Effect of localities and organic fertilizers on yield in conditions of organic farming

Popis výsledku v původním jazyce

Nitrogen fertilization cannot be used by actual needs of plants during vegetation in organic farming. The proper crop rotation and harmonic nutrition are necessary for good and quality products. The methods of treatment are mainly realized by cultivation of green manure crop and fertilizing by organic fertilizers. The aim of the long-term experiment was to evaluate the effect of different localities and different organic fertilizers on crop yield in organic farming. Variants of fertilization included in the experiment are: 1. Unfertilized control, 2. Green manure, 3. Green manure+renewable external sources, 4. Green manure+renewable external sources+auxiliary substances, 5. Green manure+farm fertilizers, 6. Green manure+farm fertilizers+auxiliary substances. The experiment started by sowing of winter wheat so green manure crop was not grown in the first experimental year. The highest yield of winter wheat grain coming from the first year of the experiment was observed on the variant with renewable external sources (digestate). Average grain yield on this variant was about 7.12 t/ha (up to 0.74 t/ha increased than the unfertilized control). Average yield of potatoes from the second year of the experiment was the highest after combination with green manure+renewable external sources (compost+digestate)+auxiliary substances. This variant achieved yield about 34.08 t/ha, which is increased by 9.35 t/ha compared to the control variant. Results from this two-year experiment showed that the most suitable combination of fertilization with or without green manure crop is compost+digestate. These results were probably caused by higher content of nitrogen in organic fertilizers (compost+digestate) used in this variant compared to other variants. Statistical difference of achieved yields was observed between each experimental station in both experimental years.
