YIELD OF WHEAT IN PSEUDOGLEY IN DEPENDENCE OF FERTILISATION WITH MINERAL FERTILISERS, LIME FERTILISER AND MANURE

The goal of this paper was to investigate the effect of numerous combinations of mineral, lime and manure fertilisers on wheat yield of two varieties (Pobeda and Kruna) grown on pseudogley. As mineral feeds NPK fertilisers were used, as lime fertiliser CaCO_3, and manure as organic fertiliser. Results of the investigation didn’t show statistical significance in grain yield at any of investigated variants of wheat, no matter what variant of fertilisation was used. With the use of mineral fertilisers, yield was rising from the lowest to the highest dose. Using the combination of mineral and lime fertilisers, especially those with higher doses of mineral feeds, higher yield was achieved which was statistically significant compared with those achieved only with mineral fertilisers. Combination of a manure, mineral and lime fertilisers gave a bigger yield, which was statistically very significant, than using of only mineral fertilisers. Also, using of that combination, but with increased dose of mineral feeds, gave a bigger yield than a combination of mineral and lime fertilisers, on a statistically very significant level. The biggest yield (5120 kg ha^-1) gave variety Pobeda with using of combination of manure, mineral (with higher dose) and lime fertilisers. The lowest yield (2810 kg ha^-1) gave variety Kruna with using of the lowest dose of mineral fertiliser.
