Abstract
This study based on cross sectional data of 94 oyster mushroom farms in Quang Tri province to measure their technical efficiencies at farm level and identify the impact of attending training course variable on it by using two stage Bootstrapped Data Envelopment Analysis. The empirical results confirm that attending training course is an important factor impact on technical efficiency of oyster mushroom farm in study area. The farms used to attend a relevant training course were more efficient than farms did not. Moreover, it also shows that gender of the farmer, gender of the farmer, source of irrigation water, duration of oyster mushroom production and number of oyster mushroom crops cultivated on this current farm also had significantly relationship with technical efficiency. Comparing to the best practice farms in this sample, the oyster mushroom farms in study area should use fewer inputs to produce the current level of output to be efficient. Especially, farmers should attend the relevant training course and local authority should organize more training course to improve current level of efficiency of those farms. Moreover, the impacts of gender of the farmer, source of irrigation water, duration of production and number of crops should also be included in the content of those up-coming training courses.References
