The use of chemical fertilizers are increasing yearly in Bhutan contributing to environmental pollution and human health hazard. The use of bio-fertilizers such as multiplex Annapurna and spic subrabi are not much familiar to the famers due to lack of less information on its effectiveness in crop yield and nutrients contain. A field experiment was carried out to compare the effects of different fertilizers on growth and yield of okra (Abelmoschus esculentus L.). The randomized complete block design experiment had five treatments with four replications. Besides a control, the experiment included bio-fertilizer Multiplex Annapurna, bio-fertilizer Spic Surabi, farm yard manure (FYM), and chemical fertilizer (NPK) treatments. Bio-fertilizers were applied at the rate of 297kg/ha while FYM and NPK chemical fertilizers were applied at the rate of 4,000 kg/ha and 100:150:50 kg/ha respectively. Plant height, stem diameter, plant canopy, and number of leaves were measured at 42, 54, 66, and 78 days after sowing (DAS). Yield and yield components (number of fruits per plants, fruit length, and fruit weights) were assessed at the time of harvest. Fertilizer treatment had a significant effect on growth and yield of okra (p < .05). Spic Surabi gave the highest yield (11.77 t ha-1) and the lowest (9.63 t ha-1) was from control treatment. The results indicated that the application of bio-fertilizer, mainly Spic Surabi, increases growth and yield of okra.
