Aim: Eco-friendly and
sustainable weed management tactics are advocated by weed managers worldwide.
In order to develop such a technology, an experiment was undertaken at
Agronomic Research Area of the Faculty of Agriculture, Gomal University, Dera
Ismail Khan, Khyber Pakhtunkhwa province, Pakistan during rabi season.
2-factor experiment was laid out in a randomized complete block design with
split plot arrangement with the planting patterns (line and criss cross
sowings) assigned to main plots and seed rates (50, 100, 150, 200 kg ha-1)
of wheat kept into sub plots.
density and biomass at harvest were 28 and 33%, lesser in a criss cross as
compared to line sowing. Weed suppression was inversely and grain yield was
directly proportional to seeding rates. The highest grain yield (6.9 t ha-1)
was obtained from the interaction of 200 kg ha-1 seed rate under
criss cross planting.
Interpretation: Regardless of
planting pattern, 37% higher grain yield was harvested at the highest rate
(200 kg ha-1) as compared to the lowest (50 kg ha-1)
seed rate. Thus, integration of denser crop and uniform stand via criss cross
pattern planting in small grains can reduce the pollution of herbicides and
energy cost on weed management.
