The present investigation was carried out during 1990/91 and
199 1/92 seasons on clay soil in the Research and Experiment Center,
Faculty of Agriculture at Moshtohor to study the effect of foliar
application of urea alone or in combination with Zn, Mn and Fe on
wheat yield attributes and nutrient content of wheat grains. ,
The results i,idicated that : plant height, number of spikes/ni2 .
spike length, number of spikelets/spike, IOOU-grain weight, grain and
straw yieids/feddan as well as protein percentage and protein yield per
feddan were significantly increased by spraying urea alone or with
the dij’ferent of micronutrients at booting stage as compared the
control treatment. On the
other hand, foliar application treatments had no significant effect on
number of grains/spike, spike weight and grain weight/spike. The
highest grain and straw yields/fed. were obtained by spraying urea
with Zn + Mn + Fe, but without significant differences with the urea
alone treatment. Foliar application of urea alone or with Zn or with
Fe gave the maxinium protein content and protein yield/fed. N, Zn.
Mn, Fe uptake by wheat grains were signijicantly increased bvfo/iar
application of urea or Zn or Mn or Fe or both of theni as compai’ed
with the control treatment.
