“…In addition, the discrepancies between N rates and observed yield may be related to the influence of other factors such as agronomics and producer management (LUZ; QUEIROZ; OLIVEIRA, 2014). Regarding management aspects, it was shown that some potato cultivars used for processing required about 150% more N and K than that of table potatoes (DAS et al, 2015). Similarly, we observed that the Atlantic-MG cultivar (used for processing) needed higher N inputs than that of Ágata-MG (by 23.7%) in order to achieve high yield; nonetheless, the Atlantic-MG cultivar showed lower yield.…”

The use of fertilizers at appropriate doses positively impacts the production and the environment. Therefore, we aimed to evaluate the influence of nitrogen (N) rates on the crop yields of the potato cultivars, Ágata and Atlantic in Unaí, Minas Gerais (MG), and Ágata in Mucugê, Bahia (BA), Brazil. The cultivation of Ágata and Atlantic was conducted in MG from May to August and June to September 2014, respectively. In BA, Ágata was cultivated between September and December 2014. A random block experimental design was used with treatment rates of 0, 30, 70, 120, and 280 kg ha-1 of N. The macro and micronutrient concentrations in potato leaves were evaluated. At the end of the growth cycle, the production of tubers was also evaluated. In the absence of N application, it was observed that P, K, S, and B were below the adequate levels in Atlantic-MG, the S and Zn levels were lower than the adequate levels in Ágata -MG, and the N, K, Mg, and S levels were less than the adequate levels in Ágata-BA. The other nutrients met the needs of the potato, with the N increase being favorable to the levels of most nutrients in all experiments. The maximum rates of N varied between 138 and 194 kg ha-1 in the high and low cationic exchange capacity (CEC) regions, respectively. The knowledge of the interaction among soil attributes, climate conditions and crop specificities allows for the improved prediction of the dosage of N and a reduction in the optimum amount without affecting yields.

“…Plant height was 26.5% higher in plots treated with half FYM and half blended fertilizers as compared to the control. Das et al (2015) reported a similar response of potato height on a different variety. The significantly higher effects of combined organic and mineral fertilizers on yield components of potato might be attributed to their complementary effects, whereby the inorganic fertilizers enable the immediate availability of nutrients while the FYM supply nutrients slowly throughout the growing period and improve the soil properties such as soil porosity and reduced soil acidity (Fahmy et al, 2008).…”

Potato (Solanum tuberosum) is the world’s third most important food crop. However, potato productivity is very low in acidic soils that cover about 50% of the arable land in the world. Therefore, the aim of this study was to evaluate the effect of sole and integrated farmyard manure (FYM) and different types mineral fertilizers on yield, yield components and economic returns of potato in acidic soil of Ethiopia. Six treatments: 1) Control (without fertilizer), 2) sole application of the recommended NP (RNP) fertilizer (11 kg/ha N and 40 kg/ha P), 3) sole FYM (28.8 t/ha FYM), 4) half dose of recommended NP fertilizer and half dose of the FYM, 5) blended fertilizer formulated as 17.3 kg N, 34.7 kg P2O5, 7.41 kg S, 2.23 kg Zn, 0.3 kg B + 100 kg/ha), and 6) half blended and half FYM, were arranged in a randomized complete block design. The results revealed that potato plants amended with sole blended fertilizer, and integrated FYM and mineral fertilizers doubled fresh tuber yield as compared to the control. The RNP fertilizer gave the lowest (α < 0.05) marketable potato yields of all the fertilizer treatments. Applications of sole blended or integrated FYM and mineral fertilizers resulted in the highest net benefit with acceptable marginal rate of return. Integrated use of FYM and mineral fertilizers is crucial for improved and sustained smallholder potato production in acidic soils. Further studies are required to examine the long-term effects of blended fertilizers on soil properties.

“…According to Banerjee et al [55], agronomic efciency was not afected by higher levels of fertilizers as compared to lower levels. Tis is due to the fact that the input-output relationship follows the law of diminishing returns when it comes to the relationship between N and yield, [64]. In this regard, the efciency of the variety to use the nutrient and the economical application of N fertilizers are critically important.…”

Sweet potatoes serve as a staple food and animal feed in Africa and serve as a source of raw materials for the food, feed, pharmaceutical, cosmetic, chemical, and energy industries. The yield of orange-fleshed sweet potatoes is increased when nitrogen (N) and phosphorus (P) are added to low-fertility soils. The objective of this study was to evaluate the nutrient uptake and use efficiency of orange-fleshed sweet potato varieties under applied N and P. The experiment was conducted for two growing seasons (2019 and 2020) under rain-fed conditions in the field. The study included five orange-fleshed sweet potato varieties (Kulfo, Kabode, Alamura, Dilla, and NASPOT-12), three N levels (0, 23, and 46 kg·N·ha−1), and two levels of P (0 and 46 kg P2O5·ha−1) fertilizers designed in 5 × 3 × 2 with α-lattice design in factorial arrangement using 3 replications. The interaction effect of variety, N, and P fertilizers affected nutrient uptake, physiological efficiency, and agronomic efficiency of sweet potatoes. NASPOT-12 was the better variety in nutrient uptake but poor in apparent recovery at all levels of N and P. The highest nutrient uptake, agronomic efficiency, and physiological efficiency were observed on NASPOT-12 when subjected to 23 kg N·ha−1 and 46 kg P2O5·ha−1. Overall, NASPOT-12 with 23 kg·N·ha−1 and 46 kg P2O5·ha−1 could be recommended for its high nutrient uptake, agronomic, and physiological efficiencies.
