Abstract

Soja (Glycine max (L.) Merr.) je v svetu najbolj razširjena in gospodarsko pomembna zrnata stročnica. Kot beljakovinsko krmilo je uporabna v živinoreji, kot oljnica za pridobivanje olja. V času rasti in razvoja kopiči v gomoljčkih na koreninah dušik iz zraka, ki ga vežejo nitrifikacijske bakterije Rhizobium japonicum in Bradyrhizobium japonicum. Raziskava obravnava pridelek in kakovostne parametre zrnja soje v povezavi z zeolitom in inokulacijo. Zeolit je kamnina vulkanskega izvora, ki je sestavljena iz silicija, aluminija in kisika. V kmetijstvu ga uporabljamo predvsem zaradi dobre izmenjalne kapacitete N, K, Ca in Mg ionov ter zaradi vezave ionov težkih kovin, da niso dostopne rastlinam. V poljskem poskusu na Biotehniški fakulteti v Ljubljani smo uporabili sorto 'NS Favorit' in seme inokulirali s svežim inokulantom 'Nitragin'. Ugotovili smo, da inokulacija semena pomembno vpliva na razvoj števila nodulov, na nekatere morfološke lastnosti in pridelek, vendar pa inokulacija ni pogoj za nastanek samih nodulov. Največji pridelek 5328 kg/ha pri 9-odstotni vlažnosti je doseglo obravnavanje z uporabo inokuliranega semena soje pri dodatku 5000 kg/ha zeolita v tla. Razlika med inokuliranimi in neinokuliranimi semeni je pokazala 40,4-odstotno razliko v velikosti pridelka zrnja v korist inokuliranega semena. Potrdili smo tudi vpliv inokulacije na večji delež surovih beljakovin v zrnju. Dodatek zeolita pa prav tako prispeva k večjemu deležu surovih beljakovin, pri čemer pa je manjši delež surovih maščob. Na vsebnost surovih vlaknin in pepela inokulacija in zeolit nista pomembno vplivala.

Secondary title: Seed yield and quality characteristics of soybean (Glycine max (L.) Merr.) in relation to zeolite and bacterial inoculation
Secondary abstract: Soya (Glycine max (L.) Merr.) is the most widespread and economically important legume in the world. Used as a protein animal feed it is used in livestock farming, oil and fibre production. In time of growth and development it stores nitrogen from the air in tubers on it’s roots, it gets the nitrogen from help of the Nitrifying bacteria Rhizobium japonicum and Bradyrhizobium japonicum. The research discusses yield and quality parameters of the soy seeds in connection of zeolites and inoculation. Zeolite is a stoneware of volcanic origin, which is formed from silicon, aluminium and oxygen. We use it in farming mostly for it’s good exchanging capacity of N, K, Ca and Mg ions, and for their inflection of ions and heavy metals, so that they are inaccessible to plants. In field tests at the Biotehnical Faculty of Ljubljana we used the“NS Favorit” species and we inoculated the seed with fresh “Nitragin” inoculant. We realized that inoculation of seed greatly affects the development of number of nodules. The biggest yield of 5328kg/ha at 9-percent humidity reached treatment with the use of inoculated seed of soy with added 5000kg/ha zeolite to the ground. The difference between inoculated and un-inoculated seed shown us a 40,4-percent difference in yield size of the seed. We have certified the effect of inoculation on the bigger part of raw protein in the grain. The additive of zeolite ministrates to a bigger share of raw protein, in which there is a smaller share of raw fat. On the content of raw fiber and ash inoculation and zeolite did not hold an important effect.
