Conservation agriculture systems for Malawian smallholder farmers: long term effects on crop productivity, profitability and soil quality
Conservation agriculture (CA) systems are based upon minimal soil disturbance; crop residue retention and crop rotation and/or intercrop association are increasingly seen to recycle nutrients, increase yield and reduce ...
Profitable and sustainable nutrient management systems for East and Southern African smallholder farming systems: challenges and opportunities: a synthesis of the Eastern and Southern Africa situation in terms of past experiences, present and future opportunities in promoting nutrients use in Africa
(CIAT; The University of Queensland; QAAFI; CIMMYT, 2013)
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 ...
Risk and maize-based cropping systems for smallholder Malawi farmers using conservation agriculture technologies
Agricultural production in southern Africa is constrained by numerous factors, including low soil fertility, frequent droughts and flooding, limited access to fertilizers and the use of unsustainable management techniques ...
Conservation agriculture for increasing maize yield in vulnerable production systems in central Mozambique
Smallholder farming under rainfed low input crop production in central Mozambique is characterised by decline in soil fertility, low yields and risks of crop failure. To revert this situation, conservation agriculture (CA) ...
Integration of conservation agriculture in smallholder farming systems of southern Africa: identification of key entry points
A component-omission experiment based on the principle of conservation agriculture (CA) was established on smallholder farms for three seasons in Murehwa and Hwedza districts, Zimbabwe; Barue district in Mozambique; Balaka ...
Weed control in conservation agriculture systems of Zimbabwe: Identifying economical best strategies
Weed management under conservation agriculture (CA), especially when manually controlled is one of the major setbacks for the widespread adoption of CA in southern Africa. This study was conducted at three on-station and ...
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, ...
