Effect of saline irrigation water on yield and yield attributing characters of tomato (Solanum lycopersicum L.) varieties

Salinity is one of the most important factor limiting fruit growth and production of several horticultural crops. A pot experiment was undertaken during Rabi 2017-18 at Department of Agricultural Chemistry & Soil Science, JAU, Junagadh in order to investigate the effect of different levels of saline irrigation water on yield and yield attributing characters of tomato (Solanum lycopersicum L.) varieties. The experiment consists of four salinity levels viz., < 2.0, 4.0, 6.0 and 8.0 dS m-1 with four different varieties viz.,V1: GT-6, V2: JT-3, V3: AT-3 and V4: DVRT-2 of tomato. Results reported that saline water treatments significantly reduced the vegetative growth parameters and hence total yield of tomato. The yield and yield attributing characters were also significantly influenced by different tested varieties of tomato and recorded highest yield with V1 (GT-6) variety.
