CA had 1.4 and 3.2 t/ha more maize yield in the second and third seasons compared to CT. In the first two seasons CT had 310, 180 and 270 kg/ha more cowpea, soybean and pigeonpea compared to CA. But CA had more groundnuts that CT in the 2nd and 3rd seasons in two other Districts. Net returns and land equivalent ratios were also calculated for each treatment and District. <http://sco.lt/6KkZPc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/7icEG8?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/80mYaG?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8IwsuO?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8b7DEW?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Rotation, Mulch and Zero Tillage Reduce Weeds in a Long-Term Conservation Agriculture Trial <http://sco.lt/8kLAxc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From www.mdpi.com <http://sco.lt/8tHXYe?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> - Today, 10:19 AM <http://sco.lt/8kLAxc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Fonteyne, S., Singh, R.G., Govaerts, B. & Verhulst, N. 2020.

This study looked at weed biomass, density and diversity with and without herbicide in a 19 year long term trial in the highlands of Mexico to evaluate the impact of the three pillars of CA on weeds. Generally weed density and biomass were lower in CA compared to CT. The three components of CA significantly reduced weed biomass that were lower when all three components were used. When herbicides were applied, weed biomass in CA was 91% lower in maize and 81% lower i wheat compared to CT. They conclude that if weeds are controlled in initial years, weed populations in CA systems are lower than CT systems. <http://sco.lt/8kLAxc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/4o5LX6?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/56FfrE?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5OQ0BM?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5gaKVU?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Pathways to intensify the utilization of conservation agriculture by African smallholder farmers <http://sco.lt/6DPSPA?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From www.cambridge.org <http://sco.lt/5ykepc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> - July 28, 12:04 PM <http://sco.lt/6DPSPA?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Brown, B., Nuberg, I. & Llewellyn, R. 2019.

Most farmers reported higher yields with CA but this was related to input intensification (mainly herbicides) and was constrained by finances. Farmers identified constraints across their physical, financial, human and informational resources for low intensities of CA. The authors suggest ways to overcome this. <http://sco.lt/6DPSPA?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/6Z5JTs?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/6rFdo0?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/79Py88?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/7RaISG?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Conservation Agriculture and Maize Production Risk: The Case of Mozambique Smallholders. <http://sco.lt/631Rrc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From doi.org <http://sco.lt/7jkcmO?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> - July 27, 11:33 AM <http://sco.lt/631Rrc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Kidane, S.M., Lambert, D.M., Eash, N.S., Roberts, R.K. & Thierfelder, C. 2019.

Net returns and risk were generated for various CA technologies. The results suggest maize yields were higher for CA systems compared to CT and also less variable. At higher elevations, direct seeding was risk-preferred compared to CT. At lower elevations, results were ambiguous and CT may be better than CA. They conclude that selecting areas for CA that are known to do well is needed before out-scaling technology transfer. <http://sco.lt/631Rrc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/81ux6W?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8K5HQe?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8cFbkm?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8uPw4u?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Tillage and crop rotations enhance populations of earthworms, termites, dung beetles and centipedes: evidence from a long-term trial in Zambia <http://sco.lt/5dpKDY?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From www.cambridge.org <http://sco.lt/9CaGP2?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> - July 23, 3:57 PM <http://sco.lt/5dpKDY?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Muoni, T., Mhlanga, B., Forkman, J., Sitali, M. & Thierfelder, C. 2019.

They looked at CT, basins, direct sowing plus sole cropping, two or three year crop rotations involving maize, cotton and sunnhemp. The data looked at earthworms, termites, dung beetles and centipedes. Biota diversity was generally higher in CA compared to CT treatments. They found that reduced tillage systems and crop rotations increase biological activity compared to CT systems. <http://sco.lt/5dpKDY?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/57O4NU?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5PYOhc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5hij1k?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5zt3Ls?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From adoption to Transformative Learning around Conservation Agriculture. <http://sco.lt/55T2Ke?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From doi.org <http://sco.lt/6I3Ng0?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> - July 23, 3:31 PM <http://sco.lt/55T2Ke?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Probst, L., Ndah, H.T., Rodrigues, P., Basch, G., Coulibaly, K. & Schuler, J. 2019.

They describe ways that that existing systems need to be improved to meet future food security challenges. The contend that the principles of CA system can provide a framework for a unified approach for improvement. They provide evidence that CA when flexibly applied and in ways that mimic the natural ecosystems is a best-bet approach. <http://sco.lt/6PV6vI?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8LDfwu?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8dO0H2?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8vYKbA?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/9DievI?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Conservation Agriculture for Rice-Based Intensive Cropping by Smallholders in the Eastern Gangetic Plain. <http://sco.lt/5qjFUO?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From www.mdpi.com <http://sco.lt/4qM8Zc?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> - July 23, 10:57 AM <http://sco.lt/5qjFUO?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Bell, R.W., Haque, E., Jahirrudin, M., Rahman, Md.

It includes agronomy, weed control, soil properties and GHG emissions. Looks mainly at multi-crop planter (locally made) attached to a 2W tractor and planting as strip-till. One pass planting reduces fuel costs by 85%, and labor by 50%. Also used the machine to transplant rice in a strip without puddling where rice yield increased up to 12% and therefore gross margins. Also used for planting lentils, mustard, maize and wheat. Weeds were controlled by using effective pre- and post-emergent herbicides and the mulch from the leftover residue from the previous crop. <http://sco.lt/5qjFUO?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5QgnDs?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5ir7Y0?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/611Rs8?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/6JBmCG?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Induced Hunger?

They do improve weed control, save labour and reduce land degradation when CA is used and they are applied properly. This study surveyed 275 households in Malawi. They find that CA promotion incentivized herbicide use and reduced weeding jobs for ganyu (local hired labor) resulting in problems finding work and affecting food security for poor people. They recommend that where alternative labour are limited, projects need to assess the impacts on social groups in terms of hunger and poverty. <http://sco.lt/6a4uR6?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/7BglAe?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/7Tr5Um?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/7m1Pou?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/84Bk92?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Combining no-till with rye (Secale cereale L.) cover crop mitigates nitrous oxide emissions without decreasing yield. <http://sco.lt/5DzF9U?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From linkinghub.elsevier.com <http://sco.lt/8MM4TA?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> - Today, 10:04 AM <http://sco.lt/5DzF9U?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Fiorini, A., Maris, S.C., Abalos, D., Amaducci, S. & Tabaglio, V. 2020.

Within NT systems rye had lower N2O emissions compared to hairy vetch as a consequence of the high C/N ratio of rye residues. <http://sco.lt/5DzF9U?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8wgj7Q?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/9Er3RY?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/4rUX5s?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/59erQ0?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Conservation Agriculture Improves Long-term Yield and Soil Quality in Irrigated Maize-oats Rotation <http://sco.lt/5MKT56?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From www.mdpi.com <http://sco.lt/5RpBk8?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> - July 28, 11:54 AM <http://sco.lt/5MKT56?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Fonteyne, S., Martinez-Gamino, M.A., Saldivia Tejeda, A. & Verhulst, N. 2019.

Diverse crop rotations included sweet potato, cassava, common bean, soybean, cowpea and pigeopea.Th effects on labor use and financial returns were measured. Over the three years of the study, continuous NT maize produced the greatest gross and net revenues, despite having higher production costs. But the diversified cropping systems were also profitable for farmers because of lower production costs. Farmgate prices for the various crops was the major factor affecting profitability.They conclude that policies that reduce input price volatility and increase farmgate prices of alternative food crops would have the greatest impact on adoption of other diverse crops. <http://sco.lt/4kBwiu?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/4scvc8?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5AnFwG?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5SxaGO?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/5l7uaW?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Conservation Agriculture in Trouble?

Glyphosate use has helped farmers control weeds, especially when using herbicide tolerant (HT) genotypes. The recent debate about the safety of Glyphosate and excessive use of chemical herbicides in food production has caused concern for farmers should this broad spectrum, easily degradable and environmentally friendly herbicide be banned. This paper estimates the costs associated with this prohibition in Spain. They conclude that a ban on Glyphosate would have a negative impact on the economic profitability of farms and also on the non-economic advantages derived from adopting CA. <http://sco.lt/7UzF68?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/6dctYu?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/6vnDt2?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/7DxYDA?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/7W7sXI?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Conservation Agriculture increases profits in an Andean Region of South America. <http://sco.lt/5572Q4?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> From doi.org <http://sco.lt/7oICrQ?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> - July 23, 11:14 AM <http://sco.lt/5572Q4?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> Delgado, J.A., Barrera, M.V.H., Escudero, L.L.O., Cartagena, A.Y.E., Alwang, J.W., Stehouwer, R.C., Tenelema, A.

In the initial phase 3 out of the 4 crops NT had the highest yields. Later, with addition of N fertilizer, yields were higher in 4 out of 5 crops not fertilized. Leaving the crop residue on the surface increased the yield of one crop. Higher net returns were found with NT compared to tillage. <http://sco.lt/5572Q4?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/86SXBY?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8OcrVg?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8gnBpo?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> <http://sco.lt/8yxW9w?_tmc=RaNLiRv5NdPKNHAL4eSkXes5M0aBG7LR8ymbYOoYZKk&track=1> ######################################################################## To unsubscribe from the CA-Cop-L list, click the following link: &*TICKET_URL(CA-Cop-L,SIGNOFF);
