Abstract
A field experiment was conducted at Udaipur (Rajasthan) during rabi season of 2021-22 to evaluate the effect of water stress and biochar application on biochemical and physiological processes in wheat. The experiment consisted of four levels of water stress as main-plot and four levels of biochar as sub-plot treatments conducted in split plot design (SPD) replicated thrice. Results revealed that water stress at various growth stages and biochar application had effect on proline, chlorophyll and relative water content (RWC). Water stress at grain filling stages resulted in higher chlorophyll and relative water content as compared to no water stress. Further, water stress at tillering stages resulted in higher proline over no water stress. Application of biochar had no effect on proline and chlorophyll contents Further, application of Biochar @ 4 t/ha in significant relative water content.
