Lettuce (Lactuca sativa L.) is one of the widely used salad vegetable in Swaziland. However, there is a dearth of information pertaining to organic lettuce production. An experiment was conducted in a lath house at the Horticulture farm, Luyengo Campus of the University of Swaziland to assess the effects of organic fertilizers on yield and quality of lettuce grown in river sand. The organic fertilizers used were (a) bounce back compost, (b) cattle manure and(c) chicken manure. The rates of application were 40 tones per hectare (t/ha) for chicken and cattle manures, 1.5 t/ha basal dressing and 1.0 t/ha side dressing for bounce back compost. Inorganic fertilizers 2:3:2 (22) + 0.5 % zinc (Zn) and limestone ammonium nitrate (LAN 28%) were included at specific application rates of 955 kg/ha basal dressing and 100 kg/ha side dressing as control. The results showed that type of fertilizer applied significantly (P< 0.05) affected growth, yield and nutritional quality of lettuce. A trend in superiority of the different types of organic fertilizers was observed as the chicken manure exhibited relatively higher values on number of leaves, plant height, marketable yield and mean leaf dry mass. Cattle manure was second, and then bounce back compost and lastly the inorganic fertilizers. However, plants produced by bounce back compost were higher in calcium, iron and Zn contents on fresh mass basis while plants produced by cattle manure followed, and then inorganic fertilizers and lastly chicken manure. Organoleptic tests showed that there were no significant (P> 0.05) differences in appearance and taste among treatments. Results of this experiment showed that inorganic fertilizers were less suitable in lettuce production in river sand when compared to organic fertilizers. It is recommended that lettuce can be grown successfully using organic fertilizers.
Agriculture is the main anchor of the Eswatini economy and profitability in this sector still remains vital for sustainable development of the economy. This study investigated the factors affecting profitability of smallholder vegetable farmers in the Shiselweni region. Primary data was obtained using a structured questionnaire and personal interviews from 60 vegetable farmers. Data was analyzed using descriptive statistics, enterprise budget, profitability ratios and multiple linear regression models. The SPSS software was used. The results showed that the mean age of the vegetable farmers was found to be 50.5 years, the mean household size was 8 people, mean farming experience was 3 years, mean farm size was 3 hectares and the majority of the farmers had high school education. The net income of smallholder vegetable farmers was E5810.30. The results of the multiple linear regression analysis revealed that land size, gender, household size, had a direct relationship with profitability of vegetable production while age, education, experience, income and labour had a negative relationship. Farmers requested that the subsidized farm inputs should arrive on time, new engines be bought for them and dams be constructed to generate irrigation water in winter.
Indigenous fruit and nut tree crops are very important to the human diet and subsequent food security and income generation in the Kingdom of Eswatini. Indigenous fruits and nuts are important for the nutritional contribution as sources of Vitamins and minerals. They also provide fibre which is essential for proper digestion of food. Fruits, particularly nuts provide man with unsaturated fats which are good for the heat and the cardio vascular system. Indigenous fruits and nuts are aesthetic as they provide interesting colour, texture and variety. Despite the immense benefits of indigenous fruits and nuts to the people of the Kingdom of Eswatini, there has not been enough effort put towards domesticating the indigenous fruit and nut trees and subsequent commercialising their products. The objective of this paper was to document strategies towards domestication and commercialisation of indigenous fruits and nuts for improved livelihoods of Emaswati citizens, which in turn will help achieve sustainable development goals (SDGs) pertaining to human health and food security in the Kingdom of Eswatini. It can be concluded that domesticating indigenous fruit and nut trees can be achieved through a multi-stakeholder involvement. Domestication can also help in conservation of indigenous fruit and nut trees. Value addition on indigenous fruits and nuts can generate more income.
