Ricecheck, an extension program for rice developed by the NSW Department of Primary Industries, is based on eight best management practice recommendations (“key checksâ€) considered essential for achieving high yields. The program comprises grower meetings, monitoring crops, keeping...

Acid and acidifying soils occur extensively in Australia. Currently, some 90 million hectares of agricultural land in Australia is considered to be acidic and around 35 million hectares are considered to be highly acidic which is both a serious agricultural and environmental problem. The nature,...

The occurrence of low night temperatures during reproductive development is one of the factors most limiting rice yields in southern Australia. Yield losses due to cold temperature are the result of incomplete pollen formation and subsequent floret sterility. Researchers have found that in 75%...

The new AWB Ltd payment system for wheat grades has changed the incentives for farmers to grow and market wheat varieties in Australia. Based around standard quality characteristics, the payment system provides incremental premiums and discounts for deviations in protein and screenings around...

Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia....

Ricecheck, a best management practices extension program for rice production in Australia, was developed by the NSW Department of Primary Industries advisory staff, Finley, in 1986. The program is based on eight best management practice recommendations called ‘Key Checks’ that are considered...

Spatial diversity indicators may serve policymakers as they seek to manage crop genetic diversity and externalities associated with diffusion of some genetically modified crops. This paper adapts ecological indices of spatial diversity to area distributions of modern wheat varieties in...

In determining the economic impact of a possible outbreak of the quarantinable wheat disease Karnal Bunt, an examination was made of the detailed components of the costs involved. The costs were classified as: (a) Direct costs (yield and quality losses); (b) Reaction costs (export bans, quality...
