Application of banana spathe extracts and compost for improving growth in rice plants

Abstract

The application of agro-waste in the form of compost is an ecofriendly approach to minimize the use of chemicals for crop improvement. Hence, compost was prepared by the Indore method from banana spathe obtained from five popular varieties of banana cultivated in Tamil Nadu, India, and its growth promoting ability was tested on the rice cultivar CO-51. The banana spathe was applied as both an aqueous extract and compost to evaluate the growth parameters in bioassays and pot culture experiments. The compost improved the growth in terms of root length, shoot length, biomass, tillers, length, and width of flag leaf and yield in CO-51 rice cultivar significantly (p < 0.001%) when compared to the untreated control and fertilizer-treated plants. The maximum yield was observed in the treatment with Rasthali spathe. Biochemical analysis of the compost-treated rice plants showed an increase in chlorophyll, carotenoid, carbohydrate, protein, and amino acid content when compared to the untreated control plants. The results from the study suggest that the banana spathe compost could be used as an effective organic fertilizer for the growth of rice plants thus providing a strategy to reduce landfills, as well as the use of fertilizers, thereby further helping to protect the agroecosystem.

Antibacterial Activity of Green Synthesized Silver Nanoparticle using Banana Flower Extract

“…UV-visible spectral scanning was used to periodically monitor the synthesis of silver nanoparticles. On Systronics UV-Visible spectrophotometer 117, a UV-Visible spectrograph of the colloidal solution of silver nanoparticles was recorded as a function of time [15].…”

Riesgo patogénico por Aspergillus fumigatus en la producción de compost de Musa paradisiaca

“…El compostaje de estos desechos agrícolas se considera más respetuoso con el medio ambiente que los residuos municipales debido a que contiene menos cantidad de metales pesados contenido (Carabasa et al, 2020). Aunque una serie de materias primas de los residuos agrícolas están disponibles, siempre hay una búsqueda constante de nuevas fuentes para encontrar un mejor sustrato que tenga un mayor valor nutritivo para reemplazar el fertilizantesquímicos (Suganthi & Kavitha, 2022). Por lo tanto, el compostaje es una importante alternativa de degradación biológica de la materia orgánica hasta su estabilización (Haug, 1993), que se lleva a cabo por diversas y sucesivas poblaciones de microorganismos (Canales & Padilla, 2010).…”
