Abstract:
An experiment was carried out to know the effect of irrigation, soil and
foliar application of zinc on the growth and yield contributing
characteristics of wheat. In this experiment, irrigation viz T

revealed that individual effect of irrigation was significant on all selected
parameters. The effect of zinc application was found significant while the
higher dose of foliar application of zinc increased the yield of wheat
compared with the application of zinc in soil. Results showed that the
highest number of grains per spike (48.20) was achieved from both T

revealed that foliar application of zinc was more effective than the
application in soil. In addition, skipping irrigation at flowering and
heading stage with foliar application of zinc (0.04%) could be
recommended for higher yield of wheat.
