Abstract | ||||
A lysimeter experiment was carried out at Agricultural Research Station, Sakha, Kafr El-Sheikh governorate, during the growth season of 2013/2014 to study the effectiveness of potassium humate on improving the tolerance of wheat plants to saline conditions and its effect on some metabolic products. Irrigation of wheat plants with diluted sea water i.e. EC 6, 9 and 12 dS/m decreased chlorophyll a, chlorophyll b & carotenoids contents and total protein contents but increased total carbohydrate and proline contents. Soil addition of potassium humate at (4 & 8 kg/feddan) increased the metabolic products of wheat plants under unsalinized conditions; the low rate of potassium humate gave better increments than the higher one. Additionally, this material ameliorated the depressive effect of salinity on wheat plants. | ||||
