“…Regarding the leaf area index, other studies evaluated this character in Asterix, and found contrasting values, ranging from 1.00 (Zanon et al, 2013) to 3.21 and 4.44 (Cogo et al, 2006), while in the present study it ranged from 4.16 to 4.95. Higher values of leaf area, within certain limits, may be related to Figure 1.…”

The present study aimed to evaluate the plant growth curve of two new potato cultivars, to better understand the dynamics of the plant development throughout the growth cycle, and to subsidize management strategies. Field experiments were carried out in Canoinhas-SC, and Pelotas-RS, in the spring 2019. The new potato cultivars BRS F50 - Cecília and BRS F183 - Potira were compared with the standard cultivar widely grown in the country, Asterix. The experimental design was randomized complete blocks with four replications of plots composed of 43 useful plants, plus borders. Destructive samples of four plants per plot were carried out at 28, 42, 56, 70, 84, 98, and 112 days after planting. Morpho-agronomic characters were evaluated throughout the crop cycle, and the determination of tuber yield was done at its end, harvesting 15 plants per plot. Cecília presented a great development of the aboveground plant parts, and a high tuber yield. Potira also showed a good tuber yield, but was late in the plant development cycle, requiring specific studies on differentiated management of this character. In general, genotypes with a greater development of the aboveground plant parts are more productive, however, in this analysis it is not possible to consider only characters related to the leaf production or even the leaf area, but the plant structure as a whole, including stem development.

“…Regarding the leaf area index, other studies have been done on evaluation of this trait in the cultivar Asterix, used as a check in this work, and found contrasting values, ranging from close to 1.00 (Zanon et al, 2013) to 3.21 and 4.44 (Cogo et al, 2006), while in the present study it ranged from 0.49 to 3.06. Higher leaf area values, within certain limits, may be related to higher interception of solar radiation and associated with higher plant growth and tuber production (Jadoski et al, 2012), but may vary for the same cultivar due to various factors, such as fertilization (Cogo et al, 2006) and irrigation management (Aguiar Netto et al, 2000). The best spatial distribution of the leaf area, which would provide better photosynthetic efficiency, may depend, for example, on stem number per plant (Fernandes et al, 2010).…”

Growth analysis of potato genotypes

et al. 2020

Analyzes of plant growth throughout the crop vegetative cycle are important to know the dynamics of the plant development. Thus the objective of this work was to study the development of potato genotypes throughout the crop cycle, in three environments. Experiments were conducted in Canoinhas-SC, Pelotas-RS, and Brasília-DF, Brazil, in the 2018 crop season. A randomized complete block experimental design with three replicates was used. Traits related to different plant parts of clones F183-08-01 and F50-08-01 and the cv. Asterix were evaluated as a function of time and, at the end of the cycle, for tuber yield. The two clones were found to have high tuber yields, but later development than 'Asterix'; consequently, its management must be adapted to this trait. Leaf mass, leaf number, leaf area index and root mass plus stems were correlated with each other, and leaf area index, leaf number and leaf mass can be quantified through only one of these traits, due to the high correlation between them. There were also positive and significant correlations between the height of the tallest stem and the root plus stem mass and the tuber mass, indicating that more vigorous plants have higher tuber yield.

Resumo -O objetivo deste trabalho foi determinar a curva máxima de diluição do K e ajustar a relação com a curva de diluição do N, durante o ciclo de crescimento e desenvolvimento da batata, para fins de diagnóstico e manejo nutricional. Os tratamentos consistiram de soluções nutritivas com concentrações de K de 3,5; 5,5; 6,5; 8,0 e 9,5 mmol L -1. O delineamento experimental inteiramente casualizado foi empregado com quatro repetições. Quatro plantas de cada tratamento foram coletadas, em intervalos semanais, para análise do crescimento e determinação dos teores de N e K. A curva máxima de diluição do K foi ajustada e a extração máxima foi determinada durante o ciclo de crescimento e desenvolvimento da cultura. Observou-se que a estimativa dos teores máximos de K pode ser obtida a partir dos teores críticos de N. As quantidades de K a serem fornecidas, para obtenção de determinada produtividade, podem ser estimadas com base no teor de N nos tecidos.Termos para indexação: Solanum tuberosum, diluição, nutrição mineral, adubação. Nitrogen-potassium relationship for diagnosis of plant nutritional status and fertilization of the potato cropAbstract -The objective of this work was to determine the maximum K dilution curve and the relationship with the N dilution curve, during growth and development of the potato crop, for nutritional diagnosis and fertilization purposes. Treatments consisted of nutrient solutions with K concentrations of 3.5, 5.5, 6.5, 8, and 9.5 mmol L -1 . The completely randomized experimental design was adopted with four replications. Four plants were harvested, at weekly intervals, to quantify plant growth and to determine N and K tissue concentrations. The maximum K dilution curve was adjusted, and the maximum K uptake was determined, during crop growth and development. It was observed that maximum K concentrations might be estimated from critical N concentrations. Quantities of K fertilizers to be supplied to achieve a pre-fixed crop yield can be estimated from tissue N concentration.
