Does the use of atrazine in maize grown under conservation agriculture adversely affect soybean productivity in maize-soyabean rotation in Zimbabwe?
(Canadian Center of Science and Education, 2014)
Weed management challenges in the early years of conservation agriculture (CA) adoption may require the use of herbicides for farmers to realise the immediate benefits of CA practices. The objective of this study was to ...
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 ...
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 ...
Comparative performance of conservation agriculture and current smallholder farming practices in semi-arid Zimbabwe
Conservationagriculture (CA) is currently promoted in sub-humid and semi-arid areas of sub-Saharan Africa as a means to increase crop water use efficiency and stabilize yields. In this study, conducted during three consecutive ...
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 ...
Effects of conservation agriculture techniques on infiltration and soil water content in Zambia and Zimbabwe
The adoption of cropping systems (CA), based on minimal soil movement, permanent soil cover with crop residues or growing plants and crop rotation has advanced rapidly in the Americas and Australia over the last three ...
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 ...
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 ...
Evidence and lessons learned from Long-Term On-Farm Research on Conservation Agriculture Systems in communities in Malawi and Zimbabwe
(MDPI AG, 2015)
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, ...
