Field and pot studies were conducted at the University of Ghana, Legon to assess the effects of heading
back and spacing on the yield and yield components of two okra cultivars: Legon Fingers and Legon
Spineless. Pruning treatments comprised Pruning at 35 days after germination (DAG), Pruning at 40
DAG, Pruning at 45 DAG and No pruning (Control) in both studies. Spacing treatments were 60cm x
40cm (Control) and 60cm x 60cm in the field studies. The results revealed that heading back enhanced
the production of more pods per plant, enhanced weight of pods per plant and increased total yield and
marketable yield and reduced pod length, pod diameter and pod weight. Heading back also shortened
the length of harvest duration and the number of harvests per plant in both studies. In all, pruning at 35
DAG better enhanced yield compared to the control and the subsequent prunings. Pruning increased
total yield (t/ha) by 2.2 to 53.4% in the field studies and increased yield/plant by 3.9 to 21.3% in the pot
studies. Wide spacing (60cm x 60cm) enhanced okra yield/plant but reduced total yield when compared
to the control spacing of 60cm x 40cm in the field studies. Legon Fingers produced longer pods than
Legon Spineless while Legon Spineless produced thicker and heavier pods than Legon Fingers.
