A study was conducted with watermelon during the spring-summer cycle of 1999 in Durango, Mexico. Water productivity and yield were measured as quantity of fruits produced per unit of water consumed in plots established by direct sowing (DS) or transplant (with 2 true leaves (HV) or transplant at initial guides (IG)), with or without plastic mulch, and irrigated considering 2 irrigation criteria (to replace the equivalent of 50% (50 E) or 60% (60 E) of the mean daily evaporation) using underground drip irrigation. Establishing the crop by transplanting at initial handlebar (IG) or HV stages, with plastic mulch, and irrigated at 50% E, recorded productivity of 9.0 and 9.1 kg/m3, respectively. In contrast, the crop established by DS, without mulch, and irrigated at 50% E had a water productivity of 4.0 kg/m3. The highest fruit yields of 51.98 and 51.51 t/ha were obtained in plots established with HV and IG, respectively, with mulch, and irrigated at 60% E. The lowest yield (22.7 t/ha) was obtained in plots established by DS, no mulch, and irrigated at 60% E. Plastic mulch allowed harvest to begin 7 days earlier than the control treatments. Using transplant at IG allowed harvest to begin 7-14 days earlier than transplant at HV or DS, and 22 days earlier than treatments with DS and no plastic mulch.
