“…The differential in BCR might be attributed to disparities in grain yield and cultivation expenses in TA and CA, respectively, in PT and ST. Savings may be attributed to tillage, weeding, and labor expenditures required in all crops (Table 7). This conclusion is consistent with previous study, which predicted 70% [42] and 49% [43] savings in land preparation in ST and PT, respectively. The ST had the lower plowing cost (ranging from US$30.1~39.8 ha -1 ) due to reduced tillage intensity and fuel use, whereas the PT had the higher price (ranging from US$70.9~117.9 ha -1 ).…”

Power tiller-driven plow tillage and crop residue exclusionary Traditional Agriculture practices are expensive, labor demanding, soil damaging, and eco-unfriendly. Over the last several years, pursuits of crop production through sustaining the productive capacity of soils, and environmental quality, have raised concern to adopt Conservation Agriculture worldwide. Single tillage combined with herbicides and crop residue retention principles of Conservation Agriculture are being developed. Between 2016–2017 and 2017–2018, a two-year on-farm experiment was done in Bangladesh. We practiced two crop establishment methods; Traditional Agriculture: Plow tillage followed by three manual weeding without residue preservation of previous crop and Conservation Agriculture: Pre-plant herbicide + single tillage + pre-emergence herbicide + post-emergence herbicide; under rice–wheat and rice–wheat–mungbean systems. Data reveal that the Conservation Agriculture was more cost-effective crop establishment technique than Traditional Agriculture in rice, wheat, and mungbean by increasing the ratio of benefit to costs by 24.3%, 35.7% and 48.8%, respectively, with a savings in tillage operations (66.3%, 58.1%, and 57.6%, respectively), weeding expenditures (59.2%, 24.5%, and 42.2%, respectively), and manpower requirements (25.1%, 27.2%, and 31.3%, respectively). This has resulted in an increase of 32% productivity of rice–wheat–mungbean systems with the yield advantage of 16%, 31% and 37% in rice, wheat and mungbean, respectively. When mungbean was added, the rice–wheat system’s productivity rose by 43%. The rice–wheat–mungbean system under Traditional Agriculture had the highest land utilization efficiency (99.45%), followed by Conservation Agriculture (92.05%), which expanded the scope to include additional crops into rice–wheat–mungbean system. Moreover, the Conservation Agriculture had a 59.7% greater production efficiency than Traditional Agriculture, where the rice–wheat–mungbean system having the highest production efficiency (53.00 kg–1 ha–1 day–1), followed by the rice–wheat system (45.57 kg–1 ha–1 day–1).

“…Thus, SP saved around 68% cost for land preparation due to fewer tillage passes and lower fuel consumption than for CT land preparation. In one previous study, Haque and Bell [50] estimated 70% savings in land preparation for SP over CT, due to the lower land preparation cost in SP which ranged from US$ 32.54 -33.25 ha -1 ; while the land preparation cost in the case of CT corresponded to US$88.24 -110.29 ha -1 . In another study, Islam, et al [51] computed 49% of savings from the land preparation in SP over CT.…”

Rice-based intensive cropping systems require high input levels making them less profitable and vulnerable to the reduced availability of labor and water in Asia. With continuous conventional puddled rice transplanting, the situation is exacerbated by damaged soil structure, declining underground water and decreasing land and water productivity. To minimize these negative effects a range of new crop establishment practices have been developed (zero tillage, dry direct seeding, wet direct seeding, water seeding, strip planting, bed planting, non-puddled transplanting of rice, mechanical transplanting of rice crop and combinations thereof) with varying effects on soil health, crop productivity, resource saving and global warming mitigation potential. Some of these allow Conservation Agriculture (CA) to be practiced in the rice-based mono-, double- and triple cropping systems. Innovations in machinery especially for smallholder farms have supported the adoption of the new establishment techniques. Non-puddling establishment of rice together with increased crop residue retention increased soil organic carbon by 79% and total N (TN) in soil by 62% relative to conventional puddling practice. Rice establishment methods (direct seeding of rice, system of rice intensification and non-puddled transplanting of rice) improve soil health by improving the physical (reduced bulk density, increased porosity, available water content), chemical (increased phosphorus, potassium and sulphur in their available forms) and biological properties (microbiome structure, microbial biomass C and N) of the soil. Even in the first year of its practice, the non-puddled transplanting method of rice establishment and CA practices for other crops increase the productivity of the rice-based cropping systems. Estimates suggest global warming potential (GWP) (the overall net effect) can be reduced by a quarter by replacing conventional puddling of rice by direct-seeded rice in the Indo-Gangetic Plains for the rice-based cropping system. Moreover, non-puddled transplanting of rice saves 35% of the net life cycle greenhouse gases (GHGs) compared with the conventional practice by a combination of decreasing greenhouse gases emissions from soil and increasing soil organic carbon (SOC). Though the system of rice intensification decreases net GHG emission, the practice releases 1.5 times greater N2O due to the increased soil aeration. There is no single rice establishment technology that is superior to others in all circumstances, rather a range of effective technologies that can be applied to different agro-climates, demography and farm typologies.
