Opis:: The yield increase of vegetables, including common onion (Alium cepa L.), is of great interest to growers. However, higher yield often leads to what is known as genetic dilution of mineral density. A technology of onion fertilization based on elemental sulfur (S0) fertilizers seems to be a simple agronomic measure preventing a decrease in the nutrient concentration in onion bulbs. To verify this hypothesis, field studies were conducted in the 2009 and 2010 seasons. A two-factorial trial consisted of five sulfur fertilizers: Sw (crude form of S0), Sm (micronized S0), SmCu (Sm enriched with copper 0.25%), SmZn (Sm enriched with zinc 0.5%), and AS (ammonium sulfate); and, as the second factor, of two doses of S: 30 and 60 kg ha-1. The NPK plot, included as an independent experimental variant, was used as the control. Yield of onion increased by 13% in response to 30 kg S ha-1, and by 44% when fertilized with 60 kg S ha-1. The yield of bulbs was significantly affected by increasing magnesium and negatively by sodium concentration. The increase in both bulb yields and dry matter content resulted in a simultaneous decrease in nutrient density, except sulfur. The strongest dilution effect was observed for sodium (-33%), iron (-19%), magnesium (-17%) and phosphorus (-16%). Such a negative development can be prevented by applying sulfur fertilizers in an appropriate form. The concentrations of N, P, K, N, and Cu responded most demonstrably to the added ammonium sulfate. The concentrations of S, Zn, Cu, Mn, and Fe were affected by the micronized form of S0 enriched with zinc. The magnesium concentration was the highest in plants fertilized with the crude form of S0.

Opis:: A high yield of oilseed rape can be achieved provided an adequate supply of magnesium and sulfur in critical stages of yield formation. The magnesium status in canopy was studied in the 2008, 2009 and 2010 growing seasons. A one factorial experiment consisting of six treatments, set up to verify the research hypothesis, was as follows: control (C), NP, NPK, NPK+ MgS - 1/3 of total planned dose applied in spring (NPKMgS1), NPK+1.0 MgS dose in autumn (NPKMgMgS2), NPK+MgS - 2/3 in autumn + 1/3 in spring (NPKMgS3). Plant samples were taken at three stages: rosette (BBCH 30), the onset of flowering (BBCH 61) and maturity (BBCH 89). An entire sample was partitioned in accordance with the growth stage into main plant organs: leaves, stems, straw and seeds. The yield of biomass, magnesium concentration and its content was determined in each part of the plant. The magnesium concentration in leaves at the onset of flowering can be used as the first predictor of yield. The predictive strength of the magnesium content in seeds as the final yield predictor corroborated the hypothesis of the importance of magnesium for the seed sink build-up. An analysis of relationships between the magnesium content in plant parts during the growing season and yield of seeds can be used to make an ex-post analysis of factors disturbing the development of yield structural components. The main cause of yield reduction in 2009 as compared to 2008 was the insufficient supply of magnesium to vegetative organs of oilseed plants since the onset of flowering. It was documented that the degree of magnesium supply to a growing silique is critical for the seed yield performance, as noted in 2008. It was also found that any disturbance in the magnesium supply to oilseed rape since the onset of flowering led to reduction in the seed density, which in turn decreased the magnesium seed sink capacity, as the study clearly demonstrated.

Opis:: Grain yield of maize reflects the extent of nutrient imbalance during the growing period. The key objective of a post-harvest analysis of maize, based on chemical characteristics of each part of plants harvested at physiological maturity, is to determine mineral indices which can serve as indicators of grain yield. This assumption has been validated by a long-term field experiment with four levels of potassium and nitrogen supply (0, 100, 150, and 200 kg N ha-1). The potassium application systems were differentiated by the soil fertility level (Medium, High) and K fertilizer (K-, K+). The grain yield of maize was significantly affected by an interaction of the potassium fertilizing systems and years. The importance of this interaction for yield formation manifested itself most distinctly in 2005, when the weather was favourable for plant growth, and in 2004, a season with temporary drought, but not in 2006, when severe drought occurred during the period termed as the critical window. The study implicitly showed that stem leaves can be used as indicators of the management of magnesium by maize while the grain content of calcium indicates how the plant manages that element. The limited size of maize’s physiological sink, i.e. number of kernels per cob, significantly decreases the flow of magnesium from leaves to kernels. Therefore, an elevated concentration and/or content of magnesium in stem leaves can be considered as an indicator of some disturbance of the yielding performance. The calcium concentration in grain showed the highest year-to-year variability among the maize parts. Any increase of this grain characteristic resulted in a yield decline. The key reason was an imperfect structure of the cob due to the disturbed setting up of kernels.
