Technical and economical evaluation of tape drip and drip line irrigation systems in a strawberry greenhouse

Abstract

This study was done in a strawberry greenhouse to examine the technical and the economical evaluation of two drip irrigation systems including the tape and the drip line in the northern part of Iran. The result showed that all of the technical indices with tape were higher than drip line, and due to statistical analysis reveal a significant difference (P < 0.05). Yield and water productivity (WP) with tape were higher than drip line (P < 0.05). Benefit per drop (BPD) and net benefit per drop (NBPD) with tape were higher than drip line. Net present value, internal rate of capital return and benefit to cost ratio in drip line were higher than tape. In general, regarding technical evaluation tape was better than drip line, besides according to the economical evaluation the drip lines were better than tape.
