Production of eggplant and pepper yields under surface and subsurface drip irrigation systems in sandy soil [electronic resource].

Includes references.

Two different drip irrigation systems (surface and subsurface systems); four irrigation rates and tWo emitter spacings were considered in respect to the production of eggplant and pepper in sandy soil. The highest early yield of eggplant and pepper increased with increasing the irrigation rate under subsurface built in dripline (SSGR) compared with surface on line dripper (SD) and surface built in dripline (SGR). The highest early yield of eggplant and pepper of 1.77 and 1.53 kg/m2 were remarked at 0.3m emitter spacing under SSGRT4, but the lowest values were 0.7 and 0.64 kg/m2 at 0.5 m emitter spacing under SGRT1. Plant production and mass per fruit of eggplant and pepper increased by increasing emitter spacings in the same row from 0.3 to 0.5 m and irrigation rates from T1 (509 and 569 mm/season) to T4(815 and 911 mm/season). The highest total yield of eggplant and pepper were 13.63 and 13.17 ton/fed. at 0.3m emitter spacing under SDT3. At the minimum irrigation rates (509 and 569mm), the total yield (eggplant and pepper) increased atSSGR (8.12 and 6.86 ton/fed.) compared with SGR (7.56 and 6.3 ton /fed.) and SD (7.28 and 6.56 ton/fed.) SGR.
