Abstract
Salinity continues to be a key factor limiting food security and agricultural sustainability in arid and semi-arid countries. Biochar has been promoted to reduce the risk of saline irrigation. In a controlled study, physiological and morphological growth factors of kochia plants that were irrigated with tap water (S1) and saline water (S2) were assessed to identify the ameliorative effects of biochar amendment to the soil at different levels (B1: 0%, B2: 2%, B3: 5%, and B4: 10%. According to our findings, salinity stress negatively affected morphological and physiological growth parameters of kochia plants by decreasing the fresh and dry weight (25% and 28%, respectively), plant height (30%), circumference (46%), total chlorophyll (51%), and relative water content (29%) when compared to the controls. Furthermore, electrolyte leakage increased considerably (19%) due to salt stress. Significant morphological and physiological growth enhancements were seen at all biochar levels in comparison to the control treatment, with the highest level increasing plant height by 55%, circumference by 76%, total chlorophyll concentrations by 121%, and relative water content by 28%. Furthermore, it resulted in a 36% reduction in the stressed plants' electrolyte leakage. The findings demonstrated biochar's benefits in reducing salinity's negative effects on kochia plants.

Abstract
The ever-increasing human population associated with high rate of waste generation may pose serious threats to soil ecosystem. Nevertheless, conversion of agricultural and food wastes to biochar has been shown as a beneficial approach in sustainable soil management. However, our understanding on how integration of biochar obtained from different wastes and mineral fertilizers impact soil microbiological indicators is limited. Therefore, in the present study the effects of agricultural (AB) and food waste derived (FWB) biochars with and without mineral fertilizer (MF) on crop growth and soil health indicators were compared in a pot experiment. In particular, the impacts of applied amendments on soil microbiological health indicators those related to microbial extracellular (C, N and P acquiring) enzymes, soil basal as well as different substrate induced respirations along with crop's agronomic performance were explored. The results showed that compared to the control, the amendment with AB combined with MF enhanced the crop growth as revealed by higher above and below ground biomass accumulation. Moreover, both the biochars (FWB and AB) modified soil chemical properties (pH and electric conductivity) in the presence or absence of MF as compared to control. However, with the sole application of MF was most influential strategy to improve soil basal and arginin-induced respiration as well as most of the soil extracellular enzymes, those related to C, N and P cycling. Use of FWB resulted in enhanced urease activity. This suggested the role of MF and FWB in nutrient cycling and plant nutrition. Thus, integration of biochar and mineral fertilizers is recommended as an efficient and climate smart package for sustainable soil management and crop production.
