Abstract
The concept that salinity hazards to sensitive crops can be reduced by adequate fertilization, was studied. Peanuts (Arachis hypogeae L. ) were grown for two years on sandy dunes with 1. 0-6. 5 dS m** minus **1 irrigation water and differnt concentrations of potassium (K) and nitrate (NO//3), which were applied by the trickle-irrigation system. The results showed that dry matter production in 4. 5 dS m** minus **1 was about the same as in 1. 0 dS m** minus **1 when 11. 6 mM KNO//3 applied. Similar results were obtained with pod yield in 1983, but not in 1984, when increase in the water salinity from 1. 0 to 4. 3 dS m** minus **1 abruptly reduced pod yield. The conclusions are that the tested concept is basicly valid. The major effect of salinity on the crop was due to Na-K interaction in uptake by the plant. Further work is needed to define the conditions which may affect the gonophores penetration into the saline soil.
