Abstract: Experiments were conducted at different sites to evaluate the response
of wheat to foliar application of N and K under rainfed conditions of
potohar region of Punjab. These studies were conducted to compare the
effect of K (KNO3 and KCl) sources as foliar application
at different growth stages of wheat. The treatments were (1) Control
(No spray); (2) K 0.5% solution (as KNO3); (3) N & K
0.5% and 0.2 % solution (as KC+ Urea); (4) K @ 0.5% solution (as KCl);
(5) N @ 0.2 % solution as Urea. Biological yield of wheat improved significantly
with N and K application. The highest biological yield 10938 was obtained
by foliar application of KCl along with nitrogen. The response of foliar
potash application on Chakwal-86 wheat variety was significant among
the different treatments. This study proved that both sources of potash
i.e. KNO3 and KCl are equally effective in increasing wheat
yield and can be helpful in achieving maximum realizable yield. Nitrogen
application improved the N and K content in the leaf tissues and uptake
by plant which resulted in more production. Foliar application of potash
at critical stages can be helpful in barani areas of Pakistan
to realize optimum economic yield.
