Soil and foliar applications of nutrients affect potato yields, dry matter, and foliar necrosis

  • Winston M. Laughlin
Article

Summary

A series of field experiments from 1958 through 1960 was conducted to determine the effect upon potato leaf breakdown and tuber yields of nitrogen, lime and soil and spray applications of KCl, K2SO4 and other sprays.

Lime had no significant influence on foliar breakdown or tuber yields.

Increasing nitrogen levels increased foliar breakdown and US No. 1 tuber yields.

Soil and spray potassium applications, irrespective of potassium source, decreased foliar breakdown and increased US No. 1 tuber yields. Spray application of K was not as effective as soil application in reducing foliage breakdown.

Tuber dry matter content was reduced consistently by KCl applied to the soil or as a spray. In 1958 K2SO4 increased the dry matter content, but did not influence it significantly in other years. Sodium phosphate sprays increased tuber dry matter content in 1958.

Soil applications of potassium in 1960 increased the potassium content of the tubers, soil application of KCl tended to decrease the phosphorus content whereas spray applications of potassium had no significant influence on the phosphorus content.
