The survey collected baseline data on farm households to construct indicators for measuring changes in the adoption of improved maize varieties and for assessing impact on adopting households. The main objective of the study was to understand the potential use of the drought tolerant maize (DTM) technology by farmers, provide information for policy makers, and serve as a baseline for measuring impacts of the project.

In 2006, the Drought Tolerant Maize for Africa (DTMA) project was initiated withthe aim of improving maize germplasm in the drought prone mid-altitude regions ofeastern and southern Africa (ESA). Through this project eight hybrids and four openpollinatedvarieties (OPVs) were developed through multi-location trials under optimal(well fertilized and well-watered conditions), rainfed, low soil nitrogen and manageddrought stress environments. To validate the performance of the new germplasm againstcommercially available germplasm and farmer-preferred varieties, a series of trials wereconducted across 49 farmers’ fields in eight countries in 2010/11 seasons in ESA. Trialswere un-replicated and conducted under farmer management, with farms consideredblocks in a randomized complete-block design. Average trial yields ranged from 0.7 t ha-1 to above 8 t ha-1. Trials were divided into two categories based on yield levels; high yieldingtrials >=3 t ha-1 (n = 30 trials) and low yielding trials < 3 t ha-1 (n = 19 trials). Broad senseheritability of high and low yielding trials was 0.80 and 0.62 to 0.94 and 0.61, respectively,indicating that highly repeatable means can be estimated from un-replicated on-farmtrials in ESA. The best new DTMA hybrids out-yielded the farmers’ own varieties by morethan 35% and 50% under low- and high-yield conditions, respectively, when compared to SC513, the most widely grown commercially hybrid available varieties in southern Africa.
