Evaluation of the morphometric characteristics of melon under different irrigation management - DOI: 10.7127/rbai.v1801365

Resumo

The work aims to evaluate different irrigation management on the morphometric characteristics of melon. Planting was carried out in a lot located in DIBAU, in the municipality of Marco-CE. The hybrid Goldex F1 was cultivated, spacing 0.3 m between plants and 2.0 m between rows. The experimental design was the DBC with five irrigation managements, M1, M2, M3, M4 and M5 in four blocks. The following variables were evaluated: plant dry mass (DM), marketable fruit mass (MF), fruit length (CF), fruit diameter (DF), leaf area (AF) and °Brix. The results show that even with twice the water depth applied between some managements, no significant difference was observed between the analyzed variables, possibly due to the high permeability of the soils under study, which did not allow waterlogging in the management with higher depths. The managements with smaller depths to plants did not suffer water deficit due to the irrigation frequency, three times a day. It is concluded that with the application of management M1 and M2, it is possible to obtain the same productivity and quality of fruits using less than half of the water used in the other managements.
