Abstract
U vinogradarstvu, gnojidbu provodimo radi povećanja prinosa i kvalitete grožđa. Suvišan unos hranjivih tvari, jednako kao i njihov manjak, rezultiraju neuravnoteženim rastom biljke i razvojem lista. Vinova loza usvaja kalij u velikom postotku, čak do 60%. Cilj ovog istraživanja bio je utvrditi utjecaj organske i mineralne gnojidbe na količinu kalija u tlu i listu vinove loze (Vitis vinifera L.). U istraživanje je bilo uključeno šest varijanti gnojidbe (kontrola-bez gnojidbe, 20 t ha-1 zrelog stajskog gnoja, 40 t ha-1 zrelog stajskog gnoja, 20 000 L ha-1 kiselog treseta, 40 000 L ha-1 kiselog treseta i 500 kg ha-1 NPK 5-20-30 + 200 kg ha-1 UREE). Uzorkovanje lišća provedeno je tri puta tijekom vegetacije (cvatnja, dva tjedna nakon cvatnje i šara). Statistički značajno najveća vrijednost kalija, s godišnjim prosječnim vrijednostima, utvrđena je u drugoj godini istraživanja na tretmanima gnojidbe s 40 t ha-1 stajskog gnoja (0,40% K u ST) i 40 000 L ha-1 kiselog treseta.
Abstract (english)
In viticulture, we use fertilizing to increase the yield and quality of the grapes. Excessive intake of nutrients, or a lack thereof, leads to imbalance in plant growth and leaf development. Grapevine uptake potassium in a large percentage, even up to 60%. The objective of this study was to determine the effects of mineral and organic fertilization on potassium levels in soil and grapevine leaves (Vitis vinifera L.) In the survey included 6 treatments (unfertilized, farmyard manure 20 t ha-1 and 40 t ha-1, peat 20 000 L ha-1 and 40 000 L ha-1, 500 kg ha-1NPK 5-20-30 + 200 kg ha-1 UREA) in 4 repetitions. Leaves sampling was carried out three times during the vegetation (flowering, two weeks after flowering and veraison). Significantly the highest level of potassium, by annual average values, was found in second year of the study in fertilization treatments with 40 t ha-1 of farmyard manure (0.40% K/DW) and 40 000 L ha-1 acidic peat.
