| A cultura da batata demanda alto investimento para a sua implantação. Dentre os insumos responsáveis pelo alto custo da lavoura, destacam-se os fertilizantes e a semente. O objetivo deste trabalho foi identificar o efeito de doses de fertilizantes e tamanhos de batata-sementes no crescimento, produtividade e rentabilidade da cultura da batata. O experimento foi conduzido em uma lavoura comercial de batata em Guarapuava-PR, a partir de dezembro de 2010. Os tratamentos foram constituídos de 0, 2, 4 e 6 t ha-1 do fertilizante mineral 4-14-08 (parcela) e batatas-semente do tipo I e III (subparcela), arranjados em esquema de parcela subdividida, em blocos ao acaso, com três repetições. Foram avaliados o comprimento da haste principal, número de hastes, índice... |

| ABSTRACT: Determining the level of absorption of nutrients in the potato crop at different stages of development is important because it allows identification of the time when the elements are most required by plants. The objective of this research was to evaluate the level of nutrient absorption in cultivars after different planting times. Field experiment was conducted in Guarapuava-PR. Treatments consisted of three cultivars (Agata, BRS Clara, and BRS F63 Camila) and two planting times (October and February), in randomized blocks, with three replications in the crop season 2015/16. The total macro and micronutrient content (leaves, stems, and tubers) was quantified at 15 and 45 days after plant emergence. The total dry weight of plants was verified at... |

| ABSTRACT The fertilization of potato crops generally does not take into account the genotype, although genotypes may respond differently to fertilization. This study aimed to determine the yield of new potato genotypes (cultivar BRS Camila and clone CL 02-05), as well as the cultivar Ágata, submitted to four NPK 4-14-8 fertilizer doses (0, 2, 4 and 6 t ha-1) in the crop seasons of 2013/14 and 2014/15. We evaluated the total and marketable tuber yield, total and marketable tuber number, percentage of marketable tuber dry weight, average marketable tuber weight and plant growth period. The experimental design was randomized blocks in split plot scheme, with fertilizer doses allocated as main plots and genotypes as subplots, with three replications. We did... |

| Abstract Little information on the comparative yield of the main potato cultivars (Solanum tuberosum subsp. tuberosum) used in Brazil is available. The objective of this study was to evaluate the performance of modern and old, European and Brazilian potato cultivars in different environments. Two experiments were carried in the field in 2013, in Brazil: in Guarapuava, in the state of Paraná, from January to April; and in Brasília, the Federal District, from August to November. Treatments consisted of six cultivars (origin, year of release): Bintje (European, 1910), Monalisa (European, 1982) and Agata (European, 1990); Baronesa (Brazilian, 1955), Catucha (Brazilian, 1995) and BRS Clara (Brazilian, 2010), arranged in complete blocks at random, with four... |

| ABSTRACT The plant management used in potato crop is usually similar across the main producing regions in Brazil. Same plant spacing are commonly used, despite the differences in climate and soil of the various potato planting areas. The objective of this work was to evaluate the yield of potato cultivars in response to different plant spacing. Experiments were conducted in the field, and the treatments consisted of three cultivars (Agata, BRS Clara and BRS F63 Camila) and three plant spacing (20, 25 and 30 cm) in randomized blocks with three repetitions in two years. The total, marketable and non-marketable tuber yield, total and marketable number of tubers per area and size class, mean total and marketable tuber weight and percentage of tuber dry weight... |

| ABSTRACT The objective of this work was to evaluate the effect of different planting dates on the morphological variables and yield of new potato cultivars. The treatments were three cultivars (Agata, BRS Clara and BRS F63 Camila) and three planting date (October, December and February), carried out in two crop years (2014/15 and 2015/16). Total and marketable yields, average mass of total and marketable tubers, growth period, leaf area index, number and dry weight of the tubers were evaluated. The first planting date resulted in higher yield than the third date. Cultivar BRS F63 Camila was the one with highest yield in this first planting date (47.4 t ha-1), due to greater number of tubers produced in relation to the other cultivars and to higher average... |
