Potential causes of postharvest losses, low-cost cooling technology for fresh produce farmers in Sub-Sahara Africa

The aim of this review was to identify the causes of postharvest losses (PHL) in fruit and vegetables in relation to small-scale farming in sub-Saharan Africa (SSA). The reduction of PHL can improve food security at household level. Farmers involved in small-scale production of fresh produce experience high PHL due to physiological deterioration associated with technical, biological and environmental factors and lack...

Nitrogen value of stockpiled cattle manure for crop production

Cattle manure is a common source of fertilizer throughout Sub-Saharan Africa given problems with supply and pricing of inorganic fertilizers. The optimum rate of manure to use is often unknown and further compounded by variable N contents arising from long periods of stockpiling. This study investigated the rates of cattle manure required to optimize plant growth at different N contents arising from different storage...

Agro-morphological response of some groundnut genotypes (Arachis hypogaea L.) in water deficit conditions

Groundnut is a crop that can be grown under varied production conditions (in intercropping or rotation with cereals). In Niger, the production of groundnut is decreasing over the year due to drought and low soil nutrients. In this work, an agro-morphological evaluation of five groundnut genotypes (55-437, ICG12697, ICG4750, JL24 and ICG8751) under water deficit was carried out in order to identify the best performing...
