“…In the field, potato tuber yield was 26.2 Mg ha -1 (± standard deviation 2.7). This is in the expected yield range of 20-36 Mg ha -1 for fresh market cultivars in North Central USA (Long et al 2004). A moderate yield potential was expected at our site given the short-season cultivar 'Onaway' used, and the late June planting time.…”

Brassica species are increasingly being used as cover crops to suppress soil-borne diseases in potato cropping systems. Experiments were conducted in controlled environments and in the field to evaluate the effects of cover crop root or shoot or a combination of root and shoot tissues on potato root and tuber health. In a lab assay we examined the extent to which volatile compounds released from tissues of two cover crop species, rye (Cereale secale L.) and oriental mustard (Brassica juncea L.), could inhibit mycelium growth of two important potato diseases, Rhizoctonia solani and Pythium ultimum. Twenty-four hours into the lab assay, volatile compounds from all residues suppressed fungal growth. After 48 h, marked suppression of hyphal growth continued in the presence of mustard residues but not in the presence of rye tissues or the control without tissues. A 75 L volume container experiment evaluated the effect of incorporating different quantities of mustard shoot and root tissues (none, comparable to field level and fourfold field level) into R. solani and P. ultimum infested soil on potato growth, root health and tuber disease. In the container study, incorporating mustard shoots at the highest dose increased potato yield by 54% and reduced disease rating to 2.3 compared to a severe rating of 4.4 in the control. In the field trial, potato growth, root health and tuber disease levels were evaluated in plots where disease management involved either incorporation of mustard or rye cover crop roots, shoots and whole plants (roots plus shoots) or standard farmer practice of a fumigated fallow as a control. White root tissue was used as a health indicator, and averaged 58 and 78% in the fumigated control and mustard cover crop treatments, respectively. The highest healthy root tissue status (91%) was recorded where whole plants of mustard were incorporated. In contrast to the visual assessment of root and tuber health, tuber yield in the field was not influenced by cover crop treatment. Across experiments, the incorporation of or exposure to whole mustard plants was consistently effective at suppressing soil-borne fungi and promoting healthy roots and tubers, especially at higher rates of biomass. Mustard should be managed so as to maximize incorporated biomass for effective biofumigation. Multipurpose management requiring removal of mustard shoots is incompatible with promoting potato rhizosphere health.

“…Nitrogen (N) is the most abundant macronutrient in plants that can be absorbed in the form of ammonium (NH 4 + ) or nitrate ). In potato, nitrogen availability influences the development of the aerial parts of the plant, tuber growth and differentiation, and the chemical composition of tubers (Long et al, 2004;Goffart et al;2008;Michalska et al, 2016).…”

This study evaluated the effect of nitrogen fertilization rates on the characteristics of potato starch. The experimental design was randomized block with four replications. The treatments were composed of four rates of N (0, 80, 120 and 160 kg ha -1 ). After 117 days of planting the harvested tubers were sanitized and the starch extracted. The starches of the different treatments were analyzed for the shape and distribution of size, X-ray pattern, crystallinity, amylose, minerals, pasting and thermal properties. Results showed that the fertilization did not cause alteration in the shape of the starch granules but the sizes of granules increased with the application of higher rates of nitrogen fertilizer. All potato starches had X-ray pattern B-type and crystallinity decreased when nitrogen fertilizer rates increased up to 120 kg ha -1. Fertilization did not interfere in content of amylose. Nitrogen rates promoted a decrease in the phosphorus, calcium and magnesium contents in the starches. The starches had their initial and peak temperatures of gelatinization decreased with increasing fertilizer rates, but there was no interference of this practice in the enthalpy. The highest peaks of viscosity and breakdown were observed in starch extracted from potatoes grown with the application of 80 kg ha -1 of Entec® 26 fertilizer. These results indicated important modifications in potato starch properties grown at different rates of nitrogen fertilization and can provide information for starch applications in the food and non-food industries.

“…Similar values for N, P and K application to achieve the same yield were recorded by Šrek et al (2010) on the strip I of the RFE named 'Cereal Crop Rotation' with the same variety of potatoes in 2008. In the RFE, relatively low mineral N application rates contrast with many other world regions where N application rates over 200 kg/ha were necessary to achieve the tuber yield around 30 t/ha (Long et al 2004).…”

Little information is available on how fertilizer application affects concentration of many elements in peeled potato (Solanum tuberosum) tubers and peels. We analyzed how long-term application of cattle slurry and mineral N, P and K fertilizers affects the yield of tubers, their dry matter content and concentrations of elements. In 2009, potatoes tubers were collected in control, cattle slurry (CS), mineral N 4 P 2 K 2 and combined CSN 4 P 2 K 2 treatment of the Ruzyně Fertilizer and Crop Rotation Experiment established on Illimerized Luvisol in Prague (Czech Republic) in 1955. Amount of N, P and K supplied by CS was 138, 30 and 172 kg/ha and the amount supplied by N 4 P 2 K 2 was 110, 31 and 186 kg/ha. Yield of fresh potatoes ranged from 20.6 in the control up to 31.2 t/ha in CSN 4 P 2 K 2 treatment. Dry matter content of unpeeled tubers, peeled tubers and potato peels was not significantly affected by fertilizer treatments probably because of not excessive N application. Normal cropping practices with application of CS and mineral N, P and K fertilizers did not significantly increase concentrations of trace elements in peeled tubers or potato peels on neutral soil with low trace elements availability. Concentrations of many elements (N, P, K, Ca, Mg, Cd, Cr, Cu, Mn, Ni, and Zn) were higher in potato peels than in peeled tubers, but the differences in the case of trace elements were relatively small.
