This trial was done with the main objetive of evaluating the productive behavior of four treatments termed systems of conduction for the melon crops cultivated inside polyethylene greenhouse. The four systems of conduction or treatments had the following composition: system 1, one stem with ramification without pruning; 2, one stem without ramifications with pruning; 3, two stems with pruning and 4, four stems with pruning. Results showed the conduction system 3 as the best for melon crop, followed by treatments 1 and 2. The highest melon productivity per square meter 9.4kg was given by the treatment 3. The adoption of the pruning technique improved median weight of the melon fruit. Treatment 4, reduced the number of fruits per plant and the medium size of the fruits. Also, the negative effect of the treatments 3 and 4 regard to delay in fruit mature and harvest were observed.
