Development of improved plantain/banana germplasm with black sigatoka resistance by Ortíz, R., Vuylsteke, D.R., Ferris, R.

“…The results indicated that multilocational trial are necessary to assess yield stability of plantain-banana hybrids across environments in the same agroecological zone. Two exceptional black sigatoka-resistant tetraploid clones TMPx 1658-4 and TMPx 548-9 were identified as high and stable yield genotypes. …”

Soil fertility status of cassava fields treated by integrated application of manure and NPK fertilizer in Zambia by Biratu, G.K., Elias, E., Ntawuruhunga, Pheneas

“…This research aimed to explore soil fertility status and nutrient supply capacity at different growth stages of cassava fields under combined application of organic manure and NPK fertilizers in two agroecologies of Zambia. Topsoil (0–20 cm) samples were collected from cassava fields treated with factorial combination of four levels of chicken manure (0, 1.4, 2.8, and 4.2 ton ha−1) and four levels of NPK (control, 50N-11P-41.5K, 100N-22P-83K, and 150N-33P-124.5P). …”

Climate change mitigation and agriculture by Wollenberg, Eva Karoline, Tapio-Bistrom, M.L., Grieg-Gran, M., Nihart, A

“…Climate Change Mitigation and Agriculture includes chapters about experiences in developed countries, such as Canada and Australia, where these efforts also have lessons for mitigation options for smallholders in poorer nations, as well as industrialising countries such as Brazil and China. A wide range of agroecological zones and of aspects or types of farming, including livestock, crops, fish farming, fertilizer use and agroforestry, as well as economics and finance, is included. …”

Examining the drivers of agricultural experimentation among smallholder farmers in Malawi by Hockett, M., Richardson, Robert

“…Smallholder farmers in Malawi are faced with the challenge of managing complex and dynamic farming systems while also adapting to change within volatile agroecological conditions. Moreover, management decisions are influenced by a combination of local knowledge, expert recommendations and on-farm experimentation. …”

Genotype environment interactions for cyanogenic potential in cassava by Bokanga, M., Ekanayake, I.J., Dixon, A., Porto, M.

“…The genotype-environment interactions are less pronounced but significant; some genotypes maintain the same cyanogenic potential ranking when planted in various agroecological zones, even though the absolute values of cyanogenic potential may be increased or decreased. …”

Genetic control of seed shattering during African rice domestication by Lv, S., Wu, W., Wang, M., Meyer, R.S., Ndjiondjop, M.N., Tan, L., Zhou, H., Zhang, J., Fu, Y., Cai, H., Sun, C., Wing, Rod A., Zhu, Z.

“…Functional characterization of SH3 and SH4 (another gene controlling seed shattering on chromosome 4) revealed that multiple genes can lead to a spectrum of non-shattering phenotypes, affecting other traits such as ease of threshing that may be important to tune across different agroecologies and postharvest practices. The molecular evolution analyses of SH3 and SH4 in a panel of 93 landraces provided unprecedented geographical detail of the domestication history of African rice, tracing multiple dispersals from a core heartland and introgression from local wild rice. …”

Varietal threat index for monitoring crop diversity on farms in five agro-ecological regions in India by Dulloo, Mohammad Ehsan, Estrada-Carmona, Natalia, Rana, Jai Chand, Yadav, Rashmi, Grazioli, Francesca

“…We tested the method with datasets collected from the UN-Environment GEF project implemented in India, in which data on crop and varietal diversity were collected across seven states in India, covering five agroecological regions. Results showed that landraces are still commonly grown in the study sites, especially in the central and western regions, and that more than 50% of landraces are considered threatened, suggesting that conservation interventions are required to prevent large-scale genetic erosion. …”
