in order to study the effects of fall planting dates on yield and yield components of six cumin (cuminum cyminum l.) ecotypes an experiment was arranged in a randomized complete block design as a split-plot with three replications during 2007-08 growing season at the agricultural research station of ferdowsi university of mashhad. three planting dates (18 oct. (first), 8 nov. (second) and 29 de...

In order to elucidate the effect of sowing date on oilseed rape (Brassica napus L.) yield and yield components, three varieties including Tower, Rafal and Global were sown from November 7 to December 22, 1998-99 in four dates with 15day intervals in Dezful region. A split-plot design based on randomized complete blocks with four replications was used in which levels of sowing dates and cultivar...
