Placement of fertilizer for potatoes

Abstract

In twenty-nine experiments conducted in 1945, 1946 and 1947 placement of fertilizer in contact with the seed or in two bands each 2 in. away and 2 in. below the level of the seed gave average yields similar to those given by the standard practice of broadcasting after ridging but before planting. Placement in one band 2 in. below the seed was tested in four experiments and proved inferior to other placement methods and to broadcasting over the ridges.
