ABSTRACT: Recently, biochar has emerged as an effective nutritive source that plays a noteworthy contribution in improving the growth of various crops. Current research signifies the role of Biochar-composite in the growth of wheat seedlings. In this study, the carbonaceous biomass synthesized from garden waste was impregnated with macro- and micro-nutrients. The effectiveness of this synthesized Biochar-composite (GW-B) was studied by using wheat (Triticum aestivum) as an experimental crop. The GW-C was applied to wheat seeds grown in petri plates and pots by supplementing them with different concentration of prepared biochar. Application of biochar composites improved the growth of wheat seedlings in both petri plates and pots in addition to enhancement in morphological attributes. Higher concentration of biocharcomposites improved the morphology of wheat seedlings in a dose-dependent manner e.g. shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, number of leaves per plant, plant height, leaf area and root length. Biochar-composite at concentration of 0.8 enhanced morphology of supplemented wheat seedlings sown in petri plates at equidistance manner over 5 layers of Whatman filter paper (no. 1). Biochar-composite of 0.03 g enhanced the morphological attribute of wheat seedling that were sown in equidistance manner in pot experiment. It was found that biochar amended soil improved the growth and morpho-physiological attributes of wheat seedlings, thereby enhancing the yield of crop.
