Effect of potasium on salt tolerance plants irrigated with saline waters
1983
Eleizalde Luzárraga, María Benigna | Larsen, S.
Under greenhouse conditions, the effect of potassium on the salt tolerance of tomato and pepper plants, irrigated with saline waters was studied. these plants grown on sansy and calcareous soils, which have received 0.200 and 400 ppm of K previosly and an appropiate addition of 400 ppm P as monocalcium phosphate. Duiring this trial, these crops were irrigated weekly at 60 % field holding capacity with two different types of saline waters and a suitable supply of a complete nutrient solution minus K and P. Under all saline conditions developed by the irrigation, the potassium applied to soils help at the growth and composition of crops. In the last two weeks, a dieback was produced on tomato plants by the sea irrigation due to the Cl upyake by this crop.
