Productivity and quality of tomato submitted to irrigation levels using mulching in economic beds

The objective of this study was to evaluate irrigation levels in tomato crops, using economical beds with mulch. A randomized block design within a split-plot had run 2 x 5 factorial treatment scheme structure, four replications. plots were the five (50, 75, 100, 125, and 150%) crop Evapotranspiration (ETc), subplots two varieties RASTEIRO RIO GRANDE (RR) (Lycopersicon lycopersicum) CALINE IPA- 7 (IPA) esculentum Mill.). In end, 40 experimental units consisting plants each evaluated. variables assessed productivity (PROD), fruit mass (FM), volume (VOL), diameter (DIA), titratable acidity (TA), hydrogen potential (pH), soluble solids (° Brix), solids/titratable ratio (SS/AT). results showed that level 117.85% ETc provide greater for cultivar GRANDE, while IPA-7, it 150% ETc. variety IPA-7 higher content lower ratio. addition influenced decrease by applying up 125%
