6. Performance of forage maize at high latitudes : plant development, agronomy and nutritive value
Sammanfattning : Following the development of earlier maturing hybrids the cultivation of forage maize (Zea mays L.) in Northern Europe has markedly increased in recent decades. This has raised needs for greater knowledge regarding the performance of forage maize in marginal areas, such as Sweden, under current conditions. LÄS MER
7. Rhizobacteria associated to Vitis vinifera and their effect on the control of Xiphinema index, Meloidogyne ethiopica and Vitis growth
Sammanfattning : Plant-parasitic nematodes are one of the most important pests affecting the growth of vineyards due to the destruction of new roots. Several species are associated with this problem, the most important being the ectoparasite Xiphinema index and the endoparasite Meloidogyne ethiopica. LÄS MER
8. Use of rhizobacteria for the alleviation of plant stress
Sammanfattning : Plant growth promoting rhizobacteria are beneficial microbes able to induce plant stress tolerance and antagonise plant pathogens. The present study showed that wheat seedlings pre-treated with Bacillus thuringiensis AZP2 had better tolerance to severe drought stress and showed 78% greater plant biomass and five-fold higher survivorship compared to wheat seedlings not treated with the bacterium.

9. Effects of fertilisation with biogas residues on crop yield, soil microbiology and greenhouse gas emissions : recycling of plant nutrients from bioenergy production
Sammanfattning : The amount of residues generated by biogas production has increased dramatically due to worldwide interest in using renewable energy. Biogas residues (BRs) originate from anaerobic degradation of different types of rural and urban organic wastes and have been proposed as organic fertilisers because of their high content of ammonium and other valuable macro- and micro-nutrients.

10. Local and landscape-level impacts of agricultural intensification on arthropod communities and their interaction networks
Sammanfattning : Arthropods play a central role in agricultural landscapes being responsible for the delivery of many ecosystem services such as pollination, biological pest control, and nutrient cycling. But the current global decline of arthropods is intensified by habitat modification, loss and fragmentation, pesticide use and other intensive management practices. LÄS MER
