Strategies for nutrient management in irrigated and rainfed lowland rice systems soils, spatial and temporal variability of water availability, high risk of crop failure, and fewer resources for capital expenditure, rainfed lowland rice farmers give priority to reducing risk. Farmers’ ability to invest in cost-intensive innovative technologies is limited. As a consequence, the

Interpreting fertilizer use efficiency in relation to soil nutrient-supplying capacity, factor produed; GY was also measured in that area. In each domain, GY in unfertilized plots varied considerably among farms, as the range between maximum and minimum values within each domain was at least 2.8 t ha., thus of comparable magnitude to mean GY for these plots. Fertilizer N rates varied from 36 to 24

On-farm adaptation of knowledge-intensive nitrogen management technologies for rice systemsits high cost, it is a practically useful tool for field researchers, extension specialists, and crop consultants who do not have access to well-equipped laboratories. On-farm, adaptive research is in progress in three countries to adapt the chlorophyll meter technique for transplanted and wet-seede
