CONTENT OF BIOGENIC ELEMENTS INDUCTED BY THE INFLUENCE OF THE INOCULANT IN SELECTED CHICKPEA SLOVAK VARIETIES

Abstract

In the study, we focused on the evaluation of the content of biogenic elements inducted by the addition of inoculant in six Slovak chickpea varieties. We analyzed Cu, Zn, Mn, Fe, Cr, Ni, Co, K, Na, Ca, Mg and P. We evaluated two variants from each variety control variant (A) and variant with inoculant (B). Seed inoculation was provided by the inoculant Rizobin. We used for analyzed 1 g from dry seeds from each genotype. We mineralized the samples on a MARS X-press. The result was atomic absorption spectrometry using VARIAN DUO 240FS / 240Z.

The average Cu content in A control variant was 5.95 mg.kg^-1 was reduced to 5.53 mg.kg^-1 by the addition of inoculant. For Zn, we also recorded a reduction by the addition of inoculant from 25.43 mg.kg^-1 of variant A to 24.95 mg.kg^-1 of B variant. The Mn content was the same in both variants and did not change significantly. We recorded the largest differences in the Fe content. The Fe content was reduced from 50.60 mg.kg-1 variant A to 45.07 mg.kg-1 variant B by adding an inoculant. The content of Cr, Ni and Co did not change significantly with the addition of inoculant. Potassium ranged from 8904.45 mg.kg^-1 variant A to 8720 mg.kg^-1 B variant. Variant A had detected a higher Na content 84.22 mg.kg-¹. The average content of Ca and Mg was reduced by adding the inoculant of B variant. The P content of 1400.88 mg.kg-1variant B was reduced in variant A to 1346.53 mg.kg-¹.
