“…The tuber dry matter increased from 0 to 180 kg N ha -1 with increase in N fertilization. Thereafter the differences were not significant (Table 4), which is consistent with other findings (Lauer 1986;Westermann et al 1994b;Joern and Vitosh 1995). Specific gravity was higher for cv.…”

A field study was conducted during 2000-2001 and 2001-2002 at the Central Potato Research Institute Campus, Modipuram, India, in order to increasing the processing-grade tuber yield of India's first ever developed processing potato cultivars, Kufri Chipsona-1 and Kufri Chipsona-2. Tuber yield and post-harvest quality characteristics were evaluated in response to five N levels (0, 90, 180, 270 and 360 kg N ha -1 ). The crop growth traits (stem number, plant height and compound leaf number) responded positively to N application, whereas the effect of N fertilization on processing-grade tuber number, total tuber number per ha and tuber number per plant was quadratic. There was a steady increase in tuber weight per plant, processing-grade tuber yield, total tuber yield and biomass yield in response to N application. Kufri Chipsona-1 produced a 23.6% higher tuber yield per plant than Kufri Chipsona-2. Agronomic N use efficiency decreased linearly with increased N doses. Specific gravity and tuber dry matter percentage responded positively to N application, while crisps colour (at harvest and after storage) and reducing sugars remained unaffected. Cultivar was the major factor that influenced the tuber quality parameters (specific gravity, crisps colour). Higher values of these quality traits were observed in Kufri Chipsona-2 as compared to Kufri Chipsona-1. Net income and benefit cost ratio (B:C) indicated that Chipsona cultivars should be fertilized with 270 kg N ha -1 for realizing higher processing-grade yields and desirable quality tubers.

“…The effects of minimizing N application rates at planting on NO 3 leaching are more dramatic when leaching rainfall occurs early in the season (Errebhi et al 1998a). A study on an irrigated sandy soil of Michigan has shown that acceptable tuber yield can be obtained with lower rates of N than currently applied by the growers with the potential for reduction in NO 3 leaching (Joern and Vitosh 1995). For example, reducing N application rates from 260 to 170 kg ha −1 for Russet Burbank potato reduced NO 3 leaching from 200 to 120 kg ha −1 .…”

Strategies to Reduce Nitrate Leaching into Groundwater in Potato Grown in Sandy Soils: Case Study from North Central USA

There is increasing public concern to reduce nitrate pollution to groundwater, especially in sandy soils. Strategies to reduce nitrate leaching are developed to increase N use efficiency, reduce groundwater pollution, and increase tuber yield. A growing interest in N management should consider management strategies for N supply, soil moisture for transport, and crop N demand that are economical and compatible with local production systems. We present a review of the literature on conventional and innovative strategies for N, irrigation, and crop management for potato production in reducing N leaching in sandy soils. The amount of fertilizer-N should be decided based on an integrated evaluation of soil organic matter content, soil texture, residual soil N, crop residues, credit to organic N sources, crops to be grown including varieties and crop physiological needs, cropping systems, yield potential, water management, and N concentrations in irrigation water. Research advances have no quick fix for controlling NO 3 leaching to groundwater. However, the best combination of proven strategies can reduce leaching potential significantly.Resumen Existe una preocupación pública en aumento para reducir la contaminación de nitrato en el agua del subsuelo, especialmente en suelos arenosos. Se han desarrollado estrategias para reducir la lixiviación de nitratos para aumentar el uso eficiente de N, reducir la contaminación del agua del subsuelo, y para aumentar el rendimiento de tubérculo. Un interés en aumento en manejo de N debería de considerar estrategias de manejo para suministro de N, humedad del suelo para el transporte, y demanda de N del cultivo que sean económicas y compatibles con los sistemas locales de producción. Presentamos una revisión de la literatura en las estrategias convencionales e innovativas para el manejo de N, riego y del cultivo para producción de papa en la reducción de la lixiviación de N en suelos arenosos. La cantidad del fertilizante nitrogenado deberá decidirse con base a una evaluación integrada del contenido de materia orgánica en el suelo, textura, N residual, residuos de cosecha, reconocimiento a las fuentes de N orgánico, cultivos a sembrarse incluyendo variedades y necesidades fisiológicas del cultivo, sistemas de cultivo, potencial de rendimiento, manejo del agua, y concentraciones de N en el agua de riego. Los avances en investigación no tienen un remedio rápido para controlar la lixiviación de NO3 al agua del subsuelo. No obstante, la mejor combinación de estrategias probadas pueden reducir significativamente el potencial de lixiviación.

“…Em países com clima temperado, os trabalhos têm mostrado aumento na produção de MS, com o aumento da dose de nitrogênio (Guasena & Harris, 1968;Westermann & Kleinkopf, 1985;Joern & Vitosh, 1995;Meyer & Marcum, 1998;Errebhi et al, 1998), porém quantidades excessivas de nitrogênio estimulam o crescimento vegetativo e atrasam a formação e a maturação dos tubérculos e, os tubérculos imaturos colhidos apresentam uma menor quantidade de MS e podem apresentar uma qualidade ruim (Kleinkopf et al, 1979;Roberts & Dole, 1985;Harris, 1992).…”
