Plantain mycorrhization with native consortium of arbuscular mycorrhizal fungi (AMF) induce solubilisation of metals (Fe2+ and Al3+) in soil from Azaguié (south-east of Côte d’Ivoire)
(2023-04-28)
New agroecological practices propose to manage soil fertility using soil microorganisms such as arbuscular mycorrhizal fungi (AMF). However, few studies have been conducted on the impact of plantain mycorrhization and metal (Fe²+ and Al³+) solubilisation in soil. This study evaluates the effectiveness of native AMF on plantain growth and metal leaching from soil. Trap plants (maize, sorghum and cowpea) were grown to produce various inoculums. Then, plantains were grown under controlled conditions, with six treatments ...

Contribution of dairy goat farming to household dietary diversity among smallholder farmers in the Central Highlands of Kenya
(2023-02-21)
In Kenya, dairy goat farming has highly been practiced for food provision and as an income-generating enterprise. However, there is scanty information on the contribution of dairy goat farming to the quality of diets consumed at household level especially among rural smallholder farmers. This study therefore analysed the contribution of dairy goat farming to household dietary diversity of the smallholder farmers. Data was collected at the end of the wet season (April-May) from a sample of 385 households in Kirinyaga ...

Small-scale farmers’ coping strategies to extreme weather events in Upper Guinea
(2023-03-06)
Extreme weather events pose a serious threat to subsistence farming and food security in Upper Guinea, where most farmers rely heavily on rain-fed agriculture. Following crop failures, farmers use what is available to them to try to maintain household food security. This paper investigated the coping strategies chosen by farmers in Upper Guinea and the motivating factors behind them. A multistage sampling method was used to select a purposive random sample of 1,500 farm households within nine selected livelihood zones ...

Characterisation of the lactation curve of Gyr and Sardo Negro cattle
(2023-07)
The objectives were to characterize the lactation curves (LC) of tropical Gyr and Sardo Negro (SN) cattle from Mexico for the design of breeding and management programs for these breeds. A total of 3561 records of 504 lactations and 3927 records of 449 lactations were used for Gyr and SN, respectively. Three lactation lengths (LL) were evaluated, namely 240 (240d), 270 (270d), and 300 (300d) days, with five non-linear models (NLM): Wood, Wiltmink, Cobby, Brody, and Sikka. Milk production was obtained at the beginning ...

Intervention options for small-scale family poultry development in south-eastern Madagascar: an expert survey
(2023-03-14)
The diets of resource-poor farmers in the Atsimo Atsinanana (AA) region of south-eastern Madagascar have limited diversity and are low in animal protein. Although poultry farming is widespread, productivity is low, and consumption of eggs is uncommon. To enable effective development interventions targeting poultry value chains, this study pursues two goals: (i) to describe current challenges in small-scale poultry rearing and egg consumption in AA, and (ii) to explore viable options for promoting poultry production. ...

Essay zur Enttabuisierung von Klassismus
(2023)
Klassismus ist eine der wenigen Diskriminierungsformen, gegen die innerhalb Deutschlands, aber auch innerhalb der EU rechtlich nicht angegangen werden kann. Was die Thematisierung von klassistischen Diskriminierungen erschwert ist, dass diese überwiegend maskiert und häufig sprachlos erscheinen. Dabei mag Klassismus zwar verschwiegen sein, aber den-noch äußerst vielfältig auftreten und wirkt institutionell wie gesellschaftlich stark verwurzelt. Es geht bei dem Phänomen nicht alleine um Diskriminierung aufgrund einer ...

Exploring inclusiveness of vulnerable and marginalized people in the cassava value chain in the Lake Region, Kenya
(2023-03-21)
Vulnerable and marginalised groups (VMGs) who comprise widows, orphans, people living with disability and HIV, have not been given sufficient attention in agriculture in sub-Saharan Africa (SSA) by policy makers, development partners, research, and extension, yet they comprise nearly one-quarter of all smallholder farmers. This study explored inclusion of VMGs in cassava value chain in the Lake Region of Kenya. Formal survey, focus group discussions (FGD), and key informant interviews (KIIs) were used to collect data ...

Economic evaluation of biological nitrogen fixation in flooded rice cultivation in subtropical lowlands
(2023-06-13)
This study aimed to assess the economic viability of biological nitrogen fixation in flood rice cultivation in subtropical lowlands. A field experiment of seven treatments was carried out during the cropping seasons 2015/16, 2017/18, 2018/19 and 2019/20 at the Lowland Experimental Station of Embrapa, in Pelotas, RS, Brazil. The evaluated treatments were: (1) negative control (without N and inoculant); (2) positive control with recommended N-fertilization (120 kg N ha-¹, without inoculant) (standard recommendation); ...

Effect of Fermentation on the bioactive compound of cocoa Beans: a systematic review and meta-analysis approach
(2023-05-30)
Several studies have found the effect of cocoa bean fermentation on bioactive compounds through various fermentation characteristics; however, none of these studies adopted the meta-analysis approach. The effect of cocoa bean fermentation on six bioactive compounds: epicatechin, catechin, total phenolic content (TPC), anthocyanins, theobromine, and caffeine were systematically reviewed. This study aims to determine which variables that can affect the loss of bioactive compounds during fermentation so that their ...

Identification of fungal pathogens causing postharvest rot of bulb onions (Allium cepa L.) in selected major growing regions of Kenya
(2023-06-27)
Rot is a major cause of bulb onion losses in Kenya, accounting for about 14 % of total postharvest losses. In Kenya, the fungi associated with bulb onion postharvest rot of onion postharvest rots are not well known. Therefore, this study aimed at identifying the fungal pathogens contributing to bulb onion postharvest rot in major growing regions of Kenya. Bulb onion samples were collected from seven major markets and isolates were obtained by cutting 3 mm tissue segments from the edges of rotten lesions. These were ...
