To evaluate the effects of different levels of nitrogen (N) and salinity on yield and growth indices of tomato, a factorial experiment with a completely randomized design and three replications was performed in greenhouse conditions. Treatments included four levels of salinity (0.5, 2.5, 4.5 and 6.5 dS/m as NaCl) and four levels of N (0, 60, 120 and 240 kg/ha). The results showed that fruit yie...

    Nowadays salt tolerance of crops is becoming more and more important, owing to the constant increase of salinity in arid and semi arid regions. This research was carried out in order to test of different salinity levels effects on yield of barley (Hordeum Volgar L.) genotypes, in split plot experiment on the base of Randomized Completely Block Design with 3 replications. Salinity treatment ...
