Abstract
A filed experiment was carried out on salt affected soil at Kasr ElBasel village, south Etsa district, El-Fayoum Governorate, Egypt, during
the winter season 2013/2014. Objective of this work was to study the
effects of applied local compost at a rate of 20 m3 fed-1, amino acid
(proline) sprayed at rate of 3 mg/L fed-1 at 20, 45, and 60 days after
sowing) and biofertilizer (salinity durable bacteria) as either solely or
combined treatments on barley (Hordeum vulgare, c.v. Giza 123) growth
and yield parameters. The experimental field was irrigated with saline
water (a mixture of the fresh Nile water and agricultural drainage water).
The quality of the used irrigation water was classified as C2S1 (ECiw =
1.66 dS/m and SAR 5.35). The influence of treatments on some soil
properties (soil pH, ECe, ESP and available macro and micronutrient
contents) was studied.
Obtained results indicated that, the values of EC, ESP and pH,
decreased however, the organic matter and CEC increased with the
application of compost, proline and biofertilizer. The best treatment was
found to be (Compost + Proline + Biofertilizer) .The application of
(Compost + Proline + Biofertilizer) also, decreased soil bulk density,
while increased hydraulic conductivity , total porosity and soil moisture
content . Plant height, number of grains/ spike, number spikes / m2, 1000
grains weight, and grain and straw yields were also improved with
treatments. The greatest values were associated with the triple combined
treatment (Compost + Proline + Biofertilizer) as compared to the other
combined or solely ones.
It could be recommended that compost, proline and the
biofertilizer (salinity durable bacteria) could be used to alleviate the
hazardous effects of either soil or water salinity, which negatively
affected barley seed yield and quality.
