“…Horticulture is an important sector because it contributes to food and nutrition security, household income, employment, and foreign exchange in Sub-Saharan Africa (SSA) (Frank et al, 2019;Amao, 2020;Ebert, 2020;Minten et al, 2020). Vegetables, such as tomatoes, kales, and French beans, are high-value crops grown in most African countries including Kenya (van der Lans et al, 2012;Cernansk, 2015;Nordey et al, 2017).…”

Black Soldier Fly-Composted Organic Fertilizer Enhances Growth, Yield, and Nutrient Quality of Three Key Vegetable Crops in Sub-Saharan Africa

Worldwide, French beans (Phaseolus vulgaris L.), tomato (Solanum lycopersicum L.), and kales (Brassica oleracea L. var. acephala) are considered economically important food crops. There is a rapid decline in their yield due to severe soil degradation. Thus, high commercial fertilizer inputs are crucial, though they remain expensive and inaccessible to resource poor farmers. We investigated the comparative performance of composted black soldier fly frass fertilizer (BSFFF), conventionally composted brewer's spent grain (BSG), commercial organic fertilizer (Evergrow), and mineral [nitrogen, phosphorus, and potassium (NPK)] fertilizer on growth, yield, N use efficiency, and nutritional quality (crude protein, crude fiber, crude fats, ash, and carbohydrate concentrations) of tomatoes, kales, and French beans under greenhouse and open-field conditions for two seasons. The fertilizers were applied at rates equivalent to 371 kg of N ha−1. For each crop, the plots were treated with sole rates of BSFFF, BSG, Evergrow, and NPK to supply 100% of the N required. Additional treatments included a combination of BSFFF and NPK, and BSG and NPK so that each fertilizer supplies 50% of the N required. The control treatment consisted of unfertilized soil. Results show that vegetable yields achieved using a combination of BSFFF and NPK were 4.5, 2.4, and 5.4-folds higher than the yield from the control treatment for tomatoes, kales, and French beans, respectively. The combined application of BSFFF and NPK produced 22–135%, 20–27%, and 38–50% higher yields than sole NPK for tomatoes, kales, and French beans, respectively, under both greenhouse and open-field conditions. The highest agronomic N use efficiency was achieved in sole BSFFF-treated plots compared to sole BSG and Evergrow. The N taken up by the vegetables was significantly higher when BSFFF and NPK were integrated. Vegetables grown using a combination of BSFFF and NPK had the highest crude protein and ash concentrations. Our findings demonstrate that the integration of BSFFF and NPK in vegetable cropping systems at the recommended rate of 1.24 t ha−1 BSFFF and 322 kg ha−1 NPK would improve soil health, boost yield, and nutritional quality of vegetable crops.

“…Horticulture farming has been identi ed as one of the agricultural sub-sectors that is expanding quickly and a potential driver of poverty reduction for low-income smallholder households (Mkindi, 2011; Barrett et al, 2012). Horticultural crops refer to fruits, vegetables, ornamental and medicinal plants (Amao, 2019). Avocado is one of the horticultural crops with high economic value.…”

Food insecurity is an enduring, critical challenge in Ethiopia. Linking farmers to high-value markets continue to be a viable option for breaking the food insecurity. Many studies have emphasized on factors determining smallholders’ participation in high value markets. Despite their undeniable importance, these studies have methodological limitations since they neglected the importance of this for food security. Thus, this study aimed to fill a knowledge gap in the area by investigating the factors influencing smallholder avocado farmers’ participation in a high-value market channels and how it impacts households' food security in the study area. This study employed a cross-sectional research design and multistage sampling techniques to achieve the objectives of the study. Both primary and secondary data were collected. The primary data were collected from randomly selected 389 avocado producers using a semi structured questionnaire. Secondary data were collected from journals, annual reports, websites and different published and unpublished materials. Descriptive statistics, inferential statistics, and propensity score matching model were used to analyze the data. The result of the binary logit model revealed that the participation of avocado producers in a high-value market channels was influenced by age, educational status, the quantity of avocados sold, and price of avocado in quintal and market information. The ATT estimation of PSM model indicated that the participation in high-value market channels had a positive and significant influence on the food security in the study area. Given the substantial contributions participation in the high-value market channels to food security, concerned bodies in Ethiopia should encourage more households to participate in the high-value market channels.

“…Horticulture farming has been identified as one of Tanzania's rapidly expanding agricultural subsectors and has the potential to significantly reduce poverty among low-income smallholder households (Malekela, 2022). Fruits, vegetables, ornamental plants, and medicinal plants are all part of horticultural farming (Amao, 2019). There are many distinct avocado kinds farmed around the world, but Hass and Fuerte variants are the most common (Rincon-Patino, Lasso, & Corrales, 2018).…”

This article aimed at gaining understanding of avocado farming among household farmers in Tanzania, in particular in Njombe Urban. Specifically, the article assessed on who and how decisions are made in households about farm utilization in general and avocado farming in particular. In methodology, the article adopted a cross-sectional research design with both quantitative and qualitative approach. Data were collected by using questionnaire to 75 smallholder farmers, and in-depth interview to 5 actors of avocado farming (Avo Africa organization). Analysis of the study was done descriptively, whereas frequency and percentage were used, however inferential analysis involved bivariate analysis with chi-square (X2). The qualitative data analysis was done by using content analysis. The study found that decision making made in households for farm utilization is affected by how and who makes decision on income use from avocado farming, plot size for farming, farm activities or tasks and type of crops to be farmed as most decisions are made by Men. The study concluded that decision making on avocado farming in household have a low or unequal level of decisionmaking on all aspects of avocado growing at the household level. Which leads to bias where mostly decisions are made by men and women are implementers of the decisions made. It is recommended that local government authorities especially sector of agriculture should deliver seminars in local community to emphasize the households to avoid bias in decision making concerning agricultural activities.
