“…Different research results were obtained by Malhi et al 5 and Nadian et al 24 , who did not show a significant effect of boron fertilization on the value of this trait. A similar tendency was noted by Jarecki and Bobrecka-Jamro 25 after the application of foliar preparations: Basfoliar 36 Extra, Basfoliar 12 – 4 − 6 + S, Solubor DF, Adob Mn and the mixtures: Basfoliar 36 Extra with Solubor DF, Basfoliar 12 − 4 − 6 + S with Solubor DF, while Kwiatkowski 26 after autumn spraying: 100% and 75% NPK and urea + nickel chelate + MgSO 4 H 2 O; 100% and 75% NPK and urea + Plonvit R + MgSO 4 H 2 O and Jankowski et al 27 after the autumn micro and macro-element feeding.…”

The study was based on in 2016–2017, 2017–2018, 2018–2019 field experiment conducted at the University of Natural Sciences and Humanities in Siedlce (Zawady Agricultural Experimental Station), eastern Poland. The studied factors were: I. winter rape cultivars: Monolit—open pollinated cultivar; PT248-F1 hybrid cultivars with traditional growth type; PX115-F1 hybrid cultivars with a semi-dwarf growth type and types of foliar nutrition: (1) control variant without foliar nutrition and amino acids; (2) amino acid; (3) foliar fertilizer sulphur and boron; (4) foliar fertilizer sulphur with foliar fertilizer boron and amino acid. The aim of the study was to determine the effect of foliar application of sulphur, boron, amino acids on the use and feed value of seeds of three winter rape morphotypes. The highest content of crude fat in seeds of the studied morphotypes was found after foliar fertilization with sulphur and boron and amino acids, while the lowest under the influence of amino acids. The highest concentration of total protein was obtained after the application of amino acids, and regardless of the morphotype studied on this object, the same value of this trait was demonstrated. In restored morphotypes, the use of additional foliar fertilization S and B in combination with amino acids did not significantly increase this characteristic compared to the amino acid variant. As a result of the application of amino acids and foliar feeding of S and B, and amino acids, the largest increase in crude fibre content in rapeseeds was obtained, while the application of S and B did not significantly increase this characteristic compared to the control variant. The best feed and use value of seeds were noted in restored morphotypes, with the semi-dwarf variety having the highest fat and crude fibre content. Climatic conditions in the years of research significantly determined the value of seeds. The highest values of the examined traits were obtained in the last year of the study, and the lowest in the growing season 2016–2017.

“…The effect of foliar preparations on seed yield has been presented in studies by many authors. Jarecki and Bobrecka-Jamro (2008) found the best results after feeding plants with Basfoliar 36 Ex plus Solubor DF or with Basfoliar 12-4-6+S plus Solubor DF, with the seed yield increased by an average of 14.1% after their application. Kaur et al (2019) and Pużyńska et al (2018) also noted an increase in seed yield after the application of foliar fertilizers containing sulphur, nitrogen and phosphorus as well as after those containing sulphur and boron.…”

“…The largest increase in the thousand seed weight, by an average of 3.4% compared to the control variant was found on plots with foliar application of sulphur, boron and the biostimulant with amino acids (treatment 4). Jarecki and Bobrecka-Jamro (2008) showed that under the influence of Basfoliar 12-4-6+S with Solubor DF the difference in thousand seeds weight compared to the control was over 1 g (i.e. 24%).…”

Background. An insufficient amount of nutrients in plants results in the disturbance of basic physiological processes, weakens the growth and development of plants, and consequently contributes to a reduction in yield. The aim of this study was to determine the effect of foliar fertilizers containing sulphur, boron and amino acids on the seed yield of three winter oilseed rape morphotypes (Monolit, PX115, PT248).Material and methods. The study was carried out in 2016-2019 at the Zawady Agricultural Experimental Station (52o03' N; 22o33' E) belonging to the University of Natural Sciences and Humanities in Siedlce, in Poland. The field experiment was established in a split-plot design with three replicates. The studied factors were: I – three winter oilseed rape morphotypes: population (cv. Monolit), restored with the traditional growth type (cv. PT248), and restored with the semi-dwarf growth type (cv. PX115); II – types of foliar feeding: 1. The control variant – without foliar feeding and amino acids applied, 2. biostimulant Aminoplant, 3. foliar fertilizer Siarkomag + foliar fertilizer Bormax, 4. foliar fertilizer Siarkomag + foliar fertilizer Bormax + biostimulant Aminoplant.Results. Foliar fertilizers used in the experiment increased the thousand seed weight (on average in the range from 0.9% to 3.4%), seed yield (on average in the range from 2.5% to 18.5%), straw yield (on average in the range from 2.1% to 5.4%) and the harvest index (on average in the range from 4.4% to 7.5%). Of the compared cultivars the semi-dwarf cultivar (PX115) was characterized by the highest yield, while the lowest was from the population cultivar (Monolit). The highest thousand seed weight, main and secondary yields were obtained in the first year of the study which was characterized by a higher total rainfall during seed development and maturation of pods periods compared to the multi-year period, while the lowest levels of these factors was in the vegetation season of 2017–2018 with a humid autumn season and dry period during the flowering and maturation of pods.Conclusion. The most significant increase in the thousand seed weight and seed yield was obtained after applying mixed fertilizers containing sulphur, boron and amino acids. Additional foliar application of the biostimulant Aminoplant on plots with the population and semi-dwarf cultivars did not significantly increase the seed yield as compared to the control. A significant effect of the genetic factor and climatic conditions on the discussed traits has been demonstrated.

Plant growth regulators may reduce the negative effect of environmental stress factors and can contribute to increasing the quality and quantity of the yield. The aim of the research was to determine the effect of biostimulators on the quality of seeds of three winter rape morphotypes. Three varieties of winter rape were used: Poznaniak (population variety), PX104 (hybrid variety restored with a semi-dwarf growth type) and Konkret (hybrid variety restored with a traditional growth type). The varieties were exposed to three treatments: the biostimulator Tytanit®, the biostimulator Asahi®SL and the biostimulator Silvit®, and the control with no biostimulators. Seeds were analysed for content of crude fat, total fat and crude fibres. The biostimulators reduced total protein content (on average from 0.8 to 1.75 g·kg−1 of d.m.) and increased the concentration of crude fat (on average from 0.71 to 1.93 g·kg−1 of d.m.) and crude fibre (on average from 0.15 to 0.84 g·kg−1 of d.m.) compared to the control. PX104 had the highest content of crude fat and total fat protein, and the lowest in crude fibre. The smallest protein content was found in seeds of the long-stem hybrid Konkret, while crude fat was lowest in the population form (Poznaniak), and crude fibre was lowest in long-stem hybrid (Konkret).
