In Finland, crop choices are limited, and cultivation is only possible in the regions where production risks and uncertainties are manageable. Climate change progresses rapidly at high latitudes and the thermal growing season is projected to become substantially longer in the future. This study aimed to monitor the regional shifts in major, secondary, minor and novel crops during 1996–2016 in Finland. We used long-term data from the Finnish Food Agency and evaluated changes in time to reach maturity of cultivars of model crops by using official variety trial data. Substantial changes were recorded in cultivation areas of crops, including expansion into new regions. Some of the traditional major crops such as oats (− 20%, i.e. − 75,700 ha from 1996 to 2016), barley (− 19%, − 105,700 ha) and potatoes (− 28%, − 4000 ha) have paved the way for emergent crops like faba beans (increase in area from 58 to 14,800 ha), peas (from 5700 to 13,400 ha), caraway (from 1900 to 18,400 ha) and spring oilseed rape (from 700 to 27,800 ha). Expansion per se was primarily enabled by climate warming, but success requires well-adapted cultivars, existing or emerging markets and industries or exports as well as motivating prices, policy support and valued ecosystem services.

Cultivation of winter oilseed rape hybrids has been introduced as a promising solution to improve the nitrogen use efficiency (NUE) and to reduce the large N balance surpluses in this crop. To achieve a better understanding of the underlying physiological mechanisms, field experiments were conducted over two years to investigate the dynamics of growth and N capture in an oilseed rape hybrid and its parental lines under both low (0 kg ha−1) and high (180 kg ha−1) N supply. The results showed that the dynamic trajectories of crop growth and N capture could be accurately characterized by logistic equation using growing degree days as the independent variable. At both N rates, the oilseed rape hybrid outperformed the parental lines in seed yield and aboveground biomass accumulation, which was more closely associated with the longer duration (td) of the rapid growth period (RGP), than with the higher maximum growth rate (vm). N uptake was the main factor driving genotypic variation in seed yield, with an increasing importance of N utilization efficiency at high N supply. The hybrid had significantly higher N uptake than the parental lines at both low and high N supply, because of larger vm for N accumulation during the RGP, which may present a scope for genetically improving NUE in oilseed rape. High N application enhanced crop biomass production and N accumulation, as a result of prolonged td and larger vm during the RGP. The initiation of RGP for N accumulation occurred after overwinter period, which could not be accelerated by high N supply, suggesting rational distribution of N fertilizer with reduced basal dose. However, larger amounts in spring would be beneficial for a better synchronization to crop N demand with lower environmental risks.

“…It is worth noting that simulations using the GISS and HadGEM RCP 8.5 model scenarios predict an increase in probability of adverse events. In areas where the crop is currently grown, the crop will be more likely suffer from low temperatures [25].…”

This paper presents the results of a 3-year field experiment conducted in north-eastern (NE) Poland to determine the influence of the autumn application of foliar macronutrient and micronutrient fertilizers (control, one application in BBCH (Biologische Bundesanstalt, Bundessortenamt and Chemische Industrie) stage 16 (six leaves unfolded)), two applications in BBCH stages 14 (four leaves unfolded), and 16 (six leaves unfolded) on the growth and development of winter oilseed rape plants, nutrient accumulation, overwintering success, yield components, yield, nutritional value (crude fat content, fatty acid concentrations), and feed value (total protein content, concentrations of acid detergent fiber and neutral detergent fiber, quantitative and qualitative composition of glucosinolates) of seeds. When applied in BBCH stages 14 and 16, foliar fertilizers stimulated the development of leaf rosettes, increased the accumulation of minerals in aerial rosette parts (N, K, and Mg) and roots (K, Cu, Mn, and Fe), and contributed to the overwintering success of winter oilseed rape plants (by 8–11%). The application of foliar macronutrient and micronutrient fertilizers in autumn increased seed yield (by 0.25 Mg ha−1), contributed to a significant increase in the crude fat content of seeds (by 1.3–7.4 g kg−1 dry matter (DM), increased the content of oleic acid, decreased the concentration of linoleic acid, and increased the content of glucosinolates, mostly the alkenyl fraction with antinutritional properties.
