Synthesis and application of biochar in conjunction with various amendments to improve salt-affected soil and crop productivity

Abstract

Soil salinity is an important abiotic constraint that affects soil quality and crop productivity and has a direct impact on crop yields. Ensuring the sustainable use of saline soils while maintaining environmental integrity is of utmost importance. To achieve this, it is essential to explore and implement methods that can enhance productivity without causing harm to the ecosystem. In the current study, the effect of biochar, Simultaneous inoculation of biomes (Trichoderma harzanium and Pseudomonas fluorescence) and gypsum on soil properties and growth parameters of chickpea was investigated. Of all treatments, the combination of 75 percent GR + biochar@20t/ha and biome @2kg/ha had the greatest effect on lowering pH (9.32 to 7.61), EC (3.65 to 1.6 dSm-1) and SAR (24.22 to 5.9 Cmolc (+) kg-1). As a result, there was a notable improvement in the length of chickpea shoots and roots as well as the overall production of dry matter.
