Economic Potential for Nutritional Improvement in Feed Grains AgEcon
Brennan, John P.; Singh, Rajinder Pal; Bialowas, Adam.
Feed grains researchers have abundant technical opportunities to select various options for improvement of nutritional characteristics of feed grains. Choosing between those opportunities is a difficult issue for research funding organisations. In this paper, efforts to address the relative economic benefits from the different options for feed grains nutritional improvement are reported. The economic benefits arising from nutritional improvements in various feed grains are examined and compared to the benefits from increasing yields of the feed grains rather than improving their nutritional value. The results of the analysis of these options are presented in an economic surplus framework that enables the major beneficiaries and the relative gains for the...

Economic Issues in Assessing Research Priorities in Feed Grains Nutrition AgEcon
Brennan, John P.; Singh, Rajinder Pal; Singh, Inder Pal.
Researchers have abundant technical opportunities to select various options for improvement of nutritional characteristics of feed grains. Choosing between those opportunities is a difficult issue for research funding organisations. In this paper, an attempt to address those research resource allocation issues is reported. The approach to use in analysing improvements in the feed quality of grains is discussed. By defining the problem as a cost reduction for the livestock industries, the impact of improvements in grain nutrition can be defined by their impact on the least-cost feed rations for different livestock categories. Using that approach, the benefits of improved feeds can be evaluated, and research priorities can be determined on the basis of which...

Economic potential for improving the nutritional characteristics of feed grains AgEcon
Brennan, John P.; Singh, Rajinder Pal; Singh, Inder Pal.
A comprehensive set of potential new feed grains for Australia was evaluated to help establish the options with the highest priorities for research. The cost-reducing impacts of the different options were analysed using a linear-programming model that determined the least-cost feed rations for the different livestock industries. Economic welfare analysis was then used to estimate the size and distribution of the benefits of research from the feed grains quality-improving research. The analysis revealed that there are only limited opportunities to improve the productivity and competitiveness of Australia’s livestock industries by improving the nutritional characteristics of feed grains.

An Assessment of the Economic, Environmental and Social Impacts of NSW Agriculture's Advisory Programs in Water Use Efficiency AgEcon
Crean, Jason; Shaw, Anna; Singh, Rajinder Pal; Mullen, John D..
An assessment of the economic, environmental and social impacts of extension activities by NSW Agriculture related to water use efficiency is reported. The main vehicle for these extension activities has been a four day vocational course delivered to about 4,400 irrigators under the auspices of the WaterWise on the Farm Initiative (WWF). We focused on four industry/regional complexes - the cotton industry in northern NSW, the lucerne industry in central and northern NSW, the cherry industry and the viticulture industry in southern NSW - where WWF was known to have had an impact. Generally the impact of WWF was to advance the adoption of water use efficient technologies by several years. The investment by NSW Agriculture in year 2002 dollars is likely to be...

The implications of policy settings on land use and agricultural technology adoption in North-West India AgEcon
Millham, Nick; Crean, Jason; Singh, Rajinder Pal.
The irrigated rice-wheat cropping system is the predominant and most profitable farming system in north-west India, especially in Punjab. However, there are growing concerns about the environmental effects of the system, particularly with the practice of burning rice stubbles, due to its adverse effects on human health and air pollution. In this paper we consider the wide array of policy settings that tend to favour current land uses and management practices and their impact on the farming system over time. As part of an ACIAR-funded project, we assess the significance of these policies with a view to considering what additional or alternative policies could be put in place to encourage the adoption of approaches or technologies directly concerned with...

Economic Analysis of Improving Cold Tolerance in Rice in Australia AgEcon
Singh, Rajinder Pal; Brennan, John P.; Farrell, Tim; Williams, Robert L.; Rienke, Russell; Lewin, Laurie; Mullen, John D..
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% of years, rice farmers suffer losses between 0.5 and 2.5 t/ha. Research is being undertaken to identify overseas rice varieties, that are cold tolerant under the local weather conditions and by using those genotypes as parent material, develop cold tolerance varieties of rice. A yield simulation model was used to measure reduction in losses due to cold at different minimum threshold temperatures, while the SAMBOY Rice model was used to measure the costs and returns...

An Assessment of the Economic, Environmental and Social Impacts of the Ricecheck Program AgEcon
Singh, Rajinder Pal; Brennan, John P.; Lacy, John; Steel, Felicity.
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 essential for achieving high yields. Economic analysis of the program reveals that there are significant financial, social and environment benefits from the adoption of the program. The results further reveal that the funds invested since 1986 by both NSW Department of Primary Industries and the Rural Industries Research and Development Corporation have been sound investments.
