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 ...
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) ...
Effects of conservation agriculture on soil quality and productivity in contrasting agro-ecological environments of Zimbabwe
Experimentation by farmers with conservation agriculture (CA) is increasing in southern Africa, but local longer term data on these new production systems are scarce. This study focuses on CA research at two contrasting ...
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 ...
Farmers' taxonomies as a participatory diagnostic tool : soil fertility management in Chihota, Zimbabwe
Soil infertility is a major constraint to food production in the communal areas of Zimbabwe. Smallholders in the region recognise the problems of low soil fertility and have devised ways of coping with them. This study ...
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, ...
