| Tóm tắt: | The study aims to determine the technical efficiency and
factors affecting the technical efficiency of lettuce farmers in Dalat
City. The study’s primary data were collected by surveying
structured questionnaires from 100 lettuce farmers in Dalat City. The
Cobb-Douglas production, combined with the technical inefficiency
according to the one-stage estimation method, was estimated by the
program Frontier 4.1. The calculated results illustrate that the
average technical efficiency of lettuce farmers is 0.76; with the usage
level of available inputs and present techniques, Dalat lettuce
production in the rainy season may increase by 24%. Besides, the
study has also indicated that factors such as lettuce cultivated area,
number of seedlings, and amount of pure potassium fertilizer
positively influence lettuce yield. In contrast, the amount of pure
nitrogen fertilizer negatively affected lettuce output. However, the
education level and experience of household heads in lettuce
cultivation positively affected technical efficiency. Therefore, to
improve lettuce productivity and technical efficiency in Dalat City,
the study suggests that farmers need to increase the amount of
potassium fertilizer and reduce nitrogen fertilizer. In addition, state
agencies recommend teaching lettuce farmers about the balanced
and reasonable application of N, P, and K fertilizers through
documents or training courses. |
