(2015)Brown-heart disorder in rutabaga is a boron deficiency syndrome that renders the inside of the roots brown and makes the crop unfit for market. The connection between boron deficiency and brown-heart was first reported in 1930’s. Brown-heart continues to be a concern for rutabaga growers all over the World, especially in Northern Europe, Canada, United States of America and New Zealand. The aim of this thesis was to compare the effects of various methods of applying boron, in terms of rutabaga yield and brown-heart. The field experiments were done in 2013 and 2014 on Räpi research farm of Apetit Ruoka Oyj in municipality of Köyliö, as part of collaboration between Apetit Ruoka Oyj and Yara Suomi Oyj. The companies aimed to find the best fertilizer solution for the prevention of brown-heart in rutabagas. Treatments were either fertilizer placement or broadcast application. In addition, foliar spraying treatment was used. Nutrient levels of the soil were analysed before planting and after harvest. The nutrient levels of rutabaga leaves before harvest, and nutrient levels of rutabaga roots by the time of harvest, were analysed. Additionally, the yield and number of rutabagas with brown-heart were determined. In experiments done in 2013, the effect of boron treatment on yield was statistically insignificant. In 2014, the fertilizer placement increased the yield as compared to broadcast application. In 2013 the number rutabagas with brown-heart disorder was significantly less within the samples treated with fertilizer placement, as compared to samples treated with broadcast applications. In 2014 the overall number of rutabagas with brown-heart was low, and the differences between treatments were statistically insignificant. Of the rutabaga boron treatments compared in this thesis, the fertilizer placement was more efficient than the broadcast application. Generally, the effect of foliar spraying treatment on yield or quality of the rutabagas was insignificant. In order to achieve high quality rutabaga crop, applying boron with fertilizer placement simultaneous to sowing, is recommended.

(2020)Caraway (Carum carvi L.) is a spice, which belongs to Apiaceae-family. In 2019 25% of the worlds caraway crop was produced in Finland. 99% of it was exported. Caraway is an important cultivated plant in Finland, and broader knowledge of its crop formation is important. As a flowering plant, the sufficient gain of boron is especially vital for caraway. The aim of this study was to study the effect of foliar micronutrient fertilizers, and especially the effect of boron, to crop formation of caraway. The study was conducted as a field experiment in Lantmännen Agro experimental farm in Hauho. The experiment was carried out as a completely randomized block design, with four replicates. The experiment included seven different foliar fertilization treatments. The amount of embels, series and lateral shoots and crop potential were counted, seed and oil crop was determined from the samples, gathered from the plots, Seed samples were sent to oil analysis. In the study above normal crop were achieved with each foliar fertilization treatment, also the control. The soil of the plot was so nutrint-rich that lack of nutrients never existed. Only on statistically significant difference was obtained. It was between two foliar fertilizer treatments when counting the amount of series in an embel. The difference was propably an effect of another factor than the treatments, though. Foliar micronutrient fertilizatin might not be cost-effective farming procedure if soil is already nutrient-rich. Foliar fertilizers may be a good solution in certain situations to back up the nutrient deficit, but they are not a replacement for granular fertilizers.
