A study was carried out in 2011/2012 and 2012/2013 growing seasons in Kandeu and Manjawira Extension Planning Areas (EPAs) in Ntcheu district, Central Malawi, to determine maize response to crop residue incorporation from legume cropping systems and

The global nitrogen (N) cycle is markedly, and increasingly, influenced by anthropogenic inputs. A large unknown remains the quantity of biological N fixation (BNF) inputs derived from agriculture. This leads to major uncertainties in modeling reacti

It has recently been shown that root cortical aerenchyma (RCA) formation substantially reduces the metabolic costs of soil exploration, thereby improving rooting depth, water capture, and plant growth under drought. The objectives of this study were

La diversification des cultures a une longue histoire en Afrique, comme base de systemes agraires resilients et durables. Cependant, les resultats n’ont pas toujours ete positifs. Le climat erratique et le changement climatique requierent de souten

Leguminous agroforestry (AF) species have been investigated and promoted in Malawi as a means to improve soil quality and maize (Zea mays) yields. Our objective was to determine whether AF systems' recommendations that solely consider impacts on aver

In Malawi, agroforestry is very promising for N replenishment; however, there are still large variations in the performance of these agroforestry technologies on farmers’ fields. A study was conducted on-farm to determine the influence of three lan

In Malawi, intensive production of maize (Zea mays) is pursued on over 60% of smallholder land, yet application of nutrients is almost nil. To improve adoption of soil productivity-enhancing technologies, two participatory methods were pursued: (i) a

Forage responses to stocking rates and seasons were determined over a one-year period. The experimental design consisted of three stocking rates namely, light (2.0ha LSU-1), moderate (1.25ha LSU-1) and heavy (0.5ha LSU-1) and four seasons (autumn, wi
