Effects on Growing and Yield of Potatoes by Different Quantity of Fertilizer Application

doi:10.7668/hbnxb.2005.S1.037

Abstract

Abstract: Muneral elements as nitrogen,phosphorus.etc.in stems,leaves and tubers of potatoes are mainly assimilated and transferred to different organs from soil through root system;Parts of mineral elements in female tubers are transferred to new organs as well.The assimilation for nitrogen,phosphorus and potassium at different growing period is increased gradually from germination to tuber growing,with the fastest increase from baby plant to tuber formation,and reaching the highest at the tuber increasing period.Under this experimental condition,when fertilizer and intensity are in proper condition,the effect on potato yield by tested elements is in the following order:K fertilizerN fertilizerP fertilizer.

Key words: Potato, Quantity of fertilizer application
