“…The ratio between actual and potential yield ranges from 10% to 75%, but typical values are between 30% and 40% (Haverkort and Struik, 2015). Actual potato yields depend on the genetic gain, impact of environment conditions, the introduction of improved agronomic practices and the interaction between these factors.…”

The growing period for early potatoes is extremely short, only 50-80 days from planting to harvest. To obtain a high marketable tuber yield in such a short period good conditions for plant growth must be ensured. In modern agriculture, plant growth stimulants have been gaining increasing importance. Although titanium (Ti) is neither a major nor minor nutrient for plants, it is classified as a beneficial element for plant growth. This paper analyses the effect of dose (0.2 dm ) on the yield and yield components of very early-maturing potato cultivars ('Lord' and 'Miłek'). Potatoes were harvested 75 days after planting (the end of June). Tytanit ® caused an increase in the tuber number and tuber weight per plant, particularly under stress conditions, although the effect of cultivars was not consistent. The growth stimulant did not have any effect on the average tuber weight. Following the application of Tytanit ® , the total tuber yield was higher, on average, by 2.26 t*ha -1 (7.5%), and the marketable tuber yield (diameter above 30 mm) by 1.88 t*ha -1 (6.4%). The tuber number per plant was higher when Tytanit ® was applied at the dose of 0.2 dm 3 *ha -1 . Potato plants produced greatest tubers when Tytanit ® was only applied in the leaf development stage (BBCH 1416). With double Tytanit ® applications, i.e. in the leaf development stage and with repeated treatment in the tuber formation stage, both the tuber number and tuber weight per plant were lower. The Tytanit ® application contributed to improved marketable value of the early potato yield due to a decreased share of small tubers (diameter below 40 mm) and an increased share of large tubers (diameter above 51 mm) especially in a year with a periodical water shortage in the tuber growth period. The examined very earlymaturing potato cultivars showed a differential response to Tytanit ® . The growth stimulant had a greater effect on the tuber number and tuber weight per plant for the 'Lord' cultivar. Following the Tytanit ® application, the total tuber yield of 'Lord' cultivar was higher , on average by 3.71 t*ha -1 (12.7%) and marketable tuber yield by 3.22 t*ha -1 (11.4%). Tytanit ® caused an increase in tuber yield of 'Miłek' cultivar only in year with the highest air temperature and water shortage in June -the total tuber 441

“…As more limiting factors are relieved, nutrient use efficiency must increase. In the case of potato crops, irrigation scheduling (Haverkort and Struik, 2015), remedial measures against soil compaction (Stalham et al, 2005;Rees et al, 2015) and crop sequences could improve nutrient use efficiency.…”

Technologies of precision agriculture, digital soil maps, and meteorological stations provide a minimum data set to guide precision farming operations. However, determining optimal nutrient requirements for potato (Solanum tuberosum L.) crops at subfield scale remains a challenge given specific climatic, edaphic, and managerial conditions. Multilevel modeling can generalize yield response to fertilizer additions using data easily accessible to growers. Our objective was to elaborate a multilevel N fertilizer response model for potato crops using the Mitscherlich equation and a core data set of 93 N fertilizer trials conducted in Québec, Canada. Daily climatic data were collected at 10 × 10 km resolution. Soils were characterized by organic matter content, pH, and texture in the arable layer, and by texture and tools of pedometrics across a gleization-podzolization continuum in subsoil layers. There were five categories of preceding crops and five cultivar maturity orders. The three Mitscherlich parameters (Asymptote, Rate, and Environment) were most often site-specific. Sensitivity analysis showed that optimum N dosage increased with non-leguminous high-residue preceding crops, coarser soils, podzolization, drier climatic condition, and late cultivar maturity. The inferential model could guide site-specific N fertilization using an accessible minimum data set to support fertilization decisions. As decision-support system, the model could also provide a range of optimum N doses across a large spectrum of site-specific conditions including climate change.

“…We demonstrated that in both isolates, the Avr-vnt1.1 gene was expressed at a low level. Expression of inefficient and are responsible for at least half of the yield gap (Haverkort and Struik 2015). The second half is attributed to losses due to diseases with the most severe and ubiquitous being late blight (LB) caused by the oomycete Phytophthora infestans (Fry 2008).…”

“…The potato, introduced in the sixteenth century to the old world, is estimated to have contributed to approximately one-quarter of the population growth in the old world between 1700 and 1900 (Nunn and Qian 2011). Currently, its annual production places the potato as the fourth crop worldwide and third as a food crop (FAO 2014;Haverkort and Struik 2015). The crop is a staple for millions of people but also an important source of income for smallscale farmers in low and middle-low income countries.…”

the Rpi-vnt1.1 gene was shown to be rapidly increased by two-fold and subsequently to have steady state expression for at least 5 days after the inoculation. The Rpi-vnt1.1 gene in addition to other R genes as a stack in farmers' preferred varieties will confer extreme resistance to late blight disease and rotations of plants with different R-gene-stack in time is likely to last longer than plants with single R gene.
