  • Effect of biodegradable plastics on greenhouse gas emission and paddy rice growth under flooding conditions Reviewed International journal

    Biodegradable plastics applied to soil stimulate the production of greenhouse gases and inhibit plant growth under aerobic conditions. This study aimed to examine the effects of biodegradable plastics on paddy rice growth and greenhouse gas emission under flooding conditions in pot experiments and also on greenhouse gas production under flooding conditions in an incubation experiment. Two series of pot experiments were conducted with rice (Oryza sativa). First series as immediate flooded and 2nd series as 2 weeks nonflooding before flooded, and both kept flooded until harvest. The following four kinds of materials were added to the sandy paddy soil, 1) nonwoven fabric sheets made of polylactic acid and polybutylene-succinate, 2) laminate sheets made of polybutylene adipate terephthalate and pulp, 3) cellulose filter paper, and 4) rice straw. Only soil was used as control. Methane (CH4) emission, measured by chamber method followed by gas chromatography, was significantly larger only in the cellulose treatment than the laminate treatment in the immediate flooded series, indicating that biodegradable plastics had no significant impact on CH4 emission from paddy rice soil. Rice growth and yield did not show significant difference among treatments in both series. Incubation experiment showed the largest CH4 production in cellulose-amended soil, followed by straw-amended and laminate amended soils, and least in fabric-amended soil, while CO2 did not show significant differences among treatments. We need further examination with different biodegradable plastics for a longer period that test used in this study.

    This study aimed to investigate the effect of fresh and residual biochar on the physiological attributes and quality of wheat grain. The research trial was conducted in the field applied with fresh biochar (S1), one-season-old residual biochar (S2), and two-season-old residual biochar (S3). The treatments include T1 (absolute control), T2 (100% RDF), T3 (100% NP), T4 (NP + rice husk biochar 5 t/ha), T5 (NP + rice husk biochar 10 t/ha), T6 (NP + rice husk biochar 15 t/ha), T7 (NP + rice straw biochar 5 t/ha), T8 (NP + rice straw biochar 10 t/ha), and T9 (NP + rice straw biochar 15 t/ha). A significant impact of fresh biochar application (S1) over one-season-old biochar (S2) and two-season-old biochar (S3) was recorded. In S1, the application of biochar at a rate of 5 t/ha (T4 and T7) showed enhanced chlorophyll index (+17.3%), relative water content (RWC) (+9.6%), membrane injury index (MII) (+8.1%) along with the carbohydrate (+12.7%), and protein content (+49.9%) in wheat grains. In one-season-old biochar (S2), as compared to the control, a notable improvement in the chlorophyll index (+13.8%), MII (+7.2%), membrane stability index (+27.1%), carbohydrate (+5.9%), and protein content (+32.3%) of wheat grains in treatment no. T5 & T8 (i.e. 10 t/ha). While in two-season-old biochar (S3), the treatment no. T6 & T9 (i.e., 15 tons/ha) had a significant impact on chlorophyll index (+7.2%), RWC (+4%), MII (+3.6%), membrane stability index (+12.5%), as well as the carbohydrate (+2.7%) and protein content (+10.2%) of wheat grains.
