A literature review as an aid to identify strategies for mitigating ostreid herpesvirus 1 in Crassostrea gigas hatchery and nursery systems ArchiMer
Rodgers, Chris; Arzul, Isabelle; Carrasco, Noèlia; Furones Nozal, Dolores.
An understanding of husbandry strategies and any associated risk factors is important for designing management control measures that can reduce mortality in Pacific oysters, Crassostrea gigas, caused by ostreid  herpesvirus 1 (OsHV-1). The type of culture facility can be considered in relation to the potential pathways that could lead to the entry of a pathogen and its survival. In addition, the animal host (e.g. age, physiological state,  selective breeding programmes), husbandry procedures (e.g. stocking density), the pathogen itself (e.g. pathogenicity, virulence) and environmental effects (e.g. temperature) represent other relevant interconnected factors. However, all these factors provide valuable background information for outlining the mitigation...

Biophysical and economic models for assessing impacts of change on grazingland ecosystems AGRIAMBI
Souza Neto,José de; Conner,James R.; Stuth,Jerry W..
PHYGROW, a hydrologic-based forage simulation model, was parameterized to represent a typical South Texas ranch engaged in the production of cattle and meat goats with an indigenous population of white-tailed deer. Forage production and associated stocking rates for two cattle:goat ratios were simulated with POPMIX for 20 years. Two ten-year weather scenarios, one representing normal conditions (30% drought years) and one representing dryer weather conditions (50% drought years) were analyzed. Management decision rules (ASPC) were developed for the region to produce estimates of annual animal production and operating costs for the enterprises on each of the four scenarios. These performance and cost data were then used as input into FLIPSIM, a firm level...

Evaluation of hydraulics characteristics and management strategies of subsurface drainage system in Indira Gandhi Canal Command CIGR Journal
Rohitashw Kumar; SKUAST-K; S. R Bhakar; P. K. Singh; Department of Soil & Water Engineering, CTAE, Udaipur, India.
The present study revealed the performance of subsurface drainage systems for long-term sustainability of irrigated agriculture.  The performance of subsurface drainage systems was evaluated on the basis of drain spacing equations for disposal of effluent and hydraulic characteristics of envelop materials, like entrance resistance created by envelop and hydraulic conductivity.  Three important synthetic envelopes, HG 22, SAPP 240 and CAN 2 were tested in laboratory using sand tank model and permeability apparatus to compare their performances in terms of entrance resistance and hydraulic conductivity of soil envelope system.  The hydraulic conductivity for SAPP 240 filter was found the highest and entrance resistance the lowest....

Morphological adaptations of signal grass in response to liming and cutting severities Rev. Ciênc. Agron.
Pereira,Lilian Elgalise Techio; Passos,Bruna Scalia de Araújo; Herling,Valdo Rodrigues; Luz,Pedro Henrique de Cerqueira; Avanzi,Junior Cesar.
ABSTRACT Changes in morphological composition and in the plant population were evaluated during late spring, summer and autumn, in swards of Brachiaria decumbens cv. Basilisk in response to liming (C0.0, without liming; C0.7, limestone amount equivalent to 0.7 ton ha-1; and C1.0, limestone amount equivalent to 1.0 ton ha-1), which were subjected to severe or lenient cutting (40 or 60% of the pre-cutting height, respectively). Increased limestone doses did not result in higher herbage mass (HM), leaf area index (LAI) or proportion of leaves (%L) in the pre-harvest. However, lower proportion of dead material was registered in C0.7 treatment. The treatments C0.0 e C0.7 had higher %L during late spring and summer when associated to severe cutting regimes...

Risk management strategies by Australian farmers: two case studies AgEcon
Nguyen, Nam C.; Wegener, Malcolm K.; Russell, Iean W.; Cameron, Donald; Coventry, David; Cooper, Ian M..
Australian farmers operate in one of the most risky farming environments in the world. They have to cope with numerous sources of risk including weather uncertainty, variable market prices, and institutional changes in their business management. This paper reports results from two case studies undertaken to examine the issues of farming risks and risk management strategies in Australia. The first case study found that unpredictable weather, financial risk, marketing risk, and personal risk were regarded as the major sources of risk among farmers in the Upper Eyre Peninsula of South Australia. The main risk management strategies used by farmers in that region included diversifying crop varieties, adopting minimum tillage farming practices, minimising the...

The Impact of Participation in Cooperatives on the Success of Small Farms AgEcon
Mishra, Ashok K.; Tegegne, Fisseha; Sandretto, Carmen L..
This study identifies and analyzes factors that contribute to the success of small farms. Particular attention is given to the effect of participation in marketing and supply cooperatives on the success of small farms. Using modified net farm income per dollar of assets and operator’s labor and management income as measures of success, results show participation in marketing and supply cooperatives is positively correlated with success. Further, analysis findings indicate farm size, controlling for variable and fixed costs, type of ownership, management strategies used, working off the farm, and age of the operator are important factors that influence profitability (modified net farm income per dollar of assets and operator’s labor and management income)...
