  1. Use crop rotation in potato farming systems

    A replicated, controlled trial in 2001-2002 at L'Assomption, Quebec, Canada (Dauphinais et al. 2005) found that density of root lesion nematode Pratylenchus penetrans (pest) was significantly higher after rotation of potatoes Solanum tuberosum with rye Secale cereale (8533 nematodes/kg soil) than after rotation with grain pearl millet Pennisetum glaucum (867 nematodes/kg soil) or continuous potato cultivar Superior (467 nematodes/kg soil). In the following growing season yields of potato cultivar Superior were lower in rye plots (10.8 tons/ha) than in grain pearl millet plots (24.1 tons/ha) or in continuous potato plots (21.8 tons/ha). Yields of potato cultivar Hilite Russet varied less between rotation crops. The experiment was carried out in four plots that had all grown potatoes in 2000. Each plot had one strip of each treatment. Strips were 10 x 80 m. Grain pearl millet was sown at 5.8 kg/ha with 230 kg/ha N in the form of 19-19-19 NPK fertilizer. Rye was sown at 120 kg/ha and potato planted at 2,313 kg/ha. In 2002 half of each strip was planted with each of the two potato varieties and yield was recorded. Nematodes were monitored twice each year using twelve 20 cm deep soil cores/strip.
