“…Since biofertilizers are known to enhance rhizospheric surface (Elanchezhian and Panwar 1997;Dalawai and Naik 2014;Choudhury et al 2020), the healthy microbial population in T5 was due to the availability of surface as well as substrates for microbial growth. This agrees with the findings in other cropping systems that organic amendments build a healthy soil organic carbon base required to grow and maintain soil microflora (Chhotaray et al 2014;Cao et al 2021;Gao et al 2022). Mockeviciene et al (2021) reported that longterm application of organic manure maintained favorable conditions for soil microbes and carbon sequestration.…”

“…There are reports that organic amendments significantly enhanced the density of bacteria and fungi in agricultural soil (Chhotaray et al 2014;Cao et al 2021;Wu et al 2021). In the present case, all organically amended plots, with or without fertilizer application, had significantly higher levels of bacteria and fungi than the unamended or fertilizer-amended ones.…”

Abstract. Mohanty A, Acharya S, Swain BB, Mishra S, Mohapatra D, Mohapatra PK. 2023. Integrated nutrient management enhances the growth efficiency and productivity of Tagetes erecta cv. Sirakole. Asian J Agric 7: 88-97. The African marigold (Tagetes erecta L. cv. Sirakole) is a highly significant plant because it can be cultivated year-round, produce large blooms, have a long post-harvest life, and compactness. To determine the optimal fertilizer and manure combination, we conducted a study to explore the plant's morphological, yield, and physiological characteristics under different combinations of fertilizers, Vermicompost (VC), Poultry Manure (PM), and biofertilizer (Azospirillium + phosphate solubilizing bacteria). The most successful combination for promoting vigorous growth, dense canopy, prolific branching, longer flowering duration, large-sized flowers, and higher yield was achieved with 50% Recommended Dose of Nitrogen and Phosphorus (RDNP) + VC equivalent to 25% Recommended Dose of Nitrogen (RDN) + PM equivalent to 25% RDN + biofertilizers (@400 gha-1). Additionally, plants in this combination exhibited higher chlorophyll content (Chl) and photosynthesis (PN) than those in plots with RDNP alone or other amendments. While photosynthetic fluorescence yield jP0) and energy dissipation (jD0) did not vary, plots with RDNP had lower excitation (?0) and electron movement (jE0), as well as lower photosynthesis performance indices (PIs), compared to the nutrient combinations. Additionally, the organically amended plots showed higher microbial density and soil enzyme activities than those with RDNP alone. Our findings indicate that using a combination of fertilizer, manure, and biofertilizers is the most effective way to improve the photosynthetic capacity and flower yield of T. erecta cv. Sirakole.

“…Pan et al conducted a 30-day incubation experiment to investigate the ameliorating effects on an acidic ultisol with four crop straw decayed products (SDPs), and the results showed that the soil pH increased by 55%-75% [36]. Nevertheless, the research results of Cao et al showed that straw coverage with no-till and rotary tillage significantly reduced the soil pH from 7.7 to 7.4 and 7.2 [37]. In another study, it was observed that the application of crop residues to soil increased the pH of topsoil (0-10 cm) and subsoils, and the effects can persist over 26 months [38].…”

“…Regarding soil pH, all the rice residue management practices showed a decrease compared to CT. Supporting this finding, Cao et al [58] reported a significant reduction in soil pH from 7.7 to 7.4 and 7.2 with straw coverage in no-till and rotary tillage, respectively. Similar results have been reported by various researchers [59][60][61].…”

Rice–wheat cropping system (RWCS) is a dominant agricultural practice in the Indo-Gangetic plains, particularly in the North–Western states of India. The prevalent practice of open burning of rice residue, driven by the need for timely land preparation, poses severe environmental and health consequences, including nutrient loss, greenhouse gas emissions, high concentrations of particulate matter (PM), and disruption of the ecological cycle. This study focuses on implementing effective management practices in the RWCS through tillage-based crop establishment, residue retention, and incorporation methods. The objective is to improve crop yield and its attributes by enhancing soil health properties. A split-plot experimental design was practiced with four different treatments, zero-tillage with manual harvesting (ZT), Happy Seeder with combine harvester (HS), Happy Seeder with Mulcher and combine harvesting, and conventional tillage (CT). By evaluating soil nutrient content, including organic carbon (OC), N, P, and K, at a 0–10 cm depth, the study demonstrates the superiority of the mulcher with Happy Seeder (MHS), which significantly increased soil nutrient levels by 105, 59, 102, and 97%, respectively, compared to conventional tilled broadcasted wheat (CT). Furthermore, the MHS treatment exhibited the highest yield of 56.8 q ha−1, outperforming the yield of 43.6 q ha−1 recorded under conventional tilled broadcasted wheat. These findings underscore the critical role of surface residue retention with MHS in ensuring crop productivity and overall production sustainability of the RWCS in Haryana, India. Moreover, effective rice residue management holds long-term implications for agricultural resilience, farm economics, environmental conservation, and human health. It emphasizes the importance of adopting sustainable practices, prioritizing research efforts, and advocating for policies that ensure the prolonged sustainability and productivity of the RWCS while safeguarding environmental well-being.
