The increase in food production through innovative seed management practices is an option. Three seed sizes (big, small and control – any size), two planting positions (flat and slant) and their interactive effects on the growth and yield of fluted pumpkin (Telfairia occidentalis Hook. f.) were assessed. There was a significant (p<0.05) effect of seed size and planting position and an interaction between seed size and planting position on the emergence, vine length and fresh marketable weight (yield) of fluted pumpkin. The seed emergence increased significantly (F2,6 = 16.82, p<0.01) only when the seeds were slanted at planting and ranged from 72.2 % to 100 %. The same trend was observed across the two planting positions for the small seeds with the highest (100 %) recorded in (small x flat and big x slant) and the lowest (72.2 %) recorded in (small x slant). At 11 weeks after sowing the shortest vine length (135.83 cm) was observed on the small seed sizes slanted at planting and the longest when small seeds were planted flat. Additionally, there was a significant (p < 0.01) interaction between seed size and planting position on the yield which increased significantly only when the seeds were slanted at planting, but not for seeds planted in the flat position. At 11 weeks after sowing, the fresh marketable yield ranged from 0.49 t.ha-1 for slant x small – 0.71 t.ha-1 for flat x small and slant x big respectively. Overall, planting fluted pumpkin seeds in the flat position can improve emergence, growth and fresh marketable yield.
