Description Not Available
A field experiment was conducted for 3 years to
evaluate the effect of deficit irrigation under different soil
management practices on biomass production, grain yield,
yield components and water productivity of spring wheat
(TriticumestivumL.). Soil management practices consisted of
tillage (conventional and deep tillage) and Farmyard manure
(0 and 10 t ha-1 FYM). Line source sprinkler laterals were
used to generate one full- (ETm) and four deficit irrigation
treatments that were 88, 75, 62 and 46 % of ETm, and
designated as ETd1, ETd2, ETd3, and ETd4. Deep tillage
significantly enhanced grain yield (14–18 %) and water productivity
(1.27–1.34 kg m-3) over conventional tillage.
Similarly, application of FYM at 10 t ha-1 significantly
improved grain yield (10–13 %) and water productivity
(1.25–1.31 kg m-3) in comparisonwith no FYM.Grain yield
response to irrigation varied significantly (5,281–2,704
kg ha-1) due to differences in soil water contents. Water
productivity varied from 1.05 to 1.34 kg m-3, among the
treatments in 3 years. The interactive effect of irrigation
9 tillage practices and irrigation 9 FYM on grain yield
was significant. Yield performance proved that deficit irrigation
(ETd2) subjected to 75 % soil water deficit had the
smallest yield decline with significant water saving would be
the most appropriate irrigation level for wheat production in
arid regions.
