This study examined the impact of improved rice varieties adoption on rice productivity and farming households’ welfare in Nigeria using a cross sectional data of 481 rice farmers drawn from three states to represent the major rice producing ecologies (Irrigated, upland and lowland) in Nigeria. Access to seed was found to be one of the significant determinants of adoption. Poverty incidence was...

The Agricultural Production Systems Simulator (APSIM) is a mature and stable modelling framework used widely in Australia and elsewhere in the domain of farming systems research and extension. It is capable of simulating a diverse range of farming systems including broadacre dryland and irrigated cropping, small holder farming and on-farm agroforestry systems. This includes the interaction of t...

Human kind invented agriculture 10,000 years ago. After a long mile, nowhere in the world has agriculture made an impact as it has in India.

Olympe is a software developed by INRA, IAMM and CIRAD to model and simulate cropping and farming systems functioning. As it is based on economic analysis that considers contextual components, it enables to identify and model one or several farmers " strategies and trajectories. Prospective analysis is also possible, including prices volatility or climatic events and their impacts. This tool wa...

Changes in soil physical and chemical properties were evaluated in several on-farm studies located in rainfed, hardsetting red Al®sols (Ferric Luvisols) and in irrigated, self-mulching Vertisols (Chromic Vertisols) of eastern Australia. The objective of the studies was to evaluate changes in soil physical and chemical properties with time under commercial farming situations where changes had be...
