- Description
- Maize is one of the most important crops grown by smallholder farmers in Amatole and O.R. Tambo Districts of the Eastern Cape. For this study, there were 13 maize varieties that were evaluated extensively by on-farm trials in selected areas under dry land and irrigated conditions. Nine were newly introduced and improved Open Pollinated Varieties (OPVs), while four were locally grown varieties. Among the locally grown varieties, one was a hybrid-check, while the remaining three were improved OPVs. The objectives of this study were: to investigate the potential marketability of newly introduced maize OPVs, identify factors influencing farmers‟ demand of improved maize OPVs and assess their profitability when compared with hybrids. One hundred and thirty seven sample households were interviewed using a structured questionnaire. The data was analyzed using descriptive statistics (frequency, percentages), gross margins and regression analyses. Data for computing gross margins was taken from the on-farm trials. Results showed that the actual production of improved maize OPVs constituted 0percent in Zanyokwe Irrigation Scheme (ZIS) and 20percent of the farmers in the O.R. Tambo District. At Silwindlala Women‟s Project (SWP), the improved maize OPV (Sahara) was grown. The majority of the farmers in the study areas were growing competitor varieties (hybrids and/or in conjunction with landraces). Results show that, there is potential market for improved maize OPVs in the Eastern Cape. The majority of the farmers, 87percent and 92percent in Amatole (SWP and ZIS) and O.R. Tambo Districts respectively, indicated that they were willing to adopt the newly introduced maize OPVs. Results showed that the hybrid PAN 6479 variety in general performed better than improved maize OPVs whereas in some areas, the improved maize OPVs had better gross margins and gross profit margins than the hybrid variety. The indicated genotypes did not show specific adaptation to selected environments. The demand model that employed a multiple regression model was used and data was analyzed using Statistical Package for the Social Science (SPSS) computer software. Results of the multiple regression model showed that household socio-economic factors (extension contact, access to credit, availability of household income, proportion of land area under cultivation, proportion of land area under (hybrids and landrace) and perceptions on seed color) and an input market factor (availability of the improved maize OPV seeds on the local shops) were the most important factors influencing farmers' decisions to demanding the improved maize OPVs. Extension contact, access to credit, level of household income and proportion of land area under cultivation, positively influenced the demand for the improved maize OPVs whereas the unavailability of the improved maize OPV seeds on the local shops, proportion of land area under hybrids and landraces and perceptions on seed color negatively influenced the demand for the improved maize OPVs.
