Thesis (MTech (Agriculture))--Cape Peninsula University of Technology, 2015. / A study was carried out at Bien Donné Experimental Farm, near Paarl in the Western Cape Region (South Africa), to evaluate the performance of solid winery waste compost (WWC) and inorganic fertilizer (N:P:K, 2:3:4 (30) - 5g Zn%) on growth and yield of cabbage (Brassica oleracea var. capitata L.) and Swiss chard (Beta vulgaris subsp. cycla). The experimental plot was fertilized as per treatment with WWC (100% and 400% equivalent recommended fertilizer application using N as reference mineral) and inorganic fertilizer. The experimental design was set up in a Randomized Complete Block Design (RCBD) with 4 treatments (control- without compost and inorganic fertilizers, inorganic fertilizer-2:3:4 (30) - 5g Zn% and LAN (28), WWC application at different application rates were (3485g/plot) (100%) and (13939g/plot) (400%)) replicated four times. Soil analysis showed that the experimental plot is dominated by sandy soil structure. Results of mineral analysis after application of treatments showed a significant (p>0.05) drop in soil pH over time in the untreated control and application of 400% WWC significantly (p<0.05) raised soil pH compared with the control. The application of mineral fertilizer showed significant (p<0.05) increase in soil P compared with the other treatments. However, WWC picked up significant (p<0.05) speed above inorganic fertilizer, thus making P available to the soil than NPK mineral fertilizer. A significant (p<0.05) drop in soil K content by 21% over time on amended soil with inorganic fertilizer treatment was observed. However, the application of WWC at 300 and 400% significantly (p<0.05) raised the soil K by 54.93 and 73.06% respectively. There were no significant differences in soil Ca over time, but high soil Ca concentrations from WWC (100%) were recorded compared to inorganic treatment that showed the lowest soil Ca concentration. There was a slight drop in soil Na over time in control and soil amended with inorganic fertilizer. The effects of the treatment on Mg values were not so prominent, suggesting that concentrations of nutrients are less essential characteristics of the soil or small portion of nutrients were readily available on the soil.

There are thousands of different wine brands available and wineries have to build a relationship with their customers, a relationship that will create a long-lasting experience. The relationship starts with the first interaction they have with the winery (Alonso et al 2008:978). Visitors to the tasting room create the opportunity to build long-term relationships (O’Neill & Charters 2000:113; Nowak & Newton 2006:157), build and develop brand loyalty (Dodd & Gustafson 1997:43), increase wine sales (Gilinsky et al 2003:18), and improve cash flow (Jago & Issaverdis 2001:18). The subject of repurchasing intentions in the wine industry has attracted the attention of numerous researchers; in particular, the connection between winery visits, brand loyalty and post-visit consumer behaviour (Nella & Christou 2010:2). Nederburg is one of the most prestigious South African wine estates, with a deep-rooted history in South Africa as one of the biggest wine brands. It is 100% owned by wine and spirits giant Distell and presents an ideal case for investigating the influence of the relationship between quality, customer satisfaction and price on repurchasing intentions in the South African wine industry. The purpose of this research was to determine whether the tasting room experience, in combination with a quality product, good pricing and customer-focused operations, leads to higher customer satisfaction and repurchase intentions. The present study indicates that the South African wine industry faces many challenges but it also highlights the various opportunities there are for wine estates to not only increase their sales but also to build long-lasting relationships with consumers. The study concludes with recommendations to the South African wine industry on how to improve their tasting room environment so that they can benefit from the relationship between wine quality, wine price, customer satisfaction and repurchasing intentions.
