Giant garlic var. Ampelo is considered as an alternative crop in Sonora, Mexico. With the main objective to get better quality and promote maturity this study was performed in Costa de Hermosillo. Clove planting was in October 2007, with  population  a density of  50,000 plants per hectare. A randomized complete block design was used with  three stem cuts: 20 cms, 40 cms  just at the moment of the  stem presence, and a control.
The best treatment was with cutting at the 40 cms. Yielding an average of 20.21 tonha^-1 . and a bulb diameter of 79.6 mm. The second best treatment  was at the moment of   stem presence with 18.86 tonha^-1. and a bulb diameter of  78.7 mm . Cutting at 20 cms. yield 18.54 tonha^-1.  and bulb diameter of 77.6. There no was  significative differences among tratments. Control  got  lowest yield with 17.29 tonha^-1.  and a bulb diameter of 73.7 mm  showing a significative differences with other treatments.  results indicate the stem cutting at 20, 40 cms and at stem presence can improve Quality and yield  in Ampelo giant garlic growing in Sonora, Mexico.
