“…This was also apparent at the second evaluation, but only in 1997. The greater amount of plant vegetative growth with early N application is consistent with results from several others (Ivins and Bremner 1965;Benepal 1967;Grewal et al 1979;Kleinkopf et al 1981;Vos 1995), who showed earlier tuberization and larger early-season allocation of carbohydrates to the tubers when N supply is low. The treatment effect on tuber number is less consistent in the literature as some researchers have also noted fewer tubers where N was applied (Sommerfeldt and Knutson 1968;Clutterbuck and Simpson 1978), whereas others observed tuber number increases (Hanley et al 1965;Dubetz and Bole 1975;Roberts et al 1982;Belanger et al 2002) or no change (Benepal 1967;Dyson and Watson 1971;De la Morena et al 1994) in tuber number with increasing N application rate.…”

“…Overall, results from this experiment confirms the work of others that showed the need for an adequate amount of N sufficiently early in the season to set up the crop vegetatively to produce high yields (Ivins and Bremner 1965;Kleinkopf et al 1981;Roberts et al 1982;Westermann and Kleinkopf 1985). While applying some N at this time clearly delays tuberization, and in some cases appears to reduce tuber number and has the potential to increase N leaching, this infusion of early N seems to be required for the crop to attain its yield potential.…”

“…In early-season N-deficient situations, Ivins and Bremner (1965) showed that plant shoot growth is reduced, and carbohydrates that would typically be used for producing leaves are shifted toward tuber initiation. Conversely, many researchers have observed that an adequate supply of early-season N results in increased vegetative lateral branching, leaf number, leaf size, and leaf area index (Benepal 1967;Westermann and Kleinkopf 1985;Millard and Mackerron 1986;Millard and Robinson 1990;Vos 1995;Vos and van der Putten 1998).…”

Importance of Early-Season Nitrogen Rate and Placement to Russet Burbank Potatoes

Early-season nitrogen (N) is necessary for optimal potato vegetative growth and creating an optimal growing condition for high yields; however, on sandy soils it also increases the risk of losing fertilizer N through leaching. This 3-year field experiment evaluated whether a smaller amount of N placed near the plant roots could provide the benefits associated with higher rates of early N applications that were less well placed. Two rates of N applied at emergence (40 or 80 kg N ha −1 ) were spot-placed (5 to 7 cm around each plant), banded along the row, or broadcast applied, and compared to no N or where all of the in-season N was applied at tuberization. All plots except the zero N controls received a total of 170 kg ha −1 of in-season N. Where emergence N was spot-applied in some years, tuber numbers were reduced compared to where the N was broadcast, and in these situations, resulted in increased tuber size and higher yields of primesized tubers (U.S. No. 1, 170 to 370 g). Where differences existed, results from banded treatments were intermediate between those from the spot and broadcast treatments. However, in spite of apparent N placement effects likely associated with having a higher concentration of N near the plant roots early in the season, no differences were evident between the two rates of emergence N within a given placement. In this experiment, total yields were not affected by rate or placement of emergence N. Overall, this experiment provides support for the concept of placing early-season N near the plant roots, and band applications along the row may be a grower-manageable alternative for achieving this goal.Resumen El nitrógeno (N) al inicio del ciclo es necesario para el crecimiento vegetativo óptimo de la papa y para generar una condición óptima de crecimiento para altos rendimientos; no obstante, en suelos arenosos también se aumenta el riesgo de pérdida de fertilizante nitrogenado por lixiviación. En este experimento de campo de tres años se evaluó si una cantidad menor de N ubicada cerca de las raíces de la planta pudiera suministrar los beneficios asociados con niveles más altos de aplicaciones tempranas de N que no estuvieran tan bien ubicadas. Se aplicaron dos niveles de N a la emergencia en manchones (40 u 80 kg N ha −1 , 5 a 7 cm alrededor de cada planta), en banda a lo largo del surco, o disperso, y se compararon con ausencia de N, o cuando todo el N del ciclo se aplicó a la tuberización. Todos los lotes, con excepción de los testigos de cero N, recibieron un total de 170 kg ha −1 de N en el ciclo. Cuando se aplicó el N en manchones a la emergencia, en algunos años, se redujo el número de tubérculos en comparación a cuando se aplicó disperso, y en estas situaciones, resultó en el aumento en el tamaño del tubérculo y en rendimientos más altos de tubérculos de tamaño de primera (U.S. No. 1, 170 a 370 g). En donde hubo diferencias, los resultados de los tratamientos en banda fueron intermedios entre los de manchones y los dispersos. No obstante, a pesar de los efectos aparentes de la ...

“…3). Also, tuber initiation makes diversion of assimilates to tuber, thus early tuber initiations cause small plants and leaf area leading to lower final yield (Ivins and Bremner, 1965;Bremner and Radley, 1966). Therefore, environmental conditions during the early growth (before tuber initiation and early tuber growth phase) may play crucial role for the late tuber growth.…”

“…The increase in weight of a crop of potato tubers is usually a linear function of time when growing conditions remain constant (Beukema and van der Zaag 1990), with the rate of increase being relatively insensitive to environmental changes other than the supply of water (Moorby 1968). N supply influences both yield-determining factors, the bulking rate and the period of time of tuber growth (Ivins and Bremner 1965;Honeycutt et al 1996).…”

For organic potato producers, the two main challenges are disease and nutrient management. Both are limited by regulations that on the one hand prohibit the use of chemical fertilizers, especially nitrogen, and on the other hand prohibit most synthetic pesticides. Late blight caused by Phytophthora infestans is commonly thought to be the most yield-reducing factor. However, because there is no really effective fungicide available to control late blight, there are virtually no yield loss data available for organic farming conditions. In this paper, the state of the art of organic potato tuber growth under on-farm conditions with respect to disease and nutrient management is summarized by field trials and on-farm surveys on commercial organic crops carried out in the years 1995-1998. Soil nitrogen (N) levels, plant N uptake, disease development of P. infestans and potato yield were measured. Results indicated that N availability was most important in limiting yields in organic potato crops. From on-farm data, a model including disease development, growth duration of the crops until foliage decay and different parameters related to N status of the crop could explain 73% of the observed variation in yield. Only 25% of this variation in yield could be attributed to the influence of late blight. Differences in N availability explained 48%. In conclusion, several points emerged from the results. In organic farming, yields are mainly limited by nutrient availability in spring and early summer. The effects of late blight on yields may often be overestimated and cannot be deduced from results in conventional farming because of the strong interaction with nutrient status. Depending on N availability, tubers stop growing between mid-July (70-90 kg N ha −1 uptake), the end of July (110-140 kg N ha −1 uptake) and mid-August (140-180 kg N ha −1 uptake) due to N limitations. The higher the N status of a potato crop, the longer the growing period needed to achieve the attainable yield and the higher the probability that late blight stops further tuber growth and becomes the key tuber-yield-limiting factor. In the second part of this paper, the interactive effects of soil N availability and the impact of P. infestans on yield in the presence and absence of fungicides from 1996 to 1998 for mid-early main crops are reported. An empirical schematic model of disease impact depending on N availability was developed.
