Abstract

 SIGNIFICANT positive influences of fertilization with ⅔ of the …...recommended mineral-N dose + inoculation three times with a mixed bio-fertilizer (Azotobacter chroococcum + Azospirillium brasilense) were observed on growth traits, fruits yield and leaf N, P, K, NO3- and NO2– contents of pumpkin plants compared to fertilization with ⅔ of the recommended mineral-N dos+ inoculation once or twice with the same mixed bio-fertilizer. However, no statistical differences in the aforementioned parameters were noted between fertilization with ⅔ of the recommended mineral-N dose + inoculation three times with a mixed bio-fertilizer and addition of whole recommended dose of mineral-N (control). The least significant mean values of leaf NO3- and NO2– content were attained at fertilization with ⅔ of the recommended mineral-N dose + inoculation three times with a mixed bio-fertilizer. Therefore, inoculation with a mixed bio-fertilizer three times can substitute partially of mineral-N fertilizer and contribute to safety food.
