Among liquid biofuels the most practical meaning has the biodiesel production from vegetable oil. The European Union has been introducing regulations that oblige fuel corporations to use admixture of biofuels in petrol and diesel fuel oil. That is why, the demand for the rapeseed oil is dynamically increasing. In order to cope with the market’s challenges, Poland must increase (almost twice) the acreage of the rape sowing similarly to other European countries. The research conducted among rape manufacturers in Western Pomeranian province indicate that the growth of the rape participation in the structure of sowings, and plans for next years assume its expansion to more than 30%.

Arbuscular mycorrhizal fungi are the most widespread root fungal symbionts, forming associations with the vast majority of plant species. Ectomycorrhizal development alters gene expression in plant symbionts. In this work we examined the effect of arbuscular mycorrhizal fungi spores on the growth and development of Brassica and on the expression of BnMT2 in winter rape. In a pot experiment, rape seedlings growing on different types of sterile and nonsterile soils were inoculated simultaneously with mycorrhizal fungi spores of Acaulospora longula, Glomus geosporum, Glomus mosseae and Scutellospora calospora. As compared with control plants growing in the absence of spores, ten-week-old seedlings of Brassica napus L. in sterile soil inoculated with arbuscular spores had longer shoots and higher fresh biomass of above-ground plant parts. In other types of substrates enriched with mycorrhizal fungi spores, the plants were smaller than non-inoculated plants. The presence of AMF spores stimulated the elongation growth of hypocotyls in both analyzed substrates. BnMT2 expression was highest in plants growing on the sterile substrate. Generally, the presence of mycorrhizal fungi spores appeared to have an adverse effect on the growth of rape plants.

Clubroot presents a serious threat to cultures of oilseed rape, especially if the share of this plant species in sowing structure is high. This is related to a long-lasting survival of pathogens resting spores in soil. The casual disease agent is Plasmodiophora brassicae Woronin - an obligatory, internal pathogen of Brassicae family which causes the formation of tumors on roots and hypocotyls. Plants with disease symptoms have a confined ability of nutrients' and water uptake and this may cause considerable losses in quantity and quality of potential yield. Monitoring performed in cultivation areas and the information obtained from farmers allowed to confirm a threat of disease occurrence in several voivodeships. At the same time there is a serious danger of the infection spread to other regions of oilseed rape crops. Confining plant infection by clubroot pathogen may be obtained mainly by applying a correct crop rotation, and also by providing resistant varieties for cultivation. In the performed greenhouse experiment, reaction to the infection caused by P. brassicae of chosen winter oilseed rape cultivars was studied. The degree of plant infection was assessed at the growth phase of green bud. It was stated that cv. Mendel revealed significantly the lowest degree of infection, as compared to the other studied cultivars. The other tested varieties were infested in a differentiated degree, however these differences were mostly not confirmed statistically. The infection level was mainly dependent on places of soil derivation.

Yields of oilseed rape harvested by farmers in Poland are usually much below the attainable potential of currently cultivated varieties, mainly because of the insufficient supply of nutrients during the yield foundation period, which determines the final number of secondary branches. This situation is typical of whole Poland, but may take place even on farms where high yields are harvested, for example in 2007. In 2006, 2007 and 2008, the year effect of multi-micronutrient fertilizers on yield of seeds, elements of yield structure and macronutrient content was studied. Multi-micronutrient fertilizers were applied twice over oilseed rape foliage during its pre-anthesis growth (BBCH45 and 53). In 2007, due to a drought in April, the harvested yields of seeds were below the country’s average. However, in each year of the study, a significant increase in the seed yield owing to the foliar application of multi-micronutrient fertilizers was found. The increase in the yield of seeds, averaged for the three years, reached 0.486 t ha–1 for the NPK+MiMo treatment (full set of micronutrients) and 0.36 t ha–1 for the NPK + Mi treatment (without molybdenum). The increments of the oilseed rape yield resulted from an increased number of developed secondary branches. This yield-forming element was an indirect result of the application of multi-micronutrient fertilizers, which affected the nitrogen economy by oilseed rape plants during the foundation period of their growth. At the same time, the increase in seed yield was significantly modified by the total number of developed pods, which is shaped during the yield-forming period of oilseed rape crop growth. Under conditions of the study, the magnesium content in secondary branches was found to be an element significantly correcting their number, thus increasing the yield of seeds.

The effect of differentiated pre-sow ploughing depth (30, 20 and 10 cm) and weed control method (mechanical, chemical, combined mechanical and chemical) on the overwintering, weed infestation, yield and quality of seeds of oilseed rape was tested. Shallower ploughing worsened the main traits of the autumn condition of rape plants. Rape plants treated chemically had better-formed rosettes than those treated mechanically. Ploughing made to the depth of 30 and 20 cm did not significantly differentiate the yield of rape plants. However, a significant decrease (9-13%) in the yield occurred when the ploughing depth went down to 10 cm. The highest yield was obtained from the rape controlled chemically against weeds. The yield-protective effect of the combined mechanical and chemical weed control was comparable to that of mechanical method.

The content and composition of glucosinolates in the leaves of some double low and traditional varieties of oilseed rape (Brassica napus L.), at three different stages of development, was investigated. Double low rape varieties showed lower, general content of glucosinolates of which indolyl glucosinolates were the most abundant, specially at the initial stage of plant development.
