Abstract:
An experiment was
conducted according to randomized
complete design to determine best plant
spacing and agronomic traits at research
farm PMAS Arid Agriculture University
Research Farm Chakwal Road, Rawalpindi,
during 2008-2009. Three plant spacing’s
(5, 10, 15 cm) and three row spacing’s (10,
20, 30 cm) comprised of the following
treatment combinations (T1= 5×10 cm,
T2= 5×20 cm, T3= 5×30 cm, T4= 10×10
cm, T5= 10×20 cm, T6= 10×30 cm, T7=
15×10 cm, T8= 15×20 cm, T9=15×30 cm)
under rain-fed conditions. The net plot size
was 2×6 m with three replications. Days to
emergence, plant height at maturity, number
of branches per plant, number of capsules
per plant, number of seed per capsule, 1000-
seed weight, seed capsule ratio, seed yield
per plot, biological yield, harvest index, oil
concentration and fresh weight of weeds
was observed. All agronomic attributes were
significantly effected at 15×30 cm spacing,
along with oil concentration and fresh
weight of weeds, while 10×10 cm row to
row and plant to plant spacing had no
significant effect. Plant height (cm), number
of capsules per plant was maximum for
plant geometry of 15×30 cm and lesser
amount of weeds. An increase in row and
plant spacing led to significantly higher of
branching. Higher plant and row spacing
resulted in non- consistent increase in the
number of seeds per capsule. Seed yield
increased with higher row to row and plant
to plant spacings. Yield were lower at the
narrow (10×10 cm) row and plant spacing’s,
compared to higher of 15×30 cm spacing.
Thus, it is concluded from this study that
Linola should be grown at 300-450 cm grids
for higher yield output.
