Nursery inoculation of tomato with arbuscular mycorrhizal fungi and subsequent performance under irrigation with saline water

摘要: Protected horticultural crops as well those planted in open fields particularly the Mediterranean region have to cope with increasing salinization ofirrigation water. High salinity of supply water has detrimental effects on soil fertility and plant nutrition reduces crop growth yield. This study was conducted determine if pre-inoculation transplants arbuscular mycorrhizal (AM) fungi alleviates salt yield tomato (Lycopersicon esculentum Mill. Cv. Marriha) when irrigated saline Tomato seeds were sown polystyrene trays 20 cm 3 cells treated AM or without (nonAM) Glomus mosseae. Once seedlings reached appropriate size, they transplanted into nonsterile concrete blocks (1.6 m 3m 0.75 m) under greenhouse conditions. The electrical conductivity (ECe) 1.4 dS 1 .
