“…In a previous study, the inclusion of canola green manure in potato rotations was associated with higher tuber weights compared to fallow (Wiggins and Kinkel 2005). In a more recent study, however, Griffin et al (2009) found no effect of a winter rapeseed cover crop on total tuber yield or marketable tubers in a potato-barley rotation.…”

The productivity of potato (Solanum tuberosum L.) systems may be strongly influenced by rotation. A field study consisting of six rotations (potato with canola (PC), wheat (PW), canola-wheat (PCW), oat-wheat (POW), wheat-canola-wheat (PWCW), and canola underseeded to alfalfa-alfalfa-alfalfa (PCAA)) arranged as an RCBD was established on a clay loam in Manitoba, Canada in 1998 and monitored for twelve years to determine effects on potato yield and quality. Higher yields for canola-containing rotations were evident in three years (P<0.10), but not beyond 2005. From 2007 onward, 2-year rotations produced a markedly lower yield than other rotations. Yields of 3-and 4-year rotations were similar, although PCW and PCAA were most frequently among the higher-yielding rotations. Overall, PC had a lower specific gravity than other rotations. Results suggest 3-and 4-year rotations, particularly PCW and PCAA, helped maintain productivity. Two-year rotations of PC and PW were not sustainable due to declining yields.Resumen La productividad de los sistemas de papa (Solanum tuberosum L.) pueden estar fuertemente influenciados por la rotación. Se estableció un estudio de campo consistente en seis rotaciones; papa con canola (PC), con trigo (PW), con canola-trigo (PCW), con avena trigo (POW), con trigo, canola, trigo (PWCW), y con canola mezclada con alfalfa-alfalfa-alfalfa (PCAA), arreglado en un diseño experimental de bloques completos al azar, en un suelo franco-arcilloso en Manitoba, Canadá, en 1998, y monitoreado por doce años, para determinar los efectos en rendimiento y calidad de la papa. Se hicieron evidentes más altos rendimientos en las rotaciones que incluían a la canola en tres años (P<0.10), pero no más allá de 2005. A partir de 2007, las rotaciones de dos años produjeron un rendimiento más bajo bien marcado que en otras rotaciones. Los rendimientos de rotaciones de 3 y 4 años fueron similares, aunque PCW y PCAA estuvieron entre las más frecuentes de las rotaciones de mayores rendimientos. En general, PC tuvieron gravedad específica más baja que otras rotaciones. Los resultados sugieren que rotaciones de 3 a 4 años, particularmente PCW y PCAA, ayudaron a mantener la productividad. Rotaciones de dos años de PC y PW no fueron sostenibles debido a la disminución en rendimientos.

“…Organic and conventional producers often plant cover crops to fix nitrogen, improve water infiltration, suppress diseases and nematodes, prevent soil erosion, add organic matter to the soil, and reclaim nutrients (Clark 2007;Griffin et al 2009). Barley (Hordeum vulgare), sudangrass (Sorghum bicolor), and buckwheat (Fagopyrum esculentum), can suppress weeds through their rapid emergence and growth, shading out weeds and competing for water and nutrients.…”

Managing weeds without herbicides requires an integration of methods and strategies and a change in how weeds are perceived. Weeds should be managed in a holistic, intentional and proactive manner. Understanding the interactions between the cropping system and the weed community and managing the cropping system to prevent and discourage weeds and maintain a low weed seedbank is necessary for successful weed management in organic systems. Cultural practices, including a well-planned crop rotation, planting cover crops, sanitation practices, and optimum row spacing and timing of planting are important aspects of managing weeds in organic systems. Multiple, well timed shallow cultivations or flaming can eliminate many early season weeds. Once emerged, many crops are fast growing and produce a canopy able to suppress weeds. New technologies for detecting crop rows and weeds coupled with precision cultivation, flaming, and application of nonselective organic herbicides are being developed and hold promise to reduce the need for hand weeding.Resumen El manejo de malezas sin herbicidas requiere una integración de métodos y estrategias y un cambio en la manera como se perciben las malezas. Éstas deben manejarse de una manera holística, intencional y proactiva. Es necesario un entendimiento de las interacciones entre el sistema de cultivo y la comunidad de malezas y del manejo del sistema de cultivo, para prevenir y dificultar a la maleza y mantener un bajo banco de semillas harvenses para un manejo exitoso de las malezas en sistemas orgánicos. Las prácticas culturales, incluyendo una rotación de cultivos bien planeada, plantando cultivos de cobertura, prácticas sanitarias, y un óptimo espaciamiento entre surcos y fechas de siembra, son aspectos importantes para el manejo de malezas en sistemas orgánicos. Escardas múltiples, superficiales y bien programadas, o flameo, pueden eliminar muchas malezas tempranas. Una vez emergidos, muchos cultivos son de rápido crecimiento y producen un follaje capaz de suprimir a las malezas. Se han estado desarrollando nuevas tecnologías para detectar los surcos del cultivo y las hierbas juntas con cultivos de precisión, flameo, y la aplicación de herbicidas orgánicos no selectivos, y son prometedoras para reducir la necesidad de deshierbes manuales.

“…to soil are well recognized. In potato systems, these amendments increase soil carbon and nitrogen, improve soil structural characteristics, improve moisture-holding capacity, and may confer disease-suppressive advantages [3][4][5][6][7][8][9]. These attributes may be especially appealing to producers with limited water and/or degraded soil resources.…”

Potato productivity in the northeastern US has been relatively constant for over 50 years, raising questions about what factors are limiting productivity. Research was initiated in 2004 to identify key constraints to potato productivity by evaluating Status Quo (SQ), Soil Conserving (SC), and Soil Improving (SI) cropping systems under both rainfed and irrigated management, and it was found that addition of compost or irrigation substantially increased yield. In this study, we employed partial budgeting to determine cost differences and their impact on net revenue for these cropping systems. Differences in systems were primarily associated with rotation length, tillage operations, compost and application expenses, and water management practices. When compost (as composted dairy manure) was annually applied at 19 Mg·ha −1 and evaluated over the entire 3-year crop rotation cycle, the compost-amended rainfed SI system was more expensive to maintain than the irrigated SC system if compost cost exceeded $3.63 Mg . Average marketable yields were used to calculate gross and net revenue for each system. Because average potato yield for the irrigated SQ system (28.4 Mg·ha ), we were able to compare cost of irrigation versus compost for achieving comparable yield. The compost-amended SI system under rainfed management generated more net revenue from the potato crop than the irrigated SQ system when compost costs were less than $7.42 Mg . When compared to the commonly used rainfed SQ system, rainfed SI achieved higher net revenue as long as compost cost was less than $22.95 Mg . The rainfed SI system achieved higher net revenue than the irrigated SC system when compost cost was $9.43 Mg −1 or less, but generated greater net revenue than the rainfed SC system regardless of compost costs, due to substantially higher yields associated with compost amendment. This investigation demonstrates that compost is a potentially viable substitute to irrigation for potato in the northeastern US; however, such potential is highly dependent on suitable compost sources and application costs.
