“…(N deficiency: Hall et al, 1995;Salvagiotti and Miralles, 2008;Massignam et al, 2009;P deficiency: Pellerin et al, 2000;Colomb et al, 2000;Plénet et al, 2000;Fletcher et al, 2008a;Rodríguez et al, 1998aRodríguez et al, , 2000Lázaro et al, 2010;Sandaña and Pinochet, 2011;Sandaña et al, 2012). However, for potato crops there is much less information about the effects of soil constraints, particularly P deficiency, on RI and its impact on total biomass and tuber yield (Harris, 1992;Jenkins and Ali, 1999). Jenkins and Ali (1999), in three experiments using different cultivars (up to 5) and P rates (0-400 kg P 2 O 5 ha −1 ), concluded that P deficiency decreased dry matter production through reductions in RI.…”

“…Phosphorus is an essential plant nutrient that is especially important in promoting early crop growth (Jenkins and Ali 1999). Potatoes are responsive to P fertilization on soils testing low in P, but yield increases from applied P have also been found on soils testing very high in P (Sanderson et al 2003).…”

A 3 year field study on a loamy sand soil with medium to high soil test phosphorus (P) concentrations (25 to 33 mg kg −1 Bray P1) was conducted to evaluate the effect of P fertilizer rate, source, and timing, and starter nitrogen (N) rate on potato (Solanum tuberosum L. cv. Russet Burbank) yield, tuber size, tuber set, petiole P concentration, and P uptake and distribution within the plant. Nine fertilizer treatments compared banded P rates of 0, 37, 42, and 74 kg P ha −1 , the P sources monoammonium phosphate (MAP) and diammonium phosphate (DAP), P banded at planting vs. split applications at planting and emergence, and starter N rates of 38 and 66 kg N ha −1 . Phosphorus fertilizer application increased total tuber yield and yield of undersized tubers (tubers less than 85 g), but decreased the proportion of large-sized tubers (greater than 285 g). Due to the increases in small, unmarketable tubers, P fertilizer application did not have a significant effect on marketable tuber yield (tubers greater than 85 g). The total number of tubers per plant and the number of undersized tubers were also higher, and the number of large tubers was lower, when P was applied compared with the zero P control. Both the number and yield of undersized tubers increased as P application rate increased. Petiole P concentrations were generally consistent with the rate of P applied, but they varied by year in magnitude and their pattern through the season. Petiole P was positively correlated with the number of tubers per plant, but only correlated for 1 year with differences in total yield. Phosphorus application increased total P uptake due primarily to an increase in tuber P concentration.Increases in total uptake and tuber P increased as P application rate increased, but differences in uptake were small relative to the amounts of P applied. Phosphorus source and timing and starter N rate did not consistently affect tuber yield, number, or size, petiole or tuber P concentration, and P uptake. The results of this study indicate that P nutrition can play an important role in regulating tuber set.Resumen Un estudio de campo en suelo arcillo-arenoso, con concentraciones mediana a alta de fósforo (P) (25 a 33 mg kg −1 Bray P1) se realizó durante tres años para evaluar el efecto de dosis de fertilizante, fuentes de P, control del tiempo y dosis inicial de nitrógeno (N) con papa (Solanum tuberosun L. cv. Russet Burbank) sobre el rendimiento, tamaño del tubérculo, número de tubérculos por planta, concentración de P en el pecíolo y absorción de P y su distribución dentro de la planta. Nueve tratamientos con fertilizantes compararon el P aplicado en bandas a las dosis de 0, 37, 42 y 74 kg P ha −1 , las fuentes de fosfato mono amónico (MAP) y fosfato di amónico (DAP), el P aplicado a la siembra con aplicaciones divididas a la siembra y a la emergencia y dosis de inicio de N de 38 y 66 kg N ha −1 . La aplicación de fertilizante con fósforo aumentó el rendimiento total de tubérculos y de tubérculos pequeños (menos de 85 g), pero disminuyó la propo...

“…The increase in the TB of potato cultivars due to P fertilization had also been reported by Dyson and Watson (1971) and Jenkins and Ali (1999). On the other hand, a reduction in the TB or growth rate under P deficient conditions had also previously been described (Dechassa et al 2003: Covarrubias-Ramírez 2005Zelalem, et al 2009;Fleisher et al 2013) and attributed to a limited amount of photosynthetically active radiation being absorbed (Colomb et al 1995) and/or to a less efficient conversion of the intercepted radiation (Plénet et al 2000).…”

Plant diagnostic methods to determine P deficiencies need the definition of a critical concentration value which represents the minimum P concentration required to achieve maximum growth. The critical P concentration (Pc) has not been determined for potato. We designed a five years experiment with the objective of using the relationship between P concentrations and total dry matter (TB) yield to determine and validated the Pc, expressed as a function of TB. The Pc was described by the model: 3.919*TB -0.304 where total biomass (TB) ranged from 1 to 16 Mg ha −1 . The P nutritional index (PNI), which is the ratio between the measured whole plant P concentration and Pc, was associated with the relative tuber yield measured at harvest. The results from this study support the use of PNI from 60 to 80 days after planting to determine potato crop P nutritional status.Resumen Los métodos de diagnóstico en plantas para determinar las deficiencias en P necesitan la definición de un valor de concentración crítica, el cual representa la concentración mínima de P requerida para alcanzar el máximo crecimiento. La concentración crítica de P (Pc) no ha sido determinada para papa. Nosotros diseñamos un experimento de cinco años con el objetivo de utilizar la relación entre las concentraciones de P y el peso total del rendimiento de materia seca (TB) para determinar y validar la Pc, expresada como una función de TB. Se describió a la Pc por el modelo: 3.919*TB -0.304, en donde la biomasa total (TB) fluctuó de 1 a 16 Mg ha −1 . El índice nutricional de P (PNI), que es la proporción entre la medida de la concentración de P de la planta completa y la Pc, se asoció con el rendimiento relativo de tubérculo, cuantificado a la cosecha. Los resultados de este estudio respaldan el uso de PNI de 60 a 80 días después de la siembra para determinar el estatus nutricional del P del cultivo de papa.
