“…It could be inferred that N was provided later in 2011 cropping season by fall green manure decomposition which delayed potato maturity, resulting in lower tuber specific gravity [61]. Our results corroborate earlier studies in eastern Canada [55] and other investigations that reported that excess N decreases potato specific gravity, particularly during the tuber bulking growth stage [62].…”

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.

“…For the maximum marketable yield, N fertilization rates ranged between 151 and 250 kg ha −1 (Bélanger et al 2000a). Silva et al (2007) obtained the maximum tuber yield of 40.72 Mg ha −1 with 178 kg ha −1 of N. In nine of thirteen Tasmanian field studies, Sparrow and Chapman (2003) obtained potato yield responses to N applied at planting whereas split N applications did not improve tuber yield and quality.…”

The objective of the research was to determine the economic optimum nitrogen (N) fertilization rates and to determine the effects of N fertilization rates on tuber characteristics and fresh mass loss after storage under cold and ambient conditions of four potato cultivars, Ágata, Asterix, Atlantic, and Monalisa. The experiments were, simultaneously, conducted in the same area and similar experimental conditions during the fall/winter period in Viçosa, Minas Gerais State, Brazil. In each experiment, five N fertilization rates (0, 50, 100, 200, 300 kg ha −1 ) were evaluated in a randomized complete block design. For all cultivars, increasing N fertilization rate increased total and marketable yields and tuber dry matter yield up to a maximum following a quadratic model. Increasing N fertilization rate linearly increased the tuber protein concentration of Atlantic and Monalisa and had no effect on tuber pH. N fertilization rate effects on tuber mass, tuber titratable acidity, and fresh mass loss during storage were cultivar-dependent. N use efficiency (tuber yield divided by N fertilization rate) decreased with increase in N fertilization rate. The economic optimum N fertilization rates ranged from 147 to 201 kg ha −1 depending upon cultivar and relative prices of N and potato tubers. Depending on the cultivar, under favorable price conditions (low N price and high tuber price), the economic optimum N fertilization rates to be applied by potato growers were 92-95% of the estimated N fertilization rate for obtaining the maximum potato yield, whereas under unfavorable conditions (high N price and low potato tuber price) the economic optimum N fertilization rates to be applied should be decreased to 86-92% of the rates for maximum yield.

“…Com relação à coloração dos chips, os resultados reforçam observações anteriores feitas por SPARROW & CHAPMAN (2003), os quais concluíram que os efeitos do N sobre a coloração do chips são pequenos e de reduzida importância comercial. Isso significa que os efeitos do N ocorreriam de forma predominante no equilíbrio entre o crescimento da parte aérea e dos tubérculos, o qual determina a partição da matéria seca entre esses dois compartimentos da planta.…”

O objetivo do trabalho foi determinar o teor de matéria seca e a coloração de chips de batata da cultivar Asterix produzidos sob cinco níveis de nitrogênio. O plantio foi feito em 02/09/2003, na UFSM, em sacolas com 4,4dm³ de substrato comercial. Os tratamentos foram constituídos por cinco soluções nutritivas com doses de N de 5,0 (T1), 8,3 (T2), 11,3 (T3), 14,3 (T4) e 16,3mmol L-1 (T5). Os tubérculos foram colhidos em 17/12/2003, aos 104 dias após o plantio, e após 15 dias na temperatura de 20°C foram determinados o teor de matéria seca e a coloração dos chips. O teor de matéria seca dos tubérculos aumentou da primeira até a terceira dose, decrescendo a seguir segundo um modelo polinomial. Os valores foram de 19,5; 20,5; 20,8; 18,6 e 18,4g 100g-1 nas doses de T1 a T5, respectivamente. Somente os tubérculos produzidos com as doses T2 e T3 atingiriam o teor mínimo de matéria seca preconizado pela literatura, que é de 20g 100g-1. Não houve relação entre a coloração dos chips e as doses de N fornecidas. Concluiu-se que o N pode reduzir o teor de matéria seca dos tubérculos e que critérios específicos de manejo da adubação nitrogenada devem ser observados para a produção de tubérculos destinados ao processamento industrial.
