Effect of soil applications of manganese, boron, zinc, copper and magnesium on the yield and compostion of potato tubersHarris, Robert Ernest January 1953 (has links)
Ah experiment was conducted to ascertain the effect of soil applications of manganese, boron, zinc, copper and magnesium on the yield and composition of potato tubers (variety Green Mountain).
The following determinations were made on the harvested crop: yield, percentages of dry weight, ash, carbohydrate, roughage, and nitrogen; and the minerals phosphorous, potassium, chlorine, calcium, manganese, copper and iron.
The significant findings were as follows: the boron treatments increased the yield of tubers and increased the copper content; the manganese and zinc treatments both reduced the calcium content and copper reduced the ash content of the tubers.
There were also marked trends in the following: the zinc treatments tended to increase yield and the nitrogen and magnesium content of the tubers; the copper treatment tended to increase the calcium content; the manganese treatment tended to depress the ash content and increase the chlorine content of the tubers; the magnesium treatment tended to decrease the chlorine and the copper content of the tubers.
The significant findings, as well as the definite trends of the effect of the treatments, are discussed.
As a result of this experiment, it is recommended that boron be included in the fertilizer treatments for potatoes grown on the type of soil, and under conditions similar to those of this experiment. / Science, Faculty of / Botany, Department of / Graduate
