Abstract:

An experiment was conducted toget vigorous seedlings through processing in Amaranthus polygonoides var. PLR 1 seeds. The seeds of Amaranthus polygonoides var. PLR 1 were subjected to specific gravity separation at different combinations of machine settings like vertical height (0.5,1,1.5), horizontal height (0.5, 1,1.5 cm), air flow rate (3,3.5 m3/hr) and deck oscillation speed (400,450,465 rpm). The seeds were separated into five grades from heaviest, heavy, medium, light, lightest weighed seeds as grade A, B, C, D, E respectively. The E grade represents the low weighed seeds and A grade represents the heavy weighed seeds. After grading the seeds are tested for its seed quality parameters like seed germination, shoot length, root length, dry matter, vigour index, 1000 seed weight, seed recovery percentage. The results revealed that the machine setting with 0.5 cm of vertical height, 1.5 cm of horizontal height, 3.5 m3/hr of air flow rate, and 465 rpm of deck oscillation speed recorded recovery percentage of 92% (grade A + grade B) with the highest 1000 seed weight and 83 % of germination and vigour index of 701.
