A pot culture experiment with nine treatments and three separate replications was established in a completely randomized design (CRD). It evaluated at Bidhan Chandra Krishi Viswavidyalaya (Agricultural University) Mohanpur, WB, India, for 2 years row from January to June 2021 2022. The comprising bioformulation treatments, namely, T1: recommended dose of fertilizer (RDF, 20 t FYM + 75:75:50 kg NPK ha–1), T2: farmyard manure (FYM) @ ha–1, T3: T2 3% panchagavya, T4: 6% T5: 9% T6: 5% jeevamrutha, T7: 7.5% T8: 10% T9: control (no nutrients bioformulations), the growth, quality, yield kalmegh along study soil characteristics two consecutive years. Pooled results revealed that T5 had highest values plant height (74.45 cm), spread (36.36 cm2), primary (26.26) secondary (29.18) branch number per plant, leaves (94.01) leaf area (559.50 cm2) fresh (42.94 g) dry (18.85 herbage total chlorophyll (4.392 mg g–1), andrographolides (2.925%).

The Evolution of Nutrient and Microbial Composition and Maturity During the Composting of Different Plant-Derived Wastes

Biology, Journal Year: 2025, Volume and Issue: 14(3), P. 268 - 268

Published: March 6, 2025

Composting is an environmentally friendly treatment technology that recycles and sanitizes organic solid waste. This study aimed to assess the evolution of nutrients, maturity, microbial communities during composting different plant-derived wastes. The process was conducted over 49 days using three types waste: wheat bran (WB), peanut straw (PS), poplar leaf litter (PL). examined through physical, chemical, biological parameters. results revealed after composting, groups experienced significant changes. They were odorless, insect-free, exhibited a dark brown color, had alkaline pH value, electrical conductivity (EC) value less than 4 mS/cm. These characteristics indicated they reached maturity. Nutrient content most factor influencing degree humification materials, while changes in community diversity key driving factors. Significantly, compost PS, derived from straw, entered thermophilic phase first, by end it lowest matter (OM) loss rate (17.4%), with increases total nitrogen (TN), phosphorus (TP), potassium (TK) order PS > PL WB. increase humus carbon (HSC) humic acid/fulvic acid (HA/FA) ratio followed WB PL. FTIR spectra greater aromatic compared other samples. abundance bacterial fungal increased significantly, accompanied more complex structures. Crucially, there no phytotoxic effects any treatments, boasted high germination index (GI) 94.79%, heavy metal contents. findings indicate has highest potential for resource utilization suitable agricultural applications.
