Efficiency of celeriac fertilization with phosphorus and potassium under conditions of integrated plant production

Marcin Niemiec [et al.] - Nama Orang;

The goal of this work was to assess the efficiency of celeriac fertilization with phosphorus and potassium under conditions of integrated plant production. The goal was realized by performing a strict experiment.Celeriac (Diamant cultivar) was the test plant. A controlled-release fertilizer, with NPK content of 18%, 5% and 11%, was used for fertilization. Moreover, the following conventional fertilizers were used: ammonium nitrate, granular triple superphosphate, and potassium salt. The efficiency of the fertilization was evaluated by calculating the following indices: agronomic effectiveness, productivity coefficient and removal efficiency. The most favourable productivity coefficient and agronomic effectiveness were reached when 300 and 400 kg of the slow-acting fertilizer was used along with additional fertilization with ammonium nitrate, and this variant of fertilization under conditions of conducting the experiment would be optimal. In the conventionally fertilized treatments, values of these parameters were several times lower. That is why measures that improve the efficiency of production may bring positive results. Results of the conducted research indicate that optimization of fertilization under conditions of intensive production may significantly increase the efficiency of production.

Keywords:integrated production; the effectivensess of fertilization; phosphorus; potassium; sustainable fertilization; slow-acting fertilizer;celeriac.
