1 linearly. Cobs per plant,
grain yield, 1000 grains weight and harvest
index showed sigmoid response to N
application and was maximum at 120 kg N
ha-1. Sowing of maize seed in line method
and receiving 120 kg N ha-1 had increased
grain yield by 45% over broad cast method
of sowing receiving the same dose of
nitrogen. However, the farmer practices
method had increased the forage (straw)
when received higher amount of N, i.e. 180
kg N ha-1. Thus, it is concluded from the
experiment that application of 120 kg N ha-1
and seed sown in line had increased the
yield and yielding parameters, compared to
other treatments and is, therefore,
recommended for general cultivation of
variety Azam in agro-climatic condition of
Peshawar.
