Resistance Based Integrated Pest Management Strategy for Globodera rostochiensis and Globodera pallida in Potato Cropping Systems
(2019-10)
Potato cyst nematodes (PCN), Globodera rostochiensis and G. pallida are important potato pests responsible for high yield losses globally. The ability of PCN to persist in the soil for a long time makes their management challenging and therefore these nematodes are under strict quarantine regulations in many countries. Nevertheless, both PCN species have recently been reported in potato cropping systems in Kenya. Resistant potato cultivars reduce nematode densities in the field below damage threshold levels and thus ...

Farm and farmer capital foster adoption of improved quality agrochemical inputs in the cotton-wheat zone of the Punjab, Pakistan
(2019-12-23)
Adoption of yield-enhancing agricultural inputs fosters agricultural intensification in low-income countries. In Pakistan, initial adoption of agrochemicals is already widespread; the low quality of much of the inputs contributes to severe health, environmental and enduring pest problems, however. While the positive influence of farm capital and farmer capital on initial adoption is well documented, the adoption of improved quality inputs is little researched. We reduce the knowledge gap investigating smallholder ...

Climate-smart agriculture policy and (in)justice for smallholders in developing countries
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-06-05)
The Food and Agriculture Organization of the United Nations developed the term Climate-Smart Agriculture as an approach to transform agricultural systems to support development and ensure food security in a changing climate. This paper analyses whether climate-smart agriculture policy meets the demands of climate justice and respects the rights of smallholders; and if not, how it could be amended. The study is based on a literature review supplemented by four interviews with climate-smart agriculture actors from ...

Manure application effects on nitrogen pools in a subtropical soil of Oman
(2019-04)
Agricultural productivity of the millennia-old oasis agriculture in Oman is based on the continuous application of high rates of goat and sheep manure combined with flood irrigation. The high nitrogen (N) and carbon (C) turnover in these systems is a result of year-around high temperatures and continuous soil moisture, but knowledge is lacking on how N and C are transformed under these conditions. Therefore, this study aimed at investigating the N movement in different soil N pools. To this end a field experiment was ...
