Study on seed development and maturation revealed that optimum stage of physiological maturity was attained at 42 DAA and 35 DAA in foxtail and little millet, respectively which was accompanied by maximum length and breadth of panicle, fresh and dry weight accumulation in panicle and seeds, 1000 seed weight, enzyme activities and nutrient accumulation such as α-amylase content, dehydrogenase activity, carbohydrate content, calcium content and phosphorus content with decreased moisture content in panicle and seeds.
