Abstract

Salt stress became the most challenge for agriculture production and development. Two practical trials were carried out in a private farm at Abdo Basha Village, Kafr El-Dawwar, Behaira Governorate during two winter growing seasons 2017 and 2018 seasons to study the effect of the irrigation levels with salt water i.e., (9000, 18000, 24000 and 36000 ppm of water salinity and Nile water as control) on growth, yield and accumulation of salt in different plant parts of Salicornia grown in boxes in cultivated soil.
Results indicated that plant height, leaves number, number of branches, fresh and dry weights of shoots increased with increasing salt water levels at 80,120,150 and 180 days of plant age during 2017 and 2018 seasons. Also, root growth characteristics i.e., root length, fresh ad dry weights were increased with increasing salt water levels at 80,120,150 and 180 days of plant age during 2017 and 2018 seasons. Yield and seed yield were increased with salt water levels during 2017 and 2018 seasons. Different salt irrigation water levels i.e., 9000 ppm salt water, 18000 ppm salt water, 24000 ppm salt water and 36000 ppm salt water) decreased salt concentration (ppm) in soil at 0, 80, 120, 150 and 180 days of plant age during 2017 and 2018 seasons. The control gave the lowest value for soil salt concentration (ppm) at different plant stages during the two growing seasons. Increasing salt water levels decreased salt concentration in soil attributed to the salt water percentage during plant life time in both seasons. The most beneficial treatment for increasing yield and its components and decreasing the salt from the soil was that36000 ppm of salt water during first and second seasons.
