Abstrakt
Grain yield of wheat is primarily limited by water stress. Therefore, to increase
productivity under drought conditions, a pot experiment was carried out at Maru Agricultural
Research Station (MARS), Jordan, during the year 2021 to investigate the effect of foliar fertilizer
by boron and magnesium under drought at either tillering or anthesis stages on some
physiological parameters and yield components of two varieties of durum wheat. Foliar
application by combined boron and magnesium had significantly improved the transpiration rate
and relative water content (RWC) of wheat varieties at both tillering (4.39 µg cm-2
s-1 and 82.55%,
respectively) and anthesis (7.43 µg cm-2
s-1 and 77.28%, respectively) growth stages, when
compared with controls at tillering (3.56 µg cm-2
s-1 and 76.63%, respectively) and anthesis
(5.79 µg cm-2
s-1 and 66.21%, respectively). RWC was significantly the highest by foliar boron
(79.4%) at tillering stage under drought. Meanwhile, total chlorophyll content by SPAD was
significantly the highest by combined boron and magnesium (46.8) during anthesis stage under
drought. In general, the results indicated that var. Maru 1 had significantly higher grain yield
(20.1 g/ plant) than var. Hourani (12.1 g/plant) may be due to differences in genetic makeup.
Foliar application by combined boron and magnesium significantly increased wheat varieties'
grain weight at tillering (18.2 g/plant) and anthesis (8.7 g/ plant) drought when compared with
controls at either tillering (13.7 g/plant) or anthesis (5.5 g/plant) drought. However, foliar
application did not significantly improve the grain weight under well-watered conditions. Our
findings showed that the foliar application is more important at antheis drought than at tillering
for increasing grain yield of wheat by improving of some physiological parameters.
