EFFECT OF WATER QUALITY AND THE ADDED NUTRIENT SOLUTION'S CONCENTRATION ON BARLEY SPROUT HORDEUM VULGARE L PRODUCTION

Abstract

A laboratory experiment was carried out in the Hydroponics Laboratory of the Department of Field Crops, College of Agriculture, University of Basrah for the 2018-2019 year to know effect of water quality and the concentration of the nutrient solution added on the production of cultured barley. The study included two factors; the first factor uses two types of water (R.O) and its symbol W1, (Tap water) its symbol W2, and the second factor is a plant nutrient NPK with a concentration of 30% N, 12% P, 8% K, where four concentrations of the nutrient were used in the following quantities: 0, 5, 10, 15 g l, which symbolized by the symbols (T1, T2, T3, T4) on the relay. The experiment used a completely randomized design (CRD) with three replications. The following characteristics (plant height, total wet weight, total dry weight, total green forage yield) were studied. The experiment results showed that the (R.O) water treatment was superior in all the studied characteristics, and the concentration of 10 g l of nutrient solution gave the highest average in a characteristic of plant height reaching 21.68 cm and total dry weight (0.38) g. Dish-1, as for the interaction between the quality of added water and the concentrations of nutrient solution, did not show any significant effect in all characteristics.
