The effects of pyrolyzed agricultural waste generated from banana leaves on the development and physiological responses of Paspalum vaginatum in different water conditions were investigated. X-ray diffraction (XRD) and Fourier-transform infrared (FTIR) computations were utilized to describe the banana-waste biochar and determine the crystalline structure and functional groups. A plastic pot was used in two trials to examine the effectiveness of the studied biochar under two situations (well-watered Ww and limited-watered Lw). Seashore paspalum was cultivated in loam soil that had been modified with biochar as a single addition and a biochar compost mix. Six water scarcity scenarios were chosen (100, 80, 60, 25, 20, and 15% of water holding capacity (WHC) of the control soil). To analyze the varied responses of P. vaginatum in well-watered and limited-water environments, principal component analysis (PCA) was used. Under Ww, photosynthesis, biomass, fluorescence, and chlorophyll content increased, whereas, under Lw and control, they declined. Biochar and compost combinations enhanced the relative water content (RWC) more than biochar alone or in combination. Conversely, stomatal density in drought-stricken plants showed the reverse trend.

Around the world, the increasing population and consumption are placing huge demands on food. Agriculture is considered one of the important sectors in the world and the force to feed humanity. While under these circumstances, which stand out by successive years of drought, degradation of soil,...

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...

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...

A plastic pot open-air trial was conducted with the Paspalum vaginatum (seashore paspalum) using different rates of biochar or compost addition to sandy loam soil and two water treatments (60% and 20% of the water-holding capacity of the control) during three seasons (winter, spring, and summer). Paspalum growth, physiological characteristics, and physicochemical properties of soil were investigated. The effect of biochar on soil properties was assessed using factor analysis of mixed data (FAMD). Additionally, multiple factorial designs (MFA) were used to examine the impact of three biochars on physiological functions. Peanut hull biochar application increased soil fertility and chlorophyll concentration of paspalum leaves significantly compared to the other biochars. Physiological characteristics were significantly improved with peanut hull biochar under summer compared to winter and spring due to the accumulation of nutrients in the soil by the decomposition of biochar. The application rate of the three biochars reduced the water requirements of paspalum. The best result was obtained by incorporating 6% peanut hull biochar into the soil, which resulted in better soil quality and healthy grass in dryland conditions while using 47.5% less water. These findings can be suitable for golf managers and can serve as a solution for dry zones.
