[Yielding capacity and chemical content of corn plants under effect of potassium and zinc]
1993
Belyaev, G.N.
It has been found that zinc increased the yield of corn grown on a sandy soil with potassium deficit only under the complex application of both mentioned elements, high doses of the latter being more effective in the presence of zinc. The effect produced by zinc addition (0,6% of KCl weight) was near to the maximum. Application of zinc and potassium changed the content of some elements in plants.
