“…There was a significant interaction between the preceding crops and N fertilizer rate on potato N uptake, demonstrating that these cropping systems helped to increased N fertilizer use by potato, likely due to improved soil conditions (Tables 5-8), which favored potato growth and N uptake. This finding is in accordance with other studies that reported synergistic beneficial effects of organic amendment and mineral N inputs on potato yields [56,63].…”

“…Potato N use efficiency varied from 193 to 258 kg yield kg (Table 11). This finding is consistent with other studies that reported enhanced potato apparent N recovery when combining GMs or other organic amendments such as manures or composts with mineral N fertilizer [56,64].…”

“…Total and marketable tuber yields were 32% and 34% (10.1 and 9.3 Mg ha -1 , respectively) greater in soils previously cropped to cereals and GMs than in soils under continuous potato. Our results are in agreement with numerous studies that found positive effects of crop rotations and GMs on potato production [53,55,56]. In all cases, total and marketable potato yields increased linearly with increasing N fertilizer rates (Table 9).…”

“…Furthermore, increases of apparent N recovery and N use efficiency may reflect better synchronization between N release from green manure residues and potato N demands and thus, lower risk of N leaching losses [14,56]. In both years of the study, potato N uptake, apparent N recovery and N use efficiency were higher in soils previously cropped to summer GMs than cereals or fall GMS.…”

Soil quality decline is a common concern in potato production systems. Including cereals and green manures (GMs) in potato rotation could improve soil productivity and sustain potato (Solanum tuberosum L.) yields and quality. This experiment initiated in Québec, eastern Canada, assessed the effects of two cycles of 2-yr potato rotations with cereals and GMs on soil properties and potato yield and quality, and on disease incidence -1 ) were applied to potato. After two rotation cycles in 2011, soils under cereals and summer and fall GMs had higher soil water-extractable organic C and N contents, nitrate levels, soil respiration, urease and dehydrogenase activities, and a larger proportion of soil macro aggregates (0.25 to 2 mm), compared with the continuous potato. Cereals and summer GMs increased marketable potato yield and specific gravity, whereas fall GMs increased tuber yield but reduced tuber quality. In addition, fall GMs favored the incidence of common scab and black scurf. Summer GMs had higher potato N uptake and N efficiency compared to cereals and fall GMs. Although fall GMs produced higher net returns than cereals and summer GMs, they may not represent a viable long term option to sustain potato production and to enhance soil quality. Results indicated that growing cereals or summer GMs in rotation with potato is an interesting alternative to improve soil properties while sustaining potato yield and quality. A fall GM with a better growth during the fall season may sustain potato yield and quality, if included in longer potato rotation, but this remains to be determined.

“…Since the last three decades, developed countries have put many efforts into designing cropping systems and fertilization strategies which reduce overall N inputs into agricultural ecosystems, thus saving valuable resources and minimizing environmental pollution. Effective N management strategies should include many critical factors that are interrelated, of which the correct rate of N application is considered as the single most important factor in improving N use efficiency (Essah and Delgado 2009;Magdoff 1991;Power and Schepers 1989). While much progress has been made in increasing N use efficiency in most arable crops, achieving efficient N management has proven very difficult and remains problematic in intensive vegetable production (e.g.…”

Nitrogen fertilizer application rates in intensive vegetable production in (South) East Asia have increased exponentially over the past decades, including in the low income countries. While there have been reports of excessive N inputs from e. g. Vietnam, Thailand and Indonesia, very little quantitative knowledge exists on the real extent of the problem. We calculated N balances and agronomic N use efficiencies (ANUE) for a number of typical intensive vegetable rotations in the highlands of Central Java, Indonesia, on fertile Andisols, both for individual cropping cycles (short term) as for 6 consecutive cropping cycles (long term). This was done for farmers practice (FP) treatments, and improved practice (IP) treatments, where N fertilization was significantly reduced. Yields were in general similar in FP and IP, but tended to be slightly higher in IP, with some significant differences. Both the short and long term N balances were always positive and usually very high. Short term N balances ranged from 9 to 559 kg N ha(-1) and 219 to 885 kg N ha(-1) in IP and FP, respectively, while short term ANUE ranged from 8 to 67 and 4 to 39% in IP and FP, respectively. Long term N balances ranged from 627 to 1,885 kg N ha(-1) and 962 to 3,808 kg N ha(-1) in IP and FP, respectively, indicating a massive excess of N supply especially in FP. N balances can thus be drastically reduced with no negative impacts on yield, on the contrary. Soil mineral N in the 0-25 cm layer was in general not very high (6.5-38.8 mg N kg(-1) soil) and not systematically different between IP and FP, probably as a result of excessive NO(3)(-) leaching. Therefore, topsoil mineral N seems to have only limited indicator value under these conditions. Because denitrification losses in these soils are not very high, most N in excess of the crop requirements will be lost by leaching. Quantitative data on N balances as obtained here may be used to sensitize policy makers and farmers about the threat of current farming practices to the environment, and to improve economic performance

Nitrogen Management Can Increase Potato Yields and Food Security for Climate Change Adaptation in the Andean Region

et al. 2023

The Andean region of Ecuador is being impacted by climate change, and improved best management practices for agriculture are needed to increase yields and food security. We conducted a study comparing different nitrogen (N) rates to determine the optimum N application rate for potato (Solanum tuberosum L.) systems in this region. We examined five application rates of N: 0, 100, 200, 300, and 400 kg N ha − 1 . The results suggest that an N application rate of 300 kg N ha − 1 increased productivity and net income by 87% and 146%, respectively, compared to no application of N. We transferred these improved practices to farmers, and all farms increased their yields and net economic returns. The average yields and net economic returns for these farmers increased by 50% and 64%, respectively. Additional N use efficiency (NUE) studies are needed to continue increasing yields and economic returns for farmers in the Andean region.
