“…En cuanto al número de tallos, la media en el presente estudio fue seis tallos por planta. Por su parte, Rojas y Seminario (2014) informaron cinco tallos por planta en promedio para cultivares nativos; sin embargo, este valor puede variar en función del cultivar, el estado siológico del tubérculo-semilla al momento de la siembra y la densidad de plantación (Silva et al, 2017). En general, cuanto mayor sea el número de tallos por planta o por área, mayor será el número de tubérculos y el rendimiento total, aunque puede disminuir el tamaño de los tubérculos (Toledo, 2016).…”

En el cultivo de papa, la oportunidad y el número de aporques tienen relación directa con el rendimiento, la calidad comercial y los costos de producción. El objetivo de esta investigación fue determinar el efecto del número de aporques en las características biométricas y agronómicas (altura de planta, número de tallos, número de estolones, rendimiento total, rendimiento comercial) y el índice de rentabilidad de tres cultivares nativos de papa: Huayro, Peruanita y Tumbay. Los factores estudiados fueron las tres variedades de papa y dos momentos de aporque; el diseño fue de bloques completos al azar con arreglo factorial 3×2 en cuatro repeticiones. La interacción cultivar por número de aporques fue altamente significativa para las variables rendimiento total y rendimiento comercial. En los tres cultivares, al realizar uno o dos aporques se constató el efecto favorable en mayores rendimientos total y comercial. El cultivar Huayro obtuvo los mayores rendimientos total (kg/ha) y comercial (kg/ha) cuando fue aporcado en dos oportunidades (p < 0,001). Con el aporque cero se observaron pérdidas en el rendimiento total de 86,02 %, 3,67 % y 47,89 % en los cultivares Huayro, Peruanita y Tumbay, respectivamente. En el análisis económico, el cultivar Tumbay, con un solo aporque, obtuvo el mayor índice de rentabilidad; un segundo aporque en los cultivares Huayro y Tumbay no se justifica económicamente.

The variability of potato cultivars and environments in the production area of Nariño-Colombia, demands the adjustment of agronomic recommendations for the improvement of crop management. Physiological behavior and yield of four short-cycle potato cultivars were evaluated: Solanum tuberosum Phureja groups (Mambera, Ratona Morada and Criolla Colombia) and Andigena (Morasurco), under three environments, characterized edaphoclimatically (AH1, AH2, and AH4) and three fertilization levels. The yield components did not present differences between these levels, except for AH2, where level 3 surpassed the others in yield, and AH3 for harvest index with differences between levels. Regarding the cultivars, there were statistical differences in all environments; the highest yield was obtained by Ratona Morada and Mambera in AH4, Criolla Colombia in AH1, and a homogeneous behavior for Morasurco in all environments. In AH1 and AH2 the physiological indexes were similar in proportion and occurrence, while in AH4 the behavior was variable, with higher values in Morasurco and Mambera. ANOVA and discriminant analysis of principal components (DAPC) differentiated Morasurco from Phureja cultivars and Criolla Colombia from Ratona and Mambera. The grouping of environments in the DAPC ratifies the classification of the environments. The nutritional requirements of the genotypes can be limited by elements different from those evaluated; the productivity was mainly influenced by the environments; Mambera and Ratona Morada are established as alternatives in the AH4 environment, and Criolla Colombia and Morasurco in the other environments.

Differential growth and yield responses of local potato cultivars from basic seed tubers

et al. 2021

Potato quality of seed tubers is a determinant factor that allows obtaining high yields, and its use must be a priority for a country or a producing region. Lack of information about how local cultivars perform differentially according to the environment has been identified in order to support potential seeds production programs. The research was carried out in 2018 at the Obonuco Research Center of Corporación Colombiana de Investigación Agropecuaria (AGROSAVIA), with the aim of analyzing the growth and yield of basic tuber seeds of five potato (Solanum tuberosum spp. andigena) cultivars. 1,080 seed tubers from each cultivar (treatments) were planted in a completely randomized block design and three replications. Mean comparison Tukey-Kramer (p≤0.05) test was performed for the yield analysis. From emergency to final harvest, destructive sampling was carried out every fifteen days in order to calculate dry matter and leaf area and establish growth models based on the accumulated degree-days (DD). The yield and proportion of seed tubers per plant were determined according to local resolution for seed certification in Colombia. Growth variables fitted better with the Hoerl, Gaussian, and third-degree polynomial models. The leaf area index of the potato cultivars reached the maximum value at 876 DD, with values ranging from 2.91 to 6.11 DD. The highest yield per plant was obtained by the Ica Única cultivar (2.73 kg plant-1). However, this cultivar showed the lowest percentage of seed tubers, with 50.59% compared to the others, which ranged between 80.82 and 87.40%. Differential potato growth responses through models based on the DD would explain the differences in final yield and seeds tuber production.
