A global dataset for crop production under conventional tillage and no tillage systems
TL;DR: In this paper, a global dataset comparing the crop yields obtained under conventional and no-tillage systems is presented, which can help to gain insight into the main drivers explaining the variability of the productivity of NT and the consequence of its adoption on crop yields.

Abstract: No tillage (NT) is often presented as a means to grow crops with positive environmental externalities, such as enhanced carbon sequestration, improved soil quality, reduced soil erosion, and increased biodiversity. However, whether NT systems are as productive as those relying on conventional tillage (CT) is a controversial issue, fraught by a high variability over time and space. Here, we expand existing datasets to include the results of the most recent field experiments, and we produce a global dataset comparing the crop yields obtained under CT and NT systems. In addition to crop yield, our dataset also reports information on crop growing season, management practices, soil characteristics and key climate parameters throughout the experimental year. The final dataset contains 4403 paired yield observations between 1980 and 2017 for eight major staple crops in 50 countries. This dataset can help to gain insight into the main drivers explaining the variability of the productivity of NT and the consequence of its adoption on crop yields.

What is Wrong with No Tillage System?
David Kwaw-Mensah
- 07 Jan 2022
TL;DR: The concept of no-tillage as the planting of crops with minimum soil disturbance after harvesting previous crops has been used by indigenous cultures in ancient times as discussed by the authors , which represents an agricultural management system that mitigates soil erosion, decreases production input costs, and sustains long-term crop productivity.
Effect of Reduced Nitrogen Fertilization on the Chemical and Biological Traits of Soils under Maize Crops
Agnieszka Wolińska,Artur Banach,Anna Kruczyńska,Anna Sochaczewska,Weronika Goraj,Andrzej Górski,Jacek Podlewski,Andrzej Słomczewski,Agnieszka Kuźniar +8 more
TL;DR: A 20% reduction in nitrogen fertilization is sufficient to maintain soil chemical features and fertility in monoculture maize cultivation under no-tillage and traditional plowing systems.
Strip Tillage Improves Productivity of Direct-Seeded Oilseed Rape (Brassica napus) in Rice–Oilseed Rape Rotation Systems
Chaosu Li,Ming Li,Tao Xiong,Zhiguo Zhou,Xiaoqin Peng,Yong Wang,Haiyan Qin,Haojie Li,Yi-hua Tang,Gaoqiong Fan +9 more
TL;DR: Strip tillage improves oilseed rape productivity in rice-oilseed rape rotation systems by enhancing seedling growth, reducing energy consumption, and adjusting soil moisture, resulting in a 6% yield increase and reduced weed density.
Potential long-term, global effects of enhancing the domestic terrestrial carbon sink in the United States through no-till and cover cropping
Maridee Weber,Marshall Wise,Patrick Lamers,Yong Wang,Greg Avery,Kendalynn A. Morris,James A. Edmonds +6 more
TL;DR: No-till and cover cropping practices in the US could provide carbon offsets, but may have negative impacts on agricultural exports and land use patterns globally.

Occurrence of the potent mutagens 2- nitrobenzanthrone and 3-nitrobenzanthrone in fine airborne particles
TL;DR: In the present study, 2-NBA, 3-NBA and selected PAHs and Nitro-PAHs were determined in fine particle samples collected in a bus station and an outdoor site, showing low cancer risk incidence and incremental lifetime cancer risk (ILCR) calculated for both places.

Efficient generation of mouse models of human diseases via ABE- and BE-mediated base editing
Zhen Liu,Zongyang Lu,Guang Yang,Shisheng Huang,Guanglei Li,S. M. Feng,Yajing Liu,Jianan Li,Wenxia Yu,Yu Zhang,Jia Chen,Qiang Sun,Xingxu Huang,Xingxu Huang +13 more
TL;DR: In vivo generation of mouse models carrying clinically relevant mutations using C→T and A→G editors is demonstrated, making it feasible to model and potentially cure relevant genetic diseases.
Inheritance of fusarium wilts (Fusarium oxysporum F. sp. phaseoli) resistance in climbing beans.
TL;DR: Resistance to fusarium wilt is conditioned by a single highly heritable major dominant gene and can be achieved by backcross breeding and recommend a breeding strategy to introduce resistance into susceptible cultivars.
Does elevated CO2 affect the biological aspects of Liriomyza sativae in melon plants
Jéssica de Oliveira Santos,Francislene Angelotti,Tiago Cardoso da Costa-Lima,Embrapa Semiárido +3 more
TL;DR: The increase in CO2 concentration prolongs the duration of the immature stages of L. sativae; however, it does not affect their viability; and adult survival, fertility, and feeding punctures were also unmodified by the environment enriched with CO2.
