THE EFFECT OF BASIC NPK FERTILIZATION AND SOME NITROGEN FORMS APPLIED TO POTATO AND SUGAR BEET CROPS AFTER PLANTING
Abstract
The identification of complex fertilizer assortments and the development of differentiated methods of application of nitrogen fertilizers to potato and sugar beet crops are major objectives of fertilization technologies, in order to reach the maximum production potential in terms of quantity and quality. Nine variants of fertilization recipes have been experimented with NPK complexes in 2014 and 2015 that included three NPK complexes for basic fertilization, at soil preparation before planting/sowing and fertilizers with various forms of nitrogen for phaseal fertilization applied to potato and sugar beet. The effect of basic NPK fertilization and some forms of nitrogen applied after planting the crops has been studied on the Christian potato variety and Clementina sugar beet variety. The experimental data recorded in 2014-2015 show that all fertilizer recipes tested on potato and sugar beet respond with production increases.
