“…Our present research findings were coincidence with other previous researcher (Helliwell 2015;Tian et al 2017). Helliwell (2015) suggested that the addition of biochar had no apparent effect on plant growth. Tian et al (2017) described that there was no significant effects of biochar addition on plant total fresh mass, leaf mass, root fresh mass, root dry mass up to 16% biochar treatment.…”

“…Trupiano et al (2017) showed after 5 weeks of plantation, there was no significant effect of biochar addition on plant leaf width, perimeter, length and area as well as all the agronomic parameters were altered at identical rate. Biochar can increase above-ground and below-ground biomass in some circumstances, for example higher percentage of biochar addition or different sources of biochar addition (Helliwell 2015). But in our experiment, source of biochar production was not significant, because we used only banana peel as source of biochar production (N: 9.5 g kg −1 , K: 42.55%), but some researcher used rice husk; N: 6.5 g kg −1 , K: 14% (Carter et al 2013), pinewood, N: 5.44 g kg −1 , P: 0.65 g kg −1 , K: 1.64% (Tian et al 2017), orchard pruning biomass, N: 9.1 g kg −1 , P: 12.2 g kg −1 (Trupiano et al 2017), etc.…”

“…(Carter et al 2013;Tian et al 2017;Trupiano et al 2017). Previous studies were designed as 4% biochar application rate was the threshold limit (Carter et al 2013;Helliwell 2015;Tian et al 2017) but increased above-ground biomass of plants (Carter et al 2013;Tian et al 2017) and also had some reports of excess biochar application rate decreased yield relative to control (Asai et al 2009;Hammond et al 2013). Currently, little research works were dedicated regarding lower biochar application rate (< 4%) and its effects on agronomic plant growth parameters (Biederman and Harpole 2013;Qian et al 2018).…”

Purpose Biochar addition to soil is immensely beneficial for increasing plant productivity and C sequestration, attenuating nutrient leaching loss, counteracting heavy metal contamination and organic waste triggered environmental pollution. To understand the sustainable benefits of biochar, two pot experiments were conducted under net house condition in Khulna University, Bangladesh. Methods Biochar was prepared from banana peel waste through slow pyrolysis process under limited oxygen condition. Three lower rates (1, 2 and 3%) of banana peel biochar (BPB) were added with agricultural soil along with control with three replications for each. After incorporation of BPB into soil, pots were kept under field condition for 7 days and then the seeds of Ipomoea aquatica were sown. Plants were harvested after 42 days from seeds sowing and plant height, leaf number, fresh weight, and dry weight were measured. Another pot experiment was also conducted under sand medium to test the BPB as K-rich soil amendment where K was applied from two different sources (KCl and BPB) along with control. Seeds of Cucurbita moschata were sown and 40 days after seed sowing, K deficiency was observed in control treatments. Results Banana peel biochar was found to be rich in K content. Plant productivity and above-ground biomass were reduced in 1% BPB treatments, but increased in 2 and 3% BPB treatments as compared to control but statistically insignificant (p < 0.05). In case of second experiment, K deficiency symptoms were observed in 40 days aged Cucurbita moschata seedlings under control treatments, whereas no K deficiency symptom was noticed in plants grown under K supplied from both KCl and BPB. Moreover, the plant grown with BPB was found healthy, stronger and greener in appearance. Conclusion This positive influence of BPB on plant growth suggests the alternative way to overcome the use of chemical fertilizer and effective way of utilization of agricultural wastes through recycling.

“…Biochar is a substance with a high carbon content, which has been widely studied in recent decades as a soil enhancer material to promote soil quality, reduce greenhouse gas emissions, and to achieve improved crop yields (An and Huang, 2015;Gascó et al, 2016;Helliwell, 2015). The addition of charcoal, ash, or biochar to soils can change soil chemical (Horel et al, 2019a;Jien and Wang, 2013;Liang et al, 2006), microbial (Anderson et al, 2011;Horel et al, 2018), and physical-hydrophysical properties (Jien and Wang, 2013;Liang et al, 2006;Novak et al, 2009;Sun and Lu, 2014).…”

A b s t r a c t. A great emphasis has been placed on biochar addition to soils to improve its physical, chemical, and biological properties in recent times in order to achieve improved crop growth and yields. The present study explored to soil physical changes through different plant growth stages caused by biochar addition to silt loam soil in a pot-experiment. Our research focused on changes in soil bulk density, aggregate size distribution, and saturated hydraulic conductivity. The soils were amended with different amounts of biochars (control with 0, BC0.5 with 0.5%, BC2.5 with 2.5%, and BC5.0 with 5.0% biochar, by weight). Capsicum annuum L. were planted at a two-four leaf stage. Soil samples were taken at 6, 10 and 12 weeks after planting. The biochar amendment resulted in a significant decrease in soil bulk density values. Soil saturated hydraulic conductivity values ranged between 5.5 and 7.9 times higher for all treatments compared to the controls.
