The effects of three nitrogen (N) fertilizer rates (0, 120, and 240 kg N ha(-1)) and two planting times (May or late June/July) on yield and N use of the early cultivar 'Milady' and the late cultivar 'Marathon' of broccoli (Brassica oleracea var. italica) were investigated on three silty loam soils varying in soil mineral N (Nmin) in the southernmost part of Norway during 1999 and 2001. In all crops receiving fertilizer, rapid uptake of N started about three weeks after planting. The relative yield of broccoli heads increased with increasing soil available N (fertilizer N plus Nmin) at planting to 200-250 kg N ha(-1) and then levelled off. The two lower fertilizer rates were more restrictive to yields in early-planted than in late-planted crops. A general increase in harvest index with increasing N rate reflected a stronger effect of N on the head yield than on the total above ground biomass production. The apparent recovery of fertilizer N decreased with increasing N rate and was on average 74% in total above ground biomass and 25% in broccoli heads. Despite a higher N uptake, the average soil mineral N level at harvest increased from 12 kg N ha(-1) on unfertilized plots to 27 and 78 kg N ha(-1) on plots receiving 120 and 240 kg N ha(-1), respectively; this increase was stronger in early than in late plantings and stronger in 'Milady' than in 'Marathon'. The yield of broccoli heads was similar in the two cultivars, but 'Milady' had a lower total biomass production and thus a higher harvest index, presumably due to earlier head initiation.

This paper has provided an overview of experience for sustainable water management in Norway. It covers professional areas of integrated water management including urban stormwater management, hydropower development and environment protection, hydrological data collection and flood control, soil erosion and control measures from agricultural areas, ecosystem conservation in river catchments and sediment transportation, and the long-term development of climate change. Water management should be systematic and predictable, and based on the principle of legality. Selected central acts regulating water management aspects, important regulations including regulations on drinking water, sewage purification, licence fees, safety and supervision of watercourse installations were reviewed. The recognition of the economic value of water is visible in many parts of Norwegian water legislation. Several aspects of urban stormwater management, as a whole of integrated water management, were highlighted in part 1 of the paper. Hydropower development related regulations concerning on environment protection were described in part 2. Floods caused by typical climate in Norway, structural and non-structural measures to mitigate floods were summarised in part 3. Erosion from agricultural areas, control measure, monitoring system were summarised in part 4. Research regarding erosion process in river catchments, glacial erosion, and erosion in clay areas, mountain and arctic rivers, and sediment transportation in rivers were presented in part 5. Climate development in Norway during 1900-2100 was given in the last part of the paper, where regional climate downscale models, empirical and dynamical downscaling, were introduced. Results of climate variation - temperature and precipitation in Norway in the latest 100-150 years and scenarios of climate development during the 21st century were presented.
