Abstract:

The effects of surface (SDI) and subsurface (SSDI) methods of drip irrigation were investigated on the growth, water use efficiency (WUE), fruit yield and quality of bell pepper (Capsicum annuum) cv. 11B 14 grown in Harran Plain, Turkey, during 1999-2000. Four irrigation levels based on Class-1-Pan evaporation, i.e. water-stressed (A) and unstressed (B, C and D), were applied to plants every other day at 4 different growing periods, i.e. between transplanting of seedlings to the field and 50% flowering; between flowering and 50% fruit formation; between fruit formation and beginning of harvest; and between the beginning of harvest and at the end of harvest. Water-stressed treatment using SDI reduced all parameters compared with the unstressed treatments. The highest yield of 50.8 and 55.2 tonnes/ha for SDI and SSDI, respectively, was obtained from treatment D. The SSDI+A treatment had the highest WUE and was significantly better than the SDI+D treatment. Seasonal water use ranged from 715 to 1412 mm in SDI and 765 to 1475 mm in SSDI. There was no significant yield changes between C and D irrigation levels under both irrigation systems. The results indicate that SSDI relatively mitigates the negative effects of water stress on the growth and fruit yield of field-grown bell pepper, particularly in semiarid regions with limited water resources.
