| Soil acidification is one of the major forms of soil degradation in higher rainfall areas of the tablelands of NSW. A grazing experiment was conducted near Sutton, NSW, to assess the effect of various rates of superphosphate, lime, sewage ash and stocking rates on wool production and sustainability between 1999 and 2008. The results from the discounted cash flow analysis show that the net present value of the treatment without lime, the lower rate of superphosphate and the lowest stocking rate returned the highest net present value of $266.30/ha. Raising the application of superphosphate from 125kg/ha every two to three years to 250kg/ha every year on un-limed and limed soil reduced the net present value by $278.70/ha and $249.30/ha, respectively. The... |

| Different patterns of nutrition during pregnancy and lactation can influence cow productivity and the performance of their offspring. An experiment was conducted on the North Coast of NSW whereby “low” and “high” pasture nutritional systems were imposed on a herd of Hereford cows during pregnancy, and then again from birth to weaning, with a crossover design also imposed to select offspring with extremes of growth to birth and/or weaning. Thus, four growth groups resulted – low-low, low-high, high-low, and high-high. Piedmontese and Wagyu bulls were used. After weaning, these offspring were grown out on the NSW Northern Tablelands and then finished to heavy market weights in a feedlot. The results of the experiment indicated that restricted early-life... |

| Florida ranked ninth in the U.S. in agricultural receipts for the year 2000, and ranked first or second in receipts for 12 of the nation's top 25 agricultural commodities. Ten of these twelve leading agricultural commodities were fresh fruits or vegetables, and combined, they represented over 45 percent of the state's agricultural receipts in 2000. Despite Florida's preeminent standing as a producer of fresh fruits and vegetables, it's future leadership in this industry is less clear. In real terms, Florida's annual agricultural receipts have declined from $7.41 billion in 1992, to $6.42 billion in 2001. In 2000, receipts fell by over $521 million, the sharpest one-year drop since 1990. The overall trend in fresh vegetable receipts for the State has been... |

| This paper explores socio-demographic, economic and behaviour factors influencing body mass index (BMI) amongst 20 to 64 year old adults in Canada. BMI scores in Canada have increased, with gains stemming from disproportionate increases in female BMI. Econometric results indicate higher BMI scores for males, those born in Canada, those in food insecure homes and whites. Age-gender interactions suggest different patterns of BMI adjustment over the life of males and females; a pronounced inverse quadratic relationship between with age and male BMI is noted, while female BMI increases with age. Education, used as a gauge of inequality, is inversely related to BMI, while income has a muted effect. BMI is inversely related to level of physical activity, an... |

| Mushrooms have been grown commercially on many different substrates for years, usually agricultural by-products such as straw or stover. Increased popularity for specialty mushrooms with consumers has led to increased production and great demand for economic substrates. Oyster mushrooms are easier to grow relative to other types of mushrooms and their production has increased dramatically in recent years. This study examines the economic feasibility of using soybean hulls as a primary substrate for oyster mushrooms, replacing traditional wheat straw. The study uses a cost-benefit analysis to determine an optimal substrate based on yield and the number of crops harvested per year. The study shows that soybean hulls, combined with corn gluten or... |

| Taking Wuqi country, shanxi Province as an example, this paper is based on the introductions of the researched regions and according to the planting model and some factors influencing economy. After systematic analysis and selection, it selects ecological forestry, wood-grass-husbandry, wood-grass-husbandry, wood-medicine, economic forestry and greenhouse vegetable these five models of returning farming to grass, with Wuqi town, Baibaotown, Wu Cangbao county, Xinzhai county, Xuecha county and Wugu town these five sites as examples. This paper has carried out a research on these 5 models at country, town and household levels through Participatory Rural Appraisal and Document Search to gain the related data. And making a comparison on the contribute of the 5... |

| It is notoriously difficult to assess the economic value of research aimed at improving research capacity, particularly in enhancing human capital. In this paper, a framework is developed and an analysis is undertaken of the value of training for scientists in wheat rust resistance in India. The value of the training is assessed through marginal analysis of the improvement in the level of disease resistence flowing from the increased capacity. On that basis, the value of programs to build human capacity through training or further education can be estimated. While such estimates need to be highly qualified, they provide a basis for quantifying the value of R&D capacity building. |
