Effect of sulfur fertilization on the concentrations of copper, zinc and manganese in the roots, straw and oil cake of rapeseed (Brassica napus L. ssp. oleifera Metzg)

Abstract

Sulfur application has a significant effect on the yield of oil bearing plants of the family Brassicaceae, especially when the sulfur content of soil is low. Sulfur fertilization also affects the value of plant raw materials, reflected by the concentrations of mineral and biologically active compounds in biomass. The aim of this study was to determine the effect of sulfur application to soil on the concentrations of copper, zinc and manganese in the root residues, straw and oil cake of winter and spring rapeseed. A three-year (2005)(2006)(2007)(2008) field experiment was conducted at the Agricultural Experimentation Station in Bałcyny (NE Poland).In both spring and winter rapeseed, oil cake contained the highest levels of copper and zinc, followed by root residues and straw. The highest concentrations of manganese per kg dry matter (DM) were found in the root residues of winter rapeseed and in the cake of spring rapeseed. The concentrations of micronutrients (Cu, Zn, Mn) were slightly higher in the roots of winter rapeseed, compared with spring rapeseed. Sulfur fertilization decreased copper levels and increased manganese levels in the root residues of spring and winter rapeseed. Sulfur application to soil increased zinc concentrations in winter rapeseed roots, and it had no significant influence on the zinc content of spring rapeseed roots. Spring rapeseed straw contained considerably higher levels of zinc and manganese than winter rapeseed straw. The copper content of dr hab. Krzysztof Jankowski, Chair

The influence of composts on potato tuber, spring oilseed rape seed and threshing residue yields and concentrations of chemical elements in them

“…Rape threshing residues demonstrated a higher Mn concentration after fertilisation with biogas production waste compost. During the experiment Mn concentration in spring oilseed rape seeds was marginally higher than that in threshing residues compared to the concentrations indicated by other researchers: 37.8-40.8 mg kg -1 in seeds and 10.2-20.9 mg kg -1 in threshing residues (Jankowski et al, 2014).…”

“…Zinc concentrations determined in the primary and secondary plant produce during the experiment did not exceed the ones suggested by the majority of researchers, namely: in potato tubers -5.1-35.0 mg kg -1 , spring oilseed rape seeds -55.4 mg kg -1 and in threshing residues -11.5 mg kg -1 (Pollak, Favoino, 2004;Kabata-Pendias, 2011;Jankowski et al, 2014).…”

“…Scientific literature indicates that copper (Cu) concentration in potato tubers range within 3.0-6.6 mg kg -1 , and that in spring oilseed rape seeds and threshing residues -5.2 and 2.0 mg kg -1 , respectively (Kabata-Pendias, 2011; Jankowski et al, 2014). In our research, Cu concentration in potato tubers ranged within an interval of 5.68-8.84 mg kg -1 , and that in spring oilseed rape seeds was 2.55-3.15 mg kg -1 and in threshing residues it was 3.62-5.41 mg kg -1 .…”

Productivity, Energy and Economic Balance in the Production of Different Cultivars of Winter Oilseed Rape. A Case Study in North-Eastern Poland

“…From the economic point of view, the production of winter oilseed rape generates direct profits from the sale of seeds and indirect profits by increasing the yield of successive crops, in particular, cereals [86]. Oilseed rape is an attractive preceding crop for cereals because field residues are rapidly decomposed (narrow C:N ratio), they are abundant in macronutrients and micronutrients, and act as biofumigation agents [87][88][89]. The seed yield of winter wheat increased by 0.8 to 1.5 Mg ha −1 when grown after winter oilseed rape than when cultivated in a continuous monoculture [90,91].…”

Sustainable Food Systems: Relations amongst Nutritional Components in Chickpea (Cicer arietinum L.)

“…Another research (Kahraman et al, 2015) on nutritional quality of chickpea revealed that; in general, protein ratio and Mg content decreased under drought conditions while K and P had an increasing tendency. Furthermore, previous studies (Krzebietke and Sienkiewixz, 2010;Jankowski et al, 2014) reported that foliar application of chemicals on plants realized significant changes in the concentration of nutritional compounds Organic matter is quite important in nutrition of plants. It increases quality of soil, physical structure, aeration and supplementation of water, development of root.…”
