Sesame Plant Bin Aims for Mechanized Harvest Breakthrough
Scientists in Venezuela pursue a sesame variety that ripens uniformly and keeps seeds in pods, aiding mechanical harvesting. A unique plant with cup upwards leaves and tightly closed pods shows promise, though curved styles and mottled leaves hindered early generations. Researchers expect further improvements for commercial viability.
