“…High cereal yield usually depends on low precipitation during winter and in April, whereas higher precipitation is necessary at the straw-shooting and flowering stages. Bujak [47] implied a lack of correlation between yield and precipitation sum. Erekul and Kohn [48] demonstrated that a continued water deficit and above-average temperatures during grain filling lowered the TKW of winter wheat, which was not confirmed in the present study.…”

Effect of Habitat and Foliar Fertilization with K, Zn and Mn on Winter Wheat Grain and Baking Qualities

et al. 2020

Cereal monoculture causes a series of unfavorable changes in field habitat, for example a decrease in technological quality and yield. This system can lead to a shortage of microelements in the diet of poor communities. Moreover, breeding of highly productive plants caused a significant "dilution effect" of the necessary nutrients, such as Zn and Fe. The aim of this work was to determine the effect of two strategies: crop rotation (after rapeseed and many years of monoculture of Galega orientalis Lam.) and foliar fertilization with microelements on the yield, yield elements, physical quality, and farinograph characteristics of winter wheat grain and flour. Results showed that pre-crop preparation and cultivation year have the highest effect on yield, yield components, and qualitative and farinographic characteristics of winter wheat. Foliar additional feeding favorably affected the yield and its components, although the particular fertilization treatment did not significantly increase the yield. Grain quality, its physical characteristics and the rheological parameters of flour were strongly modified by habitat conditions, including weather conditions. Dough obtained from wheat grown after galega showed significantly higher water absorption and prolonged consistency.Zn content. Its consumption in rural areas will probably increase to over 70%, which could lead to an increase in the micronutrient shortage in communities with poor resources [10]. Cereals provide up to 52% of the daily requirement for Zn. Biofortification is a process of plant growth that generates high microelement content through traditional breeding or modern biotechnology. It has been stated that Zn concentration in intensively cultivated soils oscillates between 20 and 35 mg kg −1 , and may be significantly below that level when wheat is grown in soils poor in zinc [11,12]. In the case of wheat grain, Zn bioavailability reaches about 25% of that amount, which is related to the presence of anti-nutritional factors, such as phitynians and the lack of promoter substances in the grain [13].Approximately 30% of the population in developing countries, and about 10% of Americans and Canadians, suffer from Zn shortages [14]. It is estimated that 17.3% of the entire world population is at risk of inadequate Zn consumption, and Zn shortage leads to an estimated annual death rate of 433,000 children under the age of 5 [15]. It was recently found that in Great Britain, Zn consumption in about a quarter of teenagers is lower than the Lower Reference Nutrient Intake (LRNI).There are numerous strategies for improving the intake of micronutrients with plant-based diets and bolstering the condition of plant nourishment in order for microelements to reach food, such as rice diversification, mineral supplementation, enrichment after harvest and bio-diversification [16]. Plant breeding (for example genetic biofortification) and Zn fertilizer application (for example agronomic biofortification) are two important agricultural tools for improving Zn concentration in ...

Since Poland has joined the structures of the European Union (EU), legal regulations at the EU level allow marketing of plant varieties registered in any country of the community. As part of the Post Registration Variety Trials (PRVT) in the Wielkopolska (Greater Poland) voivodeship, the analysis of the interaction of winter triticale cultivars for: height, lodging, diseases, yield and thousand kernel weight in growing seasons 2017–2019 was performed. For farmers, the most important and valuable effect of the research conducted in the PRVT system is the annual “List of varieties recommended for cultivation in the voivodeship”. The main purpose of PRVT research is to help farmers in accurate selection/choice of the most valuable varieties for cultivation, adapted to local conditions. This type of research provides users with continuous information about the variety value for cultivation and use, including their reaction to various agrotechnical factors.

“…The values of each application rate and the results of yield of winter and spring wheat, winter and spring barley, winter and spring triticale, winter rye and spring oats were taken from the Polish Post-Registration Variety Testing System (PRVTS) (Bujak et al, 2013). The PRVTS was established to evaluate the yield and other related traits of newly released cultivars through multienvironmental trials and give reliable recommendation to Polish farmers.…”

The main objective of this study was to assess how much greenhouse gas (GHG) is emitted on average in the life cycle of basic cereals production in Poland. The crops included in the study are winter and spring wheat, winter and spring barley, winter and spring triticale, winter rye and spring oats. The data were taken from the national-scale, multi-environmental trials in 89 locations for years 2010-2015. The research also included comparison of two agrotechnical intensity levels: moderate with the use of nitrogen, potassium and phosphorus fertilization, insecticides, herbicides and pre-sowing treatment -a 1 , and intensive with the additional use of fungicides, growth regulator and higher nitrogen fertilization rate -a 2 , for most cereal species. The results are expressed in the amount of greenhouse gas emitted per hectare and per kilogram of grain in cereal production and also contain the uncertainties attributed to the greenhouse gas emission calculated as propagation of error. The lowest emission for the levels a 1 and a 2 was estimated in the production of winter rye (0.254 ± 0.012 and 0.285 ± 0.014 kg CO 2 eq. kg -1 , respectively). The highest emission in the a 1 level was estimated for spring triticale (0.308 ± 0.021 kg CO 2 eq. kg -1 ) and in the a 2 level for spring wheat (0.334 ± 0.016 kg CO 2 eq. kg -1 ). The conclusion of the study was that the main source of greenhouse gas emission from cereal production in Poland is nitrogen fertilizer use. It was also found that in most crops greenhouse gas emissions per unit of produced grain increased with the crop production intensification. It happens mostly due to the plant nitrogen over-fertilization.
