Research was conducted in Poland in 2017–2019 at Siedlce University of Natural Sciences and Humanities in Siedlce. It aimed at determining the effect of the bacteria Bacillus megaterium var. phosphaticum, the amino acid L-alpha proline, and the mineral nitrogen fertiliser regime on iron content in soil during the period of rapid growth of spring wheat plants, as well as in spring wheat grain and straw. The following two factors were examined: (I) biological products: untreated control, Bacillus megaterium var. phosphaticum, L-alpha proline, Bacillus megaterium var. phosphaticum + L-alpha proline; (II) mineral nitrogen fertiliser regime: nonfertilised control, 60 kg Nּha−1, 90 kg Nּha−1, 90 kg Nּha−1 + foliar fertilisation. The study demonstrated that, during the period of rapid spring wheat plant growth, Fe content was the highest in the soil following an application of Bacillus megaterium var. phosphaticum + L-alpha proline + mineral nitrogen fertiliser applied at the rate of 90 kg Nּha−1. This combination resulted in the highest concentration and uptake of iron by spring wheat grain, whereas for straw, the same result was also achieved following mineral nitrogen fertiliser at a rate of 90 kg Nּha−1 + foliar fertilisation.

This paper analyses the effects of soil and foliar fertilization with sodium selenate (VI) on the selenium content in spring wheat grain. The research was carried out at the Departmental Experimental Station of the Institute of Agriculture WULS in Skierniewice in 2018 and 2019. The dose of selenium used was 5.00 g Se·ha−1 in various development stages of spring wheat. The results showed that selenium fertilisation did not affect the size of the grain yield, but both soil and foliar fertilisation significantly increased the content of selenium in wheat grain compared to the control group. The highest Se content was obtained with the method of soil fertilisation combined with the foliar application with a total dose of 10.00 g·ha-1 Se in the stem elongation phase (S + F2), and in the tillering and stem elongation phase (S + F1 + F2), which resulted in the values of 0.615 and 0.719 mg·kg−1 Se in grain, respectively. On this basis, it was concluded that the best time to carry out foliar fertilisation treatment is in the stem elongation phase (BBCH 30–39). The results show that the greatest increase in selenium content in the grain is achieved with soil and foliar fertilisation combined.

Abstract A field experiment was carried out at the second agricultural research and experiment station of the College of Agriculture, Muthanna University, for the 2019-2020 agricultural season, with the randomized complete block design RCBD, using two factors and three repeats, that’s to study the effect of adding the bio inoculant from Bacillus megaterium bacteria, and when loaded the bacterium with the immobilization inoculation technology on zeolite, sodium alginate, Agarose and bentonite and it’s symboled of M0, M1, M2 and M3 respectively to compare its efficiency in increasing potassium available and growth of wheat plant variety Eba’a 99. The experiment included two comparison treatments, the first being B0 without the addition of the bacterial inoculant and the second comparative treatment being B1 adding the bacterial vaccine. At the end of the experiment, potassium concentration was estimated in soil after cultivation. The results showed a clear moral effect of the use of the immobilized bacterial inoculant in Nitrogen available at a 15.65 (mg N kg−1 soil) and with an increase of 17.14%, Potassium available at a 289.2 (mg K kg−1 soil) and an increase of 6.79%, and the plant height was a rate of 84.87 cm and an increase of 9.41% and bio yield at 810.25 kg dunum−1 and an increase of 34.98%.

The paper presents the results of applying nitrogen fertilizers for spring wheat of the Novosibirsk 31 variety. The use of the fertilizers produced additional 1,62 t/ha of grain relative to the control variant. The maximum yield was 5,4 t/ha. The increased doses of the mineral fertilizers resulted in the increased ammonium ion in the grain, the rate reached 0,76 %. The excess of ammonium ion in spring wheat is neutralized by glutamine in the composition; the glutamine content reached 5,4 %. At the same time, the synthesis of arginine was reduced from 5,1 to 1,0 %.

Relevance and Methods. The effect of three doses of nitrogen fertilizers (N30, N60, and N90) on the formation of a crop of vetch seeds mixed with spring wheat was studied in a field experiment in sod-podzolic sandy loam soil.Results. In average for the study years, the yield of vetch seeds under the influence of nitrogen fertilizers decreased at the dose of mineral nitrogen 30 kg/ha by 12,7% at a dose of 60 kg/ha by 26,4% at a dose of 90 kg/ha by 36,4%, and grain yield of spring wheat increased, respectively, 1,8; 2,5 and 2,9 times. A significant decrease in the yield of vetch was observed at doses of mineral nitrogen N60 and N90, the yield of wheat grain significantly increased at all doses of mineral nitrogen. Nitrogen fertilizers were most effective in drought conditions, when the symbiotic fixation of air nitrogen in the crop area was weakened. Under conditions of increased moisture, nitrogen fertilizers did not provide an increase in the grain yield of the mixture, but increased the resistance of the crop to lodging, which made the mixture more technologically adapted to harvesting.

The EPIC and CERES simulation models were used to predict spring wheat (Triticum aestivum L.) grain yield from long-term (1960–1989) crop rotations at Melfort, Saskatchewan. Although both models simulated annual yields poorly, they predicted long-term mean yields with reasonable accuracy. Key words: Spring wheat, Triticum aestivum L., yield, models, CERES, EPIC

Li, X., Ziadi, N., Bélanger, G., Yuan, W., Liang, S., Xu, H. and Cai, Z. 2013. Wheat grain Cd concentration and uptake as affected by timing of fertilizer N application. Can. J. Soil Sci. 93: 219–222. The effect of a single N application (120 kg ha−1) at seeding on wheat (Triticum aestivum L.) grain Cd concentration and uptake was compared with an equally split N application (seeding and the stem elongation stage) in a field experiment at 12 site-years. Averaged across all site-years, the single N application tended to reduce wheat grain Cd concentration (58 vs. 68 µg kg−1DM) and uptake (151 vs. 191 mg ha−1) compared with the split application. The Cd concentrations, however, never exceeded the maximum acceptable level for Cd in wheat grain. A single N application at seeding might reduce the risk of high grain Cd concentration in spring wheat.

Protective Proteins

We studied the immunohistochemical localization of abscisic acid (ABA), wheat germ agglutinin (WGA) and dehydrins in the roots of wheat seedlings (Triticum aestivum L.) during 24-epibrassinolide-pretreatment (EB-pretreatment) and PEG-induced dehydration. It was found coimmunolocalization of ABA, WGA and dehydrins in the cells of central cylinder of basal part untreated and EB-pretreated roots of wheat seedlings under normal conditions and under osmotic stress. Such mutual localization ABA and protective proteins, WGA and dehydrins, indicates the possible effect of their distribution in the tissues of EB-pretreated wheat roots during dehydration on the apoplastic barrier functioning, which apparently contributes to decrease the water loss under dehydration. Perhaps, the significant localization of ABA and wheat lectin in the metaxylem region enhances EB-induced transport of ABA and WGA from roots to shoots under stress. It can be assumed that brassinosteroids can serve as intermediates in the realization of the protective effect of WGA and wheat dehydrins during water deficit.
