“…There are two approaches to estimate climate change impacts on the agricultural sector, based on regression and dynamic crop models. Over the past decade, regression models have made a significant progress [9][10][11][12][13]. More sophisticated are dynamic models, which use historical yield data and meteorological observations and are able to simulate crop yields by taking into account the use of fertilizers, regulators of sowing, irrigation, and other techniques [14][15][16][17].…”

An assessment is carried out of future changes in the agroclimatic conditions and crop productivity of spring wheat across the major grain-growing regions of European Russia. Calculations are conducted using a crop model driven by high-resolution, multiple realization regional climate change simulations under the IPCC RCP8.5 scenario. It has been shown that this scenario can lead to a future decrease in the yield of spring wheat by 9.1±2.3% (2030-2039), 10.3±3.2% (2050-2059), and 18.9±2.8% (2090-2099) as compared with the yield at the end of XX century. In the southeastern part of the region, where there are major spring wheat areas, the projected yield change is expected to be -6.7±3.0% by 2050-2059 and −21.5±3.1% by 2090-2099. Fertile lands in the Central Black-Earth region (southwest of Moscow) will suffer even more due to a significant increase in the aridity and decrease of the growing season. There the projected drop in yield is simulated to be 15.8±5.1% by 2050-2059 and 32.9±3.4% by 2090-2099. However, the major losses in total production (gross yield) are expected to occur in the Privolzhsky Federal District where the spring wheat areas amount to 87% of the total cultivated area in the region.

“…Thus, this parameter provides rational information on the correlation between the amount of precipitation in the period, when average day temperature exceeds +10 °C, and sum of temperature in degrees in the same period. The HTC was calculated by applying the formula described by Selyaninov: HTC = ∑ x /∑ t × 10, where ∑ x is the sum of the precipitation and ∑ t is the sum of the temperatures in the period, when the temperature has been above 10 °C …”

“…During the growth period soil samples ( n = 4) were collected every 14 days (10 times per season in each plot) to measure dehydrogenase activity (DHA), as an indicator of soil microbial activity and ecological changes in the soil, as given by previously described methodology . Briefly, soil samples (1 g) were exposed to 0.20 mL of 4 g L −1 2‐ p ‐iodophenyl‐3‐ p ‐nitrophenyl‐5‐phenyltetrazolium chloride (INT) and 0.05 mL of 10 g L −1 glucose solution in 1.00 mL of distilled water for at least 6 h at 28 °C, protected from light.…”

“…For the description of the growing conditions, particularly the balance between moisture and temperature during the vegetation period, the hydrothermal coefficient (HTC) was assessed as the ratio between precipitation to 1/10 of the sum of active temperatures (mean day temperature of the days when it was above 10 • C) [27]. Thus, this parameter provided rational information on the correlation between the amount of precipitation in the period, when the average day temperature exceeded +10 • C, and the sum of temperature in degrees in the same period (Table 3).…”

Possibility of Vegetable Soybean Cultivation in North Europe

The interest in cultivation of vegetable soybeans, also known as edamame, in the North Europe region has increased during the last years due to their high nutritional value and excellent taste properties. During the last decade the possible growing area for soybeans has expanded towards the north due to changes in climate as well as breeding efforts. In order to adopt vegetable soybean growing technology for commercial cultivation in the North Europe region, independent experiments were carried out in Latvia and Norway. This study shows that vegetable soybean is a crop with potential for successful cultivation at higher latitudes, such as the Nordic–Baltic region in North Europe, with yield levels comparable to other regions of the world. We observed that hydrothermal conditions had the most significant impact on soybean plant development. Sowing or planting as early as possible is a key to obtaining sufficient yield levels. In the study, the vegetation period needed to be at least 123 to 127 days, with growing degree days (GDD) at least 650, and hydrothermal coefficient (HTC) above 1. Under such conditions, the obtained marketable yield in Latvia ranged between 3 to 10 t ha−1 during the period of 2017–2019, and 1.2 to 10.5 t ha−1 in Norway. Planting density of 20–25 plants per m2 appeared to be optimal. The variety ‘Midori Giant’ showed the most stable yield outcome, but ‘Chiba Green’ also gave a satisfactory yield.
