| Abstract:
Effects of saline irrigation water and soil texture on potato growth and yield have been studied separately. The experiment was carried on two soils (clay and loam) and irrigated with different water qualities. Values of electrical conductivity (EC) for saline waters were 2.3, 2.7 and 3.6 dSm-1; for local fresh water EC was 0.9 dSm-1. Plant growth (leaf area and dry matter), showed that salt stress reduced the leaf surface and consequently the biomass. Yield and evapotranspiration were sensitive to salinity and soil texture, but water use efficiency was not affected. Tuber yield on clay soil was almost 30% lower than loam. | |
