| Resumo: | There is much information on the adequate soil water matrix potential for returning irrigation in conventional soil tillage systems; however there is not enough information on the best soil water matrix potential for no-tillage production systems. This work aimed to study the effect of five irrigation levels on yield, soluble solids, and fruit acidity of the Hypeel tomato, cultivated for industrial processing and cropped on no-tillage system in Yellow Latosol. The experiment was carried out on a randomized block design with five treatments and four replications. The treatments consisted in different soil water matrix potentials for returning irrigation (m at 13cm of soil depth): -15, -30, -45, -60 and -75 kPa. The results obtained showed that the soil water matrix potential of -28.5 kPa resulted in maximum yields for tomato crop; whereas the value of -50.8 kPa resulted in the maximum fruit soluble solids concentration. |
