“…Losavio et al also reported no significant effect of N fertilization on tuber yield by Jerusalem artichoke [16,35]. This is also in accordance with Maltas et al, who reported increasing tuber yields of potatoes with increasing N fertilization, but no significant differences in the higher N rates of about 120 kg N ha −1 under comparable climatic conditions [21]. In general, the expected mineralization in the soil of the present study was quite high.…”

“…PNUtES was highest for the unfertilized treatment, 0 kg N ha −1 . This is similar to several studies, which showed a decreasing amount of carbohydrates in potatoes, sugar beet, and Jerusalem artichoke [21,51,54]. Hence, the aboveground biomass seems to be particularly decisive for plant efficiency, because TNUtE D and TNUtE S did not show any significant differences.…”

“…This is similar to the findings of Fernandes et al who reported a decreasing N uptake efficiency under high N levels above 120 kg N ha −1 for sweet potatoes [16]. Also, Maltas et al reported decreasing N utilization and uptake efficiency with increasing N fertilizer (above 120 kg N ha −1 ) in potatoes [21]. This is explainable by a stronger sink effect of aboveground biomass [20].…”

“…In general, a reaction similar to that of Jerusalem artichoke or potato would have been expected, where higher amounts of N fertilizer delayed maturity [51,53]. This would lead to a decrease in DM content, as well as a decrease in carbohydrates [16,21]. Furthermore, a difference in sugar composition would be expected.…”

“…Besides the impact of N on plant growth and development, an adjusted fertilization strategy is also needed due to economic, as well as environmental reasons [21,22]. In the case where the applied amount of N exceeds the N uptake of the plant, the risk of N losses in ground water rises [23].…”

Impact of Nitrogen Fertilization on Tuber Yield, Sugar Composition and Nitrogen Uptake of Two Yacon (Smallanthus sonchifolius Poepp. & Endl.) Genotypes

The tuberous root crop, yacon, is native to the Andean region and contains high amountsof fructooligosaccharides (FOS) with up to 70% of dry matter. Due to FOS, consumption of tubersmay have health-promoting effects. However, regarding the overall cultivation system, norecommendations exist for farmers on nitrogen fertilization and nitrogen (N) uptake of yacon.Therefore, three different N fertilization levels (0, 40, and 80 kg N ha−1) and two genotypes (brownshelled(BG) and red-shelled (RG)) were examined in a two-year field experiment regarding theirtuber yield, sugar composition, and nitrogen uptake. Tuber yields increased with increasingfertilization level and were highest for B80 and R80 (50 and 67 t FM ha−1), while significantdifferences between the genotypes existed. Sugar and the amount of FOS slightly decreased withincreasing N fertilization level, and ranged between 36% and 73% and 30% and 58% of dry matter,respectively. An overall decreasing amount of FOS led to a slight increase in the amount of FOSwith a higher degree of polymerization. Regarding the N-use efficiency of tubers and the total plant,an N fertilization level of 40 kg N ha−1 seems to favor tuber yield.

Average potato yield in Prince Edward Island, Canada, has been stagnant since 2006. Two field studies were conducted on Charlottetown fine sandy loam soil to address this concern. In the first experiment, two alternative crop rotations, grain corn (Zea mays L.)–sorghum sudan grass (Sorghum × drummondii)–potato (C–SS–P) and soybean (Glycine max (L.) Merr.)–mustard (Brassica juncea (L.) Czern.)–potato (Soy–M–P), were compared to a conventional barley (Hordeum jubatum L.) (under seeded with red clover)–red clover (Trifolium pratense L.)–potato (Solanum tuberosum L.) (B–RedCl–P) rotation. This experiment was conducted for two 3‐year cycles comparing the effects of potato rotation, nitrogen fertilizer, and supplemental irrigation. The second experiment evaluated the inclusion of winter cover crops in a 3‐year potato crop rotation. The profitability of potatoes in each rotation was assessed using a stochastic budget of yields and fertilizer and crop prices. The effects of supplemental irrigation were not significant; however, nitrogen fertilization increased potato yields by 48%. Potato yields and net revenues in C–SS–P increased by 10.5% and 32.6% and in Soy–M–P by 6.7% and 20.5%, respectively, compared to potato in B–RedCl–P rotation. The use of winter rape cover increased potato yields by 18.6% compared to a system without winter covers, although some of these increases could be due to the use of sudan grass instead of red clover in B–RedCl–P rotation. It is recommended that potato producers implement the alternative rotation with additional fertilization and winter cover crops to increase yields and profits.

Aeolian sandy soil, common in Mu Us, China has poor structure and water holding capacity. The soft montmorillonite clay stone was used to adjust the structure and characteristics of sand soil. In this study, the soft montmorillonite clay stone was mixed with sand in the volume ratios of 1:1, 1:2, and 1:5. Soil texture, organic matter content (OMC), and effects on crop yield from 2010 to 2018 were determined. When corn (Zea mays L.) was planted, the clay content, fractal dimension (FD), and OMC of the 1:2 compound soil showed a steadily increasing trend with a higher rate than the 1:1 and 1:5 compound soil. When potato (Solanum tuberosum L.) was planted, the increasing rates of the FD and OMC were largest in the 1:5 compound soil. Potato planting increased the FD of the soil particles by 15.3%, and the OMC was 13.76 times higher than it was prior to planting. Corn and potato crops had the largest sustainable yield index (SYI) and average yield, and the smallest coefficient of variation (CV) in the 1:2 and 1:5 compound soils, respectively. This indicated that 1:2 and 1:5 compound soils allowed for the highest yield stability and sustainability. The 1:2 and 1:5 compound soils were suitable for corn and potato growth, and the compound soil properties exhibited a sustainable and stable development trend. Therefore, this indicates that 1:2-1:5 compound ratios can be used as the optimum sand clay ratios for improving the characteristics of aeolian sandy soil using soft rock.
