Uticaj NS Nitragina i zaoravanja žetvenih ostataka na morfološke osobine soje

Abstract

Zaoravanje žetvenih ostataka preduseva i primena mikrobiološkog preparata NS Nitragina imaju značajan uticaj na morfološke osobine biljaka soje. Zaoravanje žetvenih ostataka preduseva kukuruza povećava masu biljaka za 7,57%, povećava se broj fertilnih nodija 4,44%, broj mahuna po biljci 4,49% i broj zrna po biljci 6,25%. Primena NS Nitragina povećava masu biljaka 11,11%, broj fertilnih nodija 3,55%, broj mahuna po biljci 5,87% i broj zrna po biljci 6,30%. Na varijanti ogleda gde su zaoravani žetveni ostaci preduseva uz primenu NS Nitragina masa biljaka je povećana 18,79%, broj fertilnih nodija 6,26%, broj mahuna po biljci 7,59% i broj zrna po biljci 10,43%.

Ploughing in crop residues of previous crop and application of the microbiological preparation of NS Nitragin have significant effect on the morphological characteristics of soybean plants. Ploughing in, crop residues of first crop before maize increases the mass of plants by 7. 57%, the number of fertile nodes increases by 4. 44%, the number of pods per plant by 4. 49% and the number of grains per plant by 6. 25%. The use of NS Nitragin increases the mass of plants 11. 11%, the number of fertile nodes 3. 55%, the number of pods per plant 5. 87% and the number of grains per plant 6. 30%. On the variant, where the crop residues where ploughed down with the application of NS Nitragin, the mass of the plants increased 18. 79%, the number of fertile nodes 6. 26%, the number of pods per plant 7. 59% and the number of grains per plant 10. 43%.
