Seed yield, crude protein and mineral nutrient contents of sesame during a two-year continuous cropping on upland field converted from a paddy

Sesame (Sesamum indicum L.) is an important oilseed crop that is negatively affected by continuous cropping but there is still limited research on this phenomenon. A three-year field experiment was conducted from 2012 to 2014 at Tottori, Japan, on an upland field converted from a paddy to determine the effect of continuous cropping on seed yield, crude protein and mineral nutrient contents of four sesame cultivars (‘Maruhime’, ‘Nishikimaru’,...
