Abstract

Increase salinity in soil and water resourses in agricultural lands has created major challenges in crops production. Kochia can grow under saline conditions and used as fodder in dry and saline areas. Therefore, three experiments was conducted in complete randomize design with four replication, to study effects of different levels of salinity (0, 10, 20, 30, 40, 50 and 60 dS m-1) at different growth stages (planting and early seedling) and salinity appllication intervally. Results of applying saline water at the beginning of growth showed that kochia seedling was able to survive up to 30 dS m-1 sodium chloride. The results showed that increasing salinity at planting and early seedling satge reduced plant height, branches number, shoot fresh and dry weight, and increased digestible dry matter, digestive value, and crude protein yield. On the other hand with increasing salinity digestibility of dry matter, organic matter digestibility, crude protein and ash percentage were increased. Total phenol was not significantly affected by salinity in all treatments. Application of salinity intermittently at early seedling except of digestive value and ash percentage had no significant affect on other treats. Generally, results showed that the kochia seedlings are sensitive to salinity higher than 30 dS m-1 and also kochia be able to keep biomass production with salinity appllication intervally.
