The aim of the study was to researched the influence of vermicompost, mineral and foliar fertilizer on the technological and chemical qualities of triticale varieties, which are characterized by both high productive potential and relatively high yield stability. In the Field Crops Institute ‒ Chirpan, Bulgaria, two trials were carried out in the period 2015-2017 in a conventional and biological field. The application of different rates of vermicompost, mineral and foliar fertilizer were tested on the parameters test weight, thousand kernel weight, protein and lysine in Bulgarian triticale varieties. The vermicompost was applied at the rates of 1400 and 1750 kg/ha, the mineral fertilization at the rates of N60P60, N120P60 and N180P60, and the same rates of mineral fertilizer+foliar fertilizer in two phases was applied in the combined fertilization. The results of the conducted study show that the studied triticale varieties show responsiveness to organic, mineral and foliar fertilization. Under the influence of N180P60 in combination with foliar fertilizer Lactofol O, the greatest increase in the values of the studied traits was observed, respectively: test weight - 75.5 kg/hl (Boomerang variety); thousand kernel weight – 48.3 g (Boomerang variety); protein content – 143.2 g/kg (Respect variety) and lysine content in the protein – 3.209 g/100g protein (Respect variety). A complex effect between the factors was not found. The strongest correlation was observed between protein and lysine content (r=0.999). [ABSTRACT FROM AUTHOR] |
