Opis:: In view of the predicted increase in sulphur deficiency in crop production, a study was undertaken to assess the effect of fertilization with this nutrient on criteria determining the biological value of narrow-leafed lupin seeds (total and true protein, their ratio, nitrates and amino acid composition). The study was based on a three-year, three-factor field experiment, in which the Elf cultivar of narrow-leafed lupin (Lupine Angustifolius L.) was grown on light soil with low sulphur content. The experiment included foliar and soil application of sulphur and its elemental and ionic forms. The application doses were 0, 20, 40 and 60 kg S ha-1. In all years of the study, the sulphur application dose was found to significantly determine the total and true protein content as well as their ratios in the lupin seeds. Application of just 20 kg S ha-1 caused a significant increase in true protein in the lupin seeds and in the proportion of true protein in the total protein, as compared to the control. The CS index for all the essential amino acids showed that the first limiting amino acid in the lupin seed protein was sulphur-containing methionine. As the dose of applied sulphur increased, there was an overall increase in CSmeth. and EAAI. Given the positive effect of sulphur, particularly in the elemental form, on the protein content and amino acid composition of lupin seeds and in reducing the content of harmful nitrates, the use of this nutrient in fertilization of this species is recommended.

Opis:: The study was based on a three-year field experiment conducted on degraded black soil, classified as class IIIb soil in the Polish soil valuation system, with neutral pH, high content of phosphorus and potassium, average content of magnesium, and low content of sulphur. The two-factor experiment was carried out in northern Poland (52°73′ N; 18°88′ E), in a split-block design with four replications. The preceding crop each year was sugar beet. The aim of the study was to evaluate the effect of varied levels of nitrogen (first factor – 0, 60, 120 and 180 kg ha-1) and sulphur (second factor – 0, 20 and 60 kg ha-1) applied to the soil and onto the leaves on the content and ratio of these elements in the seeds of the Star cultivar of spring rapeseed. Little variation was noted between growing seasons in the content of nitrogen and sulphur and in their proportions in the seeds. Application of nitrogen alone (without sulphur) and combined application of nitrogen with sulphur caused an increase in the nitrogen content in the seeds and in the N:S ratio. The sulphur content in the seeds of the plants fertilized with nitrogen and sulphur together was significantly higher than in the seeds of the plants fertilized with nitrogen alone and lower than in the plants fertilized with sulphur alone. The highest N:S ratios were obtained in the seeds of plants fertilized with nitrogen alone, and the lowest – following the application of sulphur alone. Application of nitrogen or nitrogen and sulphur caused an increase in the N:S ratio towards optimal values for fodder crops. The method of sulphur application did not significantly affect its content in the rapeseeds or the N:S ratio.

Opis:: Barley is a cereal of great importance in the crop structure both in Europe and globally. The nutritional value of barley grain is largely shaped by agronomic factors, in particular by fertilisation, which can have a significant impact on the content of individual elements and their quantitative interrelations in grain. The aim of the research was to evaluate yielding, the content of protein and the accumulation of mineral nutrients by the grain of spring barley grown exposed to varied NPK and S fertilisation. The study was based on a three-factor field experiment in a randomised split-plot design with 3 replications. The 1st order factor (A) was fertilisation with nitrogen (n = 3): N1 – 40 kg ha-1, N2 – 80 kg ha-1, N3 – 120 kg ha-1. The 2nd order factor (B) was fertilisation with phosphorus and potassium (n = 2): P1 K1 – 30 kg P ha-1, 80 kg K ha-1; P2K2 – 45 kg P ha-1, 120 kg K ha-1. The 3rd order factor (C) was fertilisation with sulphur (n = 2): S0 – 0 kg ha-1 and S1 – 23 kg ha-1. The study showed that the application of 80 and 120 kg N ha-1 resulted in obtaining a significantly higher grain yield of spring barley and, usually, a higher grain protein content than did the application of 40 kg N ha-1. The increase in yield effected by sulphur fertilisation was significant in relation to the objects without sulphur fertilisation. The highest accumulation of nitrogen, phosphorus, potassium and magnesium was found following fertilisation with a dose of 80 kg N ha-1, as compared with the accumulation with grain from the experimental variant with the application of 40 kg N ha-1. As a result of sulphur application, considerably more nitrogen, phosphorus and potassium was obtained in the grain yield. Sulphur applied in combination with a dose of 120 kg N ha-1 usually caused a significant decrease in the accumulation of the tested macroelements.

Opis:: Garden thyme is a very important essential herbal plant grown in Poland. As well as being able to regulate digestion processes, thyme herbage possesses disinfecting, expectorant, antioxidant, spasmolytic properties. Research has been launched to define the effect of NPK fertilisation on yielding, the content of essential oil as well as the mineral composition of garden thyme (Thymus vulgaris L.) herbage. The experimental factor consisted of NPK mineral fertilisation applied into soil at the following doses per hectare and proportions: A0 – without mineral fertilisation, A1 – 30 kg N + 22 kg P + 100 kg K (N:P:K was: 1:0.75:3.33), A2 – 60 kg N (30 kg N + 30 kg N) + 22 kg P + 100 kg K (1:0.37:1.67), A3 – 90 kg N (45 kg N + 45 kg N) + 22 kg P + 100 kg K (1:0.24:1.11). The experiment comprised 4 fertilisation objects with 4 replications, and the sowing area and the harvest area of 3 m2 plot-1. Nitrogen was applied in the form of ammonium nitrate twice: pre-sowing as well as after plant emergence. Phosphorus and potassium were used pre-sowing, in the form of triple superphosphate 40% and 60% of potassium salt, respectively. The doses of 152 kg NPK ha-1 (1:0.75:3.33) – A1 and 182 kg NPK ha-1 (1:0.37:1.67) - A2 showed the most favourable effect on the yield of fresh weight, air-dried weight and essential oil of herbage as well as the quality characteristics of the yields. The dose of 152 kg NPK ha-1 (A1), including 30 kg less nitrogen, was as favourable as that of 182 kg NPK ha-1 in terms of the content of air-dry weight of herbage, essential oil as well as mineral nutrients. Its application also resulted in a similar yield of essential oil. The application of 212 kg NPK ha-1 (1:0.24:1.11) was economically unjustified since, in general, it decreased the size of the yield of fresh weight of herbage and the values of its parameters studied.
