Abstract

An experiment entitled “Phenology, growth and yield characteristics of maize as affected by row spacing and
nitrogen placement methods'' was conducted at Research Farm of Agronomy, The University of Agriculture
Peshawar, during kharif 2015. Randomized complete block design with split plot arrangements (RCBD split plot)
having four replications were used. Row spacing (45, 55, 65 and 75 cm) were allotted to main plots while nitrogen
placement methods (control, single side of the row, between the rows and both sides of the row,) were assigned
to sub plots. Maximum days to 50% flowering (54.8) and days to 50% tasseling (62.5) were recorded for 45 cm
row spacing while higher ear weight at maturity (76.4 g) and more number of grains ear-1 (376.4) were recorded
for 75 cm row spacing and grain yield (2226.2 kg ha-1
) was obtained from row spacing of 65 cm row spacing.
Similarly, more number of days to 50 % silking (63.6), higher ear weight at maturity (77.4 g), more number of
grains row-1
(339.4) and higher grain yield (2184.9 kg ha-1
) was recorded from nitrogen placement to both sides
of the row. All the interactions (RS×NP) were found non-significant for all the parameters. It is concluded that
maize preferably sown at 65 cm row spacing with nitrogen applied to both sides of the rows method to get
maximum yield.
