Mineral nutrient analysis of three halophytic grasses under sodic and saline stress conditions

چکیده

Present study was carried out to assess the effects of soil salinity/sodicity on mineral nutrient status Urochondra setulosa, Leptochloa fusca and Sporobolus marginatus at ICAR- Central Soil Salinity Research Institute, Karnal, Haryana during 2016–19. Treatments (pH ~ 9.5, pH 10, ECe 30 dS/m, 40 dS/m 50 dS/m) were created in microplots (2.5 m × 1.5 0.5 m) using saline/sodic water. Na+ Cl– content (% DW) significantly increased with increasing sodicity/salinity stress condition all three grass halophytes, whereas K+ decreased. These halophytic species showed relatively less reduction Ca, Mg Fe contents up sodic 9.5 salinity level dS/m. Zn, Cu Mn decreased conditions but higher decrease observed under stress. The Na+/K+ Na+/Ca2+ ratio considered as indicators for measuring salt tolerance plants. grasses Leptachloa maintained their near 1.0 also below Higher pH~10.0 caused significant increase Sporobolus, highest level, value Na+/Ca2+. Changes accumulation patterns response is an important aspect positive correlation between Ca - & Zn negative Na K.

Applying Biochar and Mineral Amendments to Remediate the Chemical Properties of a Saline-Sodic Soil

The present study was intended to improve the chemical properties of a saline-sodic soil using the individual application of alfalfa residue and two biochars produced from sugarcane bagasse and walnut shell, at the weighting ratio of 5%; their concomitant application with gypsum, aluminum sulfate and the mixture of these two chemical amendments was considered. The experiment was conducted in th...

Saline/Sodic sub-soil on triticale, durum wheat and bread wheat yield under irrigated conditions

Sub-soil (> 30 cm) salinity and sodicity is a growing problem particularly in irrigated agricultural areas with rising water tables, poor water quality and/or deficient soil drainage. There were two objectives in this study; (1) to quantify the effect of sub-soil salinity and sodicity in grain yield of triticale, bread wheat and durum wheat and, (2) to determine if genotypes within and between ...
