Abstract:
An experiment on Influence of Conservation Agriculture on soil microbial indices contributing to soil carbon sequestration in rice–wheat cropping system was conducted during 2018– 20 at the research farm of the Indian Agricultural Research Institute (IARI), New Delhi, India. The treatments included: 1. Zero tillage (ZT) 100% N, 2. ZT 100%N + Brown manuring (BM), 3. ZT100%N +CR, 4. ZT100%N +CR+BM, 5. ZT100%N + Mungbean (MB), 6. ZT100%N +MB +CR, 7. Conventional transplanted rice (CTR) – zero tillage wheat (ZTW) 100%N, 8. CT 100%N. The 16:1w5c content (Arbuscular mycorrhizal fungi), 18:1w Hydroxy 9c content (Gram-negative bacteria) was maximum in ZT +CR+BM. CTR – ZTW had higher monounsaturated fatty acids, (MUFA) in rice crops. ZT had lower polyunsaturated fatty acids (PUFA) content (Saprotrophic fungi), 18:2w6,9c content (Saprotrophic fungi) and higher straight organism, branched organism, 18:1w9c content (Cyanobacteria; green algae), 10-methyl content (Actinomycetes, Actinobacteria), biomass. ZT+BM had higher straight organism, Cyclo organism (Gram-negative bacteria), 16:1w5c content (Arbuscular mycorrhizal fungi), biomass, and lower branched organism (Gram-positive bacteria), monounsaturated fatty acids, (MUFA), polyunsaturated fatty acids (PUFA) content (Saprotrophic fungi), DMA content, 18:1w9c content (Cyanobacteria; green algae), 18:2w6,9c content (Saprotrophic fungi), 10-methyl content (Actinomycetes, Actinobacteria) in rice crop. ZT+CR had higher straight organism, Cyclo organism (Gram-negative bacteria), DMA content, 10-methyl content (Actinomycetes, Actinobacteria), 16:1w5c content (Arbuscular mycorrhizal fungi), biomass, and lower branched organism, monounsaturated fatty acids, (MUFA), polyunsaturated fatty acids (PUFA) content (Saprotrophic fungi), 18:1w9c content (Cyanobacteria; green algae), 18:2w6,9c content (Saprotrophic fungi) in rice crop. ZT+MB had higher straight organism, 16:1w5c content (Arbuscular mycorrhizal fungi), and lower branched organism, monounsaturated fatty acids, (MUFA), polyunsaturated fatty acids (PUFA) content (Saprotrophic fungi), DMA content, 18:1w9c content (Cyanobacteria; green algae), 18:2w6,9c content (Saprotrophic fungi), 10-methyl content (Actinomycetes, Actinobacteria), biomass in rice crop.
