Some effects of irrigation and pertilization on the yield and quality of Kennebec potatoes

Abstract

The data from this limited experiment show the following: (1) Irrigation may increase total yields of potatoes during dry years but may not always proportionately increase the yield of U. S. No. 1 potatoes. (2) Irrigationper se may lower the specific gravity of potatoes, but probably not enough to seriously affect marketability. (3) Fertilizers high in chlorides tend to lower the specific gravity of potatoes. (4) The equivalent of two per cent magnesium oxide in a water-soluble form in the fertilizer is needed to maintain an adequate level of magnesium in the soil assuming that 1500 to 2000 lbs. of fertilizer are used. (5) Substantial net migration of potassium, calcium, and magnesium from the fertilizer band to the surrounding soil in the potato hill did not take place during the growing season.
