Litter characteristics of pine shavings, bio-secure pine shavings and sunflower hulls and its impact on broiler performance
(2021-02-22)
The aim of this study was to investigate the physical characteristics of three litter materials, namely pine shavings (PS), bio-secure, fumigated pine shavings (BS) and sunflower hulls (SH) and its influence on broiler performance over a 33-day production cycle. The experiment was conducted in commercial poultry houses holding 42,500 chicks each, utilising a randomised block design with six house replicates per treatment. Litter samples were collected weekly for analyses of moisture, water-holding capacity, bulk ...

A review of soil fertility management communication in sub-Saharan Afrika
(2021-02-12)
In sub-Saharan Africa (SSA), declining soil fertility is among the factors a ecting optimal food production. Although a number of interventions have been implemented to improve soil fertility management (SFM) in SSA, their adoption especially among small scale farmers has been low. Although the literature provides considerable evidence of socioeconomic factors which influence adoption, the subject of how communication influences adoption of SFM remains under-explored. This paper therefore reviewed studies on SFM ...

Determinants of protected tomato production technologies among smallholder peri-urban producers in Kiambu, Kenya
(2021-03-05)
Climate variability and the rise in incidences of pests and diseases continue to undermine production of high value vegetables among smallholder farmers in sub-Saharan Africa. In order to respond to these challenges, protected farming technologies (PFT) (such as greenhouses) which modify the plant environment and therefore aid in avoiding the harmful eects of climatic factors have been promoted. Greenhouses protect the crops against high solar radiation and heavy rainfall that have the potential of destroying vulnerable ...

Socio-economic aspects of irrigation agriculture as livelihood for rural families in Brazil’s semi-arid northeast
(2019-12-04)
Along the lower-middle São Francisco River, in the semi-arid region of northeast Brazil, irrigated agriculture contributes to reduce rural poverty. In the framework of the Itaparica Reservoir construction, three irrigation schemes were implemented in the Pernambuco state to compensate the local population for flooded land. Despite favourable production conditions for irrigated agriculture, many smallholders in the irrigation schemes are facing poverty. To identify socio-economic key indicators on farm income, expert ...

Dependency and economic benefits of use of wild food plants use among tribal communities in Malai Madeshawara Hills wildlife sanctuary, Southern India
(2021-01-31)
Wild food plant resources and their indigenous knowledge of use, are in danger of being lost in areas where rapid environmental and cultural transformations have led to changes in eating habits and practices. The study assesses the dependency and economic value of wild food plant use among forest-dwelling communities. Community perceptions are used to assess the use patterns and interrelations of human well-being. The data is collected through a combination of semi-structured interviews, household questionnaire survey, ...

Thailand’s maize seed market structure, conduct, performance
(2020-06-13)
Seed is one of the fastest-growing industries in agricultural sector, and maize seed industry in Thailand is one of the most developed and most advanced industries compared to other developing countries. The success of maize seed industry in Thailand is due to public and international organizations’ contributions in building infrastructure for research and promoting the role of the private sector in the industry during the early years, and a long-term commitment of investment in research and development by private ...

Effects of salicylic acid, putrescine and moring leaf extract application on storability, quality attributes and bioactive compounds of plum cv. 'Golden Japan'
(2020-07-30)
Background: Plum fruits constitute a good source of natural antioxidant substances. Particularly, plums contain large amounts of phenolic compounds and flavonoids that have natural antioxidant activity which is useful to human health. The study aimed to evaluate the effects of foliar sprays with salicylic acid (SA), putrescine (PUT) and moringa leaf extract (MLE) on the fruit quality attributes and bioactive compounds of 'Golden Japan' plums under cold storage conditions. Plum trees were sprayed twice; at fruit set ...

Evaluation of breeding strategies for polledness in dairy cattle using a newly developed simulation framework for quantitative and Mendelian traits
(2016-06-29)
Background: Intensified selection of polled individuals has recently gained importance in predominantly horned dairy cattle breeds as an alternative to routine dehorning. The status quo of the current polled breeding pool of genetically-closely related artificial insemination sires with lower breeding values for performance traits raises questions regarding the effects of intensified selection based on this founder pool.
Methods: We developed a stochastic simulation framework that combines the stochastic simulation ...

The impact of irrigation distribution uniformity and mulching soil on vegetative growth and yield of sweet fennel and squash plants
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-03-31)
Water shortage under climate change impacts performed the driving forces to enhance the agricultural practices to maximize the food production. Improve the distribution of irrigation water with mulching soil to satisfy the plants needs and provide optimum conditions for production consider the main objective of the current study. Two experiments of the study were conducted out at Central Laboratory for Agriculture Climate (CLAC), Agriculture Research Center, Egypt during winter and spring seasons of 2016/2017 and ...

Africa’s future: Demarginalizing urban agriculture in the era of climate change
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-06-05)
Africans are migrating to cities. With the continent’s cities projected to double in population by 2050, the issue of food insecurity in urban areas is increasingly becoming a major concern. To sustain this urban explosion, the question of how to maintain constant food supply to urban residents remains an urgent priority since these locations do not always get access to adequate food. There has, however, been little work on examining urban agriculture (UA) as an alternative means of reducing hunger in Africa, especially ...
