Mapping field-scale yield gaps for maize: An example from Bangladesh
Accurate estimation of the size and spatial distribution of the yield gap has many practical applications, including relevance to precision agriculture and technology targeting. The objectives of this study were to illustrate ...
Effects of light environment on maize in hillside agroforestry systems of Nepal
Maize (Zea mays L.) is the most important staple food in the mid-hills region of Nepal. The mid-hills are characterized by steeply sloping land and complex farming systems where crops, livestock and trees are inseparable ...
Rapid gains in food security from new maize varieties for complex hillside environments through farmer participation
This is a follow-up study of two previous papers in this series in which we discussed the effectiveness of participatory varietal selection (PVS) and community-based seed production (CBSP). In this paper we present from ...
Potassium supplying capacity of diverse soils and K-use efficiency of maize in South Asia
Increased nutrient withdrawal by rapidly expanding intensive cropping systems, in combination with imbalanced fertilization, is leading to potassium (K) depletion from agricultural soils in Asia. There is an urgent need ...
Analysis of genetic diversity in the North Eastern Himalayan (NEH) maize landraces of India using microsatellite markers
Population DNA fingerprinting of 48 selected North Eastern Himalayan (NEH) landrace accessions was undertaken using 41 polymorphic fluorescent dye-labelled microsatellite/Simple Sequence Repeat (SSR) markers, using a DNA ...
Molecular marker-assisted breeding options for maize improvement in Asia
Maize is one of the most important food and feed crops in Asia, and is a source of income for several million farmers. Despite impressive progress made in the last few decades through conventional breeding in the ?Asia-7? ...
