Short-term impacts of tillage and fertilizer treatments on soil and root borne nematodes and maize yield in a fine textured cambisol
(Society of Nematologists, 2018)
tc. Conservation agriculture (CA) based on the principles of minimum soil disturbance, crop residue retention, and crop rotation has been the focus of intensive research in recent years. A study was carried out to determine ...
Precision for smallholder farmers : a small-scale-tailored variable rate fertilizer application kit
Precision agriculture technology at the hands of smallholder farmers in the developing world is often deemed far-fetched. Low-resource farmers, however, are the most susceptible to negative changes in the environment. ...
A simplified irrigation pump testing method for developing countries : a case study in Bangladesh
(John Wiley and Sons, 2018)
Much of South Asia experiences a monomodal rainfall pattern with a distinct dry season following the annual monsoon. Enabling irrigation during the dry season has therefore been crucial in assuring improved productivity ...
Conservation agriculture with trees amplifies negative effects of reduced tillage on maize performance in East Africa
Conservation agriculture (CA) is widely promoted in sub-Saharan Africa both in open fields and in agroforestry where the practice is known as ‘conservation agriculture with trees’ (CAWT). Although advantages and disadvantages ...
Unpacking the push-pull system : assessing the contribution of companion crops along a gradient of landscape complexity
(Elsevier Masson, 2018)
The push-pull system, a stimulo-deterrent cropping strategy consisting of intercropping cereals with herbaceous legumes and surrounded by fodder grasses, is presented as a promising crop diversification strategy for ...
Capturing farm diversity with hypothesis-based typologies : an innovative methodological framework for farming system typology development
(Public Library of Science, 2018)
Creating typologies is a way to summarize the large heterogeneity of smallholder farming systems into a few farm types. Various methods exist, commonly using statistical analysis, to create these typologies. We demonstrate ...
Nitrous oxide (N2O) flux responds exponentially to nitrogen fertilizer in irrigated wheat in the Yaqui Valley, Mexico
(Elsevier Masson, 2018)
The Yaqui Valley, one of Mexico's major breadbaskets, includes ?230,000 ha of cultivated, irrigated cropland, with two thirds of the area planted annually to spring wheat (Triticum turgidum). Nitrogen (N) fertilizer ...
Increasing yield stability and input efficiencies with cost-effective mechanization in Nepal
Nepal is at a crossroads of diminishing farm-labor and inadequate investment into farming operations that, among other factors, have stagnated domestic wheat yield. Cultural and economic constraints have hindered the ...
Advances in crop insect modelling methods—Towards a whole system approach
A wide range of insects affect crop production and cause considerable yield losses. Difficulties reside on the development and adaptation of adequate strategies to predict insect pests for their timely management to ensure ...
Indirect contributions of forests to dietary diversity in Southern Ethiopia
(Resilience Alliance, 2017)
We assess whether forests contribute indirectly to the dietary diversity of rural households by supporting diverse agricultural production systems. We applied our study in a landscape mosaic in Southern Ethiopia that was ...
