The selection of appropriate sowing methods is very important for improving water
use efficiency. A field trial was conducted in the winter season of 2018-19 to
investigate the impact of different sowing methods on the water use efficiency of
spring wheat exposed to water deficit at anthesis. Wheat was sown with three
different sowing methods viz. broadcast sowing, drill sowing and augmented furrow
sowing and two different irrigation regimes i.e., normal irrigation and water deficit
at anthesis stage. All agronomic practices were kept uniform throughout the
experimental duration. Different sowing methods and irrigation regimes
significantly affected the grain and straw yield of wheat. Among different sowing
methods, the wheat crop was sown with augmented furrow method substantially
produced maximum plant height (111 cm), no. of tillers per m
2
(427), 1000 grain
weight (37.93 g), grain yield (4.73 t ha
-1
) and straw yield (4.24 t ha
-1
). Whereas,
statistically maximum irrigation water use efficiency (17.72 kg ha
-1
mm
-1
) and
benefit-cost ratio (1.34) was recorded in the augmented furrow method of sowing of
wheat exposed to water deficit at the anthesis stage. Farmers can sow wheat by
using the augmented furrow method to improve grain yield and irrigation water use
efficiency under water deficit at anthesis as compared to conventionally used drill
and broadcast sowing methods.

INTRODUCTION
Wheat is the leading cereal crop and staple food of the
majority of the population of Pakistan. Although,
Pakistan is the 8
th
largest wheat producer in the world
the country’s wheat productivity is less than that of
other countries in the region like China, India and
Bangladesh (Ahmad et al., 2021). Water use efficiency is
becoming a serious concern for agriculture particularly
in arid and semi-arid areas (Bhattacharya, 2019). The
scarcity of water is further aggravating the situation in
these areas by threatening crop productivity (Qasim et
al., 2019). Food shortage is a major issue in many
regions of the world including Asia and Africa (Aziz et al.,
2015). Improving irrigation water use efficiency under
the current scenario is becoming a serious global food
security concern. Wheat is the leading cereal crop
around the globe which is severely affected by different
abiotic stresses (Bali and Sidhu, 2019). Water deficit is
most destructive in terms of decreasing overall crop
yield as compared to any other kind of stress like
extreme temperature, cold and salinity (Noorka and
Heslop-Harrison, 2014). Shortage of water not only
