The study’s purpose was to reduce the oxidative stress, seasonal physiological changes of paspalum vaginatum and ameliorate soil properties through the addition of banana waste biochar and compost. Different rates of organic amendments were incorporated into sandy loam soil to investigate their impact on paspalum physiological, biochemical, and development in pot and field settings over three seasons (winter, spring and summer). Under the conditions of these two places, paspalum leaves gas exchange characteristics, stomatal traits, anatomy traits, relative water content, proline, antioxidant enzyme activities, and paspalum pigments were determined. For the irrigation system, two rates were chosen: 20% and 60% of the water holding capacity of the control plot WHC. In this study, two advanced statistical analyses were conducted. A factor analysis of mixed data (FAMD) was performed for the analysis of the effect of our charcoal on soil data. Meanwhile, the impact of banana waste biochar on biological activities was investigated using multiple factorial analysis (MFA). The use of biochar and compost blends boosted the cation exchange capacity (CEC) of treated soils, according to our findings. Furthermore, the use of banana waste biochar improved biological basis in the summer season compared with previous seasons. Different antioxidant capacities in seashore paspalum were boosted in the improved soils compared to the untreated ones.

The current study aimed to evaluate the effect of banana waste biochar on the physiological traits and growth of Paspalum vaginatum under three water treatments (100%, 80%, and 60% of the water holding capacity (WHC) of the soil). A plastic pot experiment was done for the germination of paspalum vaginatum. The treatments were the addition of compost, banana waste biochar, or banana waste biochar and compost combination to the soil. We used multiple factor analysis (MFA) to reveal the relationship between the effect of banana waste biochar and the three water regimes on physiological data. The findings revealed that banana waste biochar had an important impacts on all traits under various water supply conditions. The photon yield of PSII of control treatment at three water regimes had the lowest response compared to amended treatments. Changes were observed in chlorophyll pigment among different treatments.
