A study was carried out to investigate the effect of original strengths of honey bee colonies and methods of supering on honey production from A. mellifera bees in Terai, Nepal. Three different supering methods were studied in colonies covering originally 5, 10 and 20 combs of bees. Colony prepared initially from 5 combs of bees as farmers’ practices produced significantly the lowest amount of honey (30.1 kg per year) with the production of the lowest number of worker brood and foragers. Honey bees produced significantly the higher amount of honey in 10-comb colony with deep super (62.2 kg per year) than in shallow super (47.5 kg per year) and in 5-comb colony without super. The supering colony originally with 20 combs of bees in deep super produced highest honey yield (74.5 kg per year) followed by the same strength of colony in shallow super (68.8 kg per year) by producing more number of worker brood and foragers. Production of honey in colonies covering originally 20 and 10 combs was higher in winter (30.2 and 18.9kg per colony) than in spring (24.7 and 18.7kg per colony) and autumn (16.7 and 10.2kg per colony).Colony prepared initially from 10 combs of bees in a single brood chamber with a deep super produced the higher cost effective honey with a benefit cost ratio of 1.52:1 then other methods evaluated. Number of swarming queen cells was the highest (2.9 per observation) in spring when colony was initiated originally with 10 combs of bees without super and minimum (0.4 per observation) in colony of 10 combs of bees with deep super. Honey production was highly and positively correlated to the number of worker brood, pollen store and foragers.
