Productivity of triticale (Triticosecale) in aspect of intercropping with narrow-leaf lupine (Lupinus angustifolius)

The experiment was conducted in the years 2009-2010 in an experimental facility of Wrocław Agricultural University located in Pawłowice (17º02´E, 51º31´N, on a height of 122 meters above sea level.). The goal of the research was to determine the influence of the way the cropping is performed (pure and mixed sowing of narrow-leaf lupine) on the productivity of the Dublet triticale variety. The mixed cropping had four different proportions of triticale and narrow-leaf lupine sowing. The most important morphological attributes of triticale and the elements of cropping structure were determined. As an outcome of the performed research the fact was stated, that the sowing proportions affect both whole plants and seeds attributes changes. Influence of narrow-leaf lupine type on the quantity of grain yield in the mixtures was observed. Majority of biometric attributes was showing a statistically significant dependency on the amount of the sowing mixture components

Effect of Pod Sealant Application on the Quantitative and Qualitative Traits of Field Pea (Pisum sativum L.) Seed Yield

Field pea is used for human consumption or as livestock feed. The yield of pea seeds can be significantly decreased due to the genetically determined tendency of peas to pod shattering. This study aimed to evaluate the effect of pod sealant application on the quantitative and qualitative traits of the seed yield of two pea cultivars: Arwena and Tarchalska grown in south-western Poland in the years 2018–2019. Pod sealant application showed higher values of analysed quantitative and qualitative traits: number of pods per plant, number of seeds per plant, seed weight per pod, 1000-seed weight, seed yield, dry matter of seeds, protein content in seeds, and total protein productivity, except the number of seeds per pod. For both years (2018–2019), the interaction of cultivar and pod sealant application showed a significant effect on the number of seeds per plant, total protein content, total protein productivity, and seed weight per pod in 2019. Therefore, the pod sealant application can be a relatively simple way to improve the yielding of field peas

Wielkość i jakość plonu nasion gorczycy białej w zależności od nawożenia siarką

Background. In white mustard cultivation for seeds, in addition to basic NPK fertilization, fertilization with sulphur is of great importance. Sulphur affects the proper use of nitrogen in Brassicaceae and that stimulates their development and yield. The aim of the present research was to evaluate the effect of various sulphur doses on yield quantity and the chemical composition of seeds of three traditional white mustard cultivars. Material and methods. A field experiment was carried out in the years 2007–2009 in the weather conditions of south-west Poland (Lower Silesian Voivodeship). The experiment was set up as a split-plot design. The primary factor was white mustard cultivars: Metex, Nakielska, and Radena. The secondary factor was diversified sulphur doses: 0, 10, 20, and 30 $kg·ha^(-1)$ . Results. The highest white mustard seed yield was obtained from the cultivar Nakielska when fertilized with 10 $kg·ha^(-1) S$ or $20 kg·ha^(-1)S$. The cultivar Nakielska was also characterized by the highest of all the studied cultivars crude fat productivity per 1 ha at the applied fertilization rates of 10 $kg·ha^(-1) S$ and 20 $kg·ha^(-1) S$, and the highest total protein productivity after the application of 20 $kg·ha^(-1) S$. Total protein and crude fat contents in seeds were significantly modified by the weather conditions in the study years. Conclusion. The study demonstrated that in white mustard cultivation for seeds the optimal sulphur dose amounts to circa 10-20 $kg·ha^(-1)$, and that it is necessary for high yield. Also, the high yield-forming potential of the seed cultivar Nakielska was confirmed.W uprawie gorczycy białej na nasiona obok podstawowego nawożenia NPK istotne jest nawożenie siarką. Siarka wpływa na prawidłowe wykorzystanie azotu w roślinach krzyżowych, stymuluje rozwój i plonowanie. Zbadano wpływ różnych dawek siarki na wielkość plonu i skład chemiczny nasion trzech tradycyjnych odmian gorczycy białej. Doświadczenie polowe przeprowadzono w latach 2007–2009 w warunkach agroklimatycznych Polski południowo-zachodniej (woj. dolnośląskie). Doświadczenie założono metodą split-plot. Czynnikiem pierwszego rzędu były odmiany gorczycy białej: Metex, Nakielska i Radena, czynnikiem drugiego rzędu były różne dawki siarki: 0, 10, 20, 30 $kg·ha^(-1)$. Najwyższy plon nasion uzyskano z odmiany Nakielska nawożonej odpowiednio 10 lub 20 $kg·ha^(-1) S$. Spośród wszystkich badanych odmian charakteryzowała się ona także najwyższą wydajnością tłuszczu surowego z 1 ha przy zastosowaniu nawożenia dawką 10 oraz 20 $kg·ha^(-1) S$ oraz najwyższą wydajnością białka ogółem po zastosowaniu 20 kg·ha -1 S. Stwierdzono, że zawartość białka ogółem i tłuszczu surowego w nasionach była istotnie modyfikowana przez przebieg pogody w latach badań. Wykazano, że w uprawie gorczycy białej na nasiona optymalna dawka siarki wynosi około 20 $kg·ha^(-1)$ i jest niezbędna dla wysokiego plonowania. Potwierdzono także duży potencjał plonotwórczy nasiennej odmiany Nakielska

The Influence of Three Years of Supplemental Nitrogen on Above- and Belowground Biomass Partitioning in a Decade-Old Miscanthus × giganteus in the Lower Silesian Voivodeship (Poland)

Because of the different opinions regarding nitrogen (N) requirements for Miscanthus × giganteus biomass production, we conducted an experiment with a set dose of nitrogen. The objective of this study was to examine the effects of nitrogen fertilization on the biomass yield, water content, and morphological features of rhizomes and aboveground plant parts in various terms during a growing season over the course of three years (2014–2016) in Lower Silesia (Wroclaw, Poland). The nitrogen fertilization (dose 60 kg/ha and control) significantly affected the number of shoots (p = 0.0018), the water concentration of rhizomes (p = 0.0004) and stems (p = 0.0218), the dry matter yield of leaves (p = 0.0000), and the nitrogen uptake (p = 0.0000). Nitrogen fertilization significantly affected the nitrogen uptake in all plant parts (p = 0.0000). Although low levels of nitrogen appeared to be important in maintaining the maximum growth potentials of mature Miscanthus × giganteus, the small reductions in the above- and belowground biomass production are unlikely to outweigh the environmental costs of applying nitrogen. More studies should use the protocols for the above- and belowground yield determination described in this paper in order to create site- and year-specific fertilizer regimes that are optimized for quality and yield for autumn (green) and spring (delayed) harvests

Effect of Nitrogen Fertilization on the Dynamics of Concentration and Uptake of Selected Microelements in the Biomass of Miscanthus x giganteus

This paper presents the effects of nitrogen (N) fertilization on the concentration of selected micronutrients as an important issue in reducing combustion-induced air pollution. We studied the effects of the dose of 60 kg ha−1 N in different terms of biomass sampling on the concentration and uptake of iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu) in the dry matter of the underground and aerial parts of Miscanthus x giganteus in the years 2014–2016. The order of microelement concentrations (mg kg−1) in rhizomes and the aboveground parts of plants was as follows: Fe > Mn > Zn > Cu. N fertilization had no significant effect on the concentrations of the selected microelements in the Mischanthus biomass (except for the Mn concentration in the stems and Cu in the leaves). The results indicated that the quality of the combustion biomass did not worsen under nitrogen fertilization. During the whole vegetation period, the iron concentration increased in the rhizomes and decreased for Zn and Cu. In the aboveground parts of the plant, the concentrations of all tested elements decreased. In turn, the uptake of Fe, Mn, Zn, and Cu (except for Fe in the stems) by rhizomes and the aboveground parts of Mischanthus depended significantly on the N fertilization

The reaction of soybean Glycine max (L.) Merr. to the application of TS series stimulators

A field experiment to assess the response of soybean to the application of TS series stimulators was set up as complete blocks design with four replications. The investigated factor was growth stimulators (seed dressing – TS Osivo and foliar – TS Samson) produced by the Czech company BEIDEA s.r.o., com-pared to the control (without a stimulator). The reason behind the study was the lack of domestic reports regarding the impact of the use of TS series stimulators on the growth, development and morphological agronomic traits and yields of legume crops. The field trials were carried out in 2018–2019 at the Research Station operated by the Institute of Agroecology and Plant Production, Wrocław University of Environmental and Life Sciences, located in the district of Wrocław – Pawłowice (Dolnośląskie voivode-ship). The tested crop was soybean, cultivar Abelina (maturity group 000 ++, breeder Saatbau Linz).Soybean seed dressing with TS Osivo stimulator caused an acceleration of germination and emergence phases from 2 to 4 days compared to the control treat-ment (water). The use of TS series stimulators in soybean culti-vation contributed, in comparison to the control, to a significant increase (by 7.5%) in the plant height before harvest. Simultane-ously, an increase in the height of first pod was observed, which reduces seed losses during harvest. Seed treatment with the TS Osivo stimulator increased seed yield by 5.8% compared to con-trol treatment (without application). Spraying soybean with TS Samson stimulator increased the seed yield by 8.6%. In practice, in order to achieve an increase in soybean seed yield it is recom-mended to apply pre-sowing seed treatment with TS Osivo stimu-lator or foliar application of TS Samson
