Rainfall risk and the potential of reduced tillage systems to conserve soil water in semi-arid cropping systems of southern Africa
(AIMS Press, 2016)
Improvement of household food security in the Limpopo Basin has been elusive due to a combination of factors related to information and market constraints, but also farmers’ risk aversion induced by the high variability ...
Drought susceptibility of modern rice varieties : an effect of linkage of drought tolerance with undesirable traits
(Nature Publishing, 2015)
Green Revolution (GR) rice varieties are high yielding but typically drought sensitive. This is partly due to the tight linkage between the loci governing plant height and drought tolerance. This linkage is illustrated ...
Weedy rice: An emerging threat for direct-seeded rice production systems in India
(OMICS Publishing Group, 2013)
Rice is an important cereal crop in India for food security. Conventional practices for rice production (puddled transplanting) are labour-, water-, and energy-intensive. All of these resources are becoming increasingly ...
Effects of crop residues and reduced tillage on macrofauna abundance
Conservation agriculture is promoted to safeguard resilient properties of soils and to reclaim degraded arable lands. This is achieved through creating necessary conditions for fauna recolonisation. A study was carried out ...
Farmers' willingness to pay for index based crop insurance in Pakistan: a case study on food and cash crops of rain-fed areas
In Pakistan, agriculture is vulnerable to multiple risks, especially in the rain-fed areas. The crop insurance can serve as a useful tool to manage risks in the rain-fed areas of Pakistan. This study has assessed farmers? ...
Evaluation of fungal isolates as possible biocontrol agents against Striga hermonthica
Striga hermonthica is a parasitic weed which largely constraints maize and sorghum production in Western Kenya. The weed mostly invades small scale farms and depending on severity, it may cause damage ranging from 10% to ...
Soil water crop modeling for decision support in millet-based systems in the Sahel : a challenge
(Academic Journals, 2014)
Food insecurity in the Sahelian environment was extensively shown to be a result of low soil fertility and high climate risks. But decisions and recommendations made from the great wealth of research have little been adopted ...
Mapping smallholder wheat yields and sowing dates using micro-satellite data
Remote sensing offers a low-cost method for developing spatially continuous crop production statistics across large areas and through time. Nevertheless, it has been difficult to characterize the production of individual ...
A global analysis of alternative tillage and crop establishment practices for economically and environmentally efficient rice production
(Nature Publishing Group, 2017)
Alternative tillage and rice establishment options should aim at less water and labor to produce similar or improved yields compared with traditional puddled-transplanted rice cultivation. The relative performance of these ...
Direct Nitrous Oxide emissions from Tropical And Sub-Tropical Agricultural Systems : a review and modelling of emission factors
(Nature Publishing Group, 2017)
There has been much debate about the uncertainties associated with the estimation of direct and indirect agricultural nitrous oxide (N2O) emissions in developing countries and in particular from tropical regions. In this ...
