“…In addition, Wang et al [50] reported that the nitrate nitrogen content was significantly correlated with the availability of K and P in the soil; consequently, the tuber yield of potato was increased. Gao et al [17] and Qiqige et al [51] found that NO 3 − -N achieved higher tuber yield compared with NH 4 + -N. The current results of our investigation are consistent with those obtained by Weixing and…”

Two field experiments were conducted to investigate the effects of three drip irrigation regimes (G1: 120% crop evapotranspiration (ETc), G2: 100% ETc, and G3: 80% ETc) and four nitrogen (N) source treatments (S0: non-fertilized; S1: urea, S2: ammonium nitrate, and S3: ammonium sulfate on water consumption use, water utilization efficiency, chlorophyll, yield and tubers quality of potato (Solanum tuberosum L.; cv Diamond) under a drip irrigation system during two successive winter seasons (2015/16 and 2016/17)). Nitrogen fertilization was applied at 380 kg ha−1 as standard application for potato in the investigated area. The highest tubers yield was obtained from potato grown with G1 S2 (65.8 Mg ha−1), G1 S3 (63.6 Mg ha−1), G2 S2 (64.1 Mg ha−1), and G2 S3 (62.4 Mg ha−1), while the lowest tubers yield was obtained from potato grown with G3 S0 (10.1 Mg ha−1) and G2S0 (17.4 Mg ha−1). Different treatments of N source resulted in a significant increase for water use efficiency (WUtE) compared with unfertilized treatment. For the interaction effect, the highest WUtE was obtained from potato grown with G3 S2 (18.1 kg m−3), followed by G3 S3 (17.6 kg m−3), while the lowest WUtE was obtained from plants grown with G3S0 (3.0 kg m−3). However, the highest chlorophyll content was obtained from plants grown with G1 and any N source, followed by G2S1-3, while the lowest chlorophyll content was obtained from those grown with G3S0. The highest N, S, protein, and P contents in tubers were obtained from plants grown with G3S3, G3S2, and G2S2, while the highest K content in tubers was obtained from plants grown with G1S1 and G1S2. In concussion, the integrative effects of G1 or G2 with S2 or S3 is recommended for high productivity, while the integrative effects of G3S3 and G3S2 are recommended for high quality tubers.

“…Currently, there is sufficient evidence on the effects of nitrogen nutrition on potato tuber production (Qiqige et al, 2017;Maltas et al, 2018). However, the evidence is still limited concerning biomass accumulation and partition to different plant organs under varied nitrogen fertilization doses in different potato cultivars of the tropical Andes.…”

“…Potato yield is strongly influenced by nitrogen fertilization (Van Delden, 2001;Qiqige et al, 2017). The N effect on tuber yield has been well demonstrated (Alva et al, 2002;Maltas et al, 2018).…”

“…Thus, understanding how environmental factors determine growth patterns and production has been one of the most important issues on potato crop research, which aims to help improve the management of agricultural resources (Tiemens-Hulscher et al, 2014;Passos et al, 2017). Nitrogen fertilization is one of the most relevant practices in potato farming systems since nitrogen is the most important nutrient during all phenological potato stages (Van Delden, 2001;Machado & Sarmiento, 2012;Qiqige et al, 2017;Nurmanov et al, 2019).…”

Nitrogen nutrition considerably influences the process of growing and producing potato crops. The aim of this study was to determine the effects of nitrogen nutrition on the pattern of biomass and nitrogen partitioning during the growth of potato crop in Mérida, Mérida, Venezuela. Experimental land plots were set, with a randomized blocks design, and with three different fertilization treatment settings for the "Granola" cultivar. The first one without nitrogen (0-N), the next one with 133 Kg N Ha-1 (133-N), and the last one with 400 Kg N Ha-1 (400-N). In the main phenological stages of the crop, biomass and nitrogen levels were measured for each organ. The performance of the tubers and the total biomass are strongly influenced by the availability of nitrogen and assimilatory biomass. The total biomass production, as well as the biomass and nitrogen partitioning to each organ, showed the following sequence: 400-N > 133-N > 0-N. However, biomass and nitrogen partitioning to the roots and stolons was higher in the treatment with limited nitrogen levels. Proportional changes among aboveground and belowground biomass are adaptive responses to nitrogen deficit conditions, which, in their turn, are determining factors in crop production.

“…Other studies have shown that apart from nitrogen source, the time of application is equally important for tuber yield. In particular, NO 3 − nitrogen may induce higher yields than NH 4 + nitrogen when applied before or during tuber formation, whereas after tuber formation NH 4 + nitrogen was more efficient in terms of tuber yield [9].…”

Potato cultivation is quite demanding in inorganic nutrients and adequate fertilization is a key factor for maximizing yield and producing tubers of high quality. In the present study, a field experiment was carried out to evaluate the effect of various forms of fertilization on crop performance and the nutritional value and chemical composition of two potato varieties (cv. Spunta and cv. Kennebec). For this purpose, five different fertilizer treatments were applied namely: control (C), standard fertilizer (T1), standard fertilizer + zeolite (T2), manure (T3) and slow release nitrogen fertilizer (T4). According to the results, it was observed that slow release treatment (T4) achieved the highest yield for both varieties, while the control treatment presented significantly lower yield compared to the studied fertilization regimes. The dry matter of leaves and shoots was higher in T1 treatment for cv. Kennebec and in T2 and T4 treatments for cv. Spunta, whereas the control treatment presented the highest dry matter content in tubers for cv. Kennebec and T2 and T3 treatments for cv. Spunta. A significant effect of the fertilization regime was also observed on the nutritional value of tubers and more specifically the protein, ash and fat content was increased by treatments T1 and T4, while carbohydrate content was also increased by T3 and T4 treatments for both varieties. Similarly, the total sugars, organic acids, β-carotene and lycopene content was increased in T3 treatment for the Spunta variety, while the antioxidant capacity showed a varied response depending on the fertilizer regime and the tested variety. In conclusion, the fertilization regime has a significant effect not only on the tuber yield but also on the quality of the final product and should be considered as an effective tool to increase the added value of potato crop.
