“…This shows that the rice plant received nitrogen from organic sources gradually and that it could be available at lower doses than synthetic fertilizer, which is commonly available. These findings confirm ( Goutami et al, 2018 ; Jana, Mondal & Mallick, 2020 ; Nataraja et al, 2021 ). Adequate dietary sources promoted post-anthesis dry matter accumulation (DMA) in grain ( Iqbal et al, 2020 ; Wu et al, 2021 ).…”

Background The sustainability of paddy production systems in South Asia has recently been affected by a decline in soil health and excessive water usage. As a response to the global energy crisis, escalating costs of synthetic fertilisers, and growing environmental concerns, the utilization of organic plant-nutrient sources has gained considerable attention. Emerging adaptation technologies, including conservation tillage and innovative approaches to fertilizer management, present practical choices that can significantly contribute to the long-term preservation of soil fertility. Methods The two year-long field experiment was completed in sandy loam soil during rainy (Kharif) seasons in 2019 and 2020 at the crop research centre farm of Sardar Vallabhbhai Patel University of Agricultural & Technology, Meerut, Uttar Pradesh to analyze the impacts of different tillage establishment of the crop and its methodologies as well as integrated nutritional management approaches on rice growth, yield, productivity of water, nutrient uptake, and fertility status of soil under a rice-wheat rotation system. The experiment was set up in a factorial randomized block design and replicated three times in a semi-arid subtropical environment. Results The conventionally transplanted rice puddled (CT-TPR) grew substantially better taller plants, and higher dry matter buildup leads to increased yields than transplanted rice under raised wide bed (WBed-TPR). WBed-TPR plots had more tillers, LAI, CGR, RGR, and yield characteristics of the rice in two year study. CT-TPR increased grain yield by 4.39 and 4.03% over WBed-TPR in 2019 and 2020, while WBed-TPR produced the highest water productivity (0.44 kg m−3) than CT-TPR, respectively. The 100% RDF+ ZnSO4 25 kg ha−1 + FYM (5 t ha−1) + PSB (5 kg ha−1) + Azotobacter 20 kg ha−1 (N6) treatment outperformed the other fertiliser management practices in terms of crop growth parameters, yields of grain (4,903 and 5,018 kg ha−1), nutrient uptake and NPK availability, organic soil carbon. Among the fertilizer management practices, with the direct applications of the recommended dose of fertilizer (RDF), farm yard manure (FYM), phosphate solubilizing bacteria (PSB), Azatobactor and zinc worked synergistically and increased grain yields by 53.4, 51.3, 47.9 and 46.2% over their respective control treatment. Conclusions To enhance rice productivity and promote soil health, the study suggests that adopting conservation tillage-based establishment practices and implementing effective fertilizer management techniques could serve as practical alternatives. It is concluded that the rice yield was improved by the inclusive use of inorganic fertiliser and organic manure (FYM). Additionally, the study observed that the combination of conventional puddled transplanted rice (CT-TPR) and N6 nitrogen application resulted in enhanced rice crop productivity and improved soil health.

The increased dependence of farmers on chemical fertilizers poses a risk to soil fertility and ecosystem stability. Plant growth‐promoting rhizobacteria (PGPR) are at the forefront of sustainable agriculture, providing multiple benefits for the enhancement of crop production and soil health. Bacillus subtilis is a common PGPR in soil that plays a key role in conferring biotic and abiotic stress tolerance to plants by induced systemic resistance (ISR), biofilm formation and lipopeptide production. As a part of bioremediating technologies, Bacillus spp. can purify metal contaminated soil. It acts as a potent denitrifying agent in agroecosystems while improving the carbon sequestration process when applied in a regulated concentration. Although it harbours several antibiotic resistance genes (ARGs), it can reduce the horizontal transfer of ARGs during manure composting by modifying the genetic makeup of existing microbiota. In some instances, it affects the beneficial microbes of the rhizosphere. External inoculation of B. subtilis has both positive and negative impacts on the endophytic and semi‐synthetic microbial community. Soil texture, type, pH and bacterial concentration play a crucial role in the regulation of all these processes. Soil amendments and microbial consortia of Bacillus produced by microbial engineering could be used to lessen the negative effect on soil microbial diversity. The complex plant–microbe interactions could be decoded using transcriptomics, proteomics, metabolomics and epigenomics strategies which would be beneficial for both crop productivity and the well‐being of soil microbiota. Bacillus subtilis has more positive attributes similar to the character of Dr. Jekyll and some negative attributes on plant growth, soil health and the environment akin to the character of Mr. Hyde.

“…Comparable increases in organic carbon, available N, P and K through addition of organic materials was also reported (Carpenter-Boggs 2000 and Melero et al 2008). Superior soil fertility status on organic farms compared to soils fertilized with chemical fertilizers was also reported by Mader et al 2002and Nataraja et al 2021. Rasool et al (2007 observed that the average mean weight diameter (MW D), total porosity and water holding capacity (WHC) were highest in FYM treated plots both in rice (0.237 mm) and wheat (0.249 mm).…”

Background: Considering the importance of organic farming and growing demand for organically produced foods, field studies were conducted for 14 kharif years (2007 to 2020) on a black clayey vertisol soil at Regional Agricultural Research Station, Nandyal, India to study the influence of organic and conventional farming systems on productivity, grain quality, soil health and economic returns of super fine rice variety BPT-5204. Methods: The experiment was laid out in non replicated two block design with each block of an area of 2000 m2 each. The organic plot was green manured with Dhaincha (Sesbania aculeata) and FYM @ 10 t ha-1, Castor cake and Neem cake were applied @ 500 kg ha-1 as basal dose of manure and topdressing of vermicompost was added as a nutrient sources. In in-organic plot, 100% RDF (240:80:80 kg NPK ha-1) was applied. Result: The pooled mean grain yield of paddy grown in vertisols under K.C. Canal ayacut under organic farming treatment was 4.04 t/ha while it was 5.6 t ha-1 under control (Inorganic/Conventional farming) and the straw yield also was 5.07 t ha-1 under organic farming and 7.96 t ha-1 under control. The average yield increase in in organic plot was 27% and for straw it was 35%.The Organic carbon status was highest in organic plot (0.60%) when compared to the inorganic plot (0.36%).
