Effects of agricultural mechanization on smallholders and their self-selection into farming: An insight from the Nepal Terai by Takeshima, Hiroyuki, Shrestha, Rudra Bahadur, Kaphle, Basu Dev, Karkee, Madhab, Pokhrel, Suroj, Kumar, Anjani

“…Using samples from the Terai zone—one of the agroecological belts in Nepal, largely consisting of lowland plains— from the Nepal Living Standards Survey, we assess whether the benefits of hiring in tractor services are greater among medium to large farmers than among smallholders, and how these benefits may depend on smallholders’ decision to remain in or leave farming. …”

Soil fertility in mixed crop-livestock farming systems of Punjab, Pakistan: The role of institutional factors and sustainable land management practices by Sheikh, Asjad Tariq, Chaudhary, Ashok Kumar, Mufti, Samaa, Davies, Stephen, Rola-Rubzen, Maria Fay

“…OBJECTIVE We investigate the relationship among socioeconomic and institutional factors, adoption of sustainable land management practices, and the resulting changes in soil fertility between 2016 and 2019 within the context of mixed crop-livestock farms in the three irrigated agroecological zones of Punjab, Pakistan. A household survey was conducted in 2019 to complement soil attributes data collected by the Government of Punjab in 2016. …”

Dry direct-seeded and broadcast rice: a profitable and climate-smart alternative to puddled transplanted aus rice in Bangladesh by Ahmed, Sharif, Kumar, Virender, Asad Uz Zaman, Dewan, Mahbubur Rahman, Amina Khatun, Hossain, M. Khaled, Singh, Sudhanshu, Timsina, Jagadish, Krupnik, Timothy J.

“…Methods: We conducted multilocation and multi-year trials comparing the performance of spring ‘aus’ season rice establishment methods (machine drilled DSR, broadcasted DSR, and PTR) using three rice varieties (BRRI dhan83, BRRI dhan85, and Binadhan-19) under three landscape positions (highland, medium highland, and lowland) in three distinct districts and agroecological zones of Bangladesh. We evaluated productivity, profitability, energy use efficiency (EUE), energy productivity (EP), GWP, and yield-scaled emissions of each of these tillage and crop establishment systems. …”

Doubled-up legume rotations improve soil fertility and maintain productivity under variable conditions in maize-based cropping systems in Malawi by Smith, A., Snapp, Sieglinde S., Dimes, John P., Chikowo, Regis

“…We used the calibrated APSIM model to investigate the performance of DLR and other maize-based systems across 26 growing seasons (1979–2005) in the three agroecologies. We simulated two DLR systems (maize rotated with a groundnut/pigeonpea or soybean/pigeonpea intercrop), maize rotated with groundnut or soybean, maize intercropped with pigeonpea, and continuous maize under a range of N fertilizer inputs. …”

Improving food security and income and enhancing farmers' livelihoods in Cameroon through the introduction and promotion of improved cassava germplasm by Njukwe, E., Nguenkam, A., Mbairanodji, A., Ngue-Bissa, T., Hanna, R.

“…More than 200 high yielding cassava varieties, with a range of resistance principally to CMD and suitability for Typhlodromalus aripo, the principal biological control agent of cassava green mite, were introduced into Cameroon from IITA headquarters in Ibadan, Nigeria for testing under several agroecological conditions across Cameroon. At present, five TMS varieties (92/0057, 92/0067, 92/0326, 96/0023, and 96/1414) have been retained on the basis of their high root yield (>20t/ha), high dry matter content (>35%), high CMD resistance, and a combination of suitability to predatory mites (92/0057, 92/0067, and 92/0326), and resistance to CAD and tolerance to ARTS (96/0023). …”
