The study aimed to investigate the hygiene quality of fresh agricultural produce, irrigation water and compost from four cooperatives (Jabulani, Nungwane, Senzakahle and Siyazenzela) supplying the uMbumbulu Agri-Hub Non-Governmental Organisation. In addition, the influence that socio-economic characteristics such as age, gender, level of education and training had on the uMbumbulu farmers’ hygienic practices was investigated. Questionnaires, key informant interviews and laboratory analysis were used to collect data. The most probable number (MPN) method, a microbiological technique, was used to quantify selected hygiene indicators (i.e. total and faecal coliforms including Escherichia coli) from compost, irrigation water and leafy vegetables (spinach and lettuce) during the months of October, November and December 2011. Microbiological analysis on lettuce and spinach produced by the four Agri-Hub cooperatives confirmed that these vegetables were safe to eat and unlikely to cause sickness. The irrigation water sources, vegetables and compost faecal coliform levels met national standards with faecal coliforms of <1 000 MPN/100ml for irrigation and<200 MPN/g for the leafy salad vegetables. Compost faecal coliform levels were <1000/g and E. coli levels of <30 MPN/g, these levels decreased over the 3 months. Descriptive statistics such as the Chi-Square test using IBM SPSS and a logistic regression was performed using the STATA 11 software. The sample consisted of 60% female and 40% males, most of which (73%) were above the age of 40. A total of 60% of respondents received income from farming activities, receiving revenues of between R150- R250 a week. The logistic regression indicated that farmers already receiving some income from farming activities and those that had received training on hygienic farming practices were likely to wash hands and equipment prior to entering the field compared to those who had not. These variables influenced the hygienic practices with a probability of 26% and 32% respectively at 5% significance level. The logistic regression also showed that respondents with primary or no formal education were less likely to wash hands and equipment prior to entering the field compared to those who had a secondary level education. This unlikelihood had a probability of 35% for primary education and 43% for farmers with no formal education at significance levels of 5% and 10% respectively. This study indicates how training, education and farming experience are important and effective tools in implementing good hygienic practices in small-scale farming. The study’s main recommendations are that policies encourage farmer awareness on their responsibility of producing vegetables that are of good hygienic quality, especially if such produce is to reach the market. Furthermore policies should advocate for small-scale farmer training. This training should not be limited to subsistence farming but should also aim at preparing farmers towards accessing produce markets. Farmer training in hygienic practices should aid farmers to meet the stringent market standards allowing for better access, the regular income from such activities support farming as a livelihood and bearer of food security. It must also be noted that farmers require support in attaining the various resources needed in order to successfully and continually supply markets. / Thesis (M.Sc.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

In the past, the indigenous knowledge of soils of small-scale farmers in South Africa has been largely ignored in scientific research. Hence the use of scientific approaches to land evaluation has often failed to improve land use in rural areas where understanding of the prescriptive scientific logic is lacking. Despite this, it is clear that local people and smallscale farmers have knowledge of their lands based on soil and land characteristics that remain largely unknown to the scientific community. It is therefore important for researchers to understand farmers’ knowledge of soil classification and management. To address this issue, a study was conducted in the uMbumbulu area of KwaZulu-Natal to investigate the use of indigenous knowledge as well as farmers’ perceptions and assessments of soil fertility. A preliminary questionnaire was designed to explore indigenous knowledge in a group interview that was conducted prior to the study. Another questionnaire was used to elicit indigenous knowledge from 59 randomly chosen homesteads representative of the population of Ezigeni and Ogagwini villages. Six homesteads were chosen for further detailed information on the cropping history, knowledge specific to the cultivated lands, detailed soil description and fertility. Soil samples were taken from these homesteads under different land uses (taro, fallow, veld and vegetable) at 0-30 and 30-60 cm depth for laboratory analysis. This was done to determine the effect of land use on soil physical and chemical properties and soil microbial activity. For scientific evaluation a general purpose free soil survey was conducted to produce land capability and suitability maps. Farmers identified ten soil types using soil morphological characteristics, mainly soil colour and texture. These soil properties were also used in the farmers’ land suitability assessment. In addition, slope position, natural vegetation and village location were used to indicate land suitability. The amount of topsoil was also used in land evaluation. However, slope position was considered the most important factor as it affects the pattern of soils and hence their suitability. Soils on the footslope were considered more suitable for crops than those found on the midslope and upslope. The yield difference observed between villages, which were higher in Ogagwini than Ezigeni, was also used as a criterion for evaluation. Farmers attributed these yield differences for various crops to the effect of soil type on productivity. In support, scientific evaluation found that Ezigeni village had a number of soils with a heavy textured, pedocutanic B horizon and hence a relatively shallow effective rooting depth. Moreover, the Ezigeni village land suitability was limited in places by poor drainage and stoniness. These limitations were rarely found for the Ogagwini village soils. Farmers had a total of six comprehensive and well defined soil fertility indicators, namely crop yield, crop appearance, natural vegetation, soil texture, soil colour and presence of mesofauna. Results showed that farmers’ fertility perceptions are more holistic than those of researchers. However, despite this, their assessment correlated with soil analysis. There was a close relationship between scientific and indigenous suitability evaluation for three commonly cultivated crops (taro, maize and dry beans). This was further substantiated by yield measurements which were significantly higher for Ogagwini as rated by both farmers and scientific evaluation as the more suitable. The significant agreements between the scientific and indigenous approaches imply that there are fundamental similarities between them. Recognizing this and subsequently integrating the two approaches will produce land use plans relevant and profitable for both small-scale farmers and scientists. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.

Lack of effective storage facilities to mitigate post harvest losses threatens the profitability of organic farming. In rural KwaZulu-Natal, small scale farmers use traditional storage and sequential harvesting to keep potatoes post maturity while waiting to sell. The effect of these practices on potato quality has not been studied and documented. This study set out to investigate if traditional practices (sequential harvesting and traditional farmer’s store) of the Ezemvelo Farmers Organisation in Umbumbulu affect the quality and marketable quantity of organically grown potatoes. Specifically the study set to investigate the effect of traditional farmer’s store, in situ and controlled storage on the carbohydrate content and sensory quality of potatoes organically grown in Embo by EFO farmers; determine consumer quality expectations of organically and conventionally grown potatoes; investigate the effect of sequential harvesting on the potato quality expectations of consumers and to investigate the produce and income losses experienced by small scale organic farmers at harvest and during storage. Experiments were conducted to compare the effect of sequential harvesting, farmer’s store and controlled cold storage (7oC and 90% relative humidity) on the sensory, appearance and keeping quality of organically grown potatoes. A survey of 100 consumers (40 organic and 60 conventional consumers) was conducted to ascertain consumer appearance and keeping quality expectations of potatoes. In addition, a survey of 101 farmers investigated the storage practices of the EFO farmers who grew potatoes and the type of losses incurred in storage. Preference ranking was used to investigate if time of harvesting post maturity affected potato quality. Produce losses experienced by the farmers were quantified. A co-research group of three seasoned farmers of the EFO participated in the research. They produced potatoes used in the study and provided valuable input to ensure that the study adhered to storage practices of the farmers. The lowest and highest sugar levels were observed in potatoes stored in situ and under controlled conditions, respectively. Potatoes left in situ also recorded higher starch content. Potatoes stored in situ were significantly preferred by sensory panellists (p<0.05) over those stored in both farmer’s store and in controlled storage. Preference rank scores were negatively correlated to total sugar content and positively correlated to starch content. Consumers in the study highlighted five desirable appearance qualities in potatoes: absence of greening, absence of sprouting, smooth skin texture, absence of blemishes and light skin colour. No significant differences in the quality expectations between participating organic and conventional potato consumers were found. The majority of consumers expected potatoes to store for at least three weeks post purchase. Sequentially harvested potatoes met this expectation when potatoes were left in situ for a maximum of six weeks post maturity. Potatoes in situ also maintained good appearance and sensory quality. The highest produce losses were experienced in summer owing to soft rot problems. Production in the drier seasons (autumn and winter) increased the proportions of potatoes too small to be sold as table potatoes. With the exception of completely rotten potatoes, poor quality potatoes were consumed, used as seed potatoes and sold to the local market as seed and for food. Poor potato quality resulted in reduced income for the farmers. This investigation pioneered research into the effect of sequential harvesting on the quality of organically grown potatoes. The findings demonstrate that sequential harvesting provides resource-poor small scale organic farmers with an efficient storage option where other storage methods and technologies may be inappropriate, ineffective or unaffordable. It is recommended that government and other players in the agricultural sector plan initiatives to educate small scale potato farmers on the benefits of sequential harvesting as an effective short term method of potato storage. Research with other potato cultivars in different agro-ecological settings is needed to optimise sequential harvesting. Government policy aimed at training and developing farmer capacity in organic seed potatoes production is essential to ensure that farmers access disease and pest free seed. Farmers also need assistance to access to irrigation resources to improve production. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2009.

For the majority of rural people, agricultural activities continue to be one of their main livelihood strategies. Production of food crops is not dependent on any formally acquired knowledge of farming but is solely based on indigenous agricultural knowledge passed from generation to generation through experience and careful observations. Resource-poor farmers, especially in rural areas, follow traditional farming methods to produce their food crops and these are specifically tailored to suit their environments. Embo is located in rural KwaZulu-Natal and falls under Mkhambathini municipality. The area is characterised by small-holder farmers who are mainly Ezemvelo Farmers Organisation (EFO) members. The purpose of this study was to review the farming practices followed by farmers in respect of food crop production and secondly to understand what influences the continual practice of such farming practices among rural farming communities of Embo in KwaZulu-Natal especially the EFO farmers. The study looked at what farmers see as traditional agriculture. A combination of qualitative and quantitative methods was used for the study. Data collection methods included participatory observations, semi structured face-to-face interviews and focus group discussions. The study found that farmers are happy to follow traditional farming methods to produce their food crops. Traditional farming tools such as the hoe and animal traction are the main implements used to prepare land. Household members are the main source of farm labour with men mainly responsible for ploughing activities while the bulk of planting, weeding and harvesting activities is the responsibility of women. Cropping patterns include intercropping and crop rotation with common crops being amadumbe, beans, maize and sweet potatoes. The majority of these crops are produced for both subsistence and commercial reasons. Amadumbe is an important commercial crop produced organically. Crop protection against pests is done through traditional methods where farmers mix some concoctions made from locally available resource in order to minimise losses. Kraal manure is the main soil fertility strategy followed by farmers. Landrace seeds are the main seed type used by the farmers. Local seed sources include own production and asking from other farmers. Crops with good qualities are selected in fields and maintained as seeds, which are then stored separate from those for home consumption. Harvesting is mainly done manually and for important crops such as tubers with short shelf lives, harvested through piecemeal methods. Farmers are able to generate some income from their efforts and this contributes to local economies and household food security. Farmers value their farming methods and see their farming as efficient despite challenges. There is a need to consider developing labour support groups in order to ease the burden of labour especially by women. In view of the importance of traditional farming in the lives of rural people, it is important that agricultural scientists and extension officers take into consideration the knowledge farmers already have so as to develop technologies suitable for farmers’ environments. / Thesis (M.Soc.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2008.
