Response of two wheat cultivars to compost application in saline soils [electronic resource]

Includes references.

Tow field experiments were conducted on a saline clay soil in Village ElRowad
in Sahl El-Hussinia, El-Sharkia, and Governorate. The location lies between
latitude 32° / 00 to 32° / 15, N and longitude 30° / 50 to 31° / 15 E. For two successive
winter seasons 201712018 and 201812019 cultivated with two wheat (Triticium aestivum
cv.) cultivars, to study the effect of soli salinity levels and compost on some soil
chemical properties growth and grain yields of both cultivars wheat (Masr1 and Sakha
93). In two seasons, each experiment was carried out in split plot design with four
replicates.
Results obtained that, the decreases of soil salinity for soil treated with compost after
wheat Sakha 93 harvest. The decrease of soil salinity in the soil cultivated by Sakh 93
was higher than that found in the soil cultivated by wheat Masr1 respectively. On the
other hand, the soil pH values were decreased from 8.7 to 7.98 in first season and 8.02 to
7.90 in second season as a result of compost applications. Also, the soil contents of
available the N, P, K, Fe, Mn and Zn available in soils were increases with decreasing soil
salinity in both seasons as a result of compost application. Plant length (cm); spike
length (cm); No. of tiller/plant; No. of leaves/plant and No. of spike !plant were decreases
with increasing soil salinity level, where these decreases with the plants of Sakha ~3
cultivar were higher than theses found with the plants of Masr 1 cultivar. The application
of compost to the soil had a decreased effect on wheat yield •and yield components i.e.
weight of spike/plant (g), weight of grains/spikes (g), weight of 1000 grins (g), straw yield
and grains yield (ton/fed). In addition compost applications resulted in an increase of
wheat plants uptake of N, P, K, Fe, Mn and Zn where, the content of these nutrients in
grains sakha 93 than Masr1 varieties wheat. The effect of saline soil different levels on
wheat varieties quality i.e. Carbohydrate (%),protein and chlorophyll (mg g-1 f.w.) were
increased decrease of soil salinity especially sakha 93 with or without compost than
Masr1 in both sessions while the praline (mg g-1.f.w), content in grains of wheat plants
was increases with increasing soil salinity level without compost .
Recommendation:
The obtained data concluded that, the application of compost led to improve soil salinity
properties and increase of wheat cultivar Sakha 93 productivity and its quality compared
by Masr1 cultivar under saline soil conditions
