Foliar Fertilization

A field experiment in growing winter rape was carried out during the period 2009-2011 in a family farm (owned by Mr. M. Bednarczyk) located in Jaroszewice (Lublin region), on podzolic soil. Plant biometric features as well as yield and seed qualitative parameters (oil, protein and glucosinolate content) were evaluated depending on the following rates of soil NPK fertilizers and on foliar fertilization (autumn spraying with the fertilizer solution): 100% and 75% of NPK as well as urea + nickel chelate + MgSO4H2O; 100% and 75% of NPK as well as urea + Plonvit R + MgSO<sub>4</sub>H<sub>2</sub>O). Plots without foliar fertilization (only 100% of NPK) were the control treatment. The other experimental factor was the seeding rate (2.5 kg×ha<sup>-1</sup> – 30 cm row spacing; 4 kg×ha<sup>-1</sup> – 18 cm row spacing). Foliar spraying was done once in the autumn in the second decade of October. Tillage as well as mechanical and chemical control of agricultural pests in the plantation were typical for this plant species and consistent with the recommendations for winter rape protection. A hypothesis was made that the application of foliar fertilizers would have a beneficial effect on winter rape productivity, at the same time maintaining the high quality of raw material. It was also assumed that a reduction in the seeding rate of winter oilseed rape would result in reduced plant lodging and an increased number of siliques per plant; as a consequence, seed and oil productivity would be at a level not lower than that obtained at the higher seeding rate. The present study has proved that foliar fertilization of winter oilseed rape in the autumn period contributes to improved plant winter hardiness and increased productivity. The application of foliar fertilizers also enables the rates of basic mineral NPK fertilizers to be reduced by 25% without detriment to seed yield. Foliar fertilizers have been found to have a weaker effect on changing the chemical composition of rapeseed. The study has shown that, from the productive point of view, it is justified to use the lower seeding rate (2.5 kg×ha<sup>-1</sup>), since winter rape yield (seed and oil yield) did not significantly differ from that found in the case of the higher seeding rate (4.0 kg×ha<sup>-1</sup>).

Purpose. Revealing the dependence of the formation of high yield and quality indicators of winter seeds on the influence of the level of intensification of the cultivation technology in the conditions of the Forest-Steppe of the Right Bank. Methods The results of the conducted researches on the influence of the sowing method, sowing norms of winter rape on its seed productivity are given. The prospect of expanding the sown areas of winter oilseed rape, actualizes research to identify the dependence of the formation of high yields and quality indicators of winter oilseed rape from the influence of the level of intensification of cultivation technology. The research methods used in the field experiment correspond to the methods of field experiments and guidelines. The experiment was established by the method of split sites. Winter rapeseed cultivar Antaria of Ukrainian selection and Exagon hybrid of foreign selection were used for sowing. The generally accepted technology of growing winter rape for the area where the research was conducted was used. Results. The results of the research on the influence of sowing method, sowing norms of winter oilseed rape on its seed productivity show that the highest yield of winter oilseed rape seeds was obtained by sowing ordinary row with a row spacing of 15 cm, and sowing rate in the variety - 0.8 million seeds /ha, hybrid - 0.6 million seeds / ha. It is established that the method of sowing and sowing norms affect the quality of winter rape. The optimal sowing rate of winter rapeseed is for the variety - 0.8 million similar seeds per 1 ha, for the hybrid - 0.6 million similar seeds per 1 ha, when sown in the usual row method with a row spacing of 15 cm. Conclusions. It was found that the highest oil content in winter rapeseed was - 46.98% for sowing in a wide row with a row spacing of 45 cm. Also, this method of sowing was determined by the lowest (0.39%) content of erucic acid, while the content of glucosinolates for this method of sowing was higher (33.1 μmol / g) compared to the usual method of sowing.

The objective of the study was to determine the effect of biostimulants on the concentration of harmful sulphuric compounds called glucosinolates in the seed of three winter oilseed rape cultivars. An experiment was arranged as a split-split-plot design with three replications. The following factors were examined: I – three winter oilseed rape morphotypes: a population morphotype (cv. Monolit), a semi-dwarf restored cultivar (PR 44D06) and a standard restored cultivar (PT 205); II – two sowing methods: between-row spacing of 22.5 cm and 45.0 cm; III – four types of biostimulants: control, Tytanit<sup>®</sup>, Asahi<sup>®</sup>SL and Silvit<sup>®</sup>. The lowest concentration of glucosinolates was determined in the population cv. Monolit (on average 8.84 µmol/g) and the highest in the restored semi-dwarf cv. PR 44D06 (on average 9.84 µmol/g). Application of all of the biostimulants contributed to a significant decline in the concentration of harmful sulphuric compounds compared with control, the lowest concentration being recorded following the spraying with Silvit<sup>®</sup> (on average 8.88 µmol/g). Statistical calculations did not confirm a significant effect of two sowing methods on the characteristics examined.

Winter Oilseed Rape

Agricultural management, environmentally friendly technologies, chemical, organic and bio-based substances used, as well as meteorological factors, have a significant impact on the fluctuations of soil organic carbon (SOC). The aim of this research was to analyze the effect of different biopreparations on the changes of SOC content and the winter wheat and winter oilseed rape yields by assessing the energy consumption efficiency and the environmental impacts. The experimental research was conducted from 2017 to 2019 in three different treatments, in two of which were used either a molasses and magnesium sulphate based-biopreparation (T1) or a bacteria-based biopreparation (T2), while treatment T3 was applied as a control where no biopreparations were used. The dynamics of SOC content were analyzed at two depths: 0–10 and 10–20 cm. For the analysis of energy efficiency indicators and environmental impacts, the greenhouse gas (GHG) and energy consumption conversion equivalents were used. A summary of the results showed that both types of biopreparations had a positive effect on the changes of SOC content, which was especially evident in the deeper layers at 10–20 cm depth, where, irrespective of the crop type, a more significant increase of the SOC content was observed every year of the experiment compared to the control treatment. Biopreparations had a significant effect in increasing the winter wheat and winter oilseed rape yield. The best energy efficiency ratio was observed in winter wheat (4.84) and winter oilseed rape (5.11) in treatment T1. The results of the environmental impact assessment showed that the lowest GHG emissions were recorded in the winter wheat production in treatment T1 at 108.7–149.1 kg CO2eq Mg−1, while the highest were observed in oilseed rape production in the control treatment T3 at 343.4 kg CO2eq Mg−1.

The effect of N-S fertilizers on the molybdenum content in oilseed rape plants was investigated in precision field trials. Evaluation was carried out on unfertilized control and two treatments of single fertilizer rates in the first spring fertilizer application, using 100 kg N/ha in AN treatment (nitrochalk) and 100 kg N/ha + 50 kg S/ha in ANS treatment (ammonium nitrate and ammonium sulphate). The results confirmed the significance of sulphur fertilization for the winter oilseed rape plant&rsquo;s cultivation technology, even on fertile soils in the CzechRepublic. The control treatment produced a yield of 3.7 t/ha, while in the AN treatment the yield was 49% higher, and the ANS treatment was 60% higher. An antagonistic relationship between the sulphate and molybdenum anions in their absorption by the plants was demonstrated. The molybdenum content in the flowering period of the plants was determined in mg/kg as follows &ndash; in the ANS treatment: 0.17 in root, 0.12 in stem, 1.56 in upper leaves, 0.90 in lower leaves, and 1.17 in the flower petals. Higher and statistically more significant molybdenum levels were determined in the AN&nbsp;treatment: 0.21 in the root, 0.19 in the stem, 2.40 in the upper leaves, 1.72 in the lower leaves, and 1.50 mg/kg in the flower petals. The total above-ground biomass of the plants in the flowering period had accumulated molybdenum at 6.06 g/ha in the ANS treatment, and 8.44 g/ha in the AN treatment.

In this study, the agricultural inputs, energy requirements and costs associated with the production of semi-dwarf (PR45 D03 and Avenir) and long-stem (Visby) cultivars of winter oilseed rape were optimized in an experiment with 35-1 fractional factorial design. A field experiment was carried out in the Agricultural Experiment Station in Bałcyny (north-eastern Poland) in 2008–2011. The study investigated the responses of two morphotypes of hybrid cultivars of winter oilseed rape to key yield-forming factors (seeding date, seeding rate, nitrogen fertilization) and yield protection factors (fungal disease control). Agronomic inputs were tested at three levels. Our findings indicate that production technologies (characterized by a different intensity of agricultural inputs) should target the specific requirements of winter oilseed rape cultivars. Semi-dwarf cultivars of winter oilseed rape (PR45 D03 and Avenir) were characterized by higher yield potential at different input levels than the long-stem cultivar (Visby). Semi-dwarf cultivars required higher levels of agricultural inputs than the long-stem cultivar. Semi-dwarf cultivars grown in high-input technologies were characterized by the highest energy efficiency ratio. In contrast, the long-stem cultivar was characterized by the optimal energy input-energy output ratio in the low-input technology. Regardless of cultivar, high-input production technologies were more profitable because the resulting increase in seed yield significantly outweighed the rise in production costs.

Abstract The effort to achieve higher yields at the required qualitative level has led to the intensive studying the problems of the rational usage of the titanium containing fertilisers by the agricultural research in the course the previous thirty years. Therefore, the objective of the experiment was to evaluate the impact of two doses of Mg-Titanit (0.2 l/ha and 0.4 l/ha) on the formation of the aboveground and underground phytomass, also on the total chlorophyll in leaves, on the titanium and nitrogen content in the seeds and straw, on the quantity and quality of winter rape yield. The doses were applied two or three times on the leaves of winter rape (BBCH 50-52, BBCH 59, BBCH 66-67). The experiment was realized on the Haplic Chernozem (48°42´ N, 17°70´ E - Western Slovakia) during two farming years (2009/2010 and 2010/2011). The results showed that all three applications of Mg-Titanit in both doses stimulated the formation of aboveground and underground phytomass of winter rape. The highest growth of phytomass was detected after the second application. The application of Mg-Titanit in the growth phases BBCH 50-52 and BBCH 59 increased the contents of both chlorophylls (a and b), where the growth of chlorophyll b content was more considerable than the growth of chlorophyll a content. The third spraying by Mg-Titanit decreased the content of the total chlorophyll. The application of Mg-Titanit had the positive impact on the yield of seeds, straw and fat content in the winter oilseed rape seeds.

Research was carried out at the Experimental Station of Aleksandras Stulginskis University on Calc(ar)i-Endohypogleyic Luvisol (LVg-n-w-cc) during 2014–2017. The effect of exogenous amino acids on the cold tolerance of the linear cultivar ‘Cult’ of winter oilseed rape (Brassica napus L. spp. oleifera biennis Metzg.) was studied. In autumn the plants were sprayed with L-proline and L-glutamic acid one or two times. The biometric parameters of winter oilseed rape prepared for wintering, the amount of endogenous proline and over-wintering of plants were evaluated. It was determined that exogenous L-proline and L-glutamic acid stimulated the growth of green mass of the winter rape surface, accumulation of dry matter and increase of the root neck diameter in the autumn period. The investigated concentrations of L-proline and L-glutamic acid stimulated a more intensive synthesis of endogenous proline in winter oilseed rape plants during the preparation for wintering. The highest percentage of over-wintering has been determined in the variants where in the autumn plants were sprayed two times with 30 mM l–1 L-proline or 1.5 M l–1 L-glutamic acid.

In order to obtain the information about changes of titanium contents in the phytomass during the growing season of winter oilseed rape and about the titanium contents drawn by the rape yield during two farming years the small plot field trial was established. In the trial the fertilizer Mg-Titanit (MgTi) containing 8.5 g of titanium in 1 liter was used. The experiment consisted of 5 treatments. 0 – control treatment without MgTi fertilizer; 2xTi0.2 – two applications of MgTi in the dose of 0.2 l/ha; 3xTi0.2 – three applications of MgTi in the dose of 0.2 l/ha; 2xTi0.4 – two applications of MgTi in the dose of 0.4 l/ha; 3xTi0.4 – three applications of MgTi in the dose of 0.4 l/ha. The fertilizer was applied in spring during two, or three different growth stages: BBCH 50, BBCH 59, BBCH 66. The first plant sampling was carried out shortly before the first application of fertilizer (BBCH 50). The second, third and fourth sampling was taken 2–3 weeks after the application of Mg-Titanitu (BBCH 59, BBCH 66, BBCH 71). The obtained results showed that the titanium content in the phytomass of rape was falling during the monitored period. The titanium content in the rape aboveground phytomass varied in the interval from 16.81 to 67.6 mg/kg and in the root in the interval from 56.6 to 258.81 mg/kg. The titanium application on plant leaves in the quantities from 3.4 to 10.2 g per hectare of soil did not have the unambiguous impact on the titanium content in the rape phytomass. In the yield of one tonne of seed and appropriate quantity of rape straw on average 20 grams of titanium was taken in.

Foliar Fertilization

Foliar fertilization provides cultivated plants with the necessary nutrients during the growing season. The conducted field experiment was aimed at comparing the effectiveness of different variants of foliar fertilization applied in the cultivation of winter oilseed rape (Brassica napus L.), cultivar ‘ES Cesario’. The experimental factors were: A (control), B (YaraVita Brassitrel Pro), C (YaraVita Brassitrel Pro and YaraVita Thiotrac), D (YaraVita Brassitrel Pro and YaraVita Bortrac), E (YaraVita Brassitrel Pro and YaraVita Bortrac and YaraVita Thiotrac) and F (YaraVita Thiotrac). Weather conditions were variable over the years of the study and had a modifying effect on most of the tested parameters. Intensive foliar fertilization (variants D and E) resulted in a significant increase in the number of pods per plant, seed and fat yields, and SPAD (soil plant analysis development) and LAI (leaf area index) indices compared to the control. The protein yield was the highest after fertilizer applications in variants C and E. The use of YaraVita Thiotrac alone (variant F) did not provide the expected results. Foliar fertilizers applied in variant D increased Gs (leaf stomatal conductance) measurements and fat content in seeds but decreased TSW and seed protein content. It was shown that intensive foliar fertilization (variants D and E) increased seed boron content compared to YaraVita Thiotrac fertilization and the control. Fat and protein yields were strongly positively correlated with seed yield (r = 0.93 and r = 0.71, respectively). The best economic effect was obtained after applying foliar fertilization in variants D and E; therefore, they can be recommended for agricultural practice.
