Nitrogen Fixing Bacteria

The aim of this study was to examine the possibilities of reducing the mineral nitrogen fertilizers by applying the free‐living (Azotobacter chroococcum) and associative (Azospirillum brasilense) nitrifying bacteria in the sugar beet production, without a reduction in the yield and quality of the sugar beet root. Along with the vegetables, most nitrates are collected by the species of the family Chenopodiaceae, to which the sugar beet belongs. Nitrogen is one of the most vital elements in the achievement of high yields, so it is used in large quantities in fertilization. However, it is the most unstable macroelement that flushes into the deeper soil layers, and a groundwater eutrophication is caused very often. Numerous diseases are associated with the high amounts of nitrates, nitrites, and nitroso compounds, i.e., the nitrite and nitroso compounds originating from the foodstuffs having a plant origin, water, and the cured meat products. The results of the study have demonstrated that it is possible to reduce a mineral nitrogen fertilizer quantity by using the nitrogen‐fixing bacteria while even obtaining a higher quality of the studied parameters. The nitrogen‐fixing bacteria predominate in the rhizosphere, so the plants could use the amounts of nitrogen necessary in a given vegetation period, which is not the case upon a nitrogen fertilization.

Gas Chromatographic Method

Numerous articles on Salvia officinalis L. have been published regarding the composition of their essential oil. The considerable variation found may be due to the quality of the plant material as well as to the methods used for analysis. A simple GC-MS method was developed and optimized in the QbD approach, for the determination of sage essential oils. The optimization of GC-MS analysis was performed using different mobile phase flows, injection volumes, split ratios and temperature programs. The optimized method proved to be simple and can be successfully applied for the determination of sage essential oils.

Environmental contamination and the excessive use of inorganic fertilizers resulting in stagnant yields of field crops which necessitate the utilization of combined fertilization approach under changing climatic conditions. Current study was aimed to clarify the influence of several fertilizer sources (chemical, organic, organomineral fertilizers) on yield and quality of coriander (Coriandrum sativum L.). The results revealed that the fertilizer sources significantly affected the yield of coriander cultivars. The absence of “Year x Variety x Fertilizer Type” interactions for any of the noted parameters signaled that the detected “Variety x Fertilizer Type” interactions were constant regardless of the year factor. The recorded values of traits according to fertilizer sources different for the plant height from 61.85 to 69.67 cm, number of branches from 5.98 to 7.71 (piece/plant), number of umbels per the main umbel from 5.62 to 7.18 pieces, seed yield from 1.06 to 1.66 t/ha, the biological yield from 4.29 to 5.70 t ha−1, harvest index from 25.29 to 29.41%, essential oil ratio from 0.29 to 0.33%, and essential oil yield from 3.1 to 5.6 L ha−1. Erbaa variety was observed to be superior over the rest of the varieties producing the maximum values of 6.5 L ha−1 of essential oil, 0.36% essential oil content, 30.9% harvest index, 1.81 t/ha seed yield, and 5.9 t ha−1 biological yield with the treatment of chemical fertilizers.
