An experiment was conducted during 2009-10 and 2010-11 at research farm of division of
Agronomy, IARI, New Delhi, to study the effect of various doses and methods of zinc
application on maize and wheat. The treatment consisted of control, 12.5 kg ZnSO4 ha-1,
25 kg ZnSO4 ha-1 and foliar spray of 0.5 % ZnSO4 and two wheat Varieties ‘DBW 17’ and
‘PBW 343’. The grain, stover and biological yield of maize were significantly influenced
by application of zinc during first year and the maximum yields were recorded with the
application of 25 kg ZnSO4 ha-1 during both the year. During first year application of 25 kg
ZnSO4, 12.5 ZnSO4 ha-1 and foliar spray of 0.5 % ZnSO4 increased grain yield by 22.81,
18.63 and 8.36 percent respectively over control, while 4.10, 2.41 and 1.69% increase in
grain yield was recorded during second year. In wheat, application of 25 kg ZnSO4 ha-1
significantly increased 1000 grain weight during both the years while during second year
effective tiller m-2, grain spike-1 and grain diameter; as compared to the remaining
treatment. This treatment increased the number of effective tillers by 6, 10 and 11 percent
over the application of 12.5 kg ZnSO4 ha-1, foliar spray and control, respectively, during
second year. Direct application of zinc to wheat varieties i.e. ‘DBW 17’ and ‘PBW 343’
showed significant variation in grain, straw and biological yield and harvest index during
both the years. The yield advantage of 0.35, 0.26 and 0.28 and 0.43, 0.13 and 0.29 t ha-1
was recorded with the application of 25 kg ZnSO4 ha-1 over control, 12.5 kg ZnSO4 ha-1
and foliar spray, respectively. Highest straw and total biological yields were obtained with
the application of 25 kg ZnSO4 ha-1.
