PHYTOREMEDIATION OF SALT AFFECTED SOIL FOR THE PRODUCTION OF FODDER PLANT

Abstract

The practical part of this study was carried out in a private farm at Abdo Basha Village, Kafr El-Dawwar, Behaira Governorate during two winter growing seasons of 2017 and 2018 seasons to study the effect of the irrigation levels with salt water i.e., (Tap water as control, 25 % salt water, 50 % salt water, 75% salt water and 100 % salt water) on growth, yield and accumulation of some salts in different plant parts of Salicornia plants grown in boxes in cultivated soil. II- Effect of salt water levels on Salicornia seed germination. Optimal germination for seeds of Salicornia occurred in distilled water treatments at 25 ° C The treatments at 18 ° C had the lowest germination percentages at all salinity regimes tested. Salinity increments inhibited germination of seeds in all temperature treatments. The smallest decrease in germination from T3 treatment at 25°C No seeds could germinate in T4 solutions at any of the temperatures used. II-Effect of irrigation by salt water levels on growth characteristics of Salicornia plants during different plant stages: - II-I- At 80 days of plant age: Different level of irrigation salt water i.e., (0,25 %,50 % and 100 %) increased plant length cm, root length cm, Num. of leaves /plant, Num. of branches /plant, Root fresh weight g/plant, shoots fresh weight g/plant and shoots dry weight g/plant when compared with control (irrigated with normal water) at 80 days of plant age during 2017 and 2018 seasons. The highest value of plant length,root length cm/plant, Num. of branches/plants and root fresh weight /plant at 60 days of plant age during 2017 and 2018 seasons, were50 % of salt water followed by 75 % salt water when compared with control treatments.
