In order to minimize duplication, consolidate resources and strengthen industry representation to government, the South African Avocado Growers Association (SAAGA), South African Litchi Growers Association (SALGA), South African Macadamia Growers Association (SAMAC) and the South African Mango Growers Association (SAMGA); amalgamated under an umbrella organization called Subtrop. This study focuses on the pre and post effect the amalgamation had on Extension services to the abovementioned organizations. The effect was measured by conducting a survey. The survey measured both Subtrop member and relevant Subtrop staff responses. The survey used two questionnaire types, one for Subtrop members and one for Subtrop extension advisors. The questionnaires were designed to complement the SPPS V19.0® statistical package. The questionnaires were completed at group interview sessions. A total of 127 farmer respondents, divided in two groups, namely 90 farmer respondents and 37 opinion leader respondents participated in the external survey. The internal survey comprised of six Subtrop extension advisor respondents. Farmer and opinion leader respondents, (hereafter called respondents), provided their perceptions and rated the extension services of the technical department of Subtrop. Results showed that the respondents used the Extension services for on farm advice and group based Extension services like study groups. The Subtrop Extension services received a higher rating after the Subtrop amalgamation than before the amalgamation. Subtrop extension advisor responses showed a need for training and coaching, as well as some reconciliation with respect to the increase in work load afforded by the amalgamation. Pre-amalgamation extension advisors served one commodity, while post amalgamation extension advisors now serve four commodities. The respondents indicated their satisfaction with the organizing of study groups. They also indicated that the study groups met their needs. Although the respondents understood the value of intercommunication and participation, the study showed that the minority realized the need to take ownership of study groups. All the extension advisors indicated that organizing study groups was the single activity that used most of their time. The Subtrop study groups were rated higher after the Subtrop amalgamation than before. The Subtrop newsletters were rated higher after the Subtrop amalgamation. The respondents indicated the newsletters as valuable and therefore proved newsletters as an appropriate extension communication tool. The Subtrop websites were indicated as somewhat valuable. Most respondents indicated a lack of awareness of the websites, indicating a need to promote the websites better. Although very few respondents completed the marketing related services section of the survey, those that completed this section were all aware of this service. The following recommendations emerged: For extension advisors: <ul> <li> The development of a curriculum of Subtrop commodities for training purposes;</li> <li> Regular technical and soft-skill training;</li> <li> The development of a mentorship program; and</li> <li> For new extension advisors an orientation program which includes the above mentioned.</li> </ul> To improve the Extension service outputs: programmed extension and the implementation of area committees. Additional focus on communication and exit interviews. For farmer members: <ul> <li> Study group management needs to be improved, combine newsletters, improve awareness of research and promote websites and market services.</li> <li> Further: develop an extension policy, maximize area committee involvement and regular member feedback surveys.</li></ul> / Dissertation (MSc)--University of Pretoria, 2012. / Agricultural Economics, Extension and Rural Development / unrestricted

The aim of the research presented in this dissertation was to further the implementation of push-pull for control of Eldana saccharina on sugarcane in the Midlands North region, KwaZulu-Natal, South Africa. Eldana saccharina, an indigenous stem borer, is the most damaging pest of sugarcane in South Africa, and sustainable control has still not been achieved. The push-pull strategy, a form of habitat management, has been developed for E. saccharina and is recommended as part of an integrated pest management (IPM) approach. Implementation of this strategy for both large- and small-scale farmers was facilitated through mixed methods social research. It included a novel exploratory network analysis to understand the process of technology adoption by farmers. Surveys showed that large-scale farmers have a good knowledge of E. saccharina, IPM and push-pull but that they needed more practical knowledge for implementation of the strategy. Farmers recommended experiential learning opportunities such as field days and model farms to get to know more about this technology. Despite demonstrating a positive attitude towards push-pull, farmers perceived it to be a ‘hassle’ and this is potentially the biggest barrier to its adoption. However, with suitable learning opportunities for farmers and good support for planting inputs, implementation of push-pull is likely to succeed. Sugarcane was shown to play an important role in the livelihoods and farming systems of small-scale growers. They did not perceive E. saccharina as a serious production constraint and had poor knowledge of the pest and its control. Extension for small-scale growers in this region should focus primarily on weed management and on reducing input costs, but still raising awareness of the increasing threat of E. saccharina. On-farm push-pull field trials showed a significant reduction of E. saccharina damage on two farms. Mean percentage damaged internodes decreased from 4.1% to 2.7% and from 1.7% to 1.1% in the presence of the repellent grass species, Melinis minutiflora. Where farmers did not manage their crops well, push-pull was not effective. It is therefore crucial that push-pull within an IPM framework be implemented together with good crop management practices. Stem borer surveys in wetlands on sugarcane farms revealed a high diversity of indigenous stem borers and parasitoids, including a stem borer species, Pirateolea piscator, which may pose a threat to crops in the future. These findings, together with a literature review on the significance of on-farm biodiversity and ecosystem services, demonstrated the value which wetlands have for pest management on sugarcane farms. Wetland health assessments were used to develop a tool for farmers to assess and utilise the wetlands on their farms for improved management of E. saccharina. This study highlights the importance of a farmer-participatory approach to implementation of knowledge-intensive farming practices such as push-pull. The importance of wetlands for providing pest regulatory services on sugarcane farms has shown that environmental sustainability needs to become a fundamental principle of farming and agricultural research. Participatory implementation of push-pull, as recommended in this dissertation, could act as a driving force for agroecology in the South African sugar industry and move sustainable farming practices off the pages of journals and manuals onto farmers’ fields. / Thesis (MSc (Zoology))--North-West University, Potchefstroom Campus, 2013
