Nutrient-feeding strategy promotes the growth, biomass, and quality of genotype/variety CIM Megha of Kalmegh

The current study used two harvesting periods (2020-21 and 2021–2022) to investigate the effects of organic and inorganic fertilizers applied to the soil on Kalmegh growth, productivity, and economic viability. The study looked at a variety of growth parameters, including plant height, the number of primary and secondary branches, plant spread, leaf area, dry matter accumulation, and fresh, dry, and seeded herbage output. T6 (RDF + VAM + Vermicompost) produced much higher growth metrics and yields than other treatments, exhibiting consistently better performance. The improved outcomes were attributed to the combined effects of inorganic fertilizers, mycorrhizal association (VAM), and organic supplementation (vermicompost). T2 (RDF + vermicompost) displayed a similar performance. On the other hand, the T7 control group had the lowest values across all metrics. The economic study determined that T6 was the most economically viable choice due to its higher gross and net returns. This emphasizes the importance of coordinated nutrient management in achieving optimal agricultural output and economic sustainability. According to the study's findings, T6, which has a balanced mix of inorganic and organic amendments, is a promising technique for increasing kalmegh variety CIM Megha production. This technique provides higher crops, financial rewards, and improved soil nutrient levels.
