Maize streak virus: A review of pathogen occurrence, biology and management options for smallholder farmers

Maize streak disease is a major threat to cereal crops amongst smallholder farmers in sub-Saharan Africa causing up to US$480 million losses annually. It is caused by Maize streak virus (MSV), a geminivirus that is indigenous to Africa. The virus is transmitted by at least 11 Cicadulina species, with Cicadulina mbila being the main vector. In addition to cereals, the virus also infects wild grasses. There are 11 known...

Comparative analysis of rice milling strategies: Evidence from rice millers in Benin

Milling and related activities are central to the improvement of the quality of locally produced rice in many African countries. Fee-based milling and paddy buying-milling-selling services are among the strategies used in the milling business. The Heckman two-stage model and gross profit method were used on survey data, collected in 2011 on rice millers in major rice-producing regions of Benin to identify the factors...

Effect of precision land levelling and permanent raised bed planting on soil properties, input use efficiency, productivity and profitability under maize (Zea mays) – wheat (Triticum aestivum) cropping system

Precision land leveling with permanent raised bed planting with recommended dose of NPK can be used to improve crop yield, water and nutrient use efficiency over the existing traditional land leveling with flat beds planting with recommended dose of NPK practices. The objective of the present study was to establish an understanding of maize-wheat rotation yield and input use efficiency can be improved and how land...

Studies on bio-ecology and voracity of leaf roller (Diaphania indica Saunders, Lepidoptera: Pyralidae) on pointed gourd (Trichosanthes dioica Roxb.)

Field and laboratory studies have been carried out on the bio-ecology of Diaphania indica Saund. Correlation coefficient with all seven weather factors considered in the present study indicated that there existed significantly high negative correlation with five factors viz. temperature (°C), relative humidity (%), rainfall and soil temperature (°C) but bright sun shine hours that did bear significant weak...
