Pre-sowing treatments were S1: no pre-sowing treat-ment (intact seeds), S2: hydro-priming, S3: bio-priming (seed inoculation with plant promoting rhizobacteria consortium: Azotobacter chroococcum + Azospirillum lipoferum), S4: mi-cronutrient seed priming and foliar feeding include, check (0): distilled water spray, Fe: foliar spray of iron, Zn: foliar spray of zinc. All seed priming treatments significantly increased plant height, tiller number, canopy width, total biomass, spike mass, seed number per spike and seed yield compared to intact seeds. A brief comparison of the effect of seed priming and fertilizer treatments showed that the effects of priming treatments on im-proving growth and seed yield was more obvious than fertilizer treatments. The greatest increase in seed yield and yield com-ponents was recorded for plants grown from bio-fortified seeds by essential trace elements. However, comparison of fertilizer treatments showed that growth parameters were significantly affected by Zn application. From the present study, it may be concluded that combined seed priming through pre-sowing hy-dration, soaking in micronutrients and microbial inoculation is useful to enhance wheat production and agricultural sustain-ability for smallholder farmers in semi-arid regionRaziskava je bila izvedena za ovrednotenje učin-kov predtretiranja semen in foliarnega nanosa mikroelementov na uspevanje krušne pšenice v polsušnih območjih severoza-hodnega Irana. Predsetvena obravnavanja semena so bila: S1- brez obravnavanj (intaktna semena), S2 - predtretiranja z vodo (hydro-priming), S3 - bio-priming (semena inokulirana z me-šanico bakterij, ki promovirajo rast rastlin - Azotobacter chroo-coccum + Azospirillum lipoferum), S4 - semena predtretirana z mikrohranili in kasnejšim foliarnim dodajanjem mikrohranil, kontrola (0): pršenje listov z distilirano vodo, Fe: foliarno pr-šenje z železom, Zn: foliarno pršenje s cinkom. Vsa predtre-tiranja so značilno povečala višino rastlin, število stranskih pogankov, širino krošnje (nadzemnega dela rastlin), celoku-pne biomase, maso klasov, število semen na klas in pridelek semena v primerjavi z intaktnimi semeni. Primerjava učinkov predtretiranja semen in obravnavanj z gnojili je pokazala, da so bili učinki predtretiranj semen na povečanje rasti in pridelka bolj očitni kot učinki gnojenja. Največje povečanje pridelka semen in njegovih komponent je bilo zabeleženo pri rastlinah, ki so zrasle iz semen predtretiranih z mešanico bakterij in esencielnih hranil v sledeh. Primerjava obravnavanj z gnojili je pokazala, da je bilo povečanje rastnih parametrov značilno boljše pri uporabi Zn. Iz te raziskave bi lahko zaključili, da bi bila kombinacija obravnavanja semen s predsetvenim tretira-njem z vodo, namakanjem semen v raztopini mikrohranil in inokulacijo z mikrobi koristna za povečanje pridelave pšenice in trajnosti pridelave pri manjših kmetih v polsušnih območjihTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
