The objective of this study was to determine the effects potassium fertilization (applied soil at 150, 250, and 350 kg K2O ha?1) irrigation on yield (fresh matter dry above-ground biomass tubers) health status tubers leaves three Jerusalem artichoke—JA (Helianthus tuberosus L.) cultivars (Topstar, Violette de Rennes, Waldspindel). Topstar cultivar characterized by highest total tuber (60.53 Mg ...

Preservation methods were evaluated forjerusalem artichokes (Helianthus tuberosus L.) to facilitate the back-up of field collections. In vitro plant cultures were established from field-harvested tubers for nine jerusalem artichoke cultivars obtained from the Plant Gene Resources of Canada, Saskatoon Research Center, Saskatoon, Canada. Most cultivars could be maintained at 5 °C or under 25°C gr...

Four bioagents i.e. yeast (Saccharomyces cerevisiae), Trichoderma viride, Bacillus subtilis, and Pseudomonas fluorescens in addition to humic acid, sulphated canola oil (sulphex 0.5%) and Paclobutrazol (PBZ) were applied to study their effect on disease incidence caused by Sclerotium rolfsii. Also, some vegetative parameters, tuber yield and enzymes activity of Jerusalem artichokes (Helianthus ...

The effect of photoperiod and growing degree days (GDD) on dry matter and dry matter partitioning in Jerusalem artichoke was investigated during 2008-09 and 2009-10. Three Jerusalem artichoke genotypes (CN-52867, JA-89 and HEL-65) were planted in 15 day-intervals between with thirteen different dates (September 20 to March 20) atKhon Kaen University,Thailand. Jerusalem artichoke genotypes ...
