Reconstituting family transitions of Sahelian western Niger 1950-2000: an agent-based modelling approach in a low data context
(Cybergeo : European Journal of Geography, 2013)
This research analyses the impacts of the family organization on the diversity of income sources and the sustainability and the dynamics of rainfed farming systems of Sahelian Niger, through an individual-centred agent-based ...
The growing commitment to training, at a center devoted originally and primarily to research, has evolved as an essential complement to the development of improved agricultural technologies.
Dissecting genome-wide association signals for loss-of-function phenotypes in sorghum flavonoid pigmentation traits
(Genetics Society of America, 2013)
Genome-wide association studies (GWAS) are a powerful method to dissect the genetic basis of traits, though in practice the effects of complex genetic architecture and population structure remain poorly understood. To ...
The return of medic
Medic, a forage legume that made good as an Australian immigrant, is going back home to Mediterranean cereal fields with the help of CIMMYT. In cereal-legume rotations, medic boosts cereal yields by raising soil nitrogen ...
Notes on the role of rural Pakistani women in farming in the Northwest frontier province
It is gradually being accepted that women in Pakistan make a direct contribution in the farming sector. The extent and nature of their contribution, however, is not fully known to development planners. In the past, very ...
Conservation agriculture systems for Malawian smallholder farmers: long term effects on crop productivity, profitability and soil quality
(Cambridge University Press, 2013)
Conservation agriculture (CA) systems are based upon minimal soil disturbance; crop residue retention and crop rotation and/or intercrop association are increasingly seen to recycle nutrients, increase yield and reduce ...
Potential technology and research needs for rainfed maize production in drought prone environments of Southern Africa
In southern Africa, semi-arid areas (here simply defined as areas with less than 700 mm but more than 350 mm of rainfall per annum) can be found from around 100 m to over 1,400 m above sea level. The semi-arid areas most ...
Extent and causes of low yield in maize planted late by smallholder farmers in sub-humid areas of Zimbabwe
Diagnostic work was undertaken during 1987-91 to determine the area of maize planted late by smallholder farmers in sub-humid (Natural Regions 2 and 3) communal areas of Zimbabwe, the grain yield losses encountered, and ...
Response of four maize varieties to nitrogen at Lisungwi extension planning area, Mwanza, Malawi
Lisungwi Extension Planning Area (EPA) in Mwanza Rural Development Project (RDP) has insufficient rainfall for optimum maize growth. The soils are generally low in organic matter, nitrogen, phosphorus, and magnesium. Farmers ...
On-farm experimentation with intercrops: a summary of issues from a workshop held in Malawi
Most intercropping research has been conducted on experiment stations with the aim of proving or understanding the efficiency or advantage of intercropping systems, or of designing new systems on the basis of biological ...
