A field experiment was carried out at research farm of Rampur Campus, Khairahani, Chitwan, Nepal to investigate the combined effect of different spacing and seed/stand on the growth and yield of okra (Abelmoschus esculentus).The experiment was laid in randomized complete block design (RCBD) with five treatment combinations, including Broadcasting, 50*30 cm spacing + single seed/stand, 50*30 cm spacing + double seed/stand, 40*20 cm spacing + single seed/stand and 40*20 cm spacing + double seed/stand. Phenological parameters, biometrical parameters, and yield attributes were assessed, revealing noteworthy findings. The finding revealed that treatment 2 (50*30 cm spacing + single seed/stand) consistently outperformed other treatments across multiple parameters, resulting in early (38.25 DAS) flowering, highest number of branches (3) and leaves (21.12) per plant, the highest (197.6 cm2) leaf canopy, a wider (12.22mm) stem diameter, highest (17.3) number of fruits per plant, and the highest (282.9gm) fruit yield per plant. In contrast, treatment 1 (Broadcasting) consistently exhibited the poorest performance across all parameters. Treatment 5 (40*20 cm spacing double seed/stand) demonstrated the highest (25.54 tons/hectare) total yield per hectare. While plant height, fruit length, and fruit diameter showed nonsignificant differences during statistical analysis. This finding suggests that a combination of 50*30cm spacing and a single seed /stand can be used to substantially boost okra yields and growth performance.
