The aim of the research was to determine the copper deposit volume on winter oilseed rape in three development phase (according to the BBCH scale: 12, 14 and 16). The experiment was performed in triplicate at the spraying speed of 0.86 m s-1. Two working fluids were used: foliar fertilizer Mikrovit Copper 80 and a nanocopper preparation, at the dose of 160 g Cu ha-1. The deposition treatment of the plants was conducted in the spraying chamber ‘Aporo1’ at two pressures (0.20 and 0.28 MPa), using two different types of flat fan nozzles. The dried rape plants were mineralized, and then, in order to determine the deposit, the Cu element concentration was measured using the spectrometer. The largest deposit of copper was obtained using the foliar fertilizer Mikrovit Copper 80 and using a double flat fan nozzle DF 120-02. The statistical analysis of the results of the study showed a significant effect of the type of liquid used on the value of copper deposit on winter oilseed rape plants.

This study was conducted to evaluate the effect of different types of fertilizer application on the growth and flowering of 'Puyat' Durian (Durio Zibethenus Murr.); and determine the best fertilizer application for the optimum production of Durian. Ten (10) year old trees at Canoy Durian Farm, Pindasan, Mabini, Compostela Valley Province were tested from November 2015 to March 2016. The experiment was laid out in Randomized Completely Block Design (RCBD) with six treatments, replicated three times. The treatments were: T1- Untreated; T2-Recommended Rate- RR (based on soil analysis); T3- Optimum RateOR + (3kg NPK+1kg MOP); T4- OR+ GOFF; T5- RR+ GOFF; T6- GOFF (Green-shield Organic-based Fortified Foliar Fertilizer).Statistical analysis showed that there were significant differences among treatments in terms of trees with flushes and number of flowers per cluster but no significant effects were observed in canopy diameter and number of flower cluster per tree. Result of the study showed that fertilizer application increased the number of flower per cluster of 'Puyat' Durian and enhanced flushing of durian trees. The study further revealed that organic based foliar fertilizer alone enhanced flowering up to five times higher than without application (control). While numerically, GOFF (Green-shield Organic-based Fortified Foliar Fertilizer) alone had the highest number of flower cluster per tree.

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.

In this experiment, the response of winter oilseed rape cv. SY Alister F1 to diverse foliar fertilization was evaluated. Foliar fertilization with the preparation Insol 5 was applied at the following dates: control (without a foliar fertilizer); autumn; autumn + spring; autumn + twice spring; spring and twice spring. Each variant in which autumn foliar fertilization was carried out contributed to a significant increase in plant density before harvest. In turn, each variant with spring foliar fertilization significantly increased the number of pods per plant compared to the control. Variants with autumn + spring, autumn + twice-spring, and twice-spring foliar fertilization influenced the increase in the soil-plant analysis development index (SPAD), thousand seed weight and protein and fat yield. The leaf area index was the highest after foliar fertilization applied in autumn + in spring or autumn + twice in spring. Foliar fertilization affected a significant increase in seed yield compared to the control. The content of protein and magnesium in seeds was the highest after the fertilizer application in autumn + twice in spring or twice in spring.

Abstract Key message A novel structural variant was discovered in the FLOWERING LOCUS T orthologue BnaFT.A02 by long-read sequencing. Nested association mapping in an elite winter oilseed rape population revealed that this 288 bp deletion associates with early flowering, putatively by modification of binding-sites for important flowering regulation genes. Abstract Perfect timing of flowering is crucial for optimal pollination and high seed yield. Extensive previous studies of flowering behavior in Brassica napus (canola, rapeseed) identified mutations in key flowering regulators which differentiate winter, semi-winter and spring ecotypes. However, because these are generally fixed in locally adapted genotypes, they have only limited relevance for fine adjustment of flowering time in elite cultivar gene pools. In crosses between ecotypes, the ecotype-specific major-effect mutations mask minor-effect loci of interest for breeding. Here, we investigated flowering time in a multiparental mapping population derived from seven elite winter oilseed rape cultivars which are fixed for major-effect mutations separating winter-type rapeseed from other ecotypes. Association mapping revealed eight genomic regions on chromosomes A02, C02 and C03 associating with fine modulation of flowering time. Long-read genomic resequencing of the seven parental lines identified seven structural variants coinciding with candidate genes for flowering time within chromosome regions associated with flowering time. Segregation patterns for these variants in the elite multiparental population and a diversity set of winter types using locus-specific assays revealed significant associations with flowering time for three deletions on chromosome A02. One of these was a previously undescribed 288 bp deletion within the second intron of FLOWERING LOCUS T on chromosome A02, emphasizing the advantage of long-read sequencing for detection of structural variants in this size range. Detailed analysis revealed the impact of this specific deletion on flowering-time modulation under extreme environments and varying day lengths in elite, winter-type oilseed rape.
