The findings of study presented that producing seasons of DaiLoan-mango growers has been three crops of year. The results showed that season 3 was the highest technical efficiency (73.10%), the second place was season 1 (62.65%), and then season 2 (58.41%). Moreover, the independent variables that explained technical efficiency of season 1 were the pesticide,  root fertiliser, leaf fertiliser and labour; season 2 were the root fertiliser, leaf fertiliser and labour; and in season 3 were the pesticide, root fertiliser, leaf fertiliser, and labour. Besides, important determinants of socioeconomic variables impacted positively on technical efficiency were the land area in all three season, market access in season 2, and credit access in season 3. However, the constraints to Dailoan-mango production were the farming experience in season 1, and the age in season 2. Based on these findings, policy makers should focus on effective inputs models that would boost technical efficiency through conducting regular workshops and orchard demonstrations on using input materials effectively for mango farmers. More so, farmers should be empowered in land area acquisition to applied advanced technology in large-scale production more effectively.
