Phosphorus supply level is more important than wheat variety in safe utilization of cadmium-contaminated calcareous soil

Wheat production is a determining branch within Hungarian crop production (near 1 million hectares). Weather anomalies caused by climatic change confirmed the importance of biological basis (variety, hybrid) in wheat production. The adapting ability and reaction of different wheat genotypes towards nutrient supply were studied in a long-term field experiment on chernozem soil type in case of different pre-crops (sweet corn, sunflower and maize). According to the experimental results of the vegetation 2017/2018 the most highest yield amount of the variety Ingenio sown after the pre-crop sunflower ranged between 2710 kg ha-1 and 8710 kg ha-1, while the hybrid (Hyland) in case of the pre-crop sweet maize between 6556 kg ha-1 and 9270 kg ha-1 depending on the applied nutrient supply level. The studied genotypes showed the highest quality (protein, gluten) in case of the pre-crop sweet maize. In the cropyear of 2017/2018, the protein content of Ingenio ranged between 12.2-14.8%, while the Hyland in case of the pre-crops sweet corn between 9.9-13.9%. The gluten content of the Ingenio genotype changed between 24.9-32.5%, in the case of Hyland ranged between 16.9-27.3% in the studied cropyear.

Grain Zn Concentration

Human zinc (Zn) deficiency is a worldwide problem, especially in developing countries due to the prevalence of cereals in the diet. Among different alleviation strategies, genetic Zn biofortification is considered a sustainable approach. However, it may depend on Zn availability from soils. We grew Zincol-16 (genetically-Zn-biofortified wheat) and Faisalabad-08 (widely grown standard wheat) in pots with (8 mg kg−1) or without Zn application. The cultivars were grown in a low-Zn calcareous soil. The grain yield of both cultivars was significantly (P≤0.05) increased with that without Zn application. As compared to Faisalabad-08, Zincol-16 had 23 and 41% more grain Zn concentration respectively at control and applied rate of Zn. Faisalabad-08 accumulated about 18% more grain Zn concentration with Zn than Zincol-16 without Zn application. A near target level of grain Zn concentration (36 mg kg−1) was achieved in Zincol-16 only with Zn fertilisation. Over all, the findings clearly signify the importance of agronomic Zn biofortification of genetically Zn-biofortified wheat grown on a low-Zn calcareous soil.

Abstract:In model experiments in soil culture, the effect of different methods of treatment with sodium selenite on the photosynthetic activity of spring wheat variety Zlata was studied under extreme growing conditions. Under drought conditions, the inhibition of the growth of the photosynthetic surface of spring wheat plants was revealed. Under conditions of excessive water supply, a sharp decrease in the area of the assimilating surface of wheat plants was observed. The positive effect of sodium selenite solution on the photosynthetic activity of spring wheat plants was established with insufficient and excessive water supply to wheat plants.
