Low-cost soil conservation technique for controlling gully erosion in the semi-arid area of the Free State province

In South Africa, soil erosion is a major problem confronting natural resources. Gully erosion has a huge negative impact on soil productivity and potable water supplies, while measures to control it are expensive. Sannaspos farm which has been threatened by gully erosion was selected as a demonstration site for controlling gully erosion using low-cost control measures. The main aim of this study was to control gully erosion resulting in improved rangeland production. The technique entailed the use of old tyres and bags filled with soil. Three reference points were selected along a 240 m gully in August 2016 and monitored over 42 months. After 17 months (January 2018), gully depth decreased from 70 to 34 cm, 45 to 20 cm and 35 to 19 cm at the three reference points. After 24 months (August 2018) gully depth further decreased from 34 to 27 cm, 20 to 14 cm, and 19 to 10 cm for the three points. Thirty months after installing control measures (February 2019), the gully was sealed at all reference points. By February 2020 (42 months after initiation of the trial), the entire gully was sealed and covered with various vegetation types. Use of this low-cost method to control gully erosion is recommended under similar conditions.

Determinants of professionalisation of extension service delivery: A confirmatory factor analysis approach

The need for agricultural extension services in Nigeria to attain a higher ethical and professional status of registering and certifying its service providers like other disciplines for effective service delivery has led this study to examine the factors influencing extension professionalisation in Nigeria. 356 extension agents from both public and private extension organisations were selected through a two-stage sampling procedure. A structured questionnaire was used to elicit information on the knowledge, attitude and perceptions on the effects of the components of professionalisation (i.e. accreditation, registration, and certification) on service delivery. The Cronbach alpha reliability values for the constructs used in the different sections of the instrument were knowledge (0.78), attitude (0.94), accreditation (0.92), registration (0.89) and certification (0.96). Data was analysed using IBM AMOS version 24 to conduct a confirmatory factor analysis to determine the interrelationships that exist between the extension agent’s knowledge, attitude, and the components of professionalisation. The findings revealed a significant and strong positive correlation between the constructs of the extension agent’s knowledge, attitude and the professionalisation components of accreditation, registration, and certification. These findings have implications for educating and training extension agents on professionalisation and its components to ensure its institutionalisation in the agricultural extension sector for the provision of a more ethical, competent, accountable, and efficient rural and advisory service delivery.

South African government palliative funds for agriculture amid Covid-19: Challenges of implementation and suggestions for improvements

The novel Corona virus pandemic has been extremely overwhelming at all levels causing massive economic setbacks for many countries including South Africa. The country witnessed an unprecedented scaling-down of its national economic activities, which called for an emergency response from the government. Several Covid-19 relief schemes were instituted by the government to ensure that farms of all sizes would survive. A support fund of R1.2 billion was allocated to the agriculture and food sector through the Department of Agriculture, Land Reform and Rural Development (DALRRD). The fund was primarily meant to assist financially distressed small-scale farmers to ensure continued production and food security for the country. This study collated the conditions for financial Covid-19 stimulus support required from smallholders and analysed several factors that prevented some members of this vulnerable group from benefitting from the relief funds. These factors include complexities associated with satisfactorily categorizing smallholder producers, productivity, marketing and policy challenges, glitches in formalising smallholder producer operations, the farm-business record keeping pitfall, and the exclusion of subsistent producers. The paper suggests some possible corrective measures that could allow for more inclusive support to these categories of farmers; some of which includes a simple but robust financial traceability system for the farmers, and a need to continue to push for the completion of national registration process of smallholder producers.

Appraisal of the management practices of goat farmers in selected districts of the KwaZulu-Natal province: can the extensionist play a role to improve?

The study was conducted to assess management practices by goat farmers in uMgungundlovu of the KwaZulu-Natal province. A total of 70 farmers were interviewed using structured questionnaires. A considerable number of respondents had low-level education (40%) n=28. Management activities performed by respondents included control of internal and external parasites, which was done by 94% and 96%, respectively. The most vaccinated for diseases were Pulpy kidney (61.54%) and Pasteurella (51.92%). Fifty-five respondents (78.57%) grazed their animals on the veld, while an insubstantial percentage of respondents had cultivated pastures (15.71%) n=11. Respondents provided winter and summer supplementary feed (46%) and supplementary lick (83%). A total of 17 farmers (24.29%) had a specific breeding season. Breeding management activities were done by farmers, and 5.71% of respondents tested bucks for fertility, while 18.57% provided flush feeding, and 11.43% performed pregnancy diagnosis. Most farmers who applied sound management practices reported elevated production levels.

Sustainability of conservation agriculture adoption and the role lead farmers play in Zimbabwe

Conservation Agriculture (CA) has been promoted widely in Zimbabwe through several organizations, including government and non-governmental organizations, to help address food insecurity. The sustainability of donor led interventions has been questioned as they are of limited duration, and some research has reported that farmers stop practicing CA when a project ends. However, agriculture extension services are reported crucial in adopting new agriculture technologies; hence, continued access to services is crucial for the sustainable uptake of CA. The use of farmer-led extension approaches has been used to reach more farmers at low cost to promote CA and for sustainability. The study evaluates the sustainability of CA practices as well as lead farmers roles after the end of Christian Care project activities. The findings reveal continued adoption of CA principles, albeit on a small scale. We conclude that CA has become part of the traditional farming system and recommend labour-saving technologies for the uptake of CA on a greater scale. Government extension support has also continued, although lead farmers played a minor role in these extension activities. Lead farmers alone cannot sustainably provide extension services without institutional support. The recommendation is that public extension systems work closely with lead farmers in communities to efficiently reach farmers and ensure better coordination between NGOs and government extension activities.

Review of plant health clinics: a recent phenomenon for effective plant pests and diseases diagnosis

Plant health clinic is a mechanism in which farmers are able to access basic plant healthcare and services from relevant authority in relation to infested or suspected infested plants and plant products for diagnostic purposes. Plant health clinic is an integral part of the plant health system which provides early pest diagnostic and advisory services to farmers. In this paper, it can be further defined as a basic plant healthcare rendered to farmers to enhance and improve plant production thereby diagnosing plant pests and diseases with the aim of employing appropriate pest management strategy. In many countries, plant health clinics operators are extension experts, plant doctors, inspectors and scientists within government and NGOs. Extension support in particular is critical in the operation of plant health clinics. The purpose of this paper is to provide a global overview of plant clinic as a recent ways of plant diseases diagnosis. This paper concluded that plant health clinics are valuable tools which need to be adopted by various countries for smallholder farmers to understand more about plant pests and diseases as well as management strategy. To the contrary, many countries are dependent on national diagnostic services as opposed to basic plant healthcare which is more accessible to the smallholders. This review paper further revealed that plant health clinics’ knowledge, awareness, accessibility and satisfaction of the smallholder farmers are very important. Plant clinics may not efficiently and effectively operate in the absence of the aforementioned aspects. Plant clinics were found to be the most efficient way to reach smallholder farmers for advice.

Soil fertility management for groundnut in the lowveld of Mpumalanga and north coastal plain of KwaZulu-Natal provinces of South Africa

Smallholder groundnut production contributes substantially to food security in Mpumalanga Lowveld (MLV) and in Manguzi, the northern coastal plain (NCP) of KwaZulu Natal (KZN), both of which are dominated by infertile structureless sandy soils. A study was conducted to obtain information on the chemical properties of the soils to guide fertilizer management for optimizing groundnut production on these soils. Soil samples were collected from representative sites in MLV and NCP, and analysed for pH, calcium (Ca), magnesium (Mg), potassium (K), phosphorous (P), zinc (Zn) and manganese (Mn) in the peg-zone (0-10 cm depth), root zone (10-40 cm depth) and subsoil (40-60 cm depth). The soils were largely acidic, with pH mostly falling below 5.5. The basic cation concentrations were generally low, and so were Zn and Mn concentrations. Nonetheless, with the exception of P and Mn, the soil concentrations of the other nutrients analysed were within ranges considered adequate for vegetative and reproductive growth of groundnut, though Zn was marginally so. General fertility management recommendations to inform agricultural extension are provided for groundnut production on the sandy soils based on the chemical analyses of the soils.

An assessment of climate-smart agriculture (CSA) practices skills amongst extension practitioners in South Africa

One of the roles of extension services is to link farmers to the developers of technological solutions (research outputs). Extension officers act as facilitators and assist farmers in their decision-making and technology adaptation. With the changing climate threatening production resources, extension officers need to encourage farmers to adopt various climate-smart agriculture (CSA) practices. The paper seeks to reflect on a study by the Agricultural Research Council (ARC) to assess their skills and knowledge about climate change and CSA. The study aimed to conduct a skills audit on CSA and related concepts. Through a stratified sampling method, all extension practitioners (EPs) registered with South African Council for Natural Scientific Professions (SACNASP) were included in the survey. The survey, administered through a user-friendly tool (online google forms), was developed to investigate: familiarity with, and current skills in climate-smart agriculture and collect biographic information, field of responsibility (e.g. cropping, livestock and mixed farming). Both quantitative and qualitative data was sourced through the survey tool to draw generalized conclusion and perceptions of how best to improve the capabilities of EPs on CSA. The results of the survey showed that EPs had a theoretical understanding of climate change and CSA. Generally, EPs across all positions, education levels, age categories and experience could identify the correct definition and cause of climate change, despite the fact that the majority had not received any CSA training. On the contrary, the majority of respondents had little understanding of how best to apply the CSA approach in practice, to assist farmers curb the effects of climate change. A CSA training programme was developed to establish a strong theoretical base, together with an understanding of the challenges presented by climate change and climate variability to sustainable agriculture in South Africa.

Characterization of women and youth smallholder agricultural entrepreneur’s in rural irrigation schemes in Vhembe district, South Africa

The purpose of the study was to characterize irrigated smallholder agricultural enterprises (ISAEs) in selected areas of Vhembe District, Limpopo Province. The characterization focused on the geophysical environment and on participants in ISAEs. Precipitation was at most 460mmpa for villages along Madimbo Corridor and 701-1380mmpa for those along Mutale Valley, and temperatures were 38.1℃-44.0℃ (Madimbo) and 30.0℃-40.0℃ (Mutale). Groundwater supplemented surface water and was utilized more at Madimbo Corridor compared to Mutale Valley. The study area was characterized as semi-arid to sub-humid, hence technologies for efficient irrigation should be promoted. Participants in ISAEs were female (94.9%), and adult (52.72%) with low education levels (67.7% ≤ secondary education). The majority (88.65%) were not formally employed (54.61% self-employed, 34.04% full-time farmers). Participants experienced some level of poverty, 68.03 percent received low household incomes (R1001-R5000/month), 77 percent received social grants. Interestingly, the majority (65.31%) stayed in multiple-roomed houses, had cement brick walls, and corrugated iron roofs (54.42%), and all had electricity, a stove, and a fridge. Also, majority-owned radio (96.67%), DSTV (87.45%), vehicles (65.56%), and cellphones. Participants mostly provided adequate food supply (91.84%) with three meals/day (79.38%) except during hard times where 49.56 percent provided fewer meals mostly due to delayed readiness of farm produce. Strategies to empower ISAE participants to be more effective should consider their gender, age, education, and economic status estimated by income, asset ownership, and food security.

Towards an efficient post Covid-19 ict based extension service delivery model for the sugar industry of eSwatini

This study presents a designed ICT based extension service delivery system for the sugar industry of Eswatini. The model is an improvement of the current system and it presents a delivery system that is void of many limitations. This model emanates from findings of a survey which involved all smallholder sugarcane farmers (N=172) and their extension officers (N=17). The survey investigated how information and knowledge are currently managed within the sugar industry. Basically, the model revolves around the use of mobile phones to relay information among the sugar industry stakeholders in a timely, more organised, productive and cost-effective ways, without contravention of the COVID-19 pandemic protocols. Sugarcane stakeholders can now be able to exchange information using the model without having to meet physically, which is what most of the traditional approaches required. The exchange of information can be in a form of voiced, pre-recorded information in the form of texts, audio, or audio visuals. This would go a long way in enhancing smallholder farmer’s productivity as it has the potential of empowering more rural sugarcane farmers with crucial information for improved productivity. The model has the potential to sustain itself as the participation of the stakeholders is promoted.
