IMPACT OF NFERTILIZER RATE ON BARELY (HORDUM VULGARE) IRRIGATED WITH MAGNETIZED AND NON-MAGNETIZED SALINE WATER WITH APPLICATIONOF 15N STABLE ISOTOPE

Abstract

The experiment was conducted at Soil and Water Research Department Greenhouse, was carried out to study the effect of different levels of salinity stress on the barely crop also Study the effect of the water magnetization to reduce salinity effect and 15N in plant parts. Lowest grain yield of 11.68 g pot-1 by M0S2N0. This decrease in grain yield was by the low N fertilization and the salinity stress. Grain yield was 38.80 g pot-1 (M0S2N4) with an increase averaging 232.2%. The lowest straw dry matter yield was 10.60 g pot-1 given by M0S3N0. Plants werfaced difficulty to absorb N because of salinity. The highest straw yield was 26.40 g pot-1 (M1S0N4) with 149.1%. The highest straw N uptake was 197.9 by M1N4S0 with 343.7%. The lowest N uptake in grains was 117.9 g pot-1 by M0S1N3. The highest grains N uptake was 372.9 g pot-1 by M0 S2N2 216.3% increse N recovery by straw ranged was 0.11 to 7.76 g pot-1 due to M0S0N3 and M1S2N1, respectively. The main effect of magnetization was an increase due to M1. The main effect of salinity show an increase in NR when the salinity was in medium rates. N recovery by grains ranged from 0.65 to 25.14 g pot-1 due to M0S0N1 and M1S1N1, respectively.
