Modern technologies of cultivation of crops directly depend on climatic parameters: temperature, amount of precipitation and their distribution by months. Crop productivity can be controlled by studying and understanding the influence of the climatic potential of Western Siberia. This paper is devoted to its features. Analysis of the influence of abiotic factors on the yield of spring barley for the period 2014-2019 showed that: the sum of effective temperatures of 1500°C, necessary for the growth and development of plants, accumulates annually; the harvest is formed by atmospheric precipitation for five months (May-September), which is 60% of the average annual norm with fluctuations from year to year from 12.1 to 38.0% (303.6-373.7 mm); the hydrothermal coefficient for May-July has an average effect on the yield of the Abalak, Acha, Vorsinsky 2 varieties (the coefficient of variation of the yield is 11.9, 14.9 and 16.3%, respectively) and significant effect on the crops of the Chelyabinsky 99 variety (the coefficient of variation is 25.7%). The Abalak and Chelyabinsky 99 varieties turned out to be more responsive to changes in growing conditions, as evidenced by the values of the regression coefficient (bi) (1.04 and 1.48) exceeding unity. The Acha and Vorsinsky 2 varieties are characterized by a weak response to improved growing conditions.

Potato (Solanum tuberosum L.) is an important tuber crop that is highly affected by poor soil fertility and nutrient disparities. Nutrient depletion due to intensive monocropping and poor soil management practices is a serious problem in Ethiopia, including in northwestern areas. Therefore, an experiment was conducted in the East Gojjam zone of northwestern Ethiopia to evaluate the influence of phosphorus and potassium fertilizer rates on potato tuber production. Three phosphorus levels (0, 34.5, and 69 kg/ha−1) and four potassium levels (0, 100, 200, and 300 kg/ha−1) were set out in a factorial arrangement and replicated three times using a randomized complete block design. Data on growth and quality parameters, as well as plant tissue analysis results, were collected. According to the results, the main effects of phosphorus and potassium fertilizer rates statistically affected growth components. The combined effects of phosphorus and potassium fertilizers had a significant influence on quality components (tuber size distribution). Similarly, the interaction effects of phosphorus and potassium fertilizer rates gave the highest response in all nutrient use efficiency parameters. The combined application of 34.5 kg P2O5 and 200 kg K2O fertilizers resulted in the highest medium (28.32 ton/ha−1) and large-sized (20.0 ton/ha−1) tuber yields. The interaction effect of 34.5 kg P2O5 with 100 kg K2O ha−1 yielded the highest agronomic and recovery efficiency values. Hence, a combination of 34.5 kg P2O5 ha−1 and 200 kg K2O ha−1 fertilizer rates can be recommended for the optimal production of potato in the northwestern area.

“…The theoretical wheat K uptake was set at 66 kg K ha −1 according to the recommendations of the official Swiss fertilization guidelines (Sinaj et al 2017). Winter wheat was included in rotation with other crop species since the beginning of the long-term field experiments (Cadot et al 2018;Hirte et al 2021).…”

This study takes advantage of Swiss long-term field experiments (> 30 yrs) with different K fertilization rates at three sites to (i) test the possibility to generalize linear relationships between K extracts (ammonium acetate, K-AA; ammonium acetate EDTA, K-AAE; water, K-H2O; and water saturated with CO2, K-CO2), (ii) determine the K fertilization effect on soil exchangeable K, (iii) determine the K fertilization effect on shoot biomass and grain yield of winter wheat, (iv) analyze the possibility to derive a soil K critical value, and (v) determine a critical plant K (Kc) dilution curve as a function of shoot biomass (SB) using a “classical” and a Bayesian method. Shoot biomass during the growing season, grain yield, and four soil extracts were measured in 2018 after more than 30 years with four to five rates of K fertilization. Unpublished data of soil K-AAE concentrations, and grain yield and K concentrations since the start of the experiments were also used to analyze the relationship between soil K-AAE and the cumulative K budget. The K-AA and K-AAE concentrations can be converted from one to the other [K-AAE = 26.8 + (1.11 × K − AA)], while the relationship between K-H2O and K-CO2 depends on soil pH. The K-AAE concentrations were positively related to the cumulative K budget for K-AAE ranges from a minimal K concentration up to a K holding capacity that were specific to each site. The lack of K fertilization during several decades decreased shoot biomass in 2018 and grain yield over the course of the experiments at only one of the three sites. The K-AAE values corresponding to non-limiting soil K conditions at this site (50—75 mg K kg−1) were close to the critical values previously reported but the large range suggests that more soil parameters should be taken into account to improve the accuracy of the fertilization guidelines. The Bayesian and “classical” methods used for estimating the Kc curve yielded similar results (Kc = 58.21 × SB−0.45) that should be confirmed in future studies under a range of pedoclimatic conditions along with the effect of other nutrients and wheat cultivars.
