Rainfall risk and the potential of reduced tillage systems to conserve soil water in semi-arid cropping systems of southern Africa
(AIMS Press, 2016)
Improvement of household food security in the Limpopo Basin has been elusive due to a combination of factors related to information and market constraints, but also farmers’ risk aversion induced by the high variability ...
Effect of different mulching materials on maize growth and yield in conservation agriculture systems of sub-humid Zimbabwe
(AIMS Press, 2016)
The introduction of conservation agriculture (CA) for smallholders increased the competition for crop residues between crop and livestock enterprises of the mixed smallholder farming system. Smallholders practicing CA have ...
Evidence and lessons learned from Long-Term On-Farm Research on Conservation Agriculture Systems in communities in Malawi and Zimbabwe
A long-term study was carried out in the Zidyana Extension Planning Area (EPA), Malawi and in the Zimuto Communal Area, Zimbabwe, to evaluate the effect of different conservation agriculture (CA) systems on crop productivity, ...
Response of maize (Zea mays L.) secondary growth parameters to conservation agriculture and conventional tillage systems in Zimbabwe
(Canadian Center of Science and Education, 2016)
Previous, research focused mainly on the effects of conservation agriculture (CA) and conventional practices (CP) on crop yield mostly. A study was conducted at five sites in Zimbabwe from 2012 to 2014 to investigate effects ...
A short-term assessment of carbon dioxide fluxes under contrasting agricultural and soil management practices in Zimbabwe
(Canadian Center of Science and Education, 2015)
Two of the biggest problems facing humankind are feeding an exponentially growing human population and preventing the accumulation of atmospheric greenhouse gases and its climate change consequences. Refined agricultural ...
Soil fertility management effects on maize productivity and grain zinc content in smallholder farming systems of Zimbabwe
Background and aims: Low soil zinc (Zn) threatens crop production and food nutrition in most cereal-based cropping systems in Africa. Agronomic management options that include farmers' locally available organic nutrient ...
A comparative analysis of conservation agriculture systems: Benefits and challenges of rotations and intercropping in Zimbabwe
Increasing soil degradation in southern Africa and the potentially negative effects of climate change demand ?greener? solutions to reverse this trend. Conservation agriculture (CA) has been proposed as one of those solutions ...
An African success: the case of conservation agriculture in Zimbabwe
This paper highlights the limiting factors of agricultural production in Zimbabwe and presents conservation agriculture (CA) as a potential solution to address many of these challenges. CA, based on the three principles ...
Investigating Conservation Agriculture (CA) Systems in Zambia and Zimbabwe to Mitigate Future Effects of Climate Change
Most models predict that climate change will affect the southern African region both through temperature rises and increased frequency and severity of drought. Conservation agriculture (CA) based on minimal soil disturbance, ...
Failing to yield? ploughs, conservation agriculture and the problem of agricultural intensification: an example from the Zambezi Valley, Zimbabwe
Agricultural intensification, or increasing yield, has been a persistent theme in policy interventions in African smallholder agriculture. This article focuses on two hegemonic policy models of such intensification: (1) ...
