“…The activity and biomass of the microbes play a key role in enhancing soil quality/health [59], as these respond to soil and crop management practices [60]. The bacterial and fungal populations are compared in the INM-treated plot compared to the inorganic-treated plot [61]. The bacterial population increased by approximately 60%, whereas the fungal population almost doubled in the INM system in comparison with the IORA.…”

Over years of intensive cultivation and imbalanced fertilizer use, the soils of the Indiansubcontinent have become deficient in several nutrients and are impoverished in organic matter.Recently, this region has started emphasizing a shift from inorganic to organic farming to managesoil health. However, owing to the steadily increasing demands for food by the overgrowingpopulations of this region, a complete shift to an organic farming system is not possible. The rice–wheat cropping system (RWCS) is in crisis because of falling or static yields. The nations of thisregion have already recognized this problem and have modified farming systems towardintegrated nutrient management (INM) practices. The INM concept aims to design farmingsystems to ensure sustainability by improving soil health, while securing food for the populationby improving crop productivity. Therefore, this paper was synthesized to quantify the impact androle of INM in improving crop productivity and sustainability of the RWCS in the context of theIndian subcontinent through meta-analysis using 338 paired data during the period of 1989–2016.The meta-analysis of the whole data for rice and wheat showed a positive increase in the grainyield of both crops with the use of INM over inorganic fertilizers only (IORA), organic fertilizersonly (ORA), and control (no fertilizers; CO) treatments. The increase in grain yield was significantat p < 0.05 for rice in INM over ORA and CO treatments. For wheat, the increase in grain yield wassignificant at p < 0.05 in INM over IORA, ORA, and CO treatments. The yield differences in theINM treatment over IORA were 0.05 and 0.13 Mg ha−1, respectively, in rice and wheat crops. Thepercent yield increases in INM treatment over IORA, ORA, and CO treatments were 2.52, 29.2, and90.9, respectively, in loamy soil and 0.60, 24.9, and 93.7, respectively, in clayey soil. The net returnsincreased by 121% (INM vs. CO) in rice, and 9.34% (INM vs. IORA) and 127% (INM vs. CO) inwheat crop. Use of integrated nutrient management had a positive effect on soil properties ascompared to other nutrient management options. Overall, the yield gain and maintenance of soilhealth due to INM practices over other nutrient management practices in RWCS can be a viablenutrient management option in the Indian subcontinent.

“…The long term application of various organic manure leads to increase soil organic carbon, which generally served as a source of energy for biological activity, thereby enhancing the density of microbes in organic applied treatments (Moharana et al, 2012). Kuttimani et al (2017) revealed that the fungal population had a positive correlation with addition of organic sources of nutrients in the treatments. Overall, most of the soil microorganisms are chemo-autotrophs, which require organic source of carbon as food and oxidation of organic substances provides energy which might be the reason in improving microbial population in soils applied with organics (Ingle et al, 2014).…”

We analyzed data from a long-term rice-potato-groundnut cropping sequence to evaluate the effects of different nutrient management practices on yield trends, economics and soil fertility of the system. In this study, most of the organic and integrated treatments showed significantly higher mean system yield in terms of rice-equivalent yield (REY) of the 13th and 14th crop cyclethan that of with purely inorganic source. Highest mean rice-equivalent system yieldwas obtained in the treatment with 33% of recommended N each from FYM, vermicompost and Neem cake along with Azospirillum, Azotobacter, Rhizobium and PSB (14.96 t ha-1). In contrast with the yield result, purely inorganic treatment showed better performance compare to all other organic and integrated treatments from the economical point of view during last two 13th and 14 th cropping year. The organic nutrient-management packages increased the mean soil organic carbon and soil macronutrients (available N, P and K) at the end of 13th and 14 th cropping system cycle over the control (fallow land) and the buildup was maximum in the soil, applied with 33% of recommended N each from FYM, vermicompost and Neem cake along with Azospirillum, Azotobacter, Rhizobium and PSB (0.98%, 301.8, 61.1 and 173.3 kg/ha for organic carbon, N, P and K). The mean microbial population after thirteenth and fourteenth cropping year in terms of colony forming units increased in a higher rate in soils with organic nutrient supply system (bacteria 3.7 to 14.5 cfu g-1, fungi 3 to 12.3 cfu g-1) compared to the control as against the respective increases of 1.2 cfu g-1 and 1.8 cfu g-1 in the soils receiving nutrients through chemical fertilizers. Application of 33% of recommended N each from FYM, vermicompost and Neem cake along with Azospirillum, Azotobacter, Rhizobium and PSB was the best organic nutrient management practice compare to other studied management practices for rice–potato–groundnut cropping system in new alluvial zone of West

“…The integrated nutrient modules would be superior in obtaining higher net profit and on par benefit: cost ratio as compared to the control treatment (100% RDF + FYM). Kuttimani et al, (2013b) reported that, higher gross returns of Rs. 3,63,85,600/-was recorded during 2010-11 and 2011-12 respectively with the application of 100 per cent recommended dose of fertilizer along with 40 % Wellgro soil and the net return was higher (Rs.…”
