This study showed the effect of different methods of application of mineral fertiliser rates on the yield of two potato cultivars grown under the agroenvironmental conditions of the Radočelo Mountain massif on a luvisol exhibiting rather favourable agrophysical and some what poorer agrochemical properties. In 2018 and 2019, a trial with potato cvs. ‘Arizona’ and ‘Esmee’ was established. Planned rates of mineral fertilisers (N200, P150, K150) were applied as two treatments: treatment 1 – fertiliser rates were ploughed in during autumn, and treatment 2 – one half of the planned rates was applied during seedbed preparation and the other half in-furrow at planting. The results showed that the treatment involving the application of one half of the fertiliser rate before planting, and the other half at planting resulted in higher total yields of both potato cultivars compared with the placement of the whole rate of fertilisers during deep ploughing in autumn.
