“…The seeds of rape grown in the experiment were characterized by the magnesium content of 2.5 g Mg kg -1 DM. This is the value reported in a number of other studies on this issue [Korol et al 1994, Barłóg and Grzebisz 2000, Szczepaniak et al 2017.…”

The subject of the study was an analysis of the influence of two-component mineral fertilizers of Polish, Lithuanian and Russian production on the changes in the soil pH and the contents of available phosphorus and potassium as well as exchangeable magnesium after winter rape cultivation and the content of macroelements in winter rape seeds. The study also focused on the effect of using varying doses of fertilizers. A two-year field experiment was carried out on soil belonging to loamy sand, the IVa bonitation class. The experimental plant was winter rape, DK EXPLICIT hybrid. The experiment was established using random blocks design in 4 replicates. Two factors were compared in the studies: I. factor -3 two-component mineral fertilizers of Russian, Lithuanian and Polish production (POLIDAP®). II. factor -3 doses of fertilization (minimum, optimum, maximum, which were respectively: 1.0, 2.0, 3.0 dt per hectare). Introducing the two-component fertilizers and diversification of their doses was a factor that did not change the soil acidification. The applied two-component fertilizers (Russian, Lithuanian and Polish POLIDAP ® ) caused an increase in the amount of available phosphorus in the soil, with no differences depending on the fertilizer type. Diversification of the two-component fertilizers and potassium salt doses was reflected in a significant, but not proportional to the dose, increase in the amount of available phosphorus and potassium in the soil. While using fertilizers of Russian, Lithuanian and Polish production (POLIDAP®) during rape cultivation, there was no difference in the nitrogen, phosphorus, magnesium and sulfur contents in the seeds of cultivated winter rape of hybrid DK EXPLICIT cv.

“…The application of 240 kg ha −1 of N as AN resulted in a yield reduction. The observed tendencies are broadly explained by assuming an imbalance of applied nutrients or referring to the low nitrogen use efficiency (NUE) of WOSR plants [10,[45][46][47][48][49]. In the studied case, this observation was fully corroborated by the trend of partial factor productivity of N indices, which were calculated based on the N-NO 3 content in the soil at BBBCH 30.…”

Application of nitrogen (N) in contrastive chemical form changes availability of soil nutrients, affecting crop response. This hypothesis was evaluated based on field experiments conducted in 2015/16 and 2016/2017. The experiment consisted of three nitrogen fertilization systems: mineral-ammonium nitrate (AN) (M-NFS), organic-digestate (O-NFS), 2/3 digestate + 1/3 AN (OM-NFS), and N rates: 0, 80, 120, 160; 240 kg ha−1. The content of nitrogen nitrate (N-NO3) and available phosphorus (P), potassium (K), magnesium (Mg) and calcium (Ca) were determined at rosette, onset of flowering, and maturity of winter oilseed rape (WOSR) growth from three soil layers: 0.0–0.3, 0.3–0.6, 0.6–0.9 m. The optimum N rates were: 139, 171 and 210 kg ha−1 for the maximum yield of 3.616, 3.887, 4.195 t ha−1, for M-NFS, O-NFS, OM-NFS. The N-NO3 content at rosette of 150 kg ha−1 and its decrease to 48 kg ha−1 at the onset of flowering was the prerequisite of high yield. The key factor limiting yield in the M-NFS was the shortage of Ca, Mg, O-NFS—shortage of N-NO3. Plants in the OM-NFS were well-balanced due to a positive impact of the subsoil Mg and Ca on the N-NO3 content and productivity. The rosette stage was revealed as the cardinal for the correction of WOSR N nutritional status.

“…Potassium is closely related to oil accumulation during oil seed development. For many species, Potassium fertilizer can increase the oil content (Parveen et al, 2016; Szczepaniak et al, 2017; Hu et al, 2018). The same results were verified in developmental S. tonkinensis seeds in our later research of Zhang et al Magnesium, also related to the carbohydrate metabolism and lipids synthesis (Pawar et al, 2018), showed a similar tendency with potassium, having significant positive correlations with nutrient components.…”

BackgroundStyrax tonkinensis is a great potential biofuel as the species contains seeds with a particularly high oil content. Understanding the nutrient distribution in different parts of the fruit is imperative for the development and enhancement of S. tonkinensis as a biodiesel feedstock.MethodsFrom 30 to 140 days after flowering (DAF), the development of S. tonkinensis fruit was tracked. The morphology change, nutrient content, and activity of associated enzymes in the continuum of the pericarp, seed coat, and kernel were analyzed.ResultsBetween 30 and 70 DAF, the main locus of dry matter deposition shifted from the seed coat to the kernel. The water content within the pericarp remained high throughout development, but at the end (130 DAF later) decreased rapidly. The water content within both the seed coat and the kernel consistently declined over the course of the fruit development (30–110 DAF). Between 70 and 80 DAF, the deposition centers for sugar, starch, protein, potassium, and magnesium was transferred to the kernel from either the pericarp or the seed coat. The calcium deposition center was transferred first from pericarp to the seed coat and then to the kernel before it was returned to the pericarp. The sucrose to hexose ratio in the seed coat increased between 30 and 80 DAF, correlating with the accumulation of total soluble sugar, starch, and protein. In the pericarp, the sucrose to hexose ratio peaked at 40 and 100 DAF, correlating with the reserve deposition in the following 20–30 days. After 30 DAF, the chlorophyll concentration of both the pericarp and the seed coat dropped. The maternal unit (the pericarp and the seed coat) in fruit showed a significant positive linear relationship between chlorophyll b/a and the concentration of total soluble sugar. The potassium content had significant positive correlation with starch (ρ = 0.673, p = 0.0164), oil (ρ = 0.915, p = 0.000203), and protein content (ρ = 0.814, p = 0.00128), respectively. The concentration of magnesium had significant positive correlation with starch (ρ = 0.705, p = 0.0104), oil (ρ = 0.913, p = 0.000228), and protein content (ρ = 0.896, p = 0.0000786), respectively. Calcium content had a significant correlation with soluble sugar content (ρ = 0.585, p = 0.0457).ConclusionsDuring the fruit development of S. tonkinensis, the maternal unit, that is, the pericarp and seed coat, may act a nutrient buffer storage area between the mother tree and the kernel. The stage of 70–80 DAF is an important time in the nutrient distribution in the continuum of the pericarp, seed coat, and kernel. Our results described the metabolic dynamics of the continuum of the pericarp, seed coat, and kernel and the contribution that a seed with high oil content offers to biofuel.
