| Title : | THE EFFICIENCY OF USING NON-TRADITIONAL FERTILIZERS FOR WINTER OILSEED RAPE CROPS |
| Abstract : | Biogas plants and solid fuel boilers where wood ash and digestate are produced as by-products are widely used for energy and heat production. In agriculture, both wood ash and biomass digestate are used separately as liming and fertiliser materials, Field trials were conducted at the Study and Research Farm “Peterlauki” in sod calcareous soil. Winter oilseed rape sowings were established using different variants of fertilizer mix with cattle manure digestate (D) and wood ash (P) at different ratios: B1 – D; B2 – D + P 1:1; B3 – D + P 2:1; B4 – D + P 3:1; B5 – D + P 3:1 + N16P40K60 kg ha-1; B6 – D + P 3: 1 + N 68.8 kg ha-1; B7 – D + P 4: 1. The norms of the innovative mixed fertilizer from cattle manure digestate and wood ash were: A1 – 5 t ha-1, A2 – 10 t ha-1, and A3 – 20 t ha-1. Unfertilized winter oilseed rape fields and cattle manure digestate (D) fertilizer rates were used as control options. Studies have shown that using wood ash and digestate mixtures, it is possible to obtain good winter rapeseed yields without the use of mineral fertilizers. The highest winter rapeseed yield in the particular experimental year was obtained from variants where fertilizer rates of 10 t ha-1 were used for fertilization. |
