Domboshawa Training Centre Conservation Agriculture Long-term Trial
This experiment has been added by the GLTEN Curators using existing published sources.
To evaluate the long-term conservation agriculture systems to understand its effects on climate adaptation, productivity and sustainability over time.
Part of a comparison trial. The research stations that hosted the experiments were this one Domboshawa Training Centre (DTC) in Zimbabwe, Henderson Research Station (HRS) and ; Monze Farmer Training Centre (MFTC), Msekera Research Station (MRS) in Zambia; Chitedze Research Station (CRS) in Malawi; and Sussundenga Research Station (SRS) in Mozambique.
Commercial medium maturing maize varieties are planted at each experimental site with different target plant populations according to the agro-ecological recommendations. Maize varieties changed every 3–5 years to keep track with genetic yield gain provided by the seed companies. This strategy follows farmer’s practice who also change varieties periodically. Legumes and non-leguminous varieties in all experiments were planted using local seed recommendations and plant populations. Mineral fertilizer was applied as both basal and top-dressing to the maize while weed control was achieved either through manual weeding or herbicide application.
