DU TOIT, A.P.N. e NEMADODZI, E.A.. Evaluation of the appropriateness of certain grain production technologies for small-scale farmers. S Afr. Jnl. Agric. Ext. [online]. 2008, vol.37, n.1, pp.132-143. ISSN 2413-3221.
The paper suggests a combination of both modern, high-input technologies and low-input technologies in a context based technology development approach. These technologies are: improved maize varieties; row planting; legumes in the cropping system; reduced tillage practices and weed control. Although some adaptations are needed, none of the innovations in the program failed the test of appropriateness completely. According to the findings Open Pollinated Varieties (OPV's), although intensively promoted, were only preferred by 35% of the farmers while hybrid seed was preferred by 59% of the farmers. The majority of farmers (63%) indicated that they do plant maize in rows with a mechanised planter; despite high labour costs 59% of farmers still control weeds by hand and 61% of the respondents do realise the economic advantage of reduced tillage practices but still does not implement the practices. The strong linkages between all role players and active farmer participation are probably the most important reasons for the fact that farmers are still enthusiastic and eager to continue with the program.
