“…The determined number of tubers per plant (Table 5) is a direct consequence of the number of stems per plant (Table 4). These results are in accordance with the results reported by many authors (Zebarth et al, 2006;Knowles & Knowles, 2006;Bussan et al, 2007;Poštić et al, 2012;Momirović et al, 2016), who argued that the number of tubers per plant varied according to changes in the number of stems per plant.…”

The research on the effect of ecological conditions and cultivars on the yield components of potatoes was conducted in Badovinci (Western Serbia) during the period [2008][2009]. The following potato cultivars were included in the experiment: early ('Cleopatra', 'Anushka' and 'Presto'), medium early ('Kuroda', 'Omega' and 'Dita'), and medium late ('Desiree', 'Roko' and 'Jelly'). The fourreplicate field trials were set up using the standard methodology according to the random block design.

“…Precipitation amount during the July-August period 2008, approximate to potato plant requirements and an average number of set tubers, positively affected the share of large tubers. A significant effect of the moisture conditions on the value of tuber yield components was revealed also by Zebarth et al (2006). The authors stated a bigger average tuber weight in wetter than dry years and diversified response of varieties to moisture conditions concerning formation of the number of main stems but also the number of set tubers.…”

“…The number of tubers per plant depends mainly on the number of main stems, which is a cultivar feature highly correlated with seed-potato size. Research of Zebarth et al (2006) and Jamaati-e-Somarin et al (2010) indicate that the number of stems is also influenced by the level of nitrogen fertilization. This relationship was not revealed by Zelalem et al (2009).…”

“…An average tuber weight is determined by many factors which directly or indirectly affect the value of this feature. Planting density, nitrogen fertilization, cultivar properties and moisture conditions have the greatest direct influence (Zebarth et al 2006, Lutra et al 2009, Badr et al 2012. The number of tubers per plant depends mainly on the number of main stems, which is a cultivar feature highly correlated with seed-potato size.…”

The effect of nitrogen fertilization and microbial preparations on yielding and development of potato tuber yield components were assessed in field experiments conducted under soil conditions of Luvic Chernozem. The factors of the experiment were nitrogen fertilization levels: 0, 60, 120 and 180 kg N/ha and the following preparations: BactoFil B10, effective microorganisms and UG max soil fertilizer. Nitrogen fertilization caused a significant increase in marketable yield of potato tubers. Yield increments on individual fertilizer treatments ranged from 66% to 140%. An evident effect of this factor was also visible regarding the yield components values. Increase in the number of main stems per 1 m 2 under the influence of growing nitrogen doses occurred from the fertilization level 120 kg N/ha, whereas the number of tubers per 1 stem increased only to the level of 60 kg N/ha. Each nitrogen dose applied within the range to 180 kg N/ha caused a marked increase in an average tuber weight. Conducted investigations demonstrated an unfavourable effect of microbial preparations on the marketable crop yield of tubers and formation of yield components. On the objects where microbial preparations were applied, the marketable yield was lower by 1.5 to 2.3 t/ha than in the control. Analysis of linear regression revealed occurrence of significant dependencies between the total tuber yield and the values of individual yield components. The relationships were the most visible for an average tuber weight formation as evidenced by the value of coefficient of determination (R 2 = 0.983).

“…Os fotoassimilados, produzidos pela atividade fotossintéti-ca, são direcionados para o crescimento, sendo a partição para os tubérculos um dos fatores determinantes da produtividade da cultura da batata. A produção de matéria seca pela planta e a partição para os tubérculos são influenciados por diversos fatores, tais como interceptação luminosa (Harris, 1992), alta temperatura, por aumentar a senescência foliar e reduzir a capacidade fotossintética (Timlin et al, 2006), fotoperíodo (Haverkort e Verhagen, 2008), cultivar (Zebarth, et al, 2006;Geremew et al, 2007), época de cultivo (Mustonen et al, 2010), manejo da cultura (Geremew et al, 2007) e fertilização nitrogenada (Zebarth e Rosen, 2007). Na batata, há produção de matéria seca na parte aérea e nos tubérculos, que acumulam a maior quantidade, atingindo de 68% a 84% da biomassa total produzida pela planta (Sharifi et al, 2005;Nunes et al, 2006).…”

Objetivou-se avaliar o efeito de doses de nitrogênio (N) sobre os teores e exportações de macro e micronutrientes nos tubérculos de cultivares de batata das mais plantadas no Brasil. Os experimentos foram desenvolvidos na época de outono/inverno, em solo Podzólico Vermelho-Amarelo Câmbico, de textura argilosa. Foram instalados quatro experimentos, simultaneamente, no campo. Em cada experimento foram avaliadas uma cultivar: Ágata, Asterix, Atlantic e Monalisa e cinco doses de N: 0, 50, 100, 200 e 300 kg ha-1, na forma de sulfato de amônio, aplicadas no sulco. Cada experimento foi instalado no delineamento de blocos casualizados, com quatro repetições. Nas cultivares de batata Ágata, Asterix, Atlantic e Monalisa não há efeito de doses de N sobre o teor de K, Ca, Mg, S, Fe e Zn. O teor de N e a exportação de N, P e Mn pelos tubérculos, ao contrário, foram influenciadas pelas doses de N aplicadas em todas as cultivares, embora com padrões diferenciados.
