20.500.12556/DiRROS-25049 Effect of Nitrogen Topdressing on Seed Yield and Flour Protein Content in Semidwarf Common Buckwheat Vpliv dognojevanja z dušikom na pridelek semen in vsebnost beljakovin v moki polpritlikave navadne ajde This study evaluated the effects of nitrogen topdressing on the semidwarf common buckwheat (line ‘18-601’), focusing on growth, seed yield, and flour protein content. We conducted a field experiment and applied four nitrogen topdressing treatments at different growth stages: basal fertilization alone (2-0-0), basal fertilization plus nitrogen at flower bud appearance (2-2-0), basal fertilization plus nitrogen at full flowering (2-0-2), and basal fertilization plus nitrogen at both stages (2-2-2), using a randomized complete block design, with each plot measuring 1.2 × 2.5 m. Basal dressing was applied at 2, 8, and 4.7 g m-2 N, P2O5, and K2O, respectively. Nitrogen topdressing significantly increased chlorophyll content. The branch number, seed yield, number of seeds per square meter, and flour protein content tended to increase with nitrogen topdressing. The highest seed yield and protein content were observed in the 2-0-2 treatment, suggesting that nitrogen application at full flowering optimizes the yield and nutritional quality of semidwarf buckwheat. These findings highlight the importance of timing in nitrogen topdressing to enhance the agronomic and nutritional value of semidwarf common buckwheat.  V raziskavi so ocenjeni učinki dognojevanja z dušikom na polpritlikavo navadno ajdo (linija ‚18-601‘), pri čemer je raziskava osredotočena na rast, donos semen in vsebnost beljakovin v moki. Izvedli smo poljski poskus in uporabili štiri dognojevanja z dušikom v različnih fazah rasti: samo osnovno gnojenje (2-0-0), osnovno gnojenje z dušikom ob pojavu cvetnih popkov (2-2-0), osnovno gnojenje z dušikom ob polnem cvetenju (2-0-2) in osnovno gnojenje z dušikom na obeh stopnjah (2-2-2) z uporabo naključne zasnove blokov, pri čemer vsaka parcela meri 1,2 × 2,5 m. Osnovno gnojenje je bilo uporabljeno pri 2, 8 in 4,7 g m-2 N, P₂O5 oziroma K2O. Dodatek dušika je znatno povečal vsebnost klorofila. Število vej, pridelek semen, število semen na kvadratni meter in vsebnost beljakovin v moki so se povečali z dodatkom dušika. Najvišji pridelek semen in vsebnost beljakovin sta bili ugotovljeni pri obdelavi 2-0-2, kar kaže, da uporaba dušika pri polnem cvetenju optimizira pridelek in hranilno kakovost polpritlikave ajde. Te ugotovitve poudarjajo pomen časovnega usklajevanja pri dodajanju dušika za povečanje agronomske in hranilne vrednosti polpritlikve navadne ajde. true false true Angleški jezik Slovenski jezik Članek v reviji 2026-01-08 12:49:10 2026-01-08 12:49:10 2026-01-12 08:39:36 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 17. 10. 2024 str. 41-47 št. 2 letn. 41 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-06-03 633.12:581.14 2712-2859 10.3986/fag0040 211981315 https://ojs.sazu.si/fagopyrum/article/view/8052 0 c1100ad9-ed32-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37702 document-6.pdf document-6.pdf 1 97F8F109E63B46986A0031FAC768E95C c3da9c02bff8afb92dc536b618a1288c332ab8602f1fbdc344abdc9533e064d8 c764ca85-ec8e-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37609 Slovenska akademija znanosti in umetnosti Fagopyrum [Elektronski vir] 0 0 0
